Romans 2:27-29

NSB(i) 27 The uncircumcised person is by nature, fulfilling the law. He will judge you because you transgress the law with your written code and circumcision. 28 He is not a Jew who is one on the outside. Neither is circumcision that which is on the outside in the flesh. 29 But he is a Jew who is so on the inside with circumcision of the heart, in spirit, not in letter; whose praise is not of men, but of God.
