Romans 2:25

2:25 For circumcision has its value if you practice the law, but if you break the law, your circumcision has become uncircumcision.

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.
