Latest / Reformed Thinking / The Laughter of the Impossible: When God Visits (Genesis 21:1–7)
Transcript
- 0:00Welcome to Reform Thinking. I am your host and today we are
- 0:04walking into a room that no one really puts on their vision
- 0:07board, but I think everyone ends up sitting in eventually.
- 0:10Oh yeah, it's the room with the worst magazines and the slowest
- 0:14clock you've ever seen. We are talking about the waiting
- 0:16room, but we aren't just talking about, you know, waiting for a
- 0:19table at a restaurant or for some test results, though those
- 0:23feelings are definitely part of it.
- 0:24We're looking at the theological waiting room that that season
- 0:27where you believe God has made a promise.
- 0:29You know what his word says, but your reality it's just screaming
- 0:34the opposite. It's the gap, the gap between
- 0:37the Amen of the prayer and the actual tangible answer.
- 0:41And for the couple we're looking at today, that gap wasn't a week
- 0:44or a month. No, it was 25 years. 25 years.
- 0:48Just let that sink in. We are, of course, talking about
- 0:51Abraham and Sarah, and we're going to be focusing in really
- 0:54drilling down on Genesis chapter 21 verses one through 7.
- 0:58This is the moment, the climax of their entire story up to this
- 1:01point, the birth of Isaac. It really is the moment the
- 1:04credits would roll if this were a Hollywood movie.
- 1:07You know, fade to black, happy music.
- 1:09Right, the happy ending. But because this is the Bible,
- 1:13and specifically because we're looking at it through the lens
- 1:15of Reformed theology, we can't just pop the champagne and say,
- 1:19look, a baby. We have a stack of sources here,
- 1:22sermons, theological essays, commentaries that all argue this
- 1:26passage is about something much, much bigger than a geriatric
- 1:30pregnancy. It's about the very nature of
- 1:32God's memory. And that's the real question
- 1:34hanging over the 1st 20 chapters of Genesis, isn't it?
- 1:38And if we're honest over our own lives too.
- 1:41The question is, has God forgotten?
- 1:43When the calendar pages just keep turning and the silence
- 1:46from heaven gets, well, it gets loud.
- 1:49Does God still remember what he said he would do?
- 1:51So our mission today is to answer that.
- 1:53We're going to dig into the text to see how it answers that
- 1:56accusation, that fear that God has checked out.
- 1:59And the sources we're using, they set up this massive
- 2:01conflict right out of the gate. They contrast what they call the
- 2:04idol of immediacy. Which I think is the God of the
- 2:0721st century. It has to be everything now,
- 2:09everything fast. They contrast that idol with the
- 2:12appointed time of God. We love the immediate.
- 2:15We worship efficiency. But this text is going to force
- 2:19us to slow down. It's going to make us look at
- 2:21how God operates when His timeline just doesn't make any
- 2:25sense to us. Not from our perspective,
- 2:26anyway. OK, let's just get right into
- 2:28the text. Genesis 21 verse one.
- 2:30I'm going to read it and I want you to just, you know, tear it
- 2:32apart for us. The Lord visited Sarah as He had
- 2:35said, and the Lord did to Sarah as he had spoken.
- 2:39Right, so that sentence, it seems so simple in English.
- 2:42Subject, verb, object. The Lord visited Sarah.
- 2:46Done. Pretty straightforward.
- 2:48But the sources all point out that in the original Hebrew, the
- 2:51syntax itself is doing some very heavy theological lifting.
- 2:55The author, Moses, he puts the covenant name of God, Yahweh or
- 2:59the Lord in what's called the emphatic position.
- 3:02OK, hold on, emphatic position. I hear that term and I
- 3:05immediately think of someone like shouting or using all caps.
- 3:09What does that actually look like in the sentence structure
- 3:11itself? That's a great question.
- 3:13In English our word order is pretty fixed right?
- 3:16You can't just say Sarah the Lord visited.
- 3:18It sounds wrong. Broken.
- 3:20But in Hebrew you have more flexibility.
- 3:24You can move words around to signal to the reader what
- 3:26matters most. And here Moses shoves the name
- 3:30Yahweh to the very front of the sentence.
- 3:32Before you see Sarah, before you see the verb visited, before you
- 3:36see any action at all, you run straight into God.
- 3:39So it's like a spotlight. It is a spotlight that leaves
- 3:42everything else in the shadows for a split second.
- 3:45Think about a movie before you even see the actors over the
- 3:47set. Sometimes the screen just goes
- 3:49black and the director's name appears in huge letters.
- 3:53Ah. OK, I see that.
- 3:55That's exactly what's happening here.
- 3:56Moses is signaling from word one that the primary actor, the main
- 4:00character in this event, is not Sarah.
- 4:02It isn't Abraham, and it is most certainly not their biological
- 4:06fitness or lack thereof. The subject of the sentence,
- 4:09then, is also the subject of history.
- 4:10That's it, it's the Lord. And that one little distinction,
- 4:13it just changes how we read the whole story.
- 4:16Because if the sentence started with Sarah, our first instinct
- 4:19might be to look at her. Her health, her diet, her
- 4:22mindset. We'd be looking for the human
- 4:24cause. But by starting with the Lord,
- 4:27the text forces us to look up. It forces us to start with God's
- 4:31character, not human circumstances.
- 4:33OK, so that brings us to the verb.
- 4:36The text says the Lord visited Sarah.
- 4:38Now I have to say, the English translation visited just feels a
- 4:42bit weak here. It's so weak it's almost
- 4:44misleading. It sounds so polite, like oh I
- 4:46visited my grandma for tea. It sounds like a social call.
- 4:49A quick pop in. Hey, just checking on you,
- 4:51seeing how things are going. But the Hebrew word is pakkad,
- 4:54and pakkad is well, one source called it volcanic.
- 4:57Volcanic in what way? It implies a divine intervention
- 5:00that completely alters the fabric of reality.
- 5:03It isn't just God looking in on the situation, it's God stepping
- 5:06in to change it. Fundamentally, it's an
- 5:08inspection with intent to act. So it's not a passive look, it's
- 5:12an active intrusion. A powerful one.
- 5:14We see the same word pakod used in Exodus 32 when God visits the
- 5:20iniquity of the people upon them.
- 5:21It's a word of judgment there. So it can be negative.
- 5:23Oh. Absolutely.
- 5:24But then you see it in the book of Ruth chapter one verse 6.
- 5:27It says the Lord had visited his people by giving them food,
- 5:30ending a famine. OK, so it's about a decisive
- 5:32act. God shows up and the status quo
- 5:35is shattered. For good or for I'll.
- 5:37Exactly. When God pecans, things change,
- 5:41history pivots. So here for Sarah, it's God
- 5:45breaking into the timeline of barrenness to make something
- 5:48happen that absolutely would not and could not happen otherwise.
- 5:51Which is the very definition of monarchistic grace.
- 5:54It is, and we need to pause on that word, Monarchistic.
- 5:57It sounds like something you'd hear in a dusty old lecture
- 5:59hall, but our sources insist it is the absolute heartbeat of
- 6:03this passage. That down for the listener who
- 6:06you know doesn't have a theology degree.
- 6:07It's a compound word. Mono means one.
- 6:10Ergon means work, one worker, one worker in the realm of
- 6:14salvation. Reformed theology teaches that
- 6:17God saves us entirely by himself, without our help.
- 6:21We are, as Ephesians says, dead in our sins, and he makes us
- 6:24alive. That is monarchism, one worker
- 6:27doing all the work. And here in Genesis 21, we're
- 6:30seeing a physical picture of that spiritual truth.
- 6:32A perfect one. The conception of Isaac was 100%
- 6:36the work of God, one worker. So Abraham and Sarah didn't like
- 6:41co-author this miracle with God? What?
- 6:43Could they have possibly contributed?
- 6:44The sources are clear on this. They contributed nothing but the
- 6:47problem. They contributed the barrenness.
- 6:49They contributed the old age. They contributed the deadness.
- 6:52God contributed all of the life. It was entirely independent of
- 6:55human merit or capability. Entirely, and the text just
- 6:58hammers this point home with a repetition that you almost trip
- 7:01over when you read it. First one says God visited Sarah
- 7:05as he had said, and then in the very same breath it says the
- 7:09Lord did to Sarah as he had spoken.
- 7:12It feels redundant, doesn't it? Why say it twice, as he said as
- 7:15he spoke? What's the point?
- 7:16The. Point is that we are thick
- 7:18headed. We are so prone to explain away
- 7:21God's work. The source material calls this
- 7:24repetition a Thunder clap of fidelity.
- 7:27It's like a lawyer in a courtroom closing every possible
- 7:30loophole in a contract. So the narrator is worried we
- 7:33might misinterpret this. He's terrified that we might
- 7:36read this story and think, Oh well, maybe Sarah just had a
- 7:38really healthy month. Or maybe the stars aligned, or
- 7:42it was a one in a million biological fluke.
- 7:44We do that, don't we? We get a blessing, a check in
- 7:47the mail we weren't expecting, a medical scan that comes back
- 7:49clear, and our first instinct is often to call it luck or
- 7:53coincidence. We attribute the specific,
- 7:56intentional works of God to the random chaos of the universe.
- 8:00But this text functions like a legal document.
- 8:02Like courtroom testimony, it is tying the event, the conception,
- 8:07directly and exclusively to the promise.
- 8:09It's saying do not dare call this luck.
- 8:11Do not call a chance. This is the performance of God's
- 8:13specific spoken word. Exactly.
- 8:15It completely shifts the focus from Abraham's feelings or
- 8:18Sarah's biology to God's character.
- 8:20And that is a huge shift for most of us.
- 8:23But we usually judge God's faithfulness by how we feel,
- 8:26right? If I feel good, if things are
- 8:27going my way, then God is faithful.
- 8:30If I feel anxious, if my prayers aren't answered on my schedule,
- 8:33then I start to wonder if God has forgotten me.
- 8:35My. Feelings become the measure of
- 8:37God's reality. Yes, but the text says God's
- 8:40faithfulness is grounded in his own nature, not in our emotional
- 8:44state. Numbers 23.19.
- 8:47God is not a man that he should lie if he speaks.
- 8:51His word is performative. It isn't just a description of
- 8:54reality, it contains the power to create that reality.
- 8:58That's a great image. His word isn't just a label for
- 9:01a thing, it's the motor that makes the thing happen.
- 9:03It is the motor. But here's the rub.
- 9:05The motor doesn't always start the second we turn the key.
- 9:07And this brings us right to Section 2, the theology of
- 9:10timing. This is where it gets really
- 9:12uncomfortable for modern people. Verse 2 says Sarah conceived and
- 9:15bore a son to Abraham in his old age at the time of which God had
- 9:19spoken. The sources all highlight this
- 9:21phrase, the appointed time. The Hebrew word is mode, right?
- 9:25Mode, yes, and that word is so significant.
- 9:28Mode means a fixed appointment, a set aside season.
- 9:33It's a date that has been circled on a calendar from the
- 9:36beginning. Which stands in such stark
- 9:37contrast to how we live. I mean, we live in the cult of
- 9:40the immediate, the idol of immediacy, as you said.
- 9:42Completely. If I ordered a package on
- 9:44Amazon, I want it tomorrow, you know I want it this afternoon.
- 9:47If I pray for healing, I want it before Sunday service.
- 9:51We view any kind of delay as a malfunction.
- 9:53That's a perfect way to put it. If the Wi-Fi is slow, we assume
- 9:57the router is broken. If God is slow by our
- 10:00estimation, we assume he is absent or uncaring.
- 10:03But the text directly challenges that assumption.
- 10:06It connects us, as the sources point out, to the Westminster
- 10:09Confession of Faith Chapter 3, which for our listeners is the
- 10:13chapter on God's eternal decree. And it states that God from all
- 10:16eternity did freely and unchangeably ordain whatsoever
- 10:20comes to pass. And whatsoever comes to pass
- 10:22includes the timeline. It includes the specific 2nd
- 10:26that the sperm met the egg in Sarah's 90 year old womb.
- 10:29That was not a random event, it was a divine appointment.
- 10:32Now the sources get a little spicy here.
- 10:36They bring up a theological viewpoint called Open Theism.
- 10:40For the sake of the listener who hasn't been in a late night
- 10:42Twitter debate about this recently, can you explain what
- 10:45that is and why our sources are so keen to pick a fight with it?
- 10:49It's a very relevant fight. I think open theism is a view
- 10:52that suggests the future is to some degree and not fully
- 10:55settled even for God. It posits that God is
- 10:58brilliantly resourceful and is reacting to human choices in
- 11:02real time. He's like a master chess player,
- 11:05but he doesn't know for certain what move you'll make until you
- 11:08actually make it. I can see the appeal of that
- 11:10idea if I'm suffering or if I'm waiting 25 years like Sarah was.
- 11:14It's almost comforting to think, well, God isn't making me wait
- 11:16on purpose. He's just, you know, dealing
- 11:19with this circumstances as they come.
- 11:21It sort of gets got off the hook for the delay.
- 11:23It absolutely does. It tries to save God's
- 11:25reputation for being nice by sacrificing his sovereignty.
- 11:28It suggests he's just doing his best with a fluid, unpredictable
- 11:32situation. But.
- 11:33Genesis 21 just looks that idea right in the eye and rejects it.
- 11:37Completely. Think about Abraham's life
- 11:39during those 25 years. Did he make choices that
- 11:42complicated things? Oh my goodness yes.
- 11:45He slept with Hagar creating chaos.
- 11:47He lied to kings about Sarah being his sister twice.
- 11:51He literally laughed in God's face at the promise.
- 11:55The man was a mess. He was a total mess.
- 11:57Now if God were simply reacting to Abraham's behavior, the
- 12:01timeline for Isaac's birth would have been constantly shifting.
- 12:05God would have been up in heaven saying, well Abraham really blew
- 12:07it this week with that whole abim like thing so I've got to
- 12:09push the birthday back another two years.
- 12:12The timeline would be dependent on human performance.
- 12:14But the text says it happened at the motor at the appointed time.
- 12:17The date was set in eternity. It was never adjusted based on
- 12:21Abraham's successes or more often, his failures.
- 12:24Wow, that is That's both terrifying and incredibly
- 12:28comforting at the same time. How so?
- 12:30It's terrifying because it means the delay wasn't an accident, it
- 12:33was intentional. But it's comforting for the
- 12:36exact same reason. It means the waiting wasn't
- 12:38meaningless. It means the waiting was on
- 12:40purpose. The 25 years in that waiting
- 12:42room were not empty time. They were not wasted years of
- 12:46divine negligence. They were part of the plan.
- 12:49So what was the point? I mean really, why make a 90
- 12:52year old woman, 100 year old man wait that long?
- 12:54From a human standpoint, it feels cruel.
- 12:56It does feel cruel to the flesh, yeah, but the sources argue it
- 13:00was absolutely necessary for the soul.
- 13:02The delay served several key purposes.
- 13:05First, it had to humble human strength.
- 13:07Get rid of any self-reliance. Completely Second, it served to
- 13:10expose their unbelief, their laughter, their Hagar scheme.
- 13:15All of that had to come to the surface.
- 13:17And most importantly, it ensured that when the answer finally
- 13:20came the glory, all of it went solely to God.
- 13:24One of the essays we looked at use this phrase The Corridor of
- 13:27Waiting, and I really like that. It implies that the time between
- 13:30the promise and the fulfillment isn't a dead end, it's a hallway
- 13:33you have to walk down to get ready for the destination.
- 13:35That's exactly it. If Isaac had been born in year
- 13:381, when Abraham was 76, he would have spent the rest of his life
- 13:41saying, look what I did. I'm still virile.
- 13:43He would have taken at least partial credit.
- 13:45By year 25, Abraham knew beyond a shadow of a doubt that he
- 13:48couldn't do anything. The waiting stripped him of his
- 13:51self-reliance. It was a divine sandpaper,
- 13:55smoothing away his pride. It forced him to trade his
- 13:59confidence in his own biology for confidence in God's
- 14:02fidelity. And Speaking of biology, we need
- 14:05to get clinical for a second here.
- 14:07This moves us right into Section 3, which is all about human
- 14:11impossibility and this concept of deadness.
- 14:15Right, let's look at the numbers in verse 5.
- 14:17I said Abraham was 100 years old when his son Isaac was born to
- 14:20him. Now we read the Bible and we can
- 14:23just gloss over ages like that. We think, oh, people live longer
- 14:25back then, whatever. But the narrator is dropping
- 14:28this number on us like a theological bomb.
- 14:30It's not just a fun fact for the birth announcement.
- 14:32No, it's a profound statement of total, absolute human inability.
- 14:37The source material points us directly to the New Testament
- 14:40commentary on this event in Romans chapter 4, verse 19.
- 14:43Where Paul is analyzing this exact moment.
- 14:46Yes, and Paul, under the inspiration of the Holy Spirit,
- 14:49says that Abraham considered his own body as good as dead, and he
- 14:54also considered the deadness of Sarah's womb.
- 14:57Deadness. That is such a brutal final
- 14:59word. It's not weakness, it's not
- 15:02struggling with fertility. It is the absence of life.
- 15:05It's biological finality. It's a closed door, bolted and
- 15:09locked. And that's precisely why Sarah
- 15:11asks that rhetorical question in verse 7.
- 15:13She's holding her baby and she says who would have said to
- 15:16Abraham that Sarah would nurse children?
- 15:17And the implied answer is nobody.
- 15:20Absolutely nobody. No doctor, no midwife, no
- 15:23betting man in Canaan would have put a single shekel on this.
- 15:27From every human perspective, the odds were zero.
- 15:29It was impossible. And this brings us right back to
- 15:32that contrast you mentioned earlier between monarchism, the
- 15:34one worker, and synergism, which is the idea of working together,
- 15:38cooperation. Right.
- 15:39We already saw the synergistic plan back in Genesis 16.
- 15:42That was the Ishmael plan. That was Abraham and Sarah
- 15:44saying OK God promised a son but clearly he needs our help to
- 15:50pull this off. We need to Co labor with God.
- 15:52Let's use our human ingenuity. Let's use Hagar.
- 15:56That was human scheming. That was the energy of the flesh
- 15:58trying to produce a spiritual promise.
- 16:00And it worked technically. I mean, a child was born.
- 16:03A child was born, yes, but it was not the child of the promise
- 16:06and it produced jealousy, conflict and pain that tore the
- 16:10family apart for generations. Isaac is different.
- 16:13Isaac is the anti synergism argument.
- 16:15He's the monarchistic miracle. He represents divine power
- 16:19acting on dead matter. It's creation ex nihilo out of
- 16:22nothing all over again. The sources mention the analogy
- 16:25of faith here. That's a fancy way of saying we
- 16:28use the rest of the Bible to help us interpret this specific
- 16:30passage. So how does this life from death
- 16:33theme connect to the bigger picture of salvation?
- 16:35It's a direct parallel. The birth of Isaac is life from
- 16:38the dead, and that is a perfect picture of what happens when a
- 16:41person becomes a Christian. So we are the dead womb.
- 16:44We are the dead womb in our natural state.
- 16:46We are as spiritually dead as Sarah's womb was physically
- 16:49dead. Just as April one couldn't will
- 16:52his 100 year old body to be young and fertile again, we
- 16:55cannot will ourselves into spiritual life.
- 16:58We can't decide to be born again any more than a corpse can
- 17:01decide to get up and walk. So salvation is extra nose.
- 17:04Yes, that's the Latin phrase the reformers loved.
- 17:07Extra nose from outside of us. It comes from God, not from our
- 17:11own potential or effort. And that is such a severe
- 17:14critique of the modern world, isn't it?
- 17:15We idolize biological autonomy. We think we can control life and
- 17:19death with our technology, our planning, our biohacking.
- 17:22We think we are the masters of our fate.
- 17:24Genesis 21 just laughs at that kind of hubris.
- 17:27It says life, real life, is a gift.
- 17:30It's a gift given to the dead by the God who visits.
- 17:33That is deeply humbling, but it also takes the pressure off in a
- 17:36weird way. I don't have to manufacture my
- 17:38own rescue. You can't.
- 17:39But once the rescue happens, once the life is given, there is
- 17:42a response required. And this moves us to Section 4,
- 17:46the covenant response. And the order here is absolutely
- 17:50critical. We have to get the sequence
- 17:51right or we lose the entire gospel.
- 17:54Verses 1 and 2 are the miracle. Verses 3 and four are the
- 17:57obedience that flows from that miracle.
- 17:59Grace first, then works. Always, every time, If you flip
- 18:03that order, you get legalism. I will obey so that God will
- 18:06give me a son. I'll earn the blessing.
- 18:08Right. And if you disconnect them, you
- 18:10get antinomianism. God gave me a son, so now I can
- 18:13do whatever I want. Obedience doesn't matter.
- 18:15Grace is a free pass. But Abraham models the third
- 18:18way, the biblical way. It's grace.
- 18:21First, obedience. And his obedience is so
- 18:24immediate and precise. Verse 3 says He called the name
- 18:28of his son, whom Sarah bore to him Isaac.
- 18:31Now, naming is typically an act of authority, but here it's
- 18:34actually an act of submission. God had already told Abraham
- 18:37back in chapter 17 to name the boy Isaac Yitzhak.
- 18:40Which means he laughs. He laughs.
- 18:42And that name is just loaded with history for them.
- 18:45Painful history, even. Yeah.
- 18:46The laughter of doubt. Exactly.
- 18:49But by using that specific name, Abraham is publicly submitting
- 18:52to God's definition of reality. He's making a public admission.
- 18:56Yes, we laughed in doubt. Yes, this whole situation is
- 18:59frankly funny. But God has the last laugh, and
- 19:03his laugh is one of joy, not cynicism.
- 19:06He's literally turning a past failure, a moment of weakness,
- 19:10into a present confession of faith.
- 19:12Every single day for the rest of his life.
- 19:14Every time he yelled for his kid to come to dinner.
- 19:16Isaac. Isaac Music.
- 19:18He was preaching A sermon to his entire household.
- 19:21Laughter. Laughter is in my house because
- 19:23of God. The home itself was speaking
- 19:25theology every single day. Then we get to verse 4.
- 19:29Abraham circumcised his son Isaac when he was eight days
- 19:31old, as God had commanded him. And this is where we need to
- 19:34slow down and really look at what the source material is
- 19:36saying, because there's a nuance here that is very easy to miss,
- 19:39especially in our theological circles.
- 19:41Right, because usually in Reformed circles when we talk
- 19:43about Old Testament circumcision, we tend to draw a
- 19:46very straight, Direct Line to New Testament infant baptism.
- 19:50That's the standard covenantal argument.
- 19:52The logic is Isaac was an infant in the covenant family.
- 19:55He received the covenant sign. Our children are infants in the
- 19:58covenant family, so they should receive the new covenant sign,
- 20:02which is baptism. Simple enough.
- 20:03It is, but one of the essays we reviewed actually pushes back on
- 20:08that simple one to one equation. It argues against just swapping
- 20:13out circumcision for baptism to justify the practice without
- 20:16adding some important caveats. OK.
- 20:18Why? What's the objection?
- 20:19The objection centers on a passage in Colossians chapter 2,
- 20:23verses 11 and 12. In that passage, the Apostle
- 20:26Paul talks about a circumcision made without hands.
- 20:29He's referring to regeneration, the spiritual heart surgery, the
- 20:32cutting away of the sinful nature by the Holy Spirit.
- 20:35So Paul is spiritualizing the concept of circumcision.
- 20:38He's showing its ultimate meaning.
- 20:40He's showing the fulfilment of the concept, yes, and the source
- 20:43argues that the physical sign of circumcision in the Old
- 20:46Testament was always pointing forward to this greater
- 20:48spiritual reality in the New Testament.
- 20:51The danger, then, is thinking that the physical sign creates
- 20:54the spiritual reality. Meaning just because an infant
- 20:57is baptized doesn't automatically mean they are
- 20:59regenerated. Just because a Hebrew boy was
- 21:02circumcised didn't guarantee he had a circumcised heart.
- 21:05Precisely. The sign testifies to the
- 21:07promise. It is a seal of God's covenant
- 21:10promises, but it does not magically create saving face in
- 21:13the child. The source just wants to make
- 21:16sure we don't fall into a kind of ritualistic mechanical trap
- 21:20where we think the water, or in Abraham's case, the knife, does
- 21:23the actual saving work. So it's a necessary warning
- 21:26against an ex opera operato view of the sacraments.
- 21:29It is, but, and this is the absolute key for understanding
- 21:32Abraham's response here, the command was still binding.
- 21:35Abraham didn't sit there and say, well, since this physical
- 21:38act is just a sign pointing to a future spiritual reality of
- 21:41regeneration, I think I'll skip the painful part for my son.
- 21:44He didn't debate the theology of it, he simply obeyed the command
- 21:47he was given. Exactly.
- 21:49The recipient of grace responds. He brings his life and his
- 21:53household under God's prescribed sign and rule.
- 21:56So whether you land as a Baptist or Presbyterian on the issue of
- 21:59baptism, the underlying principle here is the same God's
- 22:03grace makes us obedient, not sloppy or disobedient.
- 22:07That's a great point. OK, let's move to Section 5,
- 22:09which is honestly my favorite part of this whole text, the
- 22:13laughter. We've talked about the name
- 22:14Isaac, but the theme of laughter, the Hebrew word sock,
- 22:16is just all over this family. Story.
- 22:18It's a complete roller coaster of laughter.
- 22:20You trace it through Genesis in chapter 17.
- 22:23Abraham hears he'll have a son at 99 and he falls on his face
- 22:26and he laughs. It was a laugh of, you know,
- 22:28shock and probably some disbelief.
- 22:30Are you serious? Then in chapter 18, Sarah is
- 22:34inside the tent. She overhears the same promise,
- 22:36and she laughs to herself. And that was a laughter of pure
- 22:39cynicism. It was that bitter, dry chuckle
- 22:42you give when someone suggests something that you know is
- 22:44impossible. Yeah, right.
- 22:46Me have a baby at 90. I've left that laugh before, the
- 22:49laugh of despair. We all have but now in chapter
- 22:5321 verse 6 Sarah holds Isaac and she says God has made laughter
- 22:57for me. The word is the same, Zahac, but
- 23:01the frequency, the whole emotional tone has changed
- 23:04completely. God has redeemed the laughter.
- 23:07He took the very area of their greatest weakness, their doubt,
- 23:11their cynicism, their mockery even, And he didn't punish them
- 23:15for it. That is the amazing card to me.
- 23:17He didn't strike Sarah mute like he did to Zechariah in the New
- 23:21Testament for a similar kind of doubt.
- 23:23No, he answered the skepticism with a reality so overwhelming
- 23:27and joyful that the skepticism was just washed away.
- 23:30He didn't rebuke their doubt with a lightning bolt, He
- 23:32rebuked it with a baby. He overwhelmed their unbelief
- 23:36with his faithfulness. And Sarah's confession is so
- 23:38personal. God has made laughter for me.
- 23:40She owns it. She acknowledges that God is the
- 23:43sole architect of this joy. And she doesn't keep it private.
- 23:45That's the next part. Right, she says.
- 23:47Everyone who hears will laugh over me or some translation say
- 23:50laugh with me. This is this is laughter as
- 23:52evangelism. It's public testimony.
- 23:54She is inviting the entire community to look at her, a 90
- 23:58year old woman nursing an infant, and see it as undeniable
- 24:01proof of God's power and faithfulness.
- 24:04She's saying, look at this impossible situation and laugh
- 24:08with me at the goodness of a God who does impossible things.
- 24:12The sources contrast this so well with the laughter of fools
- 24:15that's mentioned in Ecclesiastes.
- 24:17This isn't the empty crackling of thorns under a pot.
- 24:20It's not frivolous. No, this is deep, resonant joy.
- 24:24It is the laughter that comes only when the impossible comes
- 24:26true. It is the joy of salvation that
- 24:29conquers the despair of a fallen age.
- 24:31It's the kind of joy that should characterize the church.
- 24:34When the world looks at us, they should see a people who possess
- 24:36a joy that just doesn't make sense on paper.
- 24:38Just like Isaac didn't make sense on.
- 24:40Paper No. Of course we can't do a Reformed
- 24:42deep dive on an Old Testament passage without connecting it to
- 24:45Jesus. So section 6 Christological
- 24:48connections. How is Isaac a type of Christ?
- 24:52Well, if you stop the story at Isaac, you've missed the entire
- 24:55point of the Old Testament. Isaac is a shower, Jesus is the
- 24:59substance, and the parallels are stunning.
- 25:02Both are children of promise. Not of natural human effort, no.
- 25:06Both were born of what you could call a dead or impossible womb.
- 25:09Sarah's womb was dead because of old age, and Mary's womb was
- 25:13dead to conception because she was a virgin.
- 25:16In both cases the birth required a direct supernatural divine
- 25:20miracle, and both arrived at the appointed time.
- 25:23We saw the made for Isaac, Galatians 4 verse 4 says.
- 25:27But when the fullness of time had come, God sent forth his
- 25:30Son, another divine appointment. The gospel logic, then, is
- 25:34identical. Just as Abraham contributed
- 25:36absolutely nothing to Isaac's physical birth, the Sinner
- 25:39contributes absolutely nothing to their spiritual birth.
- 25:42We bring the sin and the death. God brings the life and the
- 25:45grace. But there is a contrast to a
- 25:47heartbreaking one really. A.
- 25:48Later in Genesis chapter 22, Isaac is carried up Mount Moriah
- 25:52by his father to be sacrificed. The ultimate test of Abraham's
- 25:56faith. And at the very last second, God
- 25:59intervenes. He spares Isaac.
- 26:02He provides a ram caught in the thicket to die in his place.
- 26:05But for the true son. For the greater Isaac, for Jesus
- 26:08on that same mountain range, he was not spared.
- 26:10There was no ram in the thicket for Jesus, because he was the
- 26:13ram. He was the substitute.
- 26:15The source material argues that if God kept his word regarding
- 26:19the type regarding Isaac, he will certainly keep his word
- 26:22regarding the antitype Christ and his church.
- 26:24It's an argument from the lesser to the greater.
- 26:27If God can bring biological life out of a geriatric womb, how
- 26:31much more can he bring eternal life out of a sealed tomb?
- 26:34The resurrection of Jesus is the ultimate laughter of God against
- 26:38the impossible finality of death.
- 26:40OK, this brings us to the So what portion of our discussion,
- 26:43Section 7 Law and Gospel application.
- 26:47How does this ancient story land on us today?
- 26:49You know, as we're sitting in our, our cars are doing the
- 26:51dishes. Well, first we have to let it
- 26:53function as the mirror of the law.
- 26:55The text has to expose our own sins in our own waiting rooms.
- 26:59And I think I can name a few of those in my own life.
- 27:01Impatience is the obvious one. Impatience, Yes, but let's dig a
- 27:05little deeper. The story exposes our tendency
- 27:08to manufacture our own solutions.
- 27:10That's the Hagar shortcut. Right when God is silent, we get
- 27:14busy. We try to manipulate outcomes to
- 27:16get what we think we need. We compromise our ethics to get
- 27:19the promotion because we don't trust God to provide it in His
- 27:22time. We try to force doors open that
- 27:25He is clearly locked. We send the text message we know
- 27:27we shouldn't send. And what about cynicism?
- 27:29That's a big one for me. We dress it up as realism.
- 27:32That's so true. We say, oh, I'm just being
- 27:34realistic. God probably won't do that.
- 27:36But really it's just doubt. Wearing a sophisticated tuxedo.
- 27:39We're judging God's fidelity by our own clock, by our own sense
- 27:43of what's possible. And the text says that is a
- 27:46fundamental error. So that's the law hitting us,
- 27:48showing us we're all bad waiters.
- 27:50So where's the comfort of the gospel in this?
- 27:52The gospel comfort is that God's speciality is visiting the dead.
- 27:55He doesn't come to the strong incapable.
- 27:57He comes to the barren and the hopeless, and the promise relies
- 28:00entirely on the promissor, not on the receiver's stamina.
- 28:04That is a massive relief. It is.
- 28:06Abraham and Sarah did not hold on perfectly for 25 years.
- 28:10They wobbled. They doubted.
- 28:12They laughed in cynicism. They schemed, but the good news
- 28:16is that God held on to them. So my faith doesn't have to be
- 28:19ironclad and perfect for God to be faithful.
- 28:21Not at all. His faithfulness holds our
- 28:23wavering faith. And this leads to the third use
- 28:26of the law, the law as a guide for the believer.
- 28:29What do we do while we wait? We don't just sit there
- 28:31passively. We practice active waiting.
- 28:34Active, waiting. It means doing the next right
- 28:36thing in front of you. Abraham obeyed immediately when
- 28:39the time finally came. But in the meantime, what do we
- 28:42do? We use the means of grace God
- 28:44has given us. We pray even when it feels like
- 28:47we're talking to the ceiling. We worship with God's people.
- 28:50We serve our neighbor. We turn our own personal
- 28:52experience of mercy into communal encouragement.
- 28:55We share the laughter. We don't let the waiting room
- 28:57turn us into bitter old Saints. We let God's eventual
- 29:00faithfulness make us into joyful witnesses.
- 29:03We have to testify that the waiting room is not a tomb, it's
- 29:06a womb. It is the place where God is
- 29:09forming something new. That's a beautiful way to put
- 29:11it. That feels like a really good
- 29:13place to land this. We've gone from Baroness to
- 29:16visitation, from skeptical laughter to the laughter of pure
- 29:20doxology. And the core truth holding it
- 29:23all together is that God's Word is performative.
- 29:26What He speaks, He does. It will come to pass.
- 29:29So here is our final thought for you, the listener.
- 29:32You might be in that waiting room right now.
- 29:35The medical report hasn't changed.
- 29:37The job hasn't materialized. The prodigal child is still
- 29:40gone. The ache in your heart is still
- 29:42there. This text challenges you to stop
- 29:45looking at the deadness of your situation, the statistics, the
- 29:48odds, the number of years that have passed.
- 29:50And start looking at the veracity, the truthfulness, the
- 29:53unshakable character of the One who made the promise.
- 29:56So the question is this, if God can bring life from a dead womb,
- 30:00what impossible situation in your life are you wrongly
- 30:03assuming is too hard for Him? That's the question to sit with
- 30:06this week. Thank you for diving deep with
- 30:08us today. This has been reformed thinking.
