Behold, I tell you a mystery; we will not all sleep, but we will all be changed,
52 in a moment, in the twinkling of an eye, at the last trumpet; for the trumpet will sound, and the dead will be raised imperishable, and we will be changed.
53 For this perishable must put on the imperishable, and this mortal must put on immortality.
(1Co*15:51-53*NAU)
Here again, Paul fails to mention a rapture before the tribulation, that is, at the first trumpet.
This would have been a good place for him to expound on this burning question: Will those who participate in the pre-trib rapture take on their glorified bodies then, or will they have to wait for the rest of us?
