When I Hear a Knock I Hear - John Newton

John Newton was not bothered by the telephone, but he was by people coming to his home. He said, "When I hear a knock at my study door, I hear a message from God; it may be a message of instruction; perhaps a lesson of patience; but, since it is His message, it must be interesting.''

John Newton 1725-1807
