I respectfully disagree, though I do agree in the sense that this tribulation included Christian persecution. It's just that I think Jesus was speaking of Jewish Christians who would be persecuted initially.Contextually the great trib Christ spoke of was a time of persecution of Christians during the same time the Beast would reign (usually called the AC). It was never a Jewish tribulation (Judaism).
I don't see how anybody can get around Jesus identifying this "great tribulation" with the Jewish People. I've quoted it a hundred times:
Luke 21.20 “When you see Jerusalem being surrounded by armies, you will know that its desolation is near. 21 Then let those who are in Judea flee to the mountains, let those in the city get out, and let those in the country not enter the city. 22 For this is the time of punishment in fulfillment of all that has been written. 23 How dreadful it will be in those days for pregnant women and nursing mothers! There will be great distress in the land and wrath against this people. 24 They will fall by the sword and will be taken as prisoners to all the nations. Jerusalem will be trampled on by the Gentiles until the times of the Gentiles are fulfilled."
When Jesus spoke of the "times of the Gentiles" he was speaking to Jewish believers. He was not speaking to Gentiles about Gentiles!
The whole reason Jesus indicated God's wrath was coming down upon Israel was because they were rejecting their own Messiah. In rejecting Christ they were rejecting Christians too!
So yes, this involves Christians being persecuted. But the emphasis is on God's judgment against unbelieving Jews who were rejecting their Messiah. They would lose their temple and their holy city. And they would lose their land going into an age-long Diaspora. That is just what the passage says!
This made it even more difficult for believing Jews because not only would they be persecuted by the unbelieving majority in Israel, but they would suffer the loss of their land along with their unbelieving compatriots who brought all this judgment down upon them.
