Sorry brethren, but all this chaos and desolations for the coming "great tribulation" is NOT what is actually written in God's Word about that future time. Instead what is written about is, that it will be a time of world peace and prosperity, not all out war, chaos, and madness.
Matt 24:6
6 And ye shall hear of wars and rumours of wars: see that ye be not troubled: for all these things must come to pass, but the end is not yet.
KJV
Not many preachers finish what Jesus said above about the end. By that, Jesus showed that as long as we hear of wars and rumors of wars, the end is not yet. What "end"? The actual great tribulation time He later warns of. What's the opposite of a time of wars and rumors of wars? Easy. It's a time of peace. That... is kind of time the "end" is going to be about, a time of world peace.
Dan 8:23-25
23 And in the latter time of their kingdom, when the transgressors are come to the full, a king of fierce countenance, and understanding dark sentences, shall stand up.
24 And his power shall be mighty, but not by his own power: and he shall destroy wonderfully, and shall prosper, and practise, and shall destroy the mighty and the holy people.
25 And through his policy also he shall cause craft to prosper in his hand; and he shall magnify himself in his heart, and by peace shall destroy many: he shall also stand up against the Prince of princes; but he shall be broken without hand.
KJV
That is about the coming pseudo-Christ that comes first, working the great signs and wonders Lord Jesus forewarned us about in His Olivet discourse. Notice that it is using peace and craft prosperity in his hand to deceive many for the end. The Revelation 13:4-8 Scripture reveals all the world will worship the "dragon", except Christ's elect (because we won't bow in worship to him).
Thus the "great tribulation" time is going to be a time of WORLD PEACE AND SAFETY, for the DECEIVED. And that will be the MAJORITY OF PEOPLES ON THE EARTH.
In 1 Thessalonians 5, we find Apostle Paul warning us about that "Peace and safety" time also. He showed that when 'they' say, "Peace and safety", then... shall "sudden destruction" come upon 'them'. Paul was pointing to the destruction of the 7th Vial on the final day of this world when Jesus comes, on the "day of the Lord". So just prior to that final day of this world, the majority of the world will be saying, "Peace and safety" because of the pseudo-Christ having offered to pay off all their debts and woes, and establish world peace upon the earth.
But... that false messiah will be looking for those of us faithful in Christ's Church, to try and destroy us, because we already know that pseudo-Christ that comes first will be an imposter.
Thus the great tribulation will have effect 2 ways:
1. as a time of great deception upon the deceived who will think God has actually returned, and takes care of all their problems, and that Christ's Kingdom has final come.
2. as a time of persecution upon Christ's saints that only listen to Him.
