This book is meant to be a companion and guide through what many deem to be the most perplexing book of the New Testament. As such, it introduces the reader to the kind of literature Revelation is, how to interpret its pervasive symbolism, and sees it as a response to the unique circumstances of seven historical churches in first-century Asia Minor living under the shadow of the Roman Empire. This companion pays special attention to the literary context and flow of argument of John's unique book, while also giving attention to the effect the visions would have had on the first churches. It also pays attention to the more perplexing details of the text. Revelation was primarily a book that called the churches to maintain their faithful witness in the face of a hostile environment. It also continues to speak to the church today, though perhaps not in the way we often think.
