Romans 4:11-12

11Some time after that, God told Abraham that someone should circumcise him. That would be a mark on his body to show that God had accepted him. God had already accepted Abraham because Abraham believed in him. God did not accept Abraham because they had circumcised him as a Jewish man. This shows that Abraham is like a father to everyone that God has accepted. Like Abraham, God has accepted them because they have believed in him. It is not important that nobody has circumcised them.

12But Abraham is also like the father of all Jews who believe in God. Someone has circumcised those Jews, but they have copied Abraham's example. They have believed in God, as Abraham believed before anyone had circumcised him.
