You're assuming this "last trumpet" is the one John wrote about in Revelation.
Thing is, Paul wrote about it before John wrote Revelation. This would indicate Paul had a different trumpet in mind.
Where did Paul write about a different trumpet? Please produce the verses where Paul speaks of a trumpet that shall be different?
Perhaps you're referring to the passage from 1Cor 15:51-52 "
Behold, I shew you a mystery; We shall not all sleep, but we shall all be changed, 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." ???
Do you believe the "
last trumpet" Paul says will come in "
a moment, in the twinkling of and eye" is different than the last/seventh trumpet, or another last/seventh trumpet John says the angel shall sound when time would be no longer?
Revelation 10:5-7 (KJV) And the angel which I saw stand upon the sea and upon the earth lifted up his hand to heaven, And sware by him that liveth for ever and ever, who created heaven, and the things that therein are, and the earth, and the things that therein are, and the sea, and the things which are therein, that
there should be time no longer: But in the days of the voice of the seventh angel, when he shall begin to sound, the mystery of God should be finished, as he hath declared to his servants the prophets.
The following passage says that SEVEN angels sound SEVEN TRUMPETS, but you say Paul is NOT referring to the last/seventh trumpet as John writes in the Revelation?
Revelation 8:1-6 (KJV) And when he had opened the seventh seal, there was silence in heaven about the space of half an hour. And
I saw the seven angels which stood before God; and to them were given seven trumpets. And another angel came and stood at the altar, having a golden censer; and there was given unto him much incense, that he should offer
it with the prayers of all saints upon the golden altar which was before the throne. And the smoke of the incense,
which came with the prayers of the saints, ascended up before God out of the angel's hand. And the angel took the censer, and filled it with fire of the altar, and cast
it into the earth: and there were voices, and thunderings, and lightnings, and an earthquake.
And the seven angels which had the seven trumpets prepared themselves to sound.
