CLAIM: This is the most informative passage in Scripture on the resurrection. In verses 24-28, Paul describes Jesus’ reign in the Millennial Kingdom. In verses 35-49, he reveals the glory in the resurrected body. Finally in verses 50-55, Paul speaks of the mystery pertaining to the generation of believers that will not die, but instead, will be conveyed from mortality to immortality, instantaneously at the return of Christ.
True that this is an end times passage.
The claim that v24-28 is the Millennial Kingdom does not fit, as it describes death being destroyed. Since the Gog Magog war comes after the Millennium (see Revelation 20), this is most likely not describing that period.
This does speak of the bodily changing of those still alive at the Return of Christ, but not in the timeline they interpret or suggest.
