If The Rapture Takes Place Before The Tribulation Period Then What About The "Last Trumpet" In 1st Corinthians 15?

 1 Corinthians 15:51-52: "Behold, I tell 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 trumpet. For the trumpet will sound, and the dead will be raised incorruptible, and we shall be changed."

Here's a Rapture passage and in it, we are told that it will occur at the last trumpet. In Revelation 11 verse 15 (connect with Rev. 8:2) we are told that the seventh trumpet will sound. So does this mean that the Rapture will take place, not before the Tribulation but somewhere in the period when the Tribulation is going on?

Answer:

No, the seventh trumpet is not one and the same with the last trumpet even though the seventh trumpet is the last in the series of seven trumpets in Revelation.

The "last trumpet" in 1 Corinthians 15 is a military trumpet, specifically the last trumpet in the Roman military.

It is very interesting that Paul mentions "trumpet" in 1st Corinthians chapter 15 and then if you look back to chapter 14 of the same book, he mentions a military trumpet. Look:

 1 Corinthians 15:51-52: "Behold, I tell 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 trumpet. For the trumpet will sound, and the dead will be raised incorruptible, and we shall be changed."

1Co 14:8 For if the trumpet makes an uncertain sound, who will prepare himself for battle?

And it just so happened that in the Roman military, there was what they call the "last trumpet" call.

When the last trumpet is blown with its distinct sound, Roman soldiers would stop fighting. It was a call that says: "Stop fighting! It's time for you to rest and go home."

In addition, the "last trumpet" also signals a guard on duty that his shift is over. That it's now time to go home. Roman guards would watch and watch and watch all night and then the "last trumpet" with its notable sound is called. And then, it's time for him to go home; his watch, his guard duty is over.

Moreover, the last trumpet with its distinct sound was also sounded when the Roman army was about to go. The first trumpet told them to prepare. The second told them to fall in line. And the third and last trumpet, off they go and march.

The apostle Paul did not have to tell them about what this last trumpet is because being under the Roman empire, they very well knew what this last trumpet was.
