Romans 2:25-29 - Circumcision Of The Heart
25 For circumcision is indeed a benefit to thee, if thou keep the Law; but if thou art a breaker of the Law, thy circumcision hath become uncircumcision. 26 If then he who is uncircumcised keep the precepts of the Law, shall not he though uncircumcised be regarded as circumcised? 27 Yea, those who are by nature uncircumcised, if they perform the law, will judge thee, who having a written Law and circumcision, art a breaker of the Law. 28 For he is not a Jew, who is one outwardly, nor is that circumcision, which is outward, in the flesh; 29 but he is a Jew who is one inwardly; and circumcision is of the heart, spiritual, not literal, whose praise is not of men, but of God.
