Look at Abraham, your ancestor, and Sarah, who gave birth to your ancestors. Abraham had no children when I called him, but I blessed him and gave him many descendants.
And Abraham is also the father of those who have been circumcised and who live following the faith that our father Abraham had before he was circumcised.
So people receive God’s promise by having faith. This happens so the promise can be a free gift. Then all of Abraham’s children can have that promise. It is not only for those who live under the law of Moses but for anyone who lives with faith like that of Abraham, who is the father of us all.
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.
But I, the Lord, took your ancestor Abraham from the other side of the river and led him through the land of Canaan. And I gave him many children, including his son Isaac.
