Romans 2:28-29
From Wesleyan Discipline
2:28 A person is not a Jew who is one only outwardly, nor is circumcision merely outward and physical. 2:29 No, a person is a Jew who is one inwardly; and circumcision is circumcision of the heart, by the Spirit, not by the written code. Such a person’s praise is not from other people, but from God.
