12. Abraham is also the father of the circumcised who believe. So just being circumcised is not enough. Those who are circumcised must also follow the steps of our father Abraham. He had faith before he was circumcised.
13. Abraham and his family received a promise. God promised that Abraham would receive the world. It would not come to him because he obeyed the law. It would come because of his faith, which made him right with God.
14. Do those who obey the law receive the promise? If they do, faith would have no value. God's promise would be worthless.
