Before I get into the book of Revelation, I want to focus your attention on a particular fact. The Olivet Discourse is recorded in the gospels of Matthew, Mark and Luke, but there is no Olivet Discourse in the gospel traditionally named John. John gives us the Revelation, but Matthew Mark and Luke do not. If you look at the Olivet Discourse what do you see? You see death, pestilence, famine, disaster, the destruction of Jerusalem, judgment, and the gathering of the elect. What do we see in the book of Revelation? We see death, pestilence, famine, disaster, the destruction of Jerusalem, judgment, and the gathering of the elect. Because there are so many similarities in wording, and based on the dating of Revelation, it is my belief that the Book of Revelation is John's Olivet Discourse. I believe it was written in perhaps 66-67AD, and simply is much more comprehensive than the gospel narratives. It points to the events that would shortly come to pass. Remember, John said it was the "last hour" (1st John 2:18).
