You can try to force the resurrection of all the righteous into ONE resurrection, but you will be wrong. The truth, as you have stated, is that there are only TWO resurrections mentioned in Revelation 20 for all people, saved and unsaved. One is titled "the first resurrection. I have called the second one, the "second death resurrection.
This paragraph is internally contradicted. You first tell me that there is only 1 resurrection of the saved, and then you tell me there are only 2 resurrections mentioned in Rev 20 for all people. Duh. Right. One for the saved, and one for the unsaved.
That is precisely what Paul said in Acts 24:15 - and I have the same hope in God as these men themselves have, that there will be a resurrection of both the righteous and the wicked.
One each. Obviously. And then Paul clarified even further about WHEN the saved resurrection will occur.
1 Cor 15:23 - But each in turn: Christ, the firstfruits; then, when he comes, those who belong to him.
So, you tell me, from this verse, just WHEN that single saved resurrection will occur.
What you have missed: Jesus own resurrection was the firstfruits of that "first" or most honorable resurrection.
Didn't miss a thing. 1 Cor 15:23 notes that Jesus was the first to be resurrected. And then, WHEN HE COMES, an obvious reference to the Second Coming, "those who belong to Him", which is an obvious reference to EVERY SAVED human from Adam on.
So if you think there will be a pretrib rapture, which occurs with a resurrection, you've got a huge problem with Rev 20, which specifically says the resurrection of trib martyrs is the FIRST resurrection.
The next wave will be the church, resurrected pretrib. The next wave will be the Old Testament saints, resurrected on the last day - the last 24 hours - of the 70th week. (Their resurrection will be marked by the world's worst earthquake.) Along with the OT saints, the Two witnesses and the beheaded will be resurrected at the same time. God did not tell us that this resurrection for all the righteous would happen all at once. Scripture tells us otherwise.
You have been taught false doctrine. There will be only 1 resurrection for the saved, as I have shown from several verses. Your problem is not with me, but with the Word of God.
Luke 14:14 - and you will be blessed. Although they cannot repay you, you will be repaid at the resurrection of the righteous.”
Jesus' words, not mine. THE resurrection of the righteous. One resurrection.
Acts 24:15 - and I have the same hope in God as these men themselves have, that there will be a resurrection of both the righteous and the wicked. Again, just one resurrection for the saved, and one for the unsaved.
1 Cor 15;23 - But each in turn: Christ, the firstfruits; then, when he comes, those who belong to him.
All believers will be resurrected at the same event. There are no "waves" of resurrection as you presume.
