I used to see and in a lot of cases read thousands of Protestant books (Some are still in the house):
Joyce Meyer’s many books, The “Power of a Praying —” series by Stormie Omartian (o-MAR-tee-un), Your Best Life Now by Joel Osteen, several books by T.D. Jakes, the piles of writing by Tim LaHaye, including the LaHaye-originated Left Behind series by Jerry Jenkins, the three books written by Ruth Bailey writing as Rebecca Brown, M.D., the writings of Lauren Stratford under various names, Mike Warnke’s books, Bob Larson’s books, the books of Ed Smith, Bill Schnoebelein, Ed Dekker, Dave Hunt, Paul Crouch, Berit Kjos, Pat Robertson, Tal Brooke, Randall Baer, John Hagee, and many many more. These add up to enough books to keep a person reading, working, sleeping a little and going to church functions 24-7 for life (I guess that’s the point).
Catching a little time for more difficult reading, there was always C.S. Lewis, whom some worried was a liberal and therefore perhaps not a real Christian

uch:, Dietrich Von Bonhoffer (sp?), “God’s Smuggler” (author’s name not coming to mind right now), the work of Martin Luther, and that of Watchman Nee and so many more authors there was no time even to learn who they were.
