Romans 2:18-20

New Catholic Bible

¹⁸ and you know his will and are able to distinguish between right and wrong because you have been instructed in the Law, ¹⁹ and you are confident that you are a guide to the blind, a light for those in darkness, ²⁰ an instructor of the foolish, and a teacher of the simple because in the Law you have the embodiment of knowledge and truth.
