I do not understand your interpretation of that passage.
I don't believe in the Rapture because I don't see it in the Bible. 1 Thessalonians 4:13-18 is used to support that view, but I disagree. This passage is not about the Rapture at all. “The Lord himself will descend from Heaven with a shout, the voice of the archangel, with the trumpet of God, and the dead in Christ shall rise first” (v. 16). This is a resurrection, not the Rapture. The text says, “the dead in Christ will rise,” so we are talking here about a resurrection at the coming of the Lord. And then it says, “Then we who are alive and remain will be caught up together” — there’s your rapture word, “caught up with him in the clouds to meet the Lord in the air, and so we will always be with the Lord.”
What Paul is saying is that at the coming of the Lord, those who have fallen asleep will be resurrected, so they go from dead to alive in the resurrection. But those who have not died yet will also be resurrected in the sense that they get transformed without having died. Whether or not you agree, I hope I've explained my view of that passage so you see where I'm coming from.
