Romans 2:17

15in that they show the work of the law written in their hearts, their conscience testifying with them, and their thoughts among themselves accusing or else excusing them)

16in the day when God will judge the secrets of men, according to my Good News, by Jesus Christ.

17Indeed you bear the name of a Jew, rest on the law, glory in God,

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

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