Hebrews 11:17-19

17Here is another example of Abraham's faith. God wanted to see whether Abraham really trusted him. Because Abraham believed God, he offered his son, Isaac, as a sacrifice. God had promised Abraham that he would have many grandchildren. But Abraham was still ready to offer his only son as a sacrifice.

18God had said to Abraham, ‘It is through Isaac that your family will continue.’

19But Abraham was sure that, if Isaac died, God could raise Isaac to life again. We could even say that is a picture of what really happened. It was like Abraham did receive Isaac back from death.
