Perhaps for full preterists, but that cannot be rightly said of partial preterists, unless he thinks the majority of his own denomination spends more time preaching their eschatology than proclaiming the Gospel (which only reinforces the foolishness of his statement since it is far from the truth).
Do you agree that that is what he says....more time seeking converts to preterism?
The proof text of preterism is “this generation shall not pass until all these things be fulfilled.”
In that list of prophecies in Mt 24 is the prophecy of Jesus’ own return. It is among the “ALL of these things.”
That means any variety of preterist MUST believe that Jesus returned in that generation.
Do you?
