The Smoking Oven and the Burning Torch: God's Unconditional Oath and the Certainty of the Covenant (Genesis 15:17–21) · Reformed Thinking

• 0:00
  Welcome to Reform Thinking. Today we're doing a deep dive
• 0:03
  into a passage that, well, it's one of the most foundational and
• 0:07
  let's be honest, one of the strangest moments in the whole
• 0:09
  book of Genesis. We're looking at chapter 15.
• 0:12
  It's an absolute hinge point if you've ever asked that question.
• 0:16
  How can I be sure? How can I really know?
• 0:18
  I'm saved? This chapter is the anchor.
• 0:21
  Absolutely. Our focus is on that mysterious
• 0:23
  ceremony, the one where God makes his covenant with Abram
• 0:27
  official. We want to take this wild,
• 0:29
  dramatic vision and figure out what it tells us about the
• 0:33
  ground of our hope. And that hope is an oath.
• 0:35
  An oath sworn by God himself. And, well, a pretty terrifying
• 0:39
  darkness. Right, we're going to see that
• 0:41
  Christian certainty isn't built on how tightly we can hold on to
• 0:44
  God. No, not at all.
• 0:45
  It's about how fiercely God holds on to his own promises.
• 0:48
  It all comes down to a smoking oven, a flaming torch and some
• 0:52
  some severed animals. So to really get the power of
• 0:54
  what God does here, we have to understand just how desperate
• 0:57
  Abram's situation is when Genesis 15 opens you.
• 1:00
  Have to remember we are years, maybe decades past the initial
• 1:05
  call back. In Genesis 12, Abram did what
• 1:07
  God said. He left everything.
• 1:09
  He traveled to this foreign land.
• 1:10
  And what does he have to show for it?
• 1:12
  Not much. I mean, God promised him a great
• 1:15
  nation, descendants as numerous as the stars and this specific
• 1:18
  piece of land. But the reality on the ground
• 1:20
  is, well, it's the complete opposite.
• 1:22
  He's old. Sarah is barren, he has no heir.
• 1:26
  He's basically a wealthy nomad living in a tent.
• 1:29
  Exactly. He's got this incredible divine
• 1:31
  promise, but zero visible evidence that it's coming true.
• 1:35
  And you see him trying to solve the problem himself, right?
• 1:37
  He suggests his servant Eliserva Damascus could be his heir.
• 1:40
  He's trying to make it work. He's trying to bridge the gap
• 1:42
  between God's Word and his own reality.
• 1:45
  And that tension just boils over in verse 8.
• 1:48
  God has just told him again, you will inherit this land.
• 1:51
  And Abram just asked point blank, O Lord God, how am I to
• 1:54
  know that I shall possess it? And it's so easy for us to read
• 1:57
  that as you know, a moment of weak faith, maybe even a demand
• 2:01
  for a sign. But that's not what it is.
• 2:03
  It's crucial we don't misread this.
• 2:05
  This isn't rebellion. This is the cry of a frail
• 2:07
  faith. He's not saying I don't believe
• 2:09
  you. He's saying I believe you, but
• 2:11
  everything I can see with my own eyes is screaming that you're
• 2:14
  wrong. Help me.
• 2:15
  Yes. Give me something objective,
• 2:17
  something I can hold on to when the doubts start creeping in.
• 2:21
  He wants assurance. He has the promise.
• 2:23
  Now he's asking for the seal on the contract.
• 2:26
  And God's response is just, it's beautiful.
• 2:29
  There's no rebuke. There's no Haven't I said
• 2:31
  enough? No, it's sheer condescension,
• 2:33
  God Stoops down. He accommodates Abraham's
• 2:36
  weakness by giving him something tangible, something outside of
• 2:39
  Abrams own feelings or willpower.
• 2:41
  So God tells him to prepare this really specific sacrifice.
• 2:44
  He needs to get a three-year old heifer, a three-year old goat, a
• 2:47
  ram, a turtle dove and a pigeon. Right.
• 2:50
  And the preparation itself is just grueling.
• 2:52
  These are prime animals. Abram has to slaughter them, cut
• 2:55
  them in hat except for the birds, and arrange the pieces
• 2:58
  opposite each other. Creating this this path between
• 3:01
  the bloody halves. A corridor of death, really.
• 3:04
  It's gruesome work. And after all that effort, what
• 3:07
  happens? He just waits, the text says.
• 3:10
  He spends the day standing guard.
• 3:11
  And waiting for what? Well, the smell of death brings
• 3:15
  Scavengers, birds of prey, vultures.
• 3:18
  It's such a powerful picture. Abram spends his energy his
• 3:21
  entire day fighting off these vultures of doubt that are
• 3:25
  trying to consume the sacrifice, consume his hope.
• 3:28
  That's it exactly. He's doing everything he can.
• 3:29
  He's striving, he's working. He's keeping the sacrifice pure.
• 3:33
  The human effort has a limit. Eventually you just run out of
• 3:36
  strength. And right at that point, when
• 3:38
  Abram can't do anything more, that's when the supernatural
• 3:41
  kicks in. The sun goes down.
• 3:43
  But this isn't just evening. No, the text calls it a horror
• 3:46
  of great darkness. The Hebrew word here, alatah,
• 3:50
  suggests a thick, terrifying gloom.
• 3:53
  It's the kind of darkness you see at Mount Sinai when God
• 3:55
  descends. It signals that something holy
• 3:57
  and dreadful is about to happen. And just before that darkness
• 4:00
  hits, a deep sleep falls on Abram A Tartama.
• 4:04
  We need to pause on that word. We do.
• 4:06
  This isn't a normal nap, this is a divinely induced stupor.
• 4:10
  It's the exact same word used for the deep sleep that fell on
• 4:13
  Adam when God created Eve from his side.
• 4:16
  So it means a complete shutdown of human agency.
• 4:19
  He's incapacitated, paralyzed really, by the dread of God's
• 4:23
  presence. And this is the absolute key to
• 4:26
  the whole chapter. Abram is made utterly passive.
• 4:29
  He's not a negotiator here, he's a spectator, A helpless 1.
• 4:32
  Yes, God is stripping him of any and all self-reliance.
• 4:37
  It's like God is saying your work is done.
• 4:39
  You fought the vultures, you prepare the animals.
• 4:41
  Now the real work, the work that actually seals this deal, is
• 4:44
  mine, and mine alone. Which sets up the context of
• 4:47
  these ancient treaties perfectly.
• 4:49
  The Suzarin vassal treaty. How would that ceremony normally
• 4:52
  have gone down? Well, in that kind of covenant
• 4:54
  cutting ritual, the parties, or at least the lesser party, the
• 4:58
  vassal, would walk between those severed animal pieces.
• 5:00
  And what was the point of that walk?
• 5:02
  It was a self meledictory oath. You were essentially saying if I
• 5:05
  break this covenant, may I be torn apart just like these
• 5:07
  animals. It was a walk of death.
• 5:09
  OK, so if this was a covenant based on Abrams performance, a
• 5:12
  covenant of works? Then Abraham should be the one
• 5:14
  walking. He should be awake, alert and
• 5:17
  pledging his total obedience as he walks through that bloody
• 5:20
  corridor. But he's not.
• 5:21
  He's unconscious, asleep in a supernatural darkness.
• 5:24
  He can't walk. He can't promise anything.
• 5:26
  He can't do a thing, and his inability is precisely the stage
• 5:30
  God needs. It has to be a monarchistic
• 5:33
  work, A work of one God alone has to take on the whole burden.
• 5:36
  And then, into that silent, terrifying darkness, something
• 5:41
  happens. The text says Hyena.
• 5:44
  Behold. It's an intrusion, sudden,
• 5:47
  dramatic, and what appears is this paradox, a smoking firepot
• 5:52
  and a flaming torch. This is a theophany, right?
• 5:54
  A visible manifestation of the invisible God?
• 5:57
  That's right. And the two symbols are so
• 5:59
  specific. First you have the smoking
• 6:00
  firepot, the Tanner. Portable oven or furnace.
• 6:03
  Yeah, I think intense, consuming heat.
• 6:05
  The smoke immediately connects you to the smoke at Sinai.
• 6:08
  It's a symbol of God's consuming holiness and his judgement
• 6:11
  against sin. This is the fire of Wrath.
• 6:13
  But right alongside it you have the flaming torch, the lapid
• 6:15
  which. Is the opposite.
• 6:16
  It's a piercing light, its guidance, illumination, grace
• 6:21
  the torch promises life and direction.
• 6:23
  So you have judgement and mercy, the oven and the torch moving
• 6:26
  together. Acting in perfect concert, Yeah.
• 6:28
  And they're moving through that bloody cord or that path that
• 6:32
  represents the curse for breaking the covenant.
• 6:34
  We know from other places, like Jeremiah 34, that this symbolism
• 6:38
  was absolutely concrete. If you broke the oath, you'd end
• 6:41
  up like the calf. Exactly.
• 6:43
  So here's the theological shock of the whole story.
• 6:45
  Who walks that path? God.
• 6:47
  God alone. The smoking oven and the flaming
• 6:49
  torch. This dual manifest station of
• 6:51
  Yahweh passes between the pieces while Abram is still completely
• 6:55
  unconscious. Just turns everything on its
• 6:57
  head. It does.
• 6:58
  By walking that path alone, God is taking the entire curse, the
• 7:01
  whole self meledictory oath upon himself.
• 7:04
  Yes, he's saying. What is he saying?
• 7:06
  He is swearing. If I failed to keep my promise
• 7:08
  to you, Abram, let me be torn apart.
• 7:10
  Let this curse fall in my head. That's just immense.
• 7:13
  So this isn't a normal contract, it's what theology calls a royal
• 7:16
  grant. Precisely.
• 7:18
  It's a unilateral promise. The obligation rests 100% on the
• 7:23
  1 making the promise. This is why the author of
• 7:26
  Hebrews says that because God could swear by no one greater,
• 7:30
  he swore by himself. So our certainty, our assurance,
• 7:33
  isn't anchored in Abraham's ability to keep his end of the
• 7:36
  deal. Or ours.
• 7:37
  It's anchored in God's oath to God.
• 7:40
  His own character is on the line.
• 7:42
  He's essentially guaranteed 2 things.
• 7:43
  One, the promise will be kept, and two, he will personally pay
• 7:48
  whatever penalty is required when Abrams descendants
• 7:51
  inevitably fail. So for Abram, that path of the
• 7:54
  curse is transformed. It becomes the path of grace,
• 7:57
  the fire of wrath that should consume the covenant Breaker is
• 8:00
  now the very thing that secures the promise for him.
• 8:02
  Which brings us to the cross, because this whole scene leaves
• 8:05
  a huge tension hanging in the air.
• 8:07
  A massive 1. God has sworn an unconditional
• 8:09
  oath, but his people, Israel, are going to be anything but
• 8:13
  faithful. They're going to break the
• 8:14
  covenant over and over again. They deserve the curse.
• 8:16
  So how can God be just and punish sin, but also keep his
• 8:21
  promise to bless them? That is the problem that the
• 8:23
  entire Old Testament wrestles with, and the answer is that God
• 8:27
  finds a way to be both the just judge and the one who justifies
• 8:31
  the ungodly. And this ceremony in Genesis 15
• 8:34
  is a direct prophecy of how he'll do it.
• 8:37
  The cutting of the Covenant. The carrot beareth.
• 8:40
  Points directly to the cutting off of the Messiah.
• 8:43
  Daniel 9 says the Messiah will be cut off, but not for himself.
• 8:47
  It's the same idea. Jesus, the true seed of Abraham,
• 8:50
  came to be the covenant victim. This is why the incarnation is
• 8:52
  so critical. The God who passed between the
• 8:54
  pieces in that vision had to take on human flesh.
• 8:57
  So that he could literally, historically, physically bear
• 9:01
  the curse of that oath. The one who swore the oath
• 9:04
  becomes the victim required by the oath.
• 9:06
  And you see the parallels so clearly, that horror of great
• 9:08
  darkness that fell on Abram. It finds its echo in the three
• 9:11
  hours of darkness that fell over Golgotha.
• 9:14
  That wasn't just a solar eclipse.
• 9:15
  That was the alotta, the divine judgment, darkness descending on
• 9:18
  the sun, the. Smoking oven had arrived.
• 9:20
  It had, and into that darkness the full fire of God's wrath
• 9:24
  against sin was poured out on Christ.
• 9:27
  He became the severed animal. He was torn apart, body and
• 9:30
  soul, so that the oath could be fulfilled and the promise
• 9:33
  secured. Paul says it's so clearly in
• 9:35
  Galatians. Christ redeemed us from the
• 9:37
  curse of the law by becoming a curse for us.
• 9:40
  He stepped into that bloody corridor in our place.
• 9:43
  This is the heart of penal substitutionary atonement.
• 9:46
  The fire consumed the innocent covenant keeper instead of us,
• 9:50
  the guilty covenant Breakers. And because that debt is paid,
• 9:53
  paid by God Himself, the promise to Abraham becomes irrevocable.
• 9:57
  It's guaranteed we are the beneficiaries of a contract we
• 10:00
  couldn't sign. The wrath of the smoking oven
• 10:03
  passed over us because it was fully absorbed by him.
• 10:05
  And now the light of the flaming torch guides us.
• 10:08
  It's just incredible. It is.
• 10:09
  OK, So after that, that mind blowing theological spectacle,
• 10:14
  God's voice cuts through the darkness and gets incredibly
• 10:16
  specific. Yeah, the transition is jarring,
• 10:19
  but it's intentional. He moves from the supernatural
• 10:22
  guarantee to a concrete physical land grant.
• 10:24
  Verse 18 On that day the Lord made a covenant with Abram,
• 10:28
  saying To your offspring, I give this land.
• 10:31
  It's not a vague spiritual feeling.
• 10:33
  It's a dated legal transaction. It's real.
• 10:36
  And it's a gift, it's an inheritance.
• 10:38
  It fits perfectly with the justification by faith we saw
• 10:40
  earlier in the chapter. Abram receives the title deed.
• 10:43
  He doesn't earn it. And the boundaries are laid out
• 10:45
  with I mean surveyor like precision we are.
• 10:49
  From the river of Egypt to the Great river, the river euphates.
• 10:52
  That is a massive amount of land, far more than Israel ever
• 10:56
  controlled even under Solomon. What's the point of defining it
• 10:59
  so so big and so precisely? Well, a couple of things.
• 11:03
  First, it tells you that God is the Lord of actual geography, of
• 11:07
  real space and time. This isn't just pie in the sky
• 11:09
  stuff. But second, the sheer scale of
• 11:11
  it preaches the necessity of divine power.
• 11:14
  There's no way Abram and his descendants could take that on
• 11:16
  their own. God has to do it.
• 11:18
  This brings up a huge point of debate in theology, doesn't it?
• 11:22
  Hermeneutics. A lot of traditions would say
• 11:25
  that this land promise is spiritualized for the church
• 11:28
  today, that it means heaven or spiritual rest.
• 11:32
  It's a very common view, but as reformed thinkers who hold to a
• 11:36
  grammatical, historical reading of Scripture, we have to push
• 11:39
  back on that. Why?
• 11:40
  Why is it so important to insist that when God says Euphrates, he
• 11:45
  means the actual river? Because it's a question of God's
• 11:48
  integrity. When Abram heard that promise,
• 11:51
  what he understand, he understood a literal river, a
• 11:54
  real piece of land. To turn that into a metaphor,
• 11:57
  does violence to the text. But it's more than just a matter
• 11:59
  of interpretation, isn't it? It is.
• 12:01
  It's about the reliability of God's word.
• 12:03
  Look, if God can make an oath sworn in his own blood about a
• 12:06
  specific defined piece of real estate and then just sort of
• 12:09
  change the terms later and say, oh, I meant that metaphorically,
• 12:12
  then on what basis can we trust any of his other specific
• 12:16
  historical promises? Like the bodily resurrection?
• 12:18
  Exactly. Or the physical return of
• 12:20
  Christ. The land promise is a test case
• 12:22
  for the character of God. If He means what he says about
• 12:25
  the dirt, you can be absolutely sure he means what he says about
• 12:28
  your soul. His word is trustworthy.
• 12:31
  And after defining the borders, God then lists the current
• 12:35
  occupants 10 nations. Kenites, Kenizzites, Hittites,
• 12:39
  Amorites, Jebusites, the list goes.
• 12:42
  On this isn't just a random list, it functions like a legal
• 12:44
  document. That's right, it's the legal
• 12:46
  description on the deed. It says here are the current
• 12:49
  tenants whom I, the owner, will be evicting to give this
• 12:51
  property to you. It reinforces the literal nature
• 12:54
  of the grant. And it's also a form of
• 12:56
  assurance, isn't it? In a strange way.
• 12:58
  A powerful form God is saying I know exactly who is in the way.
• 13:02
  I see every obstacle. I have accounted for every
• 13:04
  single enemy before you even know their names.
• 13:07
  So the promise isn't naive. It's not fragile.
• 13:09
  God knows the difficulty ahead. And he's already declared the
• 13:13
  outcome. And it also explains the delay.
• 13:16
  Remember, he told Abram, his descendants would wait 400 years
• 13:19
  because the iniquity of the Amorites is not yet complete.
• 13:23
  Right, so Israel's possession isn't based on their own
• 13:26
  righteousness. Not at all.
• 13:27
  It's based on God's just judgement against those nations.
• 13:31
  When the victory comes, it has to be seen as a gift, not an
• 13:35
  entitlement. So let's bring this all
• 13:37
  together. We've seen this incredible
• 13:38
  drama. Where, then, does our assurance
• 13:41
  really live? It lives where God put it
• 13:44
  outside of us. Assurance is an objective
• 13:46
  anchor, not a subjective feeling.
• 13:49
  We find it by looking outward to God's sworn oath, ratified in
• 13:52
  fire and fulfilled at the cross. So we have to reject that, turn
• 13:56
  inward that temptation to look at our own performance or the
• 13:59
  temperature of our own fear. Introspection is the enemy of
• 14:02
  assurance. It leads to pride one day and
• 14:04
  despair the next. When you feel the vultures of
• 14:07
  doubt circling, you, don't look inside.
• 14:08
  You look back to Genesis 15. You look to the God who swore to
• 14:12
  be torn apart if his promise failed.
• 14:13
  And the order of events in the chapter is so clear.
• 14:16
  First justification by faith in verse 6, then the covenant
• 14:20
  ratification in verse 17. The order is everything.
• 14:23
  It destroys legalism. God commits to Abram, while
• 14:26
  Abram has nothing to offer but faith.
• 14:29
  Obedience, then, becomes the fruit of that secure
• 14:32
  relationship, not the root of it.
• 14:34
  We obey because we're secure, not to become secure.
• 14:37
  Exactly and finally that darkness.
• 14:40
  The covenant was sealed in a horror of great darkness, and
• 14:43
  God promises that the path to fulfilment will include
• 14:46
  affliction and long delays. So our assurance has to be
• 14:49
  strong enough to withstand those dark seasons.
• 14:51
  It does. God guarantees fulfilment, not
• 14:54
  an easy ride. The fire in the darkness teaches
• 14:57
  us that God's faithfulness shines brightest when our
• 14:59
  circumstances look the bleakest. So the message is simply to rest
• 15:03
  in the oath. The fire still burns.
• 15:05
  The darkness can't put it out. What a deep dive.
• 15:08
  We have seen the blazing glory of God's fidelity in the deepest
• 15:11
  darkness of human inability, are standing with Him rest
• 15:15
  completely on the bedrock of His unilateral, unconditional oath.
• 15:18
  An oath that cost him everything.
• 15:20
  The price was paid in full by Christ, so the call for you
• 15:23
  listening now is to stop looking at your own striving feet.
• 15:26
  Stop trying to fight the vultures in your own strength.
• 15:28
  Look to the torch. The contract is signed in the
• 15:30
  blood of the Son of God. Your inheritance is secure.
• 15:34
  Which brings me to a final thought for you to consider.
• 15:36
  Genesis 15 directly connects the salvation of the soul, that
• 15:40
  justification by faith, to the promise of a specific physical
• 15:44
  piece of land, an earthly inheritance.
• 15:48
  So what does that connection tell us?
• 15:50
  What does it mean that God used this ultimate fiery act of self
• 15:54
  commitment to secure a geopolitical reality?
• 15:57
  It tells us that God's plan is not just to evacuate souls from
• 15:59
  a doomed planet. That's not abandoning creation.
• 16:02
  No, He intends to reclaim and redeem the physical world he
• 16:05
  made and called good. The torch that guided Abram
• 16:08
  through the darkness still burns, and it's guiding us
• 16:10
  toward a sure, solid, real inheritance in a renewed
• 16:13
  creation.
