What is the book of Revelation all about?

That was one of the questions I answered at the outset of the new series, At Worlds End. It is a book that has mystified many, terrified some and confused others yet in the first five words the book speaks for itself, identifying what, or I should say, who the book is focused on.
Here is a clip from that message:

As we get ready to dive back in and study the second half of chapter 1 get ready to see Jesus like never before. The vision John has of Jesus, the book’s focal point, is definitely not what most people think of when they imagine Jesus in their minds eye. But it is a description that I love and inspires worship and awe. Hold on for the ride!
