During the Lord’s Day, God’s wrath is actually poured out over the inhabitants of the earth. After the sixth trumpet, one third of humanity dies, and only after the 7th trumpet follows the resurrection – this means that believers will have to be on the earth for a long time, waiting for the rapture.
The resurrection/rapture takes place according to the Corinthians and the Thessalonians in the coming of Jesus: 1 Cor 15:52 in a moment, in the twinkling of an eye, at the last trumpet; for the trumpet will sound, and the dead will be raised incorruptible, and we shall be changed.
1 The 4:16 Because the Lord Himself shall come down from Heaven with a commanding shout of an archangel’s voice, and with God’s trumpet. And the dead in Christ will rise again first.
Rev 9:13 And the sixth angel sounded. And I heard one voice out of the four horns of the golden altar before God,
14 saying to the sixth angel who had the trumpet: Release the four angels, those having been bound at the great river Euphrates.
15 And the four angels were released, those having been prepared for the hour and day and month and year, that they should kill the third part of men
The sixth trumpet sounds and the four angels are ready to kill one third of the people. Only four angels are needed to execute God’s will – killing of one third of humanity. How great are the forces of heaven in power! When the next i.e. the 7th trumpet sounds, Christ comes with his angels. One of the trumpet sounds separates the saints and the living Christ’s own from the first resurrection and rapture to meet Jesus in the clouds.
Also Matthew writes about what happens after the days of tribulation: the sun is darkened, the powers of the heavens are shaken and the sign of the Son of Man can be seen in the sky and people see Jesus come with great power and glory.
