Background: God's Covenant: A Story of Amazing Grace
Family is everything
In the ancient world, belonging to a family meant survival itself — provision, protection, identity, everything. Belonging to a strong, respected family meant even more. Many of us here understand that instinctively; the extended family and clan still shape daily life across much of our continent in ways many Western readers have to have explained to them.
But what if you weren’t born into the right family? Scripture recognizes four doors into a family: birth, marriage, adoption — and covenant. Today we look at the last one, because it’s the one that explains the whole story running underneath the book of Revelation.
How ancient covenants worked
In the ancient world, there were two kinds of alliances. One was between equals — mutual support, and the members could be called “brothers.” The other was between the strong and the weak — a covenant of conquest, where the stronger party was called “father” or “master,” and the weaker one “son” or “servant.”
This second kind matters most for understanding Israel’s relationship with God. When a strong nation conquered a weaker one, the stronger party ruled over it — but was also obligated to defend it, because the weaker party was now, in effect, family. We see this exact dynamic when the Gibeonites tricked Joshua into a covenant with them (Joshua 9): once the covenant existed, Joshua was bound to defend them, even against enemies he’d rather have let deal with them (Joshua 10:1-14).
Making such a covenant was called, literally, “cutting a covenant” — from the sacrifice performed at the ceremony. Animals were cut in half and laid out in two rows, and the weaker party walked between the pieces. The message was blunt: this is what happens to you if you break your word.
God flips the pattern
In Genesis 15, God makes exactly this kind of covenant with Abraham — the sacrifice, cut in half, arranged in two lines. But here’s the astonishing detail: it is not Abraham, the weaker party, who walks between the pieces. It is God himself, in the form of fire, who passes through. God takes on himself the curse that should fall on the one who breaks the covenant.
So later, when Abraham does break covenant — fathering Ishmael through Hagar instead of trusting God’s promise — it is not Abraham’s son who bears the curse. It is God’s own Son who eventually does, at the cross.
The covenant at Sinai
Ancient conquest covenants followed a standard five-part pattern: a preamble naming the ruler’s greatness, a prologue recounting kindness already shown, a list of demands, blessings for obedience and curses for disobedience, and witnesses called to guarantee it.
This exact pattern appears at Sinai. The preamble: “I am the LORD your God” (Exodus 20:2). The prologue follows immediately: “who brought you out of Egypt, out of the land of slavery” — look at all I have already done for you. The demands begin with the foundational one: have no other gods before me (Exodus 20:3-6), from which the rest of the Ten Commandments flow. The blessings and curses appear in Deuteronomy 28. And the witnesses called are heaven and earth themselves (Deuteronomy 30:19).
Crucially: the terms of God’s covenant were never impossible to keep, unlike so many human covenants designed to set the weaker party up for failure. Israel could have kept the covenant. They simply chose not to.
Through it all, God calls himself Israel’s Father (Exodus 3:6) — a Father who, even while bound by covenant terms, remains merciful. Scripture has a word for that combination: hesed, usually translated “covenant loyalty” or “steadfast love” — rich enough to mean love, goodness, mercy, and faithfulness all at once.
Why this matters for reading Revelation
Revelation is often read as a book of threats and disasters. But underneath every warning is this covenant logic: a Father who bound himself to his people by an oath sealed in his own blood, long before they ever proved themselves worthy of it. The letters to the seven churches, the plagues, the call to endurance — none of it makes sense outside this covenant framework. God is not a distant judge looking for an excuse to punish. He is a Father who has already paid the covenant curse himself, in Jesus, and who now calls his covenant family to remain faithful in return — not to earn his love, but because it has already been so lavishly given.
A word about family and covenant here
For many of us, family, clan, and lineage carry enormous weight — who your father was, what your family is known for, who will vouch for you. That instinct is not wrong; Scripture takes family seriously too. But Revelation’s covenant logic pushes even further: through Christ, we have been brought into God’s own family, sealed by a covenant no human family bond can rival — one that cost God everything and costs us nothing but our loyalty in return. Whatever family we were born into, we now belong, first, to this one.
Questions to carry with you
Where do you still feel you have to “earn” your way into God’s family, rather than trusting that Christ already paid the price? What would it look like to treat your covenant with God with the same seriousness your culture already gives to family bonds and obligations? Who around you needs to hear that God’s covenant faithfulness — his hesed — does not depend on their worthiness, only on his promise?
