The Reverend Billy Graham tells of a time early in his career when he arrived in a small town to preach a sermon. Wanting to mail a letter, he asked a young boy directions to the post office.
After being told the way by the lad, the Reverend Graham thanked him, adding: "If you'll come to the Baptist church this evening, you can hear me telling everyone how to get to Heaven."
"I don't think I'll be there," the boy said. "You don't even know your way to the post office."
