Romans 2
23 Ref You who glory in the law, through your disobedience of the law do you dishonor God?
24 Ref For "the name of God is blasphemed among the Gentiles because of you," just as it is written.
25 Ref 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.
26 Ref If therefore the uncircumcised keep the ordinances of the law, won't his uncircumcision be accounted as circumcision?
27 Ref 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?
28 Ref For he is not a Jew who is one outwardly, neither is that circumcision which is outward in the flesh;
29 Ref 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.
