Be a mirror for Jesus.

From James 1:23-25:  “For if any are hearers of the word and not doers, they are like those who look at themselves in a mirror; for they look at themselves and, on going away, immediately forget what they were like.  But those who look into the perfect law, the law of liberty, and persevere, being not hearers who forget but doers who act—they will be blessed in their doing.”
