Romans 2:27-29

New Century Version

²⁷ You Jews have the written law and circumcision, but you break the law. So those who are not circumcised in their bodies, but still obey the law, will show that you are guilty. ²⁸ They can do this because a person is not a true Jew if he is only a Jew in his physical body; true circumcision is not only on the outside of the body. ²⁹ A person is a Jew only if he is a Jew inside; true circumcision is done in the heart by the Spirit, not by the written law. Such a person gets praise from God rather than from people.
