After all, that’s what the text says, doesn’t it? Read it for yourself:
The days will come when your enemies will throw up a bank around you and will surround you and will hem you in on all sides . . . (Luke 19:43)
Then, Jesus goes on to speak of the horrors that will follow, and concludes by saying that these things will happen
Because you didn’t know the time of your visitation.
The Magi knew, Joseph of Aramathea knew—and a small number of other believers who studied their Bibles knew. But the populace, as a whole—enmeshed unbelief—did not. So, when the Romans came and destroyed the city, over 1 million residents and visitors perished!
That was in 70AD, as Daniel had clearly predicted (chs. 9, 2, 7)—that it had to happen in the days of Roman ascendency. Those were the “times” referred to.
Now what of the second coming? We are told that it will occur in times of anxiety, fear of wars, uncertainty in the world, etc. and those who have set dates on that basis have failed. Now no one should set dates—Jesus said we won’t know the day or hour.
But we, like those Jews, ought to know the times (season—kind of period) in which it will take place. Are they right in projecting wars and rumors of wars, etc.? Listen to what Paul says,
When they are saying ‘peace and safety’ sudden destruction will come upon them (1 Thess. 5:3)
And this is, he says, what the “times and seasons” of what he has been speaking in chapter 4 will be like (there was no chapter heading between chapter 4-5 when Paul wrote—heading were added years later, and are uninspired. He just went on speaking of the second coming).
So the times and seasons when Jesus will return will be times when the world thinks it “has it made” (saying peace and safety)—not in times of uncertainty, fear of war, etc. How wrong can people be when they don’t read their Bibles?
