Romans 2:19-25

19and are confident that you yourself are a guide to people who are blind, a light to those in darkness, 20a 1corrector of the foolish, a teacher of 2the immature, possessing in the Law 3the embodiment of knowledge and of the truth-- 21you, therefore, 4who teach someone else, do you not teach yourself? You who 5preach that one is not to steal, do you steal? 22You who say that one is not to commit adultery, do you commit adultery? You who loathe idols, do you 6rob temples? 23You who 7boast 8in the Law, through your breaking the Law, do you dishonor God? 24For “9the name of God is blasphemed among the Gentiles 10because of you,” just as it is written.

25For indeed circumcision is of value if you 11practice 12the Law; but if you are a violator 13of the Law, 14your circumcision has turned into uncircumcision.
