12 And Abraham is also the father of those who have been circumcised. But it is not their circumcision that makes him their father. He is their father only if they live following the faith that our father Abraham had before he was circumcised.
13 Abraham and his descendants received the promise that they would get the whole world. But Abraham did not receive that promise because he followed the law. He received that promise because he was right with God through his faith.
14 If people could get God’s promise by following the law, then faith is worthless. And God’s promise to Abraham is worthless,
15 because the law can only bring God’s anger on those who disobey it. But if there is no law, then there is nothing to disobey.
16 So people get what God promised by having faith. This happens so that the promise can be a free gift. And if the promise is a free gift, then all of Abraham’s people will get that promise. The promise is not just for those who live under the Law of Moses. It is for all who live with faith as Abraham did. He is the father of us all.
17 As the Scriptures say, “I have made you a father of many nations.” This is true before God, the one Abraham believed—the God who gives life to the dead and speaks of things that don’t yet exist as if they are real.
18 There was no hope that Abraham would have children, but Abraham believed God and continued to hope. And that is why he became the father of many nations. As God told him, “You will have many descendants.”
