The pastor was out visiting Paddy Murphy, one day. He didn't announce that he was coming, because he could always visit another parishioner, if Paddy wasn't home. But he was home because Paddy's truck was in the driveway. Father rang the door bell but no one answered. Sound from either a TV or Radio could be heard through the door. Father thought that the bell could be broken, so he knocked on the door, loudly. Still no answer. Father finally took out pen and paper and wrote "Revelation 3:20," and stuck it on the door.
Next Sunday, when Father was counting the offering he found his note, where he had written "Revelation 3:20," and saw that below, Paddy had written, "Genesis 3:10."
