I am going to simplify this for you. Jesus commands us to,
"Watch therefore: for ye know not what hour your Lord doth come."
Jesus also commands us to be ready when He said,
"Therefore be ye also ready: for in such an hour as ye think not the Son of man cometh"
Well, this cannot be true for you if you are expecting the Lord to come in an hour you are expecting - which is after the Judgment seals have passed (Which should be easy for anyone to spot).
Paul outright states the rapture happens after the second coming and after the resurrection and we know both of those happen after the tribulation so a pre-trib rapture is scripturally impossible else Paul is a false prophet.
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.
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
A rapture before the tribulation is impossible according to Mat 24:29-30, and a rapture before the second coming is impossible according to 1Th 4:13-17.
So, the proper order of events according to scripture including Mat_24:29:
1. the great tribulation ends. (Mat_24:29)
2. the second coming begins/Christ leaves heaven. (1Th 4:16, Mat_24:30)
3. the resurrection. (dead saints resurrect bodily in heaven and follow Christ as he returns to the Earth-second coming) (1Th 4:14-16)
4. 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)
Your point about us not knowing the hour is meaningless because we know the season, even the day of his return when certain events take place.
Paul even wrote that the second coming will not happen until certain things happen:
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.
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.
2Th 2:5 Remember ye not, that, when I was yet with you, I told you these things?
2Th 2:6 And now ye know what withholdeth that he might be revealed in his time.
2Th 2:7 For the mystery of iniquity doth already work: only he who now letteth will let, until he be taken out of the way.
2Th 2:8 And then shall that Wicked be revealed, whom the Lord shall consume with the spirit of his mouth, and shall destroy with the brightness of his coming:
That's the Antichrist and he does in the tribulation and how the second coming destroys him. This is Paul's anti pretrib teaching. The pre-trib doctrine came about from misunderstanding Paul's first letter so he wrote this second letter to admonish them.
