Preterism reads the Bible in a strange way.
It is like an endless stream of misunderstandings being introduced.
Watching preterism explained is like watching the Beverly Hillbillies.
I think that's intended to be insulting, and that won't win you any friends. I'm not a Preterist, but I have benefited from their emphasis on the fact Jesus was addressing Israel at that time, when he was giving the Olivet Discourse. The Gospel had not yet gone out into the nations. And so, Jesus' focus was largely on Israel as God's chosen people, and the Gentiles as pagan enemies of Israel and only future recipients of the Gospel.
With this in mind, what Jesus was prophesying had to do largely with the Jewish People. Their great tribulation would be an age-long position of being out of God's covenant, and for the most part away from their land. Even today, since they've returned to their land, they do not have God's Christian blessings--they only have God's mercy.
So the "great tribulation" was never intended, by Jesus, to be some future Antichristian persecution of the Church and devastating series of judgments from God against the Antichristian world. No, it was a punishment upon the Jews that is horrible only because it covers the entire extent of the NT period.
It is a "great" tribulation for its duration, and for the fact it includes all of the pogroms and holocausts of Jews in history. It is the longest exile in Israel's history, and thus a "great tribulation." It nearly destroys Israel as a people, and thus threatens the promise of God concerning their eternal longevity.
Preterism largely confines this punishment to the Roman destruction of the Jews in 70 AD and thereabouts. But Jesus said, in Luke 21, that it would be an age-long punishment, ending only with the return of Christ.
I do agree with Marty that "all the land" is a frequent way of stating that an entire *region* will be encompassed in some phenomenon. It does not mean universal in the astronomical sense, as we often view it today with our advanced scientific knowledge.
All the earth today could mean global. Or, as just mentioned, it still could just refer to everything within visual distance.
"World" thus means what it means *in context.* And if the context involves an entire civilization, then "the whole world" may refer to an entire civilization and not to the entire globe.
I do owe a debt to Preterists who have helped me focus on this missing piece I had in my eschatology. Jesus was *not* speaking largely of the endtimes, just before the return of Christ. In fact, in speaking of the 2nd Coming he intentionally marginalized its importance in terms of developing a prophetic calendar or timing scheme. It's value consisted of the fact it will eventually bring eternal judgment for what we are doing *now!*
Therefore, Jesus' Olivet Discourse makes sense when looking at the 1st generation, with its initial signs of the imminent coming of the Roman Army to destroy Jerusalem. Those "birth pains" only make sense as a witness to what was coming soon upon the Jewish unbelievers.
And so, Jesus told his disciples to flee when they saw the Abomination of Desolation, mentioned in Dan 9. This judgment was not intended for them. They were to "flee," and not expect to be "raptured." The Pretrib Rapture theory has less history than Preterism. And the historical view of the AoD and of the Olivet Discourse was also shared by the Church Fathers, for the most part.
I don't agree that the Antichrist was Rome. But Rome certainly was the beginning of the Beast system that will lead up to the future Antichrist. Just my opinion, and I'm trying to do it without insult. Not easy, huh? ;)
