Romans 4:9-13

9Is this blessing only for the circumcised, then? Or is it also for the uncircumcised? For we say, Faith was credited to Abraham for righteousness.

10In what way, then, was it credited — while he was circumcised, or uncircumcised? It was not while he was circumcised, but uncircumcised.

11And he received the sign of circumcision as a seal of the righteousness that he had by faith while still uncircumcised. This was to make him the father of all who believe but are not circumcised, so that righteousness may be credited to them also.

12And he became the father of the circumcised, who are not only circumcised but who also follow in the footsteps of the faith our father Abraham had while he was still uncircumcised.

13For the promise to Abraham or to his descendants that he would inherit the world was not through the law, but through the righteousness that comes by faith.
