I'm not going to leave you hanging brethren that want know what "wrath" Apostle Paul was pointing to in 1 Thessalonians 5. I don't care if those don't read this who love men's word instead of God's Word.
1 Thess 5:1-9
5 But of the times and the seasons, brethren, ye have no need that I write unto you.
2 For yourselves know perfectly that the day of the Lord so cometh as a thief in the night.
Isaiah is one of the major Old Testament Books that mentions the events to happen on that future "day of the Lord". That is about the last day of this world when Lord Jesus returns and ends this present world. Apostle Paul also revealed this in 2 Peter 3:10 about that day.
That "times and the seasons" Paul mentions to them is about the Signs of the end of this world, like that "day of the Lord" when Jesus comes. Those Paul spoke to there already knew those "times and the seasons", so like he said, he had no need to show them. They knew them.
But how strange it is that those on man's fake pre-trib rapture do not... know those "times and the seasons"? And we are in the 21st century and they don't know them! Why? Simply because those deceived brethren are too busy playing church, socializing and partying instead of disciplining theirselves in God's Word with His help. I'm not trying to be mean by saying that, it's simply the truth, even though those lazy brethren are embarrassing to those who have done their homework in God's Word.
Want proof of this? Notice how those on the pre-trib rapture lie go straight... to Paul's 9th verse below about "wrath", and then assign 'their own' timing to it! They do that because that is how the false pre-trib rapture preachers work, they pull out a verse here and verse there, and apply a different meaning to it than what the chapter flow does.
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.
Paul is still linking these events to the "times and the seasons" about the end of this world, and that above is absolutely from the Old Testament prophets like the Book of Isaiah. The "day of the Lord" last day event is to come 'at an instant, suddenly', per the Book of Isaiah. (Go check it out and find that in Isaiah, I'm not going to do your homework for you.)
Notice that "sudden destruction" idea by Paul there? He got that from the Book of Isaiah about God's destruction upon the wicked on the last day of this present world. Not only that, but Paul is even giving more... info about that future event. Paul tells us when they, meaning the deceived and wicked, say, "Peace and safety", that is when God will bring that "sudden destruction" upon... whom? Upon THEM!
The very end of this world, the "great tribulation" time, is to be a time when all wars and rumors of wars have stopped, and the coming pseudo-Christ will destroy many using the idea of world peace (Daniel 8). That is why 'they' (the deceived and wicked) will be saying that, "Peace and safety".
And THAT... is the "wrath" Apostle Paul was pointing to in this chapter, NOT Satan's wrath for during the "great tribulation", but GOD's WRATH upon them, the deceived and wicked.
4 But ye, brethren, are not in darkness, that that day should overtake you as a thief.
5 Ye are all the children of light, and the children of the day: we are not of the night, nor of darkness.
6 Therefore let us not sleep, as do others; but let us watch and be sober.
Therefore, Paul admonishes us to remain spiritually awake and sober, meaning don't be deceived about the times and the seasons. Learn them, so as to NOT be deceived!
7 For they that sleep sleep in the night; and they that be drunken are drunken in the night.
Who are "they" again? It's those in the above that will be deceived, saying that "Peace and safety". They will think the coming Antichrist is truly God, and come to fix all the world's problems.
8 But let us, who are of the day, be sober, putting on the breastplate of faith and love; and for an helmet, the hope of salvation.
9 For God hath not appointed us to wrath, but to obtain salvation by our Lord Jesus Christ,
KJV
If you remain spiritually awake and sober, understanding the times and the seasons Paul pointed to, then you won't be deceived like those saying, "Peace and safety", and thus GOD's WRATH will not be upon you on that final "day of the Lord" when Jesus comes. It's that simple.
