Paul, when he used that word "departure [G359 -
analysis ]" (2Tim4:6), he was referring to his death (per context).
However, "rapture [G726 -
harpagēsometha ]" (1Thess4:17), when the entire corporate "Church WHICH IS HIS BODY" will be "SNATCHed-up/-away]"
at once (in ONE "snatch-action"), that is
NOT equivalent (in any way) to the word or idea of [our] "death" (
nor the idea of "sleep through Jesus" speaking of our "death").
(It will also involve our bodies, although they will be "
changed in a moment" i.e. to "
glorified" bodies; Phil3:21 "that it might be fashioned like unto His glorious body..." [i.e. what 2Cor5:4's "clothed-upon" speaks to also... that is, when we get our "glorified bodies"--"changed in a moment"])
