“And if those days [of persecution] had not been cut short, no human being would be saved. But for the sake of the elect those days will be cut short. – Matt 24:22 ESV

Traditionally, the Great Tribulation has been assumed to be 3 1/2 years in duration (i.e. the entirety of the second half of the future seven year period.) Because of this false premise, pretribulationists have erred in identifying, or including, the Great Tribulation (which is Antichrist’s wrath) with the Day of the Lord (God’s wrath). Similarly, postribulationists have erred in conflating these two events, which is why postribulationists cannot agree among themselves of where to place the Day of the Lord’s wrath.
Prewrath has resolved this misunderstanding by recognizing that the Great Tribulation’s duration is cut short with the Day of the Lord’s wrath to follow afterwards for the remaining duration of the seven years. This motif of deliverance of the righteous and God’s subsequent judgment on the ungodly is a consistent pattern in Scripture so it should not surprise us that this will unfold in like manner at Christ’s Return.
