Jesus being the greatest prophet, like the prophets before him, simply looked beyond 70 AD to the end time. He used the prophetic projection used by the inspired prophets. AD 70 was but the precursory “near” fulfillment.
Jesus went to be with God long before the end of Revelation, also there was war in heaven and Satan was cast down to earth.
So I don`t see how all of revelation could be about the destruction of Jerusalem.
“I can see the argument the preterist make as far as the gospels are concerned but Revelation is far different.”
Revelation is different, not sure what you meant about the gospels. What argument the preterist make? Matt. 24:34?
