I actually don't want to retread the general arguments about the way Post-Tribbers garble the chronology of Revelation. I've spoken on them some already. And others supporting different rapture views do it a lot.
I want to address simply one detail in the Seventh Trumpet account itself they see as insisting it can only be placed at the very end of everything that happens.
"The kingdoms of this world are become the kingdoms of our Lord, and of his Christ; and he shall reign for ever and ever."In Revelation 11:15. They insist this must mean it's sounded right when The Millennium begins.
What's amusing is these are Premillennial Futurists making the same basic error Preterists and Amillennials make about various things Jesus said in The Gospels, or the End of Revelation when he says he's coming quickly.
John 12:13 "Now is the judgment of this world: now shall the prince of this world be cast out."
No Futurist thinks that actually happened at that time in it's apparent face value assumption. Satan remains the Prince of This World right now.
While I disagree with a lot of things taught at Nomadic Ministry (like his form of Dual Covenant theology, which influences how he sees certain things in this same chapter). I will quote what he has to say on this detail.
We start out after the trumpet it sounded and a loud voice proclaims that the world has become the kingdom of our Messiah. It is at this point that God takes over the scene and really starts hammering down the judgment that those who are truly left behind deserve. Before this, I believe, the devil was still being given his dominion to work chaos and discord throughout the world. After this trumpet is sounded God takes the forefront and controls the story from here on out.So this one statement certainly does not prove the Post-Trib view.
Post-Tribbers have many points they view as a start over point. There are no Chapter or Verse divisions in the original text, as I've pointed out elsewhere, the Greek word rendered "and" at the beginning of Revelation 12 demands that that vision is still part of the 7th Trumpet event. And reading on in Chapter 12 it's clear then that 1260 days at least are still left when the 7th Trumpet is sounded.
