Romans 2:17-28

17Indeed you are called a Jew, and rest on the law, and make your boast in God,

18and know His will, and approve the things that are excellent, being instructed out of the law,

19and are confident that you yourself are a guide to the blind, a light to those who are in darkness,

20an instructor of the foolish, a teacher of babes, having the form of knowledge and truth in the law.

21You, therefore, who teach another, do you not teach yourself? You who preach that a man should not steal, do you steal?

22You who say, “Do not commit adultery,” do you commit adultery? You who abhor idols, do you rob temples?

23You who make your boast in the law, do you dishonor God through breaking the law?

24For “the name of God is blasphemed among the Gentiles because of you,” as it is written.

25For circumcision is indeed profitable if you keep the law; but if you are a breaker of the law, your circumcision has become uncircumcision.

26Therefore, if an uncircumcised man keeps the righteous requirements of the law, will not his uncircumcision be counted as circumcision?

27And will not the physically uncircumcised, if he fulfills the law, judge you who, even with your written code and circumcision, are a transgressor of the law?

28For he is not a Jew who is one outwardly, nor is circumcision that which is outward in the flesh;
