Romans 4:9-12

Now, think about it. Does this happiness come only to the Jews, or is it available to all who believe? Our answer is this: faith was credited to Abraham as God’s righteousness! How did he receive this gift of righteousness? Was he circumcised at the time God accepted him, or was he still uncircumcised? Clearly, he was an uncircumcised gentile when God said this of him! It was later that he received the external sign of circumcision as a seal to confirm that God had already transferred his righteousness to him by faith, while he was still uncircumcised. So now this qualifies him to become the father of all who believe among the non-Jewish people. And like their “father of faith,” Abraham, God also transfers his righteousness to them by faith. Yes, Abraham is obviously the true father of faith for the Jewish people who are not only circumcised but who walk in the way of faith that our father Abraham displayed before his circumcision.
