Romans 4:9-12

9 Is this blessing then only for 1the circumcised, or also for the uncircumcised? 2We say that faith was counted to Abraham as righteousness.
10 How then was it counted to him? Was it before or after he had been circumcised? It was not after, but before he was circumcised.
11 3He received the sign of circumcision as a seal of the righteousness that he had by faith while he was still uncircumcised. The purpose was 4to make him the father of all who believe without being circumcised, so that righteousness would be counted to them as well,
12 and to make him the father of the circumcised who are not merely circumcised but who also walk in the footsteps of the faith that our father Abraham had before he was circumcised.
