the Great Tribulation

“the Great Tribulation”
The Great Tribulation will be a time of distress, and persecution, and trouble in the whole world. A time of the greatest distress that the world has ever known, because the antichrist will hold sway the whole world politically, religiously and economically in 3 ½ years or forty-two months shortly after the Rapture.

Christ Jesus has promised that His saints who keep His Word—those who keep His Command to endure patiently, He will keep from “the hour of trial” which is coming on the whole world.
"Because you have patiently obeyed Me despite the persecution, therefore I will protect you from the time of Great Tribulation and temptation, which will come upon the world to test everyone alive.
Rev 3:10-11 TLB

Here, The Lord speaks of "the Rapture saints,"—"the Bride of Christ." He will protect His ‘Called-Out-Church’—‘the sheep of His pasture,’ from the greatest distress in the world. He will do this because she patiently obeyed Him despite the persecution in the Church Era.

But, on the other hand, "the tribulation saints" are those who will go through the Great Tribulation, and be victorious.
The tribulation saints were recorded to be victorious over:
1.) the beast,
2.) and over his image,
3.) and over his mark,
4.) and over the number of his name
See Revelation 15:2.

“Those destined to go into captivity” will worship the beast, in the time of “the Great Tribulation.”
“The tribulation saints” left behind, will endure, and be patient, and faithful to suffer it.

All inhabitants of the earth will worship the beast — all whose names have not been written in the Book of Life belonging to The Lamb that was slain from the creation of the world.

He who has an ear, let him hear.
If anyone is to go into captivity, into captivity he will go.
If anyone is to be killed with the sword, with the sword he will be killed.
This calls for patient endurance and faithfulness on the part of the saints.
Rev 13:8-10 NIV

Jesus is crying so much now because, He has to use the adversary of His people in "the New World Order to purge the saints that will be left behind in "the Great Tribulation."

He says My divine Protection is about to be removed from this earth!
