Which view you hold comes down to how you interpret the last trump of 1 Cor. 15:52,
"In a moment, in the twinkling of an eye, at the last trump: for the trumpet shall sound, and the dead shall be raised incorruptible, and we shall be changed."
The last trump here is for the church age while the seventh trump in Revelation is in the tribulation
. There is no mention of the rapture in the seventh trump in Revelation 11:15-19 nor at His second coming in Revelation 19. This is significant.
Note what Charles Ryrie says,
1
Cor. 15:52 speaks of the last trumpet.
Post-tribulationists believe this is the seventh trumpet in Rev. 11:15-19. The
trumpets in Revelation pertain to judgments in the tribulation while I Cor. 15:52 pertains to the rapture of the church. 1 Cor. 15:50-58 and 1 Thess.
4:13-18 omit any reference to judgment. So many
believe this is the sounding of the trumpet at the end of the church age.
Charles Ryrie says, “Mid-Tribulationism argues that
the seventh trumpet of Rev. 10:7 corresponds to the last trumpet of 1 Cor. 15:52. If this be true, then the Rapture (described in 1
Corinthians) will occur at the midpoint of the Tribulation (the time when the
seventh trumpet sounds). This is a somewhat simplistic argument that assumes
that all blowing of trumpets must indicate the same kind of event. This is not
true. In Jewish apocalyptic literature, trumpets signaled a variety of great
eschatological events, including judgments, the gathering of the elect, and
resurrection. The seventh trumpet is a trumpet of judgment, whereas the trumpet
in 1 Corinthians is one of resurrection and deliverance. That they indicate the
same event is an assumption.”
