Latest / Reformed Thinking / The Hinge of Revelation: Covenant Disclosure, Righteous Judgment, and Abraham’s Call (Genesis 18:16–21)
Transcript
- 0:00Welcome to Reformed Thinking, the deep dive that takes your
- 0:03sources and extracts the crucial insights you need.
- 0:06We're starting this deep dive in a pretty unique place.
- 0:10Not a city, not a library, but under these ancient terebin
- 0:13trees in Mamre. That's right, we've just come
- 0:15from a scene of incredible fellowship.
- 0:17You have simple food, water and this huge promise of a son being
- 0:22renewed to Abraham and Sarah. And then just like that, the
- 0:25whole scene shifts. It's quite dramatic.
- 0:27The men stand up. They do.
- 0:29And it's a really it's a jarring transition.
- 0:31You go instantly from the grace of the covenant meal to, well,
- 0:35the gravity of a divine courtroom.
- 0:37Genesis 18.1 CM says it right there.
- 0:40The men rose from there and look towards Sodom.
- 0:42And it's so much more than just a geographical move.
- 0:44It's a theological pivot. It puts Abraham and it puts us
- 0:48right on the edge of a precipice.
- 0:50OK, so let's set this up because the geography here is
- 0:52everything. You have three figures who we
- 0:54understand to be the preincarnate Christ and two
- 0:56angels, and they're leaving Abraham's tent.
- 0:59They. Start walking toward the heights
- 1:00of Hebron. And that vantage point, that
- 1:03Ridge, yeah, it's a literal dividing line, but it's a moral
- 1:06one, too. Absolutely.
- 1:08Think about it. To the West you have Abraham's
- 1:11home. It's peaceful.
- 1:12It's ordered a place of blessing.
- 1:15And to the east. The ground just drops away into
- 1:18the Jordan Valley and down there is that lush, well watered plain
- 1:22that lot chose. It looked great on the surface.
- 1:25But it wasn't, no. From up on the heights where God
- 1:29and Abraham are standing, you see it for what it is, a a
- 1:33cauldron of rebellion and moral chaos.
- 1:36So that physical height really preaches the spiritual truth.
- 1:39Abraham is up high walking in communion with God, getting this
- 1:42revelation. And meanwhile, down below, Sodom
- 1:45has no idea. They're just living their lives,
- 1:47totally oblivious to the judgement that's literally
- 1:49gathering on the Ridge above them.
- 1:50It's the picture of the elect versus the world, isn't it?
- 1:53Yeah, one group walks with God and knows his plans, and the
- 1:56other is just eating and drinking until the fire falls.
- 1:59It is the ultimate antithesis. And this is where the story just
- 2:02becomes incredible. The creator of the universe, the
- 2:05one on a mission to execute judgement, he just pauses,
- 2:07Stops. He stops his whole procession to
- 2:10do what? To talk to a nomad, a creature
- 2:14of dust. And that's the central question
- 2:16for our deep dive right there. Why?
- 2:18Why does the Creator share His sovereign plans with this man?
- 2:22That's our mission, to stand on that Ridge with Abraham and
- 2:25listen in on this conversation between the friend of God and
- 2:29the judge of all the earth. We want to pull out the specific
- 2:32points God is making about covenant, about justice, and,
- 2:36you know, the whole purpose of election.
- 2:38And the text gives us the answer.
- 2:39It's because God made a covenant that turns a servant into a
- 2:43friend. He doesn't hide things from
- 2:45those that he brings into that kind of relationship.
- 2:48The whole marvel here is the disclosure itself.
- 2:50OK, let's look closer to verse 16 then.
- 2:52And Abraham's posture. He doesn't just say goodbye at
- 2:55the tent door, the text says. He walks with them.
- 2:58And that's so much more than just being a polite host, right?
- 3:00The Hebrew verb there is halak. It means to walk, sure, But in
- 3:04Genesis, when it's talking about someone's relationship with God,
- 3:07it means something way deeper. Like with Enoch, Enoch walked
- 3:11with God. Exactly.
- 3:12It's this lingering fellowship, a habitual communion.
- 3:16You get the sense Abraham is just savory.
- 3:18Bring every last second of this visit.
- 3:21He doesn't want it to end. And this intentional walk, this
- 3:24halach, it immediately sets up this stark contrast with his
- 3:27nephew Lot A. Tragic figure.
- 3:30While Abraham is up on the heights walking with God, where
- 3:34do we find Lot later? Sitting in the gate of Sodom,
- 3:37he's not just living there, he's absorbed by the culture, the
- 3:40very culture that's about to be destroyed.
- 3:42So there's a principle here for us, isn't there?
- 3:44A huge 1. You can't know the mind of God
- 3:46if you're not walking in his presence.
- 3:48The secrets of heaven aren't just, you know, shouted from the
- 3:51rooftops for everyone. They're whispered to those who
- 3:53walk with him. Right.
- 3:54To those who cultivate that constant halaq, that disciplined
- 3:57daily walk distance from God means ignorance of His will.
- 4:01It's that simple. And that shared walk leads us
- 4:04right into the incredible rhetorical question in verse 17.
- 4:08The Lord stops. The King of the Universe pauses
- 4:11his March. To consult with a man, he says.
- 4:14Shall I hide from Abraham what I'm doing?
- 4:16We have to just sit with that for a second.
- 4:18The divine condescension there is almost unbelievable.
- 4:21This is not God being indecisive.
- 4:23He's not asking for Abraham's opinion.
- 4:25Like hey, what do you think I should do?
- 4:27No, of course not. He's omniscient.
- 4:29It's a rhetorical question, and it's designed to reveal the very
- 4:32heart of the covenant he's made. So why ask it?
- 4:35Why voice it out loud if he already knows the answer?
- 4:38Because by asking shall I hide, the Lord is basically making a
- 4:43declaration. He's saying that hiding his
- 4:45plans from his covenant people is.
- 4:49It's inconsistent with his character.
- 4:51It's not who he is. He's bound himself to Abraham by
- 4:53a promise. And that promise elevates
- 4:55Abraham from just being a subject to being a confidant, a
- 4:58friend. And this isn't just a one off
- 5:00thing for Abraham, this idea shows up later in scripture too.
- 5:02Oh, absolutely, the prophet, Amos says.
- 5:04It's so clearly. Surely the Lord God does nothing
- 5:07unless He reveals His secret to His servants, the Prophet.
- 5:10So God is inviting bring him into what?
- 5:12His Judicial council not to get his vote, but.
- 5:15But to let him understand the why, to see the moral necessity
- 5:18of the judgement that's coming. God wants His people to get not
- 5:23just what He does, but why he does it, so they can see His
- 5:26righteousness in it. He's treating him like a friend
- 5:30who's in on the masters business, not a servant who just
- 5:33gets orders. That's a perfect way to put it.
- 5:35Think about a King's court. The servants wait outside for
- 5:37orders. The King's friends are inside in
- 5:40the strategy sessions. And God is about to do something
- 5:42so terrifying it's going to be a warning for all of history.
- 5:45And he's not going to do it without a witness on Earth who
- 5:48gets it. Someone who can explain the
- 5:50justice of the ACT to the generations that will follow.
- 5:53So the disclosure isn't just for Abraham's benefit.
- 5:56It's vocational. It's equipping him to teach his
- 5:59family. Precisely which, you know,
- 6:01forces us to put in a really important theological safeguard
- 6:04here. We have to be careful how we
- 6:06apply this today. You mean people using this to
- 6:09justify like private prophecies or new revelations?
- 6:12Exactly modern mysticism. In Abraham's day, the Bible
- 6:16wasn't complete. God spoke directly in these
- 6:18physical appearances. That was necessary then.
- 6:21But not now. But not now.
- 6:23In our time, God has fully and finally revealed His mind in the
- 6:27completed Word of God. We believe in the sufficiency of
- 6:30Scripture. So the secret of the Lord is now
- 6:33an open book. It's the Bible.
- 6:35That's it. To walk with God today is to be
- 6:38immersed in His Word, not to be waiting for some extra biblical
- 6:42whisper. The Spirit illuminates the text
- 6:46we already have. That's a critical distinction.
- 6:48It keeps everything anchored to the objective truth of
- 6:51Scripture, not our subjective feelings.
- 6:54And this whole scene, this Old Testament interaction, it's
- 6:58pointing forward, isn't it? It's pointing to Christ.
- 7:00It absolutely is. You can draw a straight line
- 7:02from this moment to the upper room.
- 7:04Which Jesus said to the disciples, yes.
- 7:07No longer do I call you servants, but I've called you
- 7:09friends. For all that I have heard from
- 7:11my father, I've made known to you.
- 7:12That's the culmination. Abraham is the prototype.
- 7:15And because we're united to Christ by faith, we're brought
- 7:19into that same inner serval of divine counsel.
- 7:22We know how history ends. God hasn't hidden his plan from
- 7:25us. Wow, if the Lord stopped his
- 7:28March to judgment for Abraham his friend.
- 7:31How much more certain is the disclosure of the Father's plan
- 7:34to us who are united to the Son? It's a staggering thought.
- 7:38It really frames how we should read all of scripture.
- 7:41So let's move from that relational privilege to its
- 7:43actual foundation. The Lord continues in verse 18
- 7:46by anchoring all of this in His promise.
- 7:49Yes, he says, since Abraham shall surely become a great and
- 7:53mighty nation, and all the nations of the earth shall be
- 7:55blessed in him. And that phrase shall surely
- 7:58become. There's a real finality to it.
- 8:00Oh, it's absolute certainty. The Hebrew construction there
- 8:03implies it's a done deal. This isn't based on Abraham's
- 8:06performance. It's a decree based on God's
- 8:08ability and his faithfulness. And this promise, we need to be
- 8:12careful to see its dual fulfillment, right?
- 8:14Yes, very careful. There's a literal national
- 8:17fulfillment in Israel. The go got the Dal or great
- 8:20nation. And then there's the spiritual
- 8:22blessing that extends to all nations, to the Gentiles through
- 8:25Christ. And it's important to keep those
- 8:27two distinct. It is because if God can just,
- 8:30you know, arbitrarily cancel His promise to national Israel, then
- 8:34what kind of assurance do we have about His promise to the
- 8:36church? God's faithfulness is the
- 8:39bedrock of our salvation. So the reason God is sharing His
- 8:42plan is because Abraham is the chosen vessel for this
- 8:46unstoppable world blessing promise.
- 8:49The stability of the future rests on God's promise, not on
- 8:52the patriarch's performance. And that leads us straight to
- 8:54verse 19, to the core reason for the choice.
- 8:58For I have known him. This is the golden chain of
- 9:01election. We really need to dig into that
- 9:03Hebrew verb yada. Which means to know.
- 9:05It means to know, but not just in a cognitive way, like knowing
- 9:08facts about someone in the Bible, Yada often means this
- 9:12intimate, covenantal choosing love.
- 9:15It's deeply personal. When God says I have known Him,
- 9:19He's saying I have set my unique, electing love upon Him.
- 9:22It's the same language God uses for Israel later in Amos.
- 9:25You only have I known of all the families of the earth.
- 9:28Exactly. He didn't just know about the
- 9:30Egyptians, he knew Israel in this special covenantal way.
- 9:33And this reading of Yada is why this passage is such a
- 9:36stronghold for doctrine of unconditional election.
- 9:38It completely flips the script on the idea that God chose
- 9:42Abraham because he looked into the future and saw that Abraham
- 9:45would have faith. It refutes that entirely.
- 9:48Abraham was an idolater in ur when God called him.
- 9:50God knew him, set his affection on him before Abraham did a
- 9:54single good thing. Abraham's faith is the result of
- 9:57God's choice, not the cause of it.
- 9:59It's all of grace. All of grace based on nothing in
- 10:02Abraham, but only only on God's good pleasure.
- 10:05But look at where the text goes immediately.
- 10:07I have known him in order that he may command his children.
- 10:10So there's the logic. Election is never just a status,
- 10:13it's for a purpose. It's always unto holiness and
- 10:16obedience. God chooses you so that you will
- 10:18live a certain way. This is the biblical answer to
- 10:21the charge of antinomianism. The idea that if you're chosen,
- 10:24you can just live however you want.
- 10:25Right. The Scripture says the evidence
- 10:27of being known by God is that you start intentionally ordering
- 10:32your life and your household according to God's ways.
- 10:35The purpose of election is intensely practical.
- 10:38And that purpose is specified to command his children and his
- 10:43household after him. That word command, What's up?
- 10:46That's a strong word. It's authoritative.
- 10:47It's the language of general use.
- 10:49It's not a suggestion. So spiritual leadership in the
- 10:52home isn't passive. It's supposed to be intentional,
- 10:54instructional. The Father is responsible for
- 10:57the spiritual direction of the family.
- 11:00And this deliberate training is God's ordinary way of advancing
- 11:03the covenant through the generations.
- 11:05Now the source material brings up how this verse gets used in
- 11:08the baptism debate because it's all about instruction and
- 11:11response. It does, and we should touch on
- 11:12that carefully. The core of the verse is
- 11:15Abraham's duty to instruct his household so that they keep the
- 11:18way of the Lord. The reality of the covenant is
- 11:20passed on through that faithful teaching and the Spirit's work.
- 11:24Which leads to an active response.
- 11:26Right. It leads to repentance, faith,
- 11:29obedience. So how did the different views
- 11:31use this? Well, those who hold to
- 11:34believers baptism would say, look, the central action here is
- 11:37conscious obedience that flows from instruction.
- 11:40So the sign baptism should be applied to those who have been
- 11:43taught and can respond in faith. The reality comes before the
- 11:46sign. In their view, yes, whereas
- 11:49those who practice infant baptism would emphasize that the
- 11:52covenant promise includes the children of believers, and the
- 11:56sign marks them as part of the visible covenant community, with
- 11:59the expectation that this instruction will follow.
- 12:02But the source material seems to focus on the common ground.
- 12:05It does, which is that regardless of your view on the
- 12:08sign, the covenant promise actually moves forward through
- 12:11this faithful word centered discipleship in the home.
- 12:15The command to sava to instruct is non negotiable for everyone.
- 12:19OK, So what is the content of that command?
- 12:21What is the way of the Lord? The text defines it right there
- 12:25to do righteousness and justice, said Aku Amishpat.
- 12:28The twin pillars of God's throne.
- 12:30Exactly. Sedeca or righteousness is about
- 12:34our moral uprightness before God.
- 12:36It's our vertical relationship conforming to His standard.
- 12:39And MISHPAT, Justice. That's the horizontal
- 12:43application of that standard to other people.
- 12:45It's protecting the weak, honoring marriage, dealing
- 12:48fairly in business, speaking truth.
- 12:50It's ensuring the standard of Zedeca is applied equitably to
- 12:53everyone. So righteousness and justice are
- 12:56two sides of the same coin. Have one without the other.
- 12:59This two-part command is the precise moral opposite of Sodom,
- 13:03which was defined by both perversion of violation of
- 13:05righteousness and injustice, especially toward the vulnerable
- 13:09and the stranger. The Covenant community, then, is
- 13:11called to be a counterculture. A distinct moral community that
- 13:14practices both not to earn their election, but because they have
- 13:17been elected. It's the fruit.
- 13:19It's the evidence of being truly known by God.
- 13:22And just as we get comfortable with the warmth of that covenant
- 13:24promise, the tone shifts again and it gets cold.
- 13:28Vast it does. The Lord turns his attention
- 13:30from his friend to the cities he must judge.
- 13:33And this brings us to the terrifying revelation in verse
- 13:3520, the outcry. The Lord says because the outcry
- 13:39against Sodom and Gomorrah is great and because their sin is
- 13:42very grave, that word outcry, zaka, he said.
- 13:47It's a sobering word. It's one of the most serious
- 13:49legal terms in the Old Testament.
- 13:51It's not just, you know, noise or general complaint.
- 13:53It's a technical forensic term. It's a formal appeal for
- 13:56justice. It's the Primal Scream of a
- 13:58victim. It's the cry you make to a
- 14:00higher court when the earthly systems of justice have
- 14:04completely failed you. We see it with Israel and Egypt.
- 14:07Yes, they're groaning under slavery was a Zaka, and even
- 14:10before that, the blood of Abel cried out from the ground.
- 14:13It was a Zak demanding justice against Cain.
- 14:15This just demolishes the modern idea of private sin, doesn't it?
- 14:19The idea that what people do is their own business and doesn't
- 14:21affect anyone. Scripture says sin is loud.
- 14:25The moral chaos in Sodom, the perversion, the violence, the
- 14:28assaults on the image of God. It wasn't quiet.
- 14:31It generated a noise so deafening it reached the throne
- 14:34of heaven. And our sources point to Jude 7
- 14:36to specify that sin, sexual immorality, and the pursuit of
- 14:40strange flesh acts contrary to God's created order.
- 14:44And when a society does that, when it abandons God's law, the
- 14:48inevitable result is that injustice flourishes, the
- 14:51innocent suffer, and the moral vacuum creates this sound that
- 14:55demands a response from heaven. It's a chilling thought to
- 14:58consider what kind of zakah our own culture might be sending
- 15:01out. It is the accumulated sins of a
- 15:03nation. They're not silent.
- 15:05So in response to this outcry we get the theological puzzle in
- 15:09verse 21. God says I will go down now and
- 15:12see whether they have done all together according to the
- 15:14outcry, and if not, I will know. And the immediate question is,
- 15:17wait a minute, does the omniscient God need to take a
- 15:21road trip to find out what's going on?
- 15:23Is he unsure of the facts? It's a critical point.
- 15:26If you take that too literally, you could slide into something
- 15:29like Open Theism. Which is the error?
- 15:31That God's knowledge is incomplete, that it grows over
- 15:33time. We reject that completely.
- 15:35Psalm 139 is clear. God knows our thoughts before we
- 15:38think them. So if he's not going down to
- 15:40gather information, what is the point of saying I will go down
- 15:44and see? It's a perfect example of
- 15:46anthropomorphism. God is speaking in human terms
- 15:49to teach us a divine truth about His character as judge.
- 15:53He's acting like a perfect earthly judge would.
- 15:55Exactly. A just judge doesn't sentence
- 15:57someone based on rumors. He investigates, He examines the
- 16:01evidence, he establishes the facts publicly.
- 16:04So it's for the display, the public demonstration of his
- 16:07justice. Right.
- 16:08By saying this God is differentiating himself from all
- 16:11the Pagan gods who were just impulsive and angry.
- 16:13The God of the Bible acts according to strict,
- 16:16unimpeachable justice. When the judgment falls, no one
- 16:19can say it wasn't deserved. The evidence has been presented.
- 16:23And that phrase altogether, according to the outcry, that
- 16:26underlines the proportionality of it all.
- 16:28Yes, and here's here's where it gets terrifying for us.
- 16:31Because that meticulous standard God applies to Sodom, It's the
- 16:35same standard of justice for everyone.
- 16:37If he investigates us with that same rigor.
- 16:39What would He find? If the Holy One goes down to
- 16:42investigate our hearts, our hidden thoughts, to see if we've
- 16:45kept His law perfectly, who could possibly stand?
- 16:48It just destroys any hope of being saved by our own
- 16:51performance. Completely because our own
- 16:54pride, our own lust, our own idolatry, it all creates its own
- 16:58zakah, crying out for justice. The terror of this divine
- 17:02investigation is what shows us how desperately we need a
- 17:05mediator. The law is a terrifying
- 17:08standard, and God takes it with absolute seriousness.
- 17:11He must because he is righteous. And we see Abraham immediately
- 17:15try to step into that role of intercessor.
- 17:18In the next verses. He appeals to God's own
- 17:19character. Shall not the judge of all the
- 17:22earth do? It is just.
- 17:23It's a brilliant prayer. He anchors his appeal in God's
- 17:26own moral perfection. He's teaching us how to pray.
- 17:28But Abraham's intercession, as good as it is, is limited.
- 17:32He can plead, but he can't atone.
- 17:34He can't satisfy justice. He can't remove the guilt.
- 17:37For that, we need someone far greater than Abraham.
- 17:40We need the true mediator, Jesus Christ.
- 17:42The contrast is so stark, God said.
- 17:44I will go down and see the sin. But Christ didn't just go down
- 17:47to investigate our sin. He went down to the cross to be
- 17:50crushed by the penalty of it. He didn't come as an observer.
- 17:52He came as a substitute to absorb the wrath that Arzaka
- 17:56demanded. And in doing that, he silences
- 17:59our outcry of guilt. He does.
- 18:01He silences it with two louder cries.
- 18:04The cry of victory. It is finished.
- 18:06The debt is paid. And the cry of agony.
- 18:08My God, my God, why have you forsaken me?
- 18:11Which shows he took the full condemnation we deserved.
- 18:14The fire that consumed Sodom was, in a spiritual sense,
- 18:17poured out on the sun. He took the fire so we could
- 18:20receive the friendship. The terror of God's perfect
- 18:22justice only makes the grace of the gospel more stunning.
- 18:25The judge was judged in our place.
- 18:28And knowing this, understanding God's character in this way,
- 18:31it's not just theology for our heads, it creates an
- 18:34accountability for how we live. It has to.
- 18:36It defines our responsibility today.
- 18:38If God has shown us His Holiness and His grace, we are now
- 18:41accountable to live in a way that reflects that light.
- 18:44Which brings us right back to our covenant vocation.
- 18:46Creating the anti Sodom community starting in our own
- 18:49homes. God's ordinary plan is the
- 18:51faithful instructed household fathers, mothers.
- 18:54We have to take that command to service seriously.
- 18:56Deliberate word center training, resisting the culture.
- 18:59Because of a home just quietly goes along with what God calls
- 19:02grave fin. It's teaching its children the
- 19:05assumptions of Sodom. And the church as a whole is
- 19:08called to be that anti Sodom community practicing both
- 19:12righteousness and justice. Sedeka Umesh Pat according to
- 19:15God's Word, not the slogans of the age.
- 19:18We can't separate personal holiness from public justice.
- 19:21We can't, and the story of Sodom stands forever as a canonical
- 19:25warning about final judgement. It tells us God's patience is
- 19:28not the same as permissiveness. But it's also a testimony that
- 19:32God knows how to rescue the godly, even an imperfect one.
- 19:35Like Lot, the Gospel is the only refuge from the coming wrath.
- 19:39The knowledge of God's justice drives us to Christ, and the
- 19:42knowledge of Christ's atonement has to drive us to obedience.
- 19:45So we've completed our deep dive.
- 19:47We've moved from the amazing privilege of covenant friendship
- 19:50to the reality of sovereign election, and then to the
- 19:53terrifying standard of God's righteous judgement.
- 19:55We walk in the way of the Lord because we have been elected to
- 19:58holiness. But our hope, our real security,
- 20:01is entirely in our substitute who absorbed that terrifying
- 20:04investigation for us. So here's the final sobering
- 20:07thought for you to take away from this.
- 20:09The terror of Genesis 18.21 is that God is keeping the books,
- 20:15knowing His meticulous standard of investigation and the gravity
- 20:19of the zakah that rises from all sin.
- 20:21What is the only secure ground you can stand on?
- 20:24And the answer can't be our own obedience.
- 20:26It's flawed. The only answer is the perfect
- 20:28obedience and sacrifice of Christ.
- 20:30Our rest is in the fact that the Judge of all the earth did what
- 20:33was just by condemning our sin in the body of His own Son.
- 20:36Go home and fulfill your election by commanding your
- 20:38household in the way of the Lord, being serious about
- 20:41righteousness, and resting completely in the perfect
- 20:43justice that was met in Christ. Yeah.
