Romans 2:25-29 - Circumcision Of The Heart
25 Circumcision indeed profiteth, if thou keepest the law; but if thou art a transgressor of the law, thy circumcision is become uncircumcision. 26 Therefore if the uncircumcision keep the righteousness of the law, shall not his uncircumcision be counted for circumcision? 27 Yea, the uncircumcision that is by nature, fulfilling the law, shall judge thee, who by the letter and circumcision transgressest the law. 28 For he is not a Jew, who is one in outward shew, neither is that circumcision which is apparent in the flesh. 29 But he is a Jew, who is one inwardly, and circumcision is that of the heart, in the spirit, not in the letter; whose praise is not from men, but from God.
