God’s Covenant: A Story of Amazing Grace

Vocabulary you already own

If you were catechized in a Lutheran or Reformed congregation, “covenant theology” is not a new framework this session is importing — it is very likely the framework you were taught to read the whole Bible through in the first place. Reformed covenant theology speaks of the covenant of grace running from Genesis 3 through Christ; Lutheran teaching, while more cautious about building an entire covenantal system, still confesses that God’s promises to Israel and his promise in Christ are one continuous, gracious act of God toward an undeserving people. This session simply puts the ancient Near Eastern furniture back into the room so you can see how strikingly that grace was displayed at Sinai and even earlier — and how directly it sets up everything Revelation later assumes about God’s relationship to his people.

How ancient covenants actually worked

In the ancient world, belonging to a family meant survival — provision, protection, identity. If you weren’t born into the right family, Scripture recognizes four doors in: marriage, birth, adoption, and covenant. Historically there were two kinds of covenants. One was between equals — a mutual alliance, its members called brothers. The other was between the strong and the weak: a covenant of conquest, in which the stronger party was called master or father, and the weaker one slave or son. This second type matters most for understanding Israel’s relationship to God, because it was the standard pattern whenever one nation conquered another. The stronger nation held authority; the weaker nation paid tribute — but the stronger nation was in turn obligated to defend the weaker one, because the weaker party was now, in effect, family. Joshua’s covenant with the deceptive Gibeonites (Joshua 9–10) shows exactly this dynamic in practice: once the covenant existed, Joshua was bound to defend them even though he didn’t want to.

The phrase “to make a covenant” literally means “to cut a covenant” — language drawn from the ceremony itself. Animals were cut in half and laid 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 covenant with Abraham — and the reversal

Genesis 15 follows this same ancient pattern of sacrifice and implied threat — with one staggering difference. It is not Abraham, the weaker party, who walks between the divided animals. It is God himself, appearing as fire, who passes between the pieces. God takes Abraham’s place under the covenant curse before Abraham has even broken a single term. That is why, later, when Abraham does break the covenant — his impregnation of Hagar being the clearest instance — it is ultimately God’s own Son who bears the curse instead of Abraham’s son. This is the “amazing grace” of the covenant: God binds himself to a curse he did not deserve, on behalf of a partner who could not keep the terms, long before Calvary makes that arrangement visible in history.

The covenant with Israel — a standard treaty, upended

Ancient conquest covenants followed a standard five-part form: a preamble naming the greater party in grand terms; a prologue recounting the greater party’s past kindness, to encourage willing acceptance; the demands themselves; blessings for obedience and curses for disobedience; and witnesses called to guarantee the covenant would be kept. This exact structure appears in the covenant at Sinai. The preamble: “I am the LORD your God.” The prologue: “who brought you out of Egypt, out of the land of slavery” — look at what I’ve already done for you. The demands begin with the first commandment: have no other gods. Blessings and curses follow in Deuteronomy 28, escalating gradually through Leviticus 26’s repeated “if you still do not listen” — each stage designed to give Israel another chance to reconsider. The witnesses called were heaven and earth themselves (Deuteronomy 30:19).

Crucially — and this is the heart of what makes this a covenant of grace rather than mere law — the covenant’s terms were never impossible, unlike so many earthly treaties designed to set the weaker party up to fail. Israel could have kept the covenant. It chose not to. And through it all, God calls himself Israel’s Father — a father who, even while bound by covenant terms, remains merciful. Scripture captures that combination in the rich Hebrew word hesed, usually translated “covenant loyalty” or “steadfast love” — a word broad enough to mean love, goodness, mercy, and faithfulness all at once, depending on context.

Why this matters for reading Revelation

Once you see the covenant structure clearly, Revelation’s logic becomes far less mysterious. The letters to the seven churches follow exactly this covenant pattern: commendation (prologue — recounting the church’s own faithfulness), demand (repent, hold fast), and blessing-or-curse (a promise to the one who overcomes, a warning to the one who does not). The plagues that follow are not random cruelty; they are the covenant curses of Leviticus 26 and Deuteronomy 28 escalating exactly as they did for Israel — measured, repeated, giving space for repentance at every stage, precisely because that is how the God of the covenant has always dealt with his people. And the whole book culminates in a marriage — the covenant’s oldest metaphor for God’s bond with his people — where the Bride is finally, fully home with the Lamb who bore the covenant curse for her.

Amazing grace, indeed

This is the story confessional Christians sing every time they sing “Amazing Grace,” and confess every time they recite that Christ bore what we deserved. Revelation is not a detour from that story into some separate genre of speculative future-telling. It is that same covenant story reaching its climax — grace that took the curse upon itself at Calvary, applied now to a people who, like Israel, cannot claim to have earned it.

Questions for reflection or discussion

• How does seeing the ancient covenant ceremony of Genesis 15 — God alone walking between the pieces — change how you read the doctrine of Christ bearing our curse?
• Where in the letters to the seven churches (Revelation 2–3) do you see the classic covenant pattern of prologue, demand, and blessing/curse at work?
• Hesed — steadfast covenant love — is hard to translate in one English word. Where have you experienced it, and where do you find it hardest to extend to others?
• If Israel’s covenant terms were genuinely keepable and Israel simply chose not to keep them, what does that say about the nature of sin — and about the necessity of grace?
