Romans 4:16-17

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. 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.
