Romans 2:28-29

2:28 For a person is not a Jew who is one outwardly, nor is circumcision something that is outward in the flesh, 2:29 but someone is a Jew who is one inwardly, and circumcision is of the heart by the Spirit and not by the written code. This person’s praise is not from people but from God.

Romans 4:12-16

4:12 And he is also the father of the circumcised, who are not only circumcised, but who also walk in the footsteps of the faith that our father Abraham possessed when he was still uncircumcised.

4:13 For the promise to Abraham or to his descendants that he would inherit the world was not fulfilled through the law, but through the righteousness that comes by faith. 4:14 For if they become heirs by the law, faith is empty and the promise is nullified. 4:15 For the law brings wrath, because where there is no law there is no transgression either. 4:16 For this reason it is by faith so that it may be by grace, with the result that the promise may be certain to all the descendants – not only to those who are under the law, but also to those who have the faith of Abraham, who is the father of us all
