My first book was written with the Rev. Grover Gunn and titled Dispensationalism Today, Yesterday, and Tomorrow. It went through three editions and six printings. I’m receive more emails and calls about that book, to this day, than any others, asking me to update it and reprint it. I’m considering that. It was a loving critique of dispensationalism, and since our first edition, there are now three competing kinds of dispensationalism: classic dispensationalism (Lewis Sperry Chafer and C. I Scofield), moderate dispensationalism (Walvoord, Pentecost, Ryrie), and now progressive dispensationalism (too many to mention, but Blaising and Bock are representative). First published in early 1985. If you can find the third edition and sixth printing, it will explain these various views, how they are similar and how they differ.
