In a very real sense, the 'change' of/on those who are still alive is a form of death-and-resurrection - only, in singular timing - because, the mortal body dies as the 'change' is occurring.
I'm not sure if you are saying that our "mortal bodies" (by your use of the word "dies") means that our "mortal bodies" will be lying around on the ground/wherever ("dead") once the "change" occurs, and we are then "caught up" [/snatched]... to the meeting of the Lord in the air.
Is this what you are intending to convey by the phrase "the
mortal body dies as the 'change' is occurring"? Just wondering.
Phil3:21 -
Berean Standard Bible
who, by the power that enables Him to subject all things to Himself,
will transform our lowly bodies to be like His glorious body.
Berean Literal Bible
who
will transform our body of humiliation, conformed to the body of His glory, according to the working enabling Him even to subdue all things to Himself.
King James Bible
Who
shall change our vile body, that it may be fashioned like unto his glorious body, according to the working whereby he is able even to subdue all things unto himself.
In 2Cor5, the word
"unclothed" refers to when a believer's mortal body
DIES (what 1Cor15 refers to as "
this corruptible"--re: the
DEAD in Christ" component of "the Church which is His body");
whereas the word
"clothed upon" refers to when a believer's mortal body (i.e.
still-living body--the "we which are
ALIVE and remain unto" component of "the Church which is His body"--"
this mortal" in 1Cor15) is immediately "clothed upon" with our glorified body APART from having to DIE first...2Cor5:4 speaks of "
so that mortality [the '
still-living' component of the Church which is His body] might be swallowed up OF LIFE" (no "death" occurred... but a "change" did... in fact, it was "transformed"... by His POWER ^ );
Paul's point here being that no one "LONGS" / is "EARNESTLY DESIRING" to DIE...
(be "
unclothed"--apart from a body, for a time... until the rapture point in time, at which time "the
DEAD in Christ SHALL RISE [be resurrected from the dead] FIRST" before we're "caught up together with" them--with "changed" bodies),
...though we are "WILLING" for that, if God so wills that we DIE prior to that point in time (when the "change" and rapture occurs).
What we are "EARNESTLY DESIRING" is to be "clothed upon" (that is, immediately "clothed upon" with our glorified bodies APART from having to DIE first--which occurs at "our Rapture" time-slot, of course);
2Cor5, though
also covering the fact that those of us who DIE beforehand will indeed "be at home with the Lord" (awaiting the "shall RISE first" thing, about being
"resurrected" bodily from the graves, i.e. "to stand again" on the earth), is primarily about what will occur are the time that the "
still-living" component (i.e. "THIS mortal" or "mortality"--
still ALIVE ones) of "the Church which is His body" is "changed / transformed / swallowed up OF LIFE" ("THIS mortal must PUT ON immortality"... and "CLOTHED UPON" means there's no shedding of a "mortal body," like, laying around on the ground, left behind to rot or for the birds to feast on [
not sure if that's even what you meant, by the way ]... esp. because of what Phil3:21 says too: "shall
transform our body of humiliation
conformed to..." means,
that very body "changed" / "glorified").
[
by the way, for the readers, "
THIS corruptible" and "
THIS mortal" (1Cor15) speaks specifically to/for/about "the Church which is His body"--at "our Rapture" time-slot--It is not referencing (
in this context) the saints who will be resurrected ('to stand again'
on the earth) at the time-slot of His Second Coming
to the earth Rev19 (OT saints; and Trib saints who will have
died in the Trib yrs),
nor those saints who will ENTER the MK age as "still-living" ones (
many passages in the Gospels covering THESE persons/saints), who will be the ONLY ones with the capacity of reproducing / bearing children during the MK age; note: ALL saints who had previously DIED will be resurrected
IN TIME FOR /
BY THE TIME OF and TO BE PRESENT FOR the commencement of the MK age (aka "the wedding
FEAST / SUPPER"... which [
passages covering this] takes up the next scene in the chronology, when He "RETURNS"
to the earth Rev19 ("when he will
RETURN FROM the wedding"
Lk12,
THEN "the MEAL [G347]"/aka
earthly MK age), and WE / "the BRIDE / WIFE [singular]" return "WITH [G4862-UNIONed-with] Him"/"shall APPEAR WITH [G4862] Him in GLORY"... but there are at that time "saints" still existing on the earth upon His RETURN there, who NEVER LIFT OFF the earth (they are not promised the "SNATCH / RAPTURE / CAUGHT UP" thing)]
