James 1:23-24

Are you like this person? There is this person who is merely a hearer of the word and not a doer. If you are this type of person, you are deceiving yourself. Do not do it. To describe this, the person is described as a person who looks intently at his face in a mirror. This isn't just a quick glance, but a careful inspection of a person's own face. Afterwards, this person goes away and immediately forgets what he looks like. That's ridiculous! Why would he look at his face in the mirror if he was just going to forget soon after? This is what you are like when you hear the word and do not do what it says.
