In 2000 I was challenged by a student who was a regular attender of my weekly Spiritual Warfare Sunday School class to write a book. I replied that I did not have the time to 'write' a book -- thinking that would be the end of the discussion. But that was only the beginning, as that student replied with, "But the book is already written." What do you mean? "Well for weeks now we have been taping all of the class messages and now all you have to do is listen  and transcribe them into the computer."
