Shortly before his death, the author [Dr Silkworth] spent an hour with Dr. Norman Vincent Peale, friend of A.A., the Rev. Sam Shoemaker, and Bill Wilson. Dr. Peale told me of the conversations he had with Bill Wilson about Bill's conversion. However, until 1997, I had never heard
the following account by Peale about Dr. William Duncan Silkworth. It can be found in Norman Vincent Peale, The Positive Power of Jesus Christ (New York: Foundation for Christian Living, 1980), pp. 60-61. It appears under the title "The Wonderful Story of Charles K.":
Charles, a businessman in Virginia, had become a full-fledged alcoholic; so much so that he had to have help, and fast, for his life was cracking up. He made an appointment with the late Dr. William Duncan Silkworth, one of the nation's greatest experts on alcoholism, who worked in a New York City hospital [the Charles Towns Hospital]. Receiving Charles into his clinic as a patient, the doctor gave him treatment for some days, then called him into his office. "Charles," he said, "I have done everything I can for you. At this moment you are free of your trouble. But there is an area in your brain where you may hold a reservation and that could, in all likelihood, cause you to return to your drinking. I wish that I might reach this place in your consciousness, but alas, I do not have the skill."
"But, doctor," exclaimed Charles, "you are the most skilled physician in this field. When I came to you it was to the greatest. If you cannot heal me, then who can possibly do so?" The doctor hesitated, then said thoughtfully, "There is another Doctor who can complete this healing, but He is very expensive."
"That's all right," cried Charles, "I can get the money. I can pay his fees. I cannot go home until I am healed. Who is this doctor and where is he?"
"Oh, but this Physician is not at all moderate as to expense," persisted Dr. Silkworth. "He wants everything you've got. He wants you, all of you. Then He gives the healing. His price is your entire self." Then he added slowly and impressively, "His name is Jesus Christ and He keeps office in the New Testament and is available whenever you need Him."
