James 1:23-24

‘For if any one is a hearer of the word and not a doer, he is like to a man beholding his natural face in a mirror, for he beholds himself, and goes away, and immediately forgets what manner of man he was.'

He then illustrates his argument by the picture of a man who goes and glances in a mirror. He sees himself, but does not weigh himself up, and he then goes away and forgets what little he has observed and what he is supposed to be, and does nothing about what he has seen. It has not affected his actions. And this is like a man who hears the word, and then conveniently forgets what he is supposed to be and does not do it. It does not affect his actions. It is supreme folly.
