Illustration: Blind Mules
A man was driving through a mining region one Sunday when he noticed a large number of mules in an open field. When he inquired about this unusual sight, he was told that the work animals had been brought up from the dark passages below to preserve their eyesight. Unless they were regularly exposed to the sunlight, they would eventually go blind. The Christian needs similar experiences to keep him from losing his spiritual vision. The Lord’s Day has been given to aid him in keeping his eyes focused clearly on the TRUE LIGHT!
