Romans 2:25-29 - Circumcision Of The Heart
25 For circumcision indeed profits if thou keep the law; but if thou be a law-transgressor, thy circumcision is become uncircumcision. 26 If therefore the uncircumcision keep the requirements of the law, shall not his uncircumcision be reckoned for circumcision, 27 and uncircumcision by nature, fulfilling the law, judge thee, who, with letter and circumcision, art a law-transgressor? 28 For he is not a Jew who is one outwardly, neither that circumcision which is outward in flesh; 29 but he is a Jew who is so inwardly; and circumcision, of the heart, in spirit, not in letter; whose praise is not of men, but of God.
