Romans 4:10-11
Context4:10 How then was it credited to him? Was he circumcised at the time, or not? No, he was not circumcised but uncircumcised! 4:11 And he received the sign of circumcision as a seal of the righteousness that he had by faith while he was still uncircumcised, 1 so that he would become 2 the father of all those who believe but have never been circumcised, 3 that they too could have righteousness credited to them.
