To me, I believe the Book of Revelation is the most important book in the Bible, they are the last words spoken to us by our Lord Jesus Christ, and it is further explanation of many future events spoken and recorded in other parts of the Bible. All three are the same. The book of Revelation is a complex book, simular to some of the others books in the Bible, in that it repeats itself which I have stated befor. If you do not see this repeat it is impossible to understand. But the Book of Revelation is more complex than probably any other book in the Bible.
Some people incorrectly call it the end of the world.
To make matters harder to understand, the 22 chapter breaks have only been added in the last 100 years or so, and they are misplaced and so, make it confusing. The Book of Revelation is really four books or Chapters built into one book. Few people understand this. Becaues of it's importance, I want to be sure you understand it. The first 5 Chapters are kind of an introduction to the main story.
