Post the scripture please.
Because I know this can't be....
The idea of a pretrib rapture took place back in Paul's day due to people misunderstanding something he said.
1Th 5:1 But of the times and the seasons, brethren, ye have no need that I write unto you.
He shouldn't even have to speak of these things because he would have told them in person when he was with them but for some reason he decides in fact to re-tell them this:
1Th 5:2 For yourselves know perfectly that
the day of the Lord so cometh as a thief in the night.
This is it. The idea that Christ could come suddenly without any warning before the tribulation and Antichrist etc is what started the Pre-trib concept. This one sentence will be misunderstood and the idea that Christ could come at any time, even before the tribulation happens, is born. The facts are that Christ cannot and will not just suddenly appear because there are major events that have to take place first before he arrives but those who are unsaved and spiritually blind won't know this and so the second coming will surprise them without warning as a thief in the night but not those who are awake and watching for the right signs.
1Th 5:3 For when they shall say, Peace and safety; then sudden destruction cometh upon them, as travail upon a woman with child; and they shall not escape.
1Th 5:4
But ye, brethren, are not in darkness, that that day should overtake you as a thief.
And this is the part that was missed or ignored. Christ only comes suddenly, without any warning
to those who are deceived, in darkness, and are worshiping a false god in the tribulation. Christ's actual appearance will be sudden and shocking to them! But not to us!
1Th 5:5 Ye are all the children of light, and the children of the day: we are not of the night, nor of darkness.
1Th 5:6 Therefore let us not sleep, as do others;
but let us watch and be sober.
1Th 5:7 For they that sleep sleep in the night; and they that be drunken are drunken in the night
So the confusion about Christ appearing suddenly at any moment reached Paul and he wrote a second letter to explain what he meant in the first one!
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 at any moment instead of after the tribulation as Christ said in the gospels.
