He was circumcised as a sign of the covenant God had made with him. It showed that his faith had made him right with God before he was circumcised. So Abraham is the father of all believers who have not been circumcised. God accepts their faith. So their faith makes them right with him.
But things are different with God. He makes ungodly people right with himself. If people trust in him, their faith is accepted even though they do not work. Their faith makes them right with God.
Is that blessing only for those who are circumcised? Or is it also for those who are not circumcised? We have been saying that God accepted Abraham’s faith. So his faith made him right with God.
In Scripture, God says to Pharaoh, “I had a special reason for making you king. I decided to use you to show my power. I wanted my name to become known everywhere on earth.” (Exodus 9:16)
That is what Scripture means where it says, “Abraham believed God. God accepted Abraham because he believed. So his faith made him right with God.” (Genesis 15:6) And that’s not all. God called Abraham his friend.
Don’t you know what Scripture says? God wants the spirit in us to belong only to him. God caused this spirit to live in us. Don’t you think Scripture has a reason for saying this?
