A man was walking through the desert and had not eaten for days. He came across a church, went in, knelt at the alter and prayed, “Good God, give me some food!”
As if by magic a lump of meat dropped at his feet. Overjoyed he ate the food. He came back every day with the same request, and everyday he was rewarded until one day a hand dropped at his feet.
Puzzled he looked up… There was a leper painting the ceiling.
