Circumcision Of The Heart

Romans 2:17 thru 2:29
Indeed you bear the name of a Jew, and rest on the law, and glory in God, and know his will, and approve the things that are excellent, being instructed out of the law, and are confident that you yourself are a guide of the blind, a light to those who are in darkness, a corrector of the foolish, a teacher of babies, having in the law the form of knowledge and of the truth. You therefore who teach another, don't you teach yourself? You who preach that a man shouldn't steal, do you steal?

You who say a man shouldn't commit adultery. Do you commit adultery? You who abhor idols, do you rob temples? You who glory in the law, through your disobedience of the law do you dishonor God? For "the name of God is blasphemed among the Gentiles because of you," just as it is written. For circumcision indeed profits, if you are a doer of the law, but if you are a transgressor of the law, your circumcision has become uncircumcision. If therefore the uncircumcised keep the ordinances of the law, won't his uncircumcision be accounted as circumcision?

Won't the uncircumcision which is by nature, if it fulfills the law, judge you, who with the letter and circumcision are a transgressor of the law? For he is not a Jew who is one outwardly, neither is that circumcision which is outward in the flesh; 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.
