Hebrews 11:17-20

It was by faith that Abraham, when God tested him, offered his son Isaac as a sacrifice. God made the promises to Abraham, but Abraham was ready to offer his own son as a sacrifice. God had said, “The descendants I promised you will be from Isaac.” Abraham believed that God could raise the dead, and really, it was as if Abraham got Isaac back from death. It was by faith that Isaac blessed the future of Jacob and Esau.
