Won't that many agree with me, but I'm not going to hide what Lord Jesus actually taught about the "great tribulation" He warned His Church about. The key to this is paying... attention in His Word, and beware of listening to men's doctrines about it. One can buy all sorts of books about it which leave the actual Bible Scripture and speculate way too much, and thusly you will get farther away from what Lord Jesus said.
Christ's Olivet discourse while upon the Mount of Olives with His disciples is the heart of understanding about the tribulation of the last days leading up to His future return. He covered it in Matthew 24, Mark 13, and Luke 21, and all three of those Chapters should be studied together. Matthew 24 and Mark 13 especially parallel the Seals of Revelation 6, so that is also part of His Olivet discourse, the main Signs expanded.
1. Jesus said as long as we hear of wars and rumors of wars, don't be troubled, but the end is not yet. Kingdom against kingdom, nation against nation, famines, pestilences, and earthquakes in various places. This period prior... to the "great tribulation" Jesus called the "beginning of sorrows".
Since He said don't be troubled about the wars and rumors of wars, because the end is not yet, what "end" did He mean? He meant the very end of this world, the "great tribulation" time. So what kind of time is the OPPOSITE of wars and rumors of wars? The opposite of that is a time of PEACE. That is actually what Apostle Paul taught about the very end per 1 Thessalonians 5 when the deceived begin to say, "Peace and safety", and then "sudden destruction" comes upon 'them'. That "sudden destruction" is about God's Wrath poured out on the final day of this world with Christ's coming, that day called "the day of the Lord". That day will end... the "great tribulation" by Satan.
We are also shown in Daniel 8 and Daniel 11 that the "little horn" and "vile person", simple titles for Satan as the final Antichrist, will use 'peace'... to destroy many, and by his policy will cause craft to prosper. This shows the "end" is going to be a time of fake world peace and prosperity for the deceived! not all out chaos and destruction. Even in Revelation 11 about God's two witnesses, they prophesy for the final 1260 days and have the power of plagues upon the earth. Then when they are killed, the nations will send gifts to each other because those two prophets that tormented them are dead. That shows they immediately go back to their fake "Peace and safety". In Revelation 13, it is asked who can make war with the beast? None in that time, because he will control all nations for 42 months as written there.
Thus the "great tribulation" will have two type of effects upon people:
1. for the wicked and deceived, it will be a chicken in every pot for them as they willingly bow to the Antichrist and take his mark, then everything will be provided for them.
2. upon us, a time of suffering. The Antichrist is coming to make war against us, those in Christ, not the deceived and wicked that he already has in his hand. Some of us are to be delivered up give a Testimony for Jesus against the beast, and by that some... of us will be killed. But others among us, not a hair on our head will perish like Jesus also said.
Then immediately after... that tribulation, all peoples on earth will Jesus coming in the clouds with great power and glory, and He will send His angels to gather His faithful Church. The Zechariah 14 Scripture then reveals where His destination will then be, on earth, upon the Mount of Olives where He ascended to Heaven from (per Acts 1). And He brings all His faithful Church there with Him, east of Jerusalem.
