(20) “But when you see Jerusalem surrounded by armies, then know that its desolation has come near. (21) Then those who are in Judea must flee to the mountains. Those who are inside the city must depart. Those who are out in the country must not enter it, (22) because these are days of vengeance, to fulfill all that is written. (23) Woe to those who are pregnant and to those who are nursing their babies in those days! For there will be great distress on the earth and wrath against this people. (24) They will fall by the edge of the sword and be led away as captives among all nations. Jerusalem will be trampled down by the Gentiles until the times of the Gentiles are fulfilled. (Luke 21:20–24 NET)
Too many interpreters (preterists, historicists, “near-far,” and even many futurists) have assumed that Luke 21:20–24 describes the destruction of Jerusalem that occurred in AD 70, thus vv. 20–24 should be interpreted in a preterist fashion. I have not been quick to come to that conclusion because that interpretation contains some linguistic and historical difficulties. In the future (no pun intended) I am intending to publish my exegesis on this text showing the plausibility for an exclusively futurist interpretation.
In the meantime, Mike Coldagelli has written an article outlining a futurist case for this text, making some points that need to be considered in the exegesis of this text.
