Why is a Judaica scholar staring intently at the New Testament book of Revelation? Because even though it's come down to us in Greek, it is at its heart a Jewish book. Its tone and content is of course far afield from Judaism today, but what we're talking about is ancient Judaism – a very different animal.
I often wonder why so many people are interested, indeed fascinated by this book. And my best explanation is that it does for us basically what a roller coaster ride, or the Tower of Terror, does. It scares us to death! And let's face it; for some unknown reason people like to be scared. It gives us a delicious, narcotic-like adrenaline rush.
