⁸ It was by faith that Abraham obeyed when God called him to leave home and go to another land that God would give him as his inheritance. He went without knowing where he was going.

¹¹ It was by faith that even Sarah was able to have a child, though she was barren and was too old. She believed^[a] that God would keep his promise. ¹² And so a whole nation came from this one man who was as good as dead—a nation with so many people that, like the stars in the sky and the sand on the seashore, there is no way to count them.

¹⁷ It was by faith that Abraham offered Isaac as a sacrifice when God was testing him. Abraham, who had received God’s promises, was ready to sacrifice his only son, Isaac, ¹⁸ even though God had told him, “Isaac is the son through whom your descendants will be counted.”^{[a] 19} Abraham reasoned that if Isaac died, God was able to bring him back to life again. And in a sense, Abraham did receive his son back from the dead.
