This is the typical type of Revelation study that views the book through the lens of 21st-century American Christianity. But John wasn't a 21st-century American, so an interpretation from the modern-day perspective is simply historically incorrect. I listened through the end of chapter 3, and so I ended up wasting several hours. By the end of chapter 3, Armstrong concludes that John prophesied the rise of Biblical criticism and evolution in the 19th century, and gay marriage and diet fads in the 21st century. This type of interpretation is lazy (because it doesn't bother doing the historical research) and self-centered (because it interprets the Bible as if it were written to 21st-century Americans). It appeals to Americans like cotton candy appeals to preschoolers. But if you really want to understand Revelation, I recommend reading David deSilva, Craig Keener, and Richard Bauckham. It will take more work, but they'll provide you with a historically grounded, scholarly, intellectually respectable interpretation while still remaining committed to the truth of God's Word.
