Currently reading a book about the Apocalyptic movement. When you view apocalypses as a genre with a set format and ingredients such as dreams, visions of heaven, a judgement of good and bad etc and compare it with other apocalypses, like the book of Enoch, fourth Ezra, 2nd Baruch, Daniel too of course; compare it too to apocalypses of Babylonian and Persian origin, it is hard to view any of the book of Revelation as in any way unique or special. It just happened to be included in the bible.
The book of Revelation does not apply to our time. It was describing an imminent end just as Paul also expected an end in their lifetime. It has references to the Roman Empire. The mark of the Beast 666 or 616 as they think it is now, is a code number that identifies a specific Roman emperor. Just like Daniel wasn't referring to our time either. The King of the North and the King of the South - it is the Ptolemies of Egypt and the Seleucid's of Syria, literally to the North and South of Israel in the second century when Daniel was written. These biblical apocalypses are failed prophecy and they have not relevance for us.
