You're the one with the problems, plural, not me.
First of all, how in the world does this portion of scripture allegedly teach a pre-trib rapture? Is Paul here describing the same trumpet blast that he described in I Corinthians chapter 15? If so, then that is the last trump with no future trumpets to sound after it and it perfectly coincides with the events described in Revelation in relation to the 7th or last trumpet sounding.
Furthermore, where does this passage say that those who meet the Lord in the air are allegedly then going to heaven with Him? That's a bunch of non-Biblical nonsense. Paul told us exactly for what purpose the saints are going to receive their glorified bodies:
I Corinthians chapter 15 verses 50 thru 55
Now this I say, brethren, that flesh and blood cannot inherit the kingdom of God; neither doth corruption inherit incorruption.
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.
For this corruptible must put on incorruption, and this mortal must put on immortality.
So when this corruptible shall have put on incorruption, and this mortal shall have put on immortality, then shall be brought to pass the saying that is written, Death is swallowed up in victory.
O death, where is thy sting? O grave, where is thy victory?
According to Paul, the saints receive their glorified bodies at the last trump because flesh and blood cannot inherit the kingdom of God. In other words, the saints need glorified bodies in order to be able to inherit God's kingdom. Where then is God's kingdom? In heaven or on earth? Jesus taught us to pray, Thy kingdom come, but you and others have us going to it instead of it coming to us. In other words, you've got the whole thing backwards.
