Hebrews 11:17-19

17It 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,

18even though God had told him, “Isaac is the son through whom your descendants will be counted.”

19Abraham 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.
