“Revelation still interprets—and calls us to interpret—the social, political, religious, and economic realities of our every day experience. It does so not by asking us to equate its images with those realities, playing the endless game of ‘pin the tail on the antichrist’ or trying to line up the seven seals with the broadcasts on CNN or reasoning such and such a nation as the real ‘Babylon.’ Rather, Revelation invites Christ-followers into the same process that guided John as he came upon his ‘apocalyptic adjustment’ to the way he looked at and evaluated the world around him, and was thus enabled to communicate this to his congregations, calling them to ever greater levels of covenant faithfulness toward God and the Lamb.” (DeSilva, Unholy Allegiances: Heading Revelation's Warning, 97–98).
David DeSilva's excellent little book, "Unholy Allegiances" is intended to be a simple guide to interpreting the book, not only in its original context, but as part of our modern, liturgical, Christian lives. Indeed, its aimed primarily at Pastors to help them navigate the complexities of a book that everyone "knows about" and no one has studied.
I used this book as part of my preparation for teaching a teen and young adult class on the book (along with Gorman, Koester, etc) and have thoroughly appreciated his approach. If you're looking for an easy, insightful, and personally challenging introduction (not a commentary!) on Revelation, this one's been really enjoyable.
Of note is that this is one of the few books that includes extremely high quality, full color, photos. It's worth buying for that, alone, so that you can better appreciate how coinage and iconography enlightens our view of the book.
