Romans 4:9-13

9Is this blessing only on the circumcised, or also on the uncircumcised? We have been saying that Abraham’s faith was credited to him as righteousness. 10In what context was it credited? Was it after his circumcision, or before? It was not after, but before.1

11And he received the sign of circumcision as a seal of the righteousness that he had by faith while he was still uncircumcised. So then, he is the father of all who believe but are not circumcised, in order that righteousness might be credited to them. 12And he is also the father of the circumcised who not only are circumcised, but who also walk in the footsteps of the faith that our father Abraham had before he was circumcised.

13For the promise to Abraham and his offspring that he would be heir of the world was not given through the law, but through the righteousness that comes by faith.
