Romans 2:17-20

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.
