Genesis 15 explained: God Binds Himself to a Promise

Abram's honest complaint (vv. 1-3)

After his battle and his refusal of the king of Sodom's reward in the previous chapter, God tells Abram not to fear, because God himself will protect and reward him. Abram answers bluntly that no reward means much while he has no child, since by the custom of the time his chief servant Eliezer would inherit everything.

Count the stars (vv. 4-6)

God promises a son from Abram's own body and descendants as countless as the stars, and Abram trusts him. God counts that trust as putting Abram in the right with him, a verse Christians later read, following Paul, as showing that people are accepted by God through trust rather than by earning it.

The animals cut in half (vv. 7-11)

When Abram asks how he can be sure about the land, God has him split animals and lay the halves in two rows. In the ancient Near East, people making a binding agreement could walk between such pieces, in effect calling the same fate down on themselves if they broke their word.

Darkness and a hard future (vv. 12-16)

In a frightening darkness, God says Abram's descendants will live as foreigners, enslaved and mistreated for 400 years, then go free with great wealth, which the Bible later tells as the story of slavery in Egypt and the escape from it. Their return is put off until the wrongdoing of the Amorites, people then living in the land, has run its full course, so the text presents the later taking of the land as judgment on them, a claim many readers find troubling.

God walks the path alone (vv. 17-21)

A smoking firepot and a blazing torch, commonly understood as signs of God's presence, pass between the pieces while Abram does not, so God alone takes the oath on himself. The land is described from Egypt's border to the Euphrates, and the list of nations shows it was already home to many peoples.

Key verse: Genesis 15:6

Where Christians differ

Christians differ on what verse 6 means for how a person is made right with God: some read it as trust alone, while others, also drawing on James's use of Abram, hold that genuine trust and faithful action cannot be separated in that process.

Something to think about

When something you deeply hope for keeps not happening, what helps you decide whether to keep hoping or to let it go?
