For almost four decades (yikes!) I’ve worked as a freelance writer, feeling enormously blessed to make a good living by writing about issues of faith that I would want to explore even if no one bought my books. Every year my royalties go down, though with more than 20 books in print I can still pay bills and find publishers willing to sponsor new books.The changes in publishing, especially Christian publishing, stood out sharply to me when I stopped in at the largest annual Christian book convention in June. At one time 15,000 attended that trade show, a convention so large that only a handful of cities could accommodate it. Now less than 4,000 attend, and in Atlanta it occupied a corner of the huge convention center. A couple hundred delegates attended a luncheon in which I participated on a panel with Ravi Zacharias and Ryan Dobson; ten years ago the same luncheon would have filled a thousand-seat banquet hall. Though name authors had book signings, the only lines I saw were for two stars of Duck Dynasty.
