Genesis 12:3 → Genesis 3:15

The Abrahamic promise is the decisive narrowing of the Genesis 3:15 seed. "All the families of the earth will be blessed through you" (Gen 12:3) — and, in the immediately following verse, "I will give this land to your offspring (זֶרַע, zera, Gen 12:7)" — locate the woman's serpent-crushing seed in the line of one chosen man. The "blessing/cursing" structure of Genesis 12:3 ("I will bless those who bless you and curse those who curse you") also picks up the enmity-installation of Eden: as in Genesis 3:15, humanity is divided by its stance toward the seed of promise. What was announced over the serpent in the garden is now attached to a covenant family through whom the global reversal of the curse will come. The promise that the nations will be blessed in Abraham's seed is the positive counterpart to the promise that the serpent's head will be crushed: the same coming One both destroys the enemy and restores the blessing forfeited at the Fall. Paul reads this seed as singular and identifies it as Christ (Gal 3:16). The telos is the breadth of the gospel hope: the Eden promise was never parochial — its end is all the families of the earth blessed in the Seed who undoes the serpent's ruin, a salvation worth the world's longing.
