Any denial that the rapture will take place is a denial of explicitly stated scripture, and is therefore rank unbelief.
But the timing of the rapture is a legitimate subject for discussion. For ALL positions on the timing of the rapture are based on interpretations of various scriptures. There is simply no scripture that explicitly states the timing of this event.
That's incorrect. Paul had heard some people thought the Lord could come at any moment, misunderstanding the coming as a thief in the night, so he specifically teaches in 2 thess against an any moment return which is also against a pre-trib rapture because he teaches the trib must come first before the return of Christ and then the rapture happens:
1Th 4:13 But I would not have you to be ignorant, brethren, concerning them which are asleep, that ye sorrow not, even as others which have no hope.
1Th 4:14 For if we believe that Jesus died and rose again, even so them also which sleep in Jesus will God
bring with him.
Context is the second coming!
1Th 4:15 For this we say unto you by the word of the Lord, that we which are alive and remain unto
the coming of the Lord shall not prevent them which are asleep.
Context is the second coming!
1Th 4:16 For
the Lord himself shall descend from heaven with a shout, with the voice of the archangel, and with the trump of God: and
the dead in Christ shall rise first:
This is the second coming!
1Th 4:17 Then we which are alive and remain shall be
caught up together with them in the clouds, to meet the Lord in the air: and so shall we ever be with the Lord.
This is the rapture! The Greek word for rapture is harpazo and that's the term used by Paul!
So, the proper order of events according to scripture:
1. the second coming begins/Christ leaves heaven. (1Th 4:16) (this doesn't happen until the tribulation has ended, Mat_24:29)
2. the resurrection. (dead saints resurrect bodily in heaven and follow Christ as he returns to the Earth-second coming) (1Th 4:14-16)
3. the rapture. (living saints on Earth are gathered together from where ever they are on the Earth in order to meet Christ in the clouds when he arrives)(1Th 4:17)
This proves the pre-trib (and mid-trib) rapture to be false because the second coming comes after the tribulation not before or during it, Mat 24:29-30
Paul teaching against a pre-second coming and pre-trib rapture:
2Th 2:1 Now we beseech you, brethren, by the coming of our Lord Jesus Christ, and by our gathering together unto him,
2Th 2:2
That ye be not soon shaken in mind, or be troubled, neither by spirit, nor by word, nor by letter as from us, as that the day of Christ is at hand.
He is saying DO NOT BE WORRIED THAT CHRIST CAN JUST SUDDENLY RETURN AND SURPRISE YOU!
Look at his words:
1. by the coming of our Lord Jesus Christ
That is the second coming!
2. and by our gathering together unto him
That is the rapture!
3. that ye be not soon shaken in mind, or be troubled, neither by spirit, nor by word, nor by letter as from us, as that the day of Christ is at hand.
Don't be worried that the second coming and the rapture "is at hand" meaning they could happen right away instead of after the tribulation as Christ said in the gospels.
2Th 2:3 Let no man deceive you by any means: for that day shall not come, except there come a falling away first, and that man of sin be revealed, the son of perdition;
2Th 2:4 Who opposeth and exalteth himself above all that is called God, or that is worshipped; so that he as God sitteth in the temple of God, shewing himself that he is God.
There are major things that happen first which will let the faithful know the return of Christ is soon! That is mainly the Tribulation and Apostasy where essentially the whole world, all religions and even Atheists, will believe in this person who will claim and seem to be God! I believe he will claim to be Jesus Christ leading so many astray.
So Paul has just said don't be worried that the second coming and rapture can happen before the tribulation and the Apostasy led by the Antichrist! IE: a pre-trib rapture is not true, right from the mouth of Paul himself.
2Th 2:5 Remember ye not, that, when I was yet with you, I told you these things?
Now he has to remind them...but some will never let go of this "any moment" doctrine that Christ can return suddenly to "rapture the Church away".
