You answered your own question: WHO's trumpet is it? Sorry, but Gabe' is not going to blow God's trumpet. If He blows a trumpet, it will be his own.
That is not a good enough reasoning. Where does it say that the first trumpet is not
of God ? Revelation 8:2
says "And I saw the seven angels who sand before God, and seven trumpets were given to them."
All the trumpets blown by the angels are trumpets of God too.
Whoever else do the seven trumpets belong to if not to God ?
The sounder of the trumpets is not a very good reason to insist that Paul's "last trumpet"
could not be the seventh trumpet. I will look for a better reason if someone has one.
I don't fight with scriptures; I believe them: when it says trump of God, why would you believe anyone else would blow it?
Whether God is the blower or not, it is not sufficient reason to insist that Paul's mention of the last trumpet, cannot be the seventh trumpet in John's Revelation.
The Owner of the the last trumpet Paul mentions is God. The Owner of the seven trumpets blown by the seven angels who stand before God is also God.
So your pointing out that "the trumpet of God"
proves that that cannot be the seventh trumpet, is not conclusive reasoning IMO.
I understand John's chronology. I know where the rapture is in revelation, and I know that it comes before the 7th trumpet. If you would believe John, you would believe that too. When did Paul say his rapture would be? Just three verses after the classic rapture verse, Paul mentions the day of the Lord, as if that Day had some connection to the rapture. He goes on to say that while those in darkness get the sudden destruction of the first day of the Day of the Lord, WE get salvation by way of rapture, and get to live together with Him. Therefore, Paul is telling us plainly that the rapture comes BEFORE the day of the Lord. In fact, the rapture is the TRIGGER for that Day.
We all need a firm hope. And as your brother in Christ, I do not want to give impression that I am against your firm hope.
So, I think I will not argue about this anymore. Come Lord Jesus. I have a thread on "I Expect a Selective Rapture".
And instead of repeating, I think that thread is where I will answer questions about my expectation and hope.
It is wonderful that our Lord comes. Let us prepare ourselves to meet our wonderful and victorious Lord Jesus.
