A new pastor was visiting the homes of his parishioners. At one house it looked like someone was at home because a car was in the driveway. The pastor knocked several times but no one answered the door. So the pastor took out a card and wrote “Revelation 3:20” on the back of the card. (“Behold, I stand at the door and knock.”) He then left it in the door.
The next Sunday, he found that his card had been returned in the offering plate. Underneath where he had written “Revelation 3:20” was written “Genesis 3:10.”

He got out his Bible to check the passage, and laughed to find that Genesis 3:10 reads, “I heard your voice in the garden and I was afraid, for I was naked.”
