Romans 2:26-29
2:26 Therefore if the uncircumcised man obeys the righteous requirements of the law, will not his uncircumcision be regarded as circumcision?
2:27 And will not the physically uncircumcised man who keeps the law judge you who, despite the written code and circumcision, transgress the law?
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.
