I’m happy to say I knew John Kachelman when we were boys. I lost touch with him over the years, but I’m so thankful to know he is a gospel preacher and fine Bible student. His book is an excellent series of lessons on the book of Revelation. He is true to the text and seeks to understand the Apocalypse the way the original recipients understood it. That is the only sensible approach to interpreting the Bible. I appreciate his work very much.
