Romans 4:9, 11, 13, 22

Is this blessing then only for the circumcised, or also for the uncircumcised? For we say that faith was counted to Abraham as righteousness.

He received the sign of circumcision as a seal of the righteousness that he had by faith while he was still uncircumcised. The purpose was to make him the father of all who believe without being circumcised, so that righteousness would be counted to them as well

For the promise to Abraham and his offspring that he would be heir of the world did not come through the law but through the righteousness of faith.

That is why his faith was “counted to him as righteousness.”
