I admittedly place little theological stock in Revelation. It was one of the most disputed books in terms of whether is should be in the Bible at all. I don't say it has no relevance to today, but I have always felt it was written principally to exhort and reassure a contemporaneous audience, which makes me a preterist to that extent. I feel it receives way too much attention.
Matthew 24 and the corresponding chapters in Mark and Luke are confusing to read. A popular scholarly view is that Jesus was answering two questions and talking about two events - the imminent destruction of the Temple and his future Second Coming. He can scarcely be talking about imminent events that are going to happen in 25 or 30 years when he says:
Nation will rise against nation, and kingdom against kingdom. There will be famines and earthquakes in various places. All these are the beginning of birth pains.
Then you will be handed over to be persecuted and put to death, and you will be hated by all nations because of me. At that time many will turn away from the faith and will betray and hate each other, and many false prophets will appear and deceive many people. Because of the increase of wickedness, the love of most will grow cold, but the one who stands firm to the end will be saved. And this gospel of the kingdom will be preached in the whole world as a testimony to all nations, and then the end will come.
