Let me try another angle to this. When exactly in relation to the sounding of the seventh and last trumpet, do you believe the following will occur:
1 Corinthians 15:51 Listen, I tell you a mystery: We will not all sleep, but we will all be changed— 52 in a flash, in the twinkling of an eye, at the last trumpet. For the trumpet will sound, the dead will be raised imperishable, and we will be changed.
In the days when the seventh angel begins to sound, after Satan has a little season.
