Romans 2:17

15 in that they show the work of the law written in their hearts, their conscience bearing witness therewith, and their thoughts one with another accusing or else excusing [them]);

16 in the day when God shall judge the secrets of men, according to my gospel, by Jesus Christ.

17 But if thou bearest the name of a Jew, and restest upon the law, and gloriest in God,

18 and knowest his will, and approvest the things that are excellent, being instructed out of the law,

19 and art confident that thou thyself art a guide of the blind, a light of them that are in darkness,

20 a corrector of the foolish, a teacher of babes, having in the law the form of knowledge and of the truth;
