The Theology of the Book of Revelation. If there was one book that treated this subject better and yet more concisely than Bauckham, then I wouldn't believe it. This book is a treasure of information. There is nearly a quotable portion on every page. My highlighter eventually ran out of ink on this one. I did resist the urge to post them on facebook just because I knew I would have to change it every 5 minutes. Two thumbs up for the serious student to scholar!
PS-this book has spurred me to read more Bauckham. I am looking forward to reading his larger collected works on Revelation The Climax of Prophecy.
