²¹ Don’t you remember that our ancestor Abraham was shown to be right with God by his actions when he offered his son Isaac on the altar?

¹⁶ “This is what the Lord says: Because you have obeyed me and have not withheld even your son, your only son, I swear by my own name that ¹⁷ I will certainly bless you. I will multiply your descendants^[a] beyond number, like the stars in the sky and the sand on the seashore. Your descendants will conquer the cities of their enemies. ¹⁸ And through your descendants all the nations of the earth will be blessed—all because you have obeyed me.”

⁹ When they arrived at the place where God had told him to go, Abraham built an altar and arranged the wood on it. Then he tied his son, Isaac, and laid him on the altar on top of the wood. ¹⁰ And Abraham picked up the knife to kill his son as a sacrifice. ¹¹ At that moment the angel of the Lord called to him from heaven, “Abraham! Abraham!”

“Yes,” Abraham replied. “Here I am!”

¹² “Don’t lay a hand on the boy!” the angel said. “Do not hurt him in any way, for now I know that you truly fear God. You have not withheld from me even your son, your only son.”

³⁹ “Our father is Abraham!” they declared.

“No,” Jesus replied, “for if you were really the children of Abraham, you would follow his example.^[a]

³⁷ The words you say will either acquit you or condemn you.”
