¹⁷ Here 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. ¹⁸ God had said to Abraham, ‘It is through Isaac that your family will continue.’ ¹⁹ But 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.^[a]
