Indeed. As far as I’m concerned, the easiest way to show these claims false is to simply note that the two resurrections of the dead, prophesied not only in Revelation, but by the apostles, and by Jesus, obviously haven’t happened, or we would not be here arguing about this.
The only way preterists can answer this, in my experience, is to claim that the events didn’t happen as the Bible predicted they would, but only happened in some “spiritual” sense that basically renders them meaningless, and falsifies the promises associated with them.
Jesus had to deal with people making similar arguments, so I’ll let His response answer these modern-day Sadducees:
“18 Then come unto him the Sadducees, which say there is no resurrection; and they asked him, saying,
19 Master, Moses wrote unto us, If a man’s brother die, and leave his wife behind him, and leave no children, that his brother should take his wife, and raise up seed unto his brother.
20 Now there were seven brethren: and the first took a wife, and dying left no seed.
21 And the second took her, and died, neither left he any seed: and the third likewise.
22 And the seven had her, and left no seed: last of all the woman died also.
23 In the resurrection therefore, when they shall rise, whose wife shall she be of them? for the seven had her to wife.
24 And Jesus answering said unto them, Do ye not therefore err, because ye know not the scriptures, neither the power of God?
25 For when they shall rise from the dead, they neither marry, nor are given in marriage; but are as the angels which are in heaven.”
Since we are not like “angels which are in heaven”, and we still marry, then according to Jesus, we have not been resurrected. Thus the two resurrections prophesied multiple times, both inside and outside Revelation, can not have taken place.
