So, as we have seen this brief article, there are very good reasons why the preteristic view of Bible prophecy should be rejected.

Preterists’ proof texts fail to support their own view
None of the church fathers mentioned Christ’s Second Coming as having already occurred
The Christians alive during A.D. 70, as well as the church fathers, believed the Second Coming was a future event.
A strong case can be made that the Book of Revelation was written in approximately A.D. 95, long after the events of A.D. 70.
The Roman emperor Nero could not possibly have been the Antichrist or “the Beast” as preterists suggest.
The Tribulation events in the Book of Revelation are too global and cataclysmic to be attributed to the destruction of Jerusalem in A.D. 70.

Any one of these reasons alone is great reason to doubt the preterist position. All six of these reasons taken together are reason to reject this view of Bible prophecy outright."
