The Reverend Billy Graham tells of a time early in his ministry when he arrived in a small town to preach a sermon. Wanting to mail a letter, he asked a young boy where the post office was. When the boy had told him, Dr. Graham thanked him and said, If youll come to the Church this evening, you can hear me telling everyone how to get to Heaven. I dont think Ill be there, the boy said. You dont even know your way to the post office.
