Romans 2:25-29

25For circumcision indeed profits if thou keep [the] law; but if thou be a law-transgressor, thy circumcision is become uncircumcision. 26If therefore the uncircumcision keep the requirements of the law, shall not his uncircumcision be reckoned for circumcision, 27and uncircumcision by nature, fulfilling the law, judge thee, who, with letter and circumcision, [art] a law-transgressor? 28For he is not a Jew who [is] one outwardly, neither that circumcision which is outward in flesh; 29but 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 1God.
