The new pastor was visiting in the homes of his parishioners. At one house it seemed obvious that someone was at home, but no answer came to his repeated knocks at the door. He took out a card, wrote "Revelation 3:20" on the back and stuck it in the door.
When the offering was processed the following Sunday, he found that his card had been returned. Added to it was this cryptic message, "Genesis 3:10." Reaching for his Bible to check out the citation, he broke up in gales of laughter.
Revelation 3:20 begins "Behold, I stand at the door and knock."
Genesis 3:10 reads, "I heard your voice in the garden and I was afraid for I was naked."
