Background: God's Covenant: A Story of Amazing Grace
Opening Hook
Describe an old-world mob protection racket: a stronger power offers “protection” to a weaker one, in exchange for total loyalty and regular payment — break the deal, and the strong power turns on you. That’s uncomfortably close to how ancient international treaties actually worked, including many of the covenants surrounding Israel’s story. Then ask your group: what if, at the critical moment, the powerful party in a deal like that stepped forward and took the weaker party’s punishment on himself, voluntarily, before any betrayal had even happened? That’s exactly what God does with Abraham in Genesis 15 — and it’s the hinge this whole session turns on.
The Core Teaching
The full argument is in expl/background/israel/gods-covenant.md.
How ancient covenants actually worked. There were two basic kinds of ancient treaty. Covenants between equals functioned like alliances — mutual support, and the members could even be called “brothers.” Covenants of conquest were different: the stronger party was “father” or “master,” the weaker was “son” or “slave” — but crucially, the stronger party was obligated to defend the weaker one, precisely because the weaker party was now, in effect, family. We see this play out concretely when the Gibeonites tricked Joshua into a covenant: once bound, Joshua was later obligated to defend them against the Amorites even though he didn’t like them (Joshua 10:1-14). A weaker party in this kind of covenant couldn’t make other covenants on the side — you can only have one father — and breaking the covenant (usually by refusing tribute) meant losing the land and going into exile.
Original-language note: “cutting” a covenant. The Hebrew phrase for making a covenant literally means “cutting” a covenant — drawn from the sacrificial ritual at the ceremony itself. Animals were cut in half and arranged in two rows, and the weaker party walked between the pieces: a vivid, deliberate act of intimidation showing exactly what would happen to him if he broke his word.
The stunning reversal with Abraham. In Genesis 15, this exact covenant ritual takes place — sacrifices cut in half, arranged in two rows — but with one critical difference. It is not Abraham, the weaker party, who walks between the pieces. It is God Himself, represented by fire, who passes through. God takes on Abraham’s place under the covenant curse before Abraham has even broken anything. So when Abraham later does break the covenant — by fathering a child through Hagar rather than trusting God’s promise — the consequence doesn’t fall on Abraham’s line the way ancient covenant law would demand; ultimately it is God’s own Son who dies in the place the curse pointed to. This is the gospel, quietly embedded in Genesis 15, centuries before Sinai and millennia before the cross.
The Sinai covenant follows the standard ancient treaty format precisely — and seeing that format actually deepens the meaning rather than reducing it to bureaucratic paperwork. Ancient conquest treaties had five standard parts: a self-glorifying preamble naming the ruler, a prologue recounting the ruler’s past kindness (meant to invite willing loyalty, not just compel it), a list of demands, blessings-and-curses for keeping or breaking the terms, and witnesses called to guarantee it. Sinai follows this exactly:
- Preamble: “I am the Lord your God”
- Prologue: “…who brought you out of Egypt, out of the land of slavery” — look at what I’ve already done for you, and trust there’s more to come.
- Demands: beginning with the foundational command to have no other gods (Exodus 20:3-6).
- Blessings and curses: Deuteronomy 28:1-14 and 28:15-68, with an escalating series of warnings in Leviticus 26 — “if you still do not listen, I will…” — each stage designed as an invitation to reconsider, not simply a countdown to punishment.
- Witnesses: heaven and earth themselves.
A detail worth pausing on: the terms were never impossible. Unlike many ancient covenants designed to set the weaker party up for inevitable failure and permanent subjugation, God’s covenant terms were genuinely achievable. Israel could have kept them. They simply, repeatedly, chose not to. That matters for how we read the prophets’ harsh language later: it isn’t the disproportionate anger of an impossible-to-please deity, but the real grief of a covenant partner who kept His own side completely and asked for nothing His people couldn’t actually do.
Original-language note: hesed. Through all of this, God calls Himself the Father of Israel (Exodus 3:6) — a father who, even while legally entitled to enforce covenant curses, remains merciful. Scripture captures that combination in the Hebrew word hesed (חֶסֶד), usually translated “covenant loyalty” or “steadfast love,” but rich enough to also carry the sense of goodness, mercy, and faithfulness depending on context. It’s one of the most theologically loaded words in the Old Testament — not sentimental affection, but committed, active loyalty that keeps showing up even when the covenant partner hasn’t earned it.
Discussion Questions
Understanding the text:
- Walk through the five-part ancient covenant structure (preamble, prologue, demands, blessings/ curses, witnesses) and match each part to its location in Exodus 20 and Deuteronomy 28. What surprises you about how tightly Sinai follows this pattern?
- Why does it matter that God, not Abraham, walked between the pieces in Genesis 15? What would the story mean if it had gone the other way?
- What does the escalating “if you still do not listen” pattern in Leviticus 26 tell us about God’s purpose in warning His people before judgment actually lands?
So what for us: 4. Hesed means committed loyalty that keeps showing up even when it isn’t earned. Where have you experienced that kind of loyalty from God recently — and where might you need to extend it to someone else this week? 5. The covenant terms were never impossible — Israel could have kept them but didn’t. Where in your own life do you quietly tell yourself that faithfulness is “too hard,” when the real issue is that you haven’t chosen it? 6. God took on the covenant curse Himself, before any betrayal occurred. How does picturing that scene in Genesis 15 change how you understand what happened at the cross?
Closing Prayer Prompt
Thank God specifically for His hesed — His committed, covenant loyalty that has kept showing up in your life even in seasons you didn’t deserve it. Ask Him to help your group trust that His covenant demands, however weighty they feel, are never impossible — and to renew your willingness to actually keep them, not just admire them from a distance.
