1 Concerning the coming of our Lord Jesus Christ and our being gathered to him,
These are two things, the Lord’s coming and our being gathered to Him, what we refer to as the rapture. It appears that the Lord comes secretly immediately before the rapture.
we ask you, brothers and sisters, 2 not to become easily unsettled or alarmed by the teaching allegedly from us—whether by a prophecy or by word of mouth or by letter—asserting that the day of the Lord has already come. 3 Don’t let anyone deceive you in any way, for that day will not come until the rebellion occurs and the man of lawlessness is revealed, the man doomed to destruction.
Everyone should be very clear that a rebellion occurs first and the man of lawlessness is revealed. There has been some wonderful exposition of Isaiah that the US is the transplanted vineyard of the Lord, the vineyard He surrounded with hedges to the East across the sea. Some have even overlaid the pattern of the temple and the items in the temple over the US and the pattern is quite fascinating. So let’s look a little closer at this, the antichrist who is to come, the “man of lawlessness” will be “impudent and brazen”. To a lesser degree we saw this with Hitler, but it will be on full display with the man of lawlessness. Second, he will be a master of intrigue. You would have to be to make a puppet president that you control from behind the scenes. But then Daniel says that he will destroy the mighty but not of his own power. The antichrist is used to destroy Jezebel. She was the wife of the King, if we were to use a modern example she is the first lady, or you could say she is the VP or even you could say she is the "speaker of the House" as most people will say the wife is in charge of the house. That is the rebellion that must take place first, it was Jezebel’s corruption that the Lord is going to judge. The antichrist destroys the mighty, destroys Jezebel and all of her confederates, but not of his own power. This is weird, one would think that Antichrist and Jezebel are on the same team, but this is a team where the protege eats the mentor. Just like what we saw happen to Cuomo. It will be the Lord Jesus with his saints as His army. They are the ones who are restraining the evil Jezebel. According to the type she hired 400 prophets of Baal, she controlled the media. Meanwhile a hundred prophets of the Lord were hidden in a cave. So it is the Lord that destroys Jezebel, but it is the antichrist who takes credit for it and as this unfolds he is revealed. The way I see it he destroys her because it is expedient.
4 He will oppose and will exalt himself over everything that is called God or is worshiped, so that he sets himself up in God’s temple, proclaiming himself to be God.
We just shifted from past tense to future tense. Before the day comes the rebellion takes place and the man of lawlessness is revealed. That takes place before we are gathered to the Lord, i.e. raptured. But in the future, after the rapture, He will oppose and will exalt himself over everything that is called God or is worshipped. It does not say that he does this prior to the rapture. That is not how he is revealed. He is revealed because he is uniquely impudent and brazen, because he is a master of intrigue, because he destroys the mighty, and finally, because he receives a head wound and is resuscitated, allowing an evil spirit to enter into him. However, after he is inhabited by that evil spirit he will oppose God, even setting himself up in the temple and proclaiming himself to be God. He doesn’t destroy the mighty with his own power, but he does take full credit for it.
So there is a falling away, a rebellion among Christians with an apostasy, but there is also a rebellion that is more "political". Antichrist is very satanic, but that is not revealed until after the rapture, prior to the rapture he may come across as a great guy, in fact the verse "when they say peace and security" suggests that when he comes to power initially the whole world thinks and proclaims "peace and security". Who knows how they would do it, maybe he gets a Nobel Peace prize just for being him. But then there is sudden destruction, he is a master of intrigue, manipulating some feeble president from behind the scenes. What is sudden destruction? Maybe this feeble president just starts rubber stamping executive orders like it is some kind of cartoon. Wouldn't be surprised if he started on day 1, that would be "sudden".
