Many posttribulationists believe that the rapture will happen after God’s eschatological wrath, the trumpet judgments and some believe even the bowls.
But this contradicts Jesus and Paul’s teaching that the sudden separation will happen to the wicked “as in the days of Noah” and “as a thief.”
We are told by posttribulationists to believe that after the world is pummeled by God’s wrath in the trumpet judgments, including a third of humankind dies, only then the world will be like “oh, looking back this must have been God’s wrath.”
Of course this is absurd. It is like saying that after weeks of enduring the flood—assuming any survived that long—the wicked realized they they were in a flood!
Instead, the consistent point that Jesus, Paul, and the book of Revelation makes is on the same day that God’s delivers the righteous, that day is when God’s eschatological wrath begins suddenly upon the wicked.
When you hold on tight to the presupposition “the rapture occurs at the seventh trumpet,” you have to twist what other scripture says to make if fit your tradition.
