The Great tribulation of Matthew 24 is over and done with.
Here is something I picked up.
THE GREAT TRIBULATION — FUTURE OR FULFILLED?
Matthew: “For then shall be great tribulation, such as was not since the beginning of the world to this time, no, nor ever shall be. And except those days should be shortened, there should no flesh be saved: but for the elect’s sake those days shall be shortened” (24:21, 22).
Mark: “For in those days shall be affliction, such as was not from the beginning of the creation which God created unto this time, neither shall be. And except that the Lord had shortened those days, no flesh should be saved: but for the elect’s sake, whom he hath chosen, he hath shortened the days” (13:19, 20).
Luke: “For these be the days of vengeance, that all things which are written may be fulfilled . . . for there shall be great distress in the land, and wrath upon this people. And they shall fall by the edge of the sword, and shall be led away captive into all nations: and Jerusalem shall be trodden down of the Gentiles” (21:22-24).
Unless we completely ignore the setting, it is evident that the tribulation mentioned here is that which was to come upon the people of Jerusalem and Judea — tribulation which would result in the destruction of the city and temple. As we have seen, Jesus spoke of various things that would come to pass first — wars, famines, pestilences, earthquakes, etc. None of these would be the sign of the impending desolation. But when they would see Jerusalem compassed with armies, then they would know that the desolation was nigh, and they should flee into the mountains. Why? “For then shall be GREAT TRIBULATION”, wrote Matthew. Luke’s account says: “For then shall be GREAT DISTRESS in the land [Judea], and wrath upon this people [the Jews]. And they shall fall by the edge of the sword, and shall be led away captive into all nations: and Jerusalem shall be trodden down of the Gentiles.”
According to the scriptures, the “great tribulation” of which Christ spoke was to bring great affliction, distress, and wrath upon the Jews and destruction upon their city and temple."
Notice that the Jews surviving the onslaught would be shipped off to all nations. That is history; post-tribulation history.
