James 1:23-25

Because if anyone is a hearer of the word and not a doer, he is like someone looking at his own face in a mirror. For he looks at himself, goes away, and immediately forgets what kind of person he was. But the one who looks intently into the perfect law of freedom and perseveres in it, and is not a forgetful hearer but a doer who works — this person will be blessed in what he does.
