James 1:22-24, 26

But be ye doers of the word, and not hearers only, deluding your own selves. For if any one is a hearer of the word and not a doer, he is like unto a man beholding his natural face in a mirror: for he beholdeth himself, and goeth away, and straightway forgetteth what manner of man he was.

If any man thinketh himself to be religious, while he bridleth not his tongue but deceiveth his heart, this man’s religion is vain.
