Romans 2:18-21

WPNT(i) 18 and know the Will, and approve the superior things, being instructed out of the Law. 19 Further, you are confident that you yourself are a guide to the blind, a light to those in darkness, 20 an instructor of the foolish, a teacher of the immature, having in the Law the embodiment of knowledge and truth. 21 You, then, who teach another, do you not teach yourself? You who preach not to steal, do you steal?
