So, what you're saying is PreWrath is legit?
Since I disgree MUCH with keras, I want to answer your question.
Is "prewrath" legit? If someone said, "the rapture of the church will be before God's wrath" I would agree, 100%. God is not going to set any appointments for us with His wrath.
The great crowd John saw in heaven, in Rev. 7, is the just raptured church. The church will be taken out a moment before the Day of the Lord begins. That is what Paul teaches us in 1 Thes. 5, and what John shows us in Revelation.
HOWEVER: the "standardized" "prewrath" theory started by Rosenthal and Van Kampen is 99% BOGUS. Their theory which has become very popular and called "prewrath" is just plain WRONG. These two men started off on the wrong foot, and ended up miles from the intent of the scriptures.
One day Van Kampen called Rosenthal and said, "I FOUND IT!" His meaning, he found this "key" that believers had missed for centuries: the key to when the rapture would be.
So what was it he found? He read in Matthew 24 that the signs in the sun and moon would come AFTER the "tribulation." He read in Joel 2 that the signs in the sun and moon would be BEFORE the Day of the Lord. Therefore, in his (Van Kampen's) mind, the correct order would be tribulation first, then signs in the sun and moon, then the rapture, then Day of the Lord.
Is this really what the word of God tells us? No, they started off with error, and ended up with GROSS error.
The TRUTH? Indeed, just as Joel tells us, there WILL BE signs in the sun and moon - the moon turning blood red - meaning a moon that is SEEN. And this is the sign for the Day of the Lord. It begins just as John shows us, at the 6th seal. (Note carefully that the 6th seal comes before the 7th, and that the trumpet judgments follow the 7 seals and that the vials come after the 7 trumpets.)
John's order or chronology is perfect as written and needs no rearranging. The signs come with the moon appearing blood red. Then THE DAY starts (6th seal) then the 70th week or "the trib" starts at the 7th seal. The trumpets come in the first half of the week, and the 7th trumpet marks the midpoint of the week.
"The tribulation" or the 70th week is covered from chapters 8 through chapters 16 in Revelation, ending with the 7th vial. Yet, for Prewrath, the days of tribulation are forced to be before the 6th seal - or seals 1 through 5! In reality, seals 1 through 5 are church age.
Finally, somewhere in chapter 19, just before Jesus comes, there will be signs in the sun and moon AGAIN (second time) but they will be different: it will be totally dark - neither the sun or moon will be visible! And this will be the sign of HIS COMING to the battle of Armageddon.
Always remember: ANY theory that must rearrange John's God given chronology of Revelation is immediately suspect - and WILL BE proven wrong.
