The statement by Paul in 1 Thess.4:16, "...and the dead in Christ will rise first," does not mean a resurrection is about to occur. Because they were all raised once before, as those who die in Christ, according to 2 Cor.5:6-8, and as FIRSTFRUITS, each in his own turn, according to 1 Cor.15:23. Who will return with Jesus when He comes with them from heaven, according to vs 14. If Paul meant it was to be a resurrection, he would have documented it as one, which he did not do. If he had, there would be three resurrections rather than the two that are recorded in Rev.20:4-6, Which Jesys told John, is the FIRST resurrection, AFTER His second coming WITH His Church from heaven, recorded in Rev.19:14.. Which would then have to be changed from the first and second, to the second and third resurrections. 1 Thess.4:13-18 has nothing whatever to do with the second coming of Christ to the earth, as documented in Mt.24:30; Zech.14:4-5; Jude 14 and Rev.19:14, when the Pre-trib raptured Church RETURNS WITH CHRIST!
But rather than meaning it to be a resurrection, it was the third of Paul's assurances to the Thessalonians, that all the members of their church, who had already died in Christ, would not miss the pre-trib rapture of the Church he was teaching them about.
The first of Paul's three assurances begins in vs 13: "Brothers, we do not want you to be ignorant about those who fall asleep [die], or to grieve like the rest of men [non-believers], who have no hope." [Parenthetics mine].
Then he followed up his first assurance to them that all those who had previously died in Christ would be together with them at the rapture of the Church in the very next verse [14]: "We believe that Jesus died and rose again and so we believe that God will bring with Jesus those who have fallen asleep in Him." Revealing to them, that Christ had previously raised them all once before, as documented in 2 Cor.5:6-8, and had been in heaven with Him ever since. Since all the dead in Christ have been raised once before, there is no reason for them having to be raised a second time. Confirming their status as FIRSTFRUITS, raised each in his own order, according to 1 Cor.15:23.
There will not be any resurrected then, because all their dead in Christ had already been raised once before, in their spiritual bodies [As recorded in 1 Cor.15:44], following the death of their bodies, when they immediately went to be with Christ in heaven. Confirming Ecc.12:7 as well as 2 Cor.5:6-8. Confirmed in 1 Thes.4:14, saying they are returning with Christ, when He returns, from heaven with them. Therefore, when Jesus appears in the clouds of the sky for all those who belong to Him left here on earth alive, they will be caught up together with them in the clouds to meet the Lord in the air [together with those who previously died in Him, who are already there].
The second of Paul's three assurances to the Thessalonians, was that their dead in Christ will not miss the rapture of the Church is in vs 15, which states: "According to the Lord's own word [Recorded in Jn.14:2-4 and 28], we tell you that we who are left [Believers] till the coming of the Lord, will certainly not precede those who have fallen asleep [Died]." Of course not! Because they will have already been raised once before, and gone to be with the Lord in heaven in their spiritual bodies, and then return with Him when He comes from heaven! They certainly do not need a resurrection, because they are going to the spiritual world in heaven. In contrast to the glorified physical bodies that will be necessary at the time of the resurrection documented in Rev.20:4 and 6. Because they are to be priests of God and rule with Jesus for 1,000 years right here on the earth, in a human environment! [Parenthetics mine]
