Abraham Cycle
Genesis 12–25:11
The call, covenant cut, covenant signed, covenant tested — the Abrahamic foundation.
From Genesis 12 the pace slows. One man, one family, one promise. The call of Abram (12:1–3) is the hinge of the entire book and arguably of the entire Old Testament: Get thee out of thy country… and I will make of thee a great nation… and in thee shall all families of the earth be blessed. The Abrahamic covenant comes in three movements: chapter 12 (call and promise), chapter 15 (covenant cut between divided animals, the smoking furnace and burning lamp), and chapter 17 (covenant sign of circumcision). Chapter 22, the binding of Isaac, is the covenant tested and the typological apex of the cycle.
The NT will read this cycle as the foundational text on faith. Romans 4 stakes its argument on Abraham's faith reckoned as righteousness in Genesis 15:6, before circumcision (4:10), before the law (4:13). Galatians 3 stakes the gospel itself on the seed-promise to Abraham (Gal 3:16). Hebrews 11 quotes Genesis 22 to ground its theology of resurrection-faith.
Key movements
12:1–9, The call
Get thee out. The first sevenfold promise. Abraham's age (75) and obedience.
15, Covenant cut
Faith reckoned for righteousness (15:6). The smoking furnace and burning lamp pass between the pieces.
17, Covenant sign
Name change to Abraham. Circumcision as covenant sign and seal. Sarah named.
22, Covenant tested
Take now thy son, thine only son. Mount Moriah. The substituted ram. Jehovah-jireh. The typological apex of the cycle.

Christ in this section
Christ is the seed promised to Abraham (Gal 3:16) and the substituted Lamb of Mount Moriah (Gen 22). Both are typological: the cycle anticipates Calvary at every covenant moment.
