A 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. Therefore, he took out a business card and wrote “Revelation 3:20” on the back of it 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.”
