“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.
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.””

“If people could get God’s promise by following the law, then faith is worthless.
And God’s promise to Abraham is worthless, 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.
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.”

“So how did this happen? Did God accept Abraham before or after he was circumcised? God accepted him before his circumcision.
Abraham was circumcised later to show that God accepted him. His circumcision was proof that he was right with God through faith before he was circumcised. So Abraham is the father of all those who believe but are not circumcised. They believe and are accepted as people who are right with God.”

“But people cannot do any work that will make them right with God. So they must trust in him. Then he accepts their faith, and that makes them right with him. He is the one who makes even evil people right.”

“If Abraham was made right by the things he did, he had a reason to boast about himself.
But God knew different. That’s why the Scriptures say, “Abraham believed God, and because of this he was accepted as one who is right with God.””

“I mean we are made right with God through faith, not through what we have done to follow the law. This is what we believe.
So do we destroy the law by following the way of faith? Not at all! In fact, faith causes us to be what the law actually wants.”
