Romans 4:10-20 NIV

10 Under what circumstances was it credited? Was it after he was circumcised, or before? It was not after, but before!
11 And he received the sign of circumcision, a seal of the righteousness that he had by faith while he was still uncircumcised.1 So then, he is the father2 of all who believe3 but have not been circumcised, in order that righteousness might be credited to them.
