¹¹ Abraham was circumcised as a sign. It was a sign that he was a good man, because he believed when he was not yet circumcised. That makes him the father of all people who believe, even those who are not circumcised. God says they are good people.

¹² That makes him also the father of those who are circumcised. I mean people who are circumcised and do as our father Abraham did. Even when he was not circumcised, he believed.

¹³ God promised Abraham and his family that the world would belong to them. God did not make the promise because Abraham obeyed the law. But he made the promise because Abraham believed him and was put right with God.
