" If you are strong-headed, read about Moses and Peter. If you lack courage, look at Elijah. If there is no song in your heart, listen to David. If you are a politician, read Daniel. If you are morally corrupt, read Isaiah. If your heart is cold, read of the beloved disciple, John. If your faith is low, read Paul. If you are getting lazy, learn from James. If you are losing sight of the future, read in Revelation of the Promised Land. "
