This verse is parallel to I Thessalonians 4:15-17. The phrase "the kingdom of God" in I Corinthians parallels "the coming of the Lord" in I Thessalonians. Likewise, "the last trumpet" parallels "the trumpet of God." The last trumpet announces both the resurrection of the saints and Christ's triumphant return to earth to set up His Kingdom! Revelation 11:15-18 confirms when the last trumpet sounds.
In Revelation 7:1, time and events were held back, but once the seventh trumpet sounds, things will unfold without interruption until their conclusion.
This last - seventh - trumpet announces the coming of Christ, the establishment of God's Kingdom, the judgment upon the nations, and the rewarding of the saints. They occur simultaneously!
The last trumpet sounds when Christ returns, not 3½ years before! If we compare verses 11-13 (the resurrection of the Two Witnesses) with verse 19, the "great earthquake" ties the resurrection of the saints with the beginning of the Kingdom (see also Revelation 16:18). In addition, an angel tells John in Revelation 10:7 that when "the seventh angel . . . is about to sound, the mystery of God would be finished." There will be no more mystery about man becoming God when the saints are resurrected or changed to eternal spirit beings!
Matthew 24:30-31 also verifies this scenario, showing that the trumpet sounds to send the angels to gather the elect from all over the earth to meet Him upon His return. To clinch the argument, verse 29 very plainly says, "Immediately after the tribulation of those days. . ."! Isaiah 27:12-13, Joel 2:1-11 and Zechariah 14:3-5, 9 also confirm these events.
