Be doers of the word and not hearers only, deluding yourselves.  For if anyone is a hearer of the word and not a doer, he is like a man who looks at his own face in a mirror.  He sees himself, then goes off and promptly forgets what he looked like.  But the one who peers into the perfect law of freedom and perseveres, and is not a hearer who forgets but a doer who acts, such a one shall be blessed in what he does.

James 1:21-25
