Excellent dissection of the book of Revelation by Theodore Epp. Long out of print, I found this used (but practically new) on eBay. The study is 2 volumes, and I have only just finished volume 1 (volume 2 is over twice the size). This is the 3rd book study I’ve read regarding Revelation, but it is far and away my favorite, in terms of theology, application, and readability. My only complaint is that the reference scripture is often KJV (King James Version), which is more difficult to read and process than most modern Bible translations. But Epp’s insight, explanation and attitude toward the material and the audience are so great!
