It's Jesus' response to the disciples request: "
Tell us, when will these things be?" (mat 24:3) which the disciples asked because He said of the temple; "
Assuredly, I say to you, not one stone shall be left here upon another, that shall not be thrown down."
That is exactly what Titus did.
So it fits that portion of Jesus' teaching.
It does not address His coming or the end of the age which were the other two questions the disciples asked.
Mat 24:3 Now as He sat on the Mount of Olives, the disciples came to Him privately, saying,
“
Tell us, when will these things be? (question number one)
And what will be the sign of Your coming, (question number two)
and of the end of the age?” (question number three)
In any attempt to understand Jesus response, it is necessary to recognize that He is addressing three separate topics: (1) the destruction of the temple, (2) His second coming, and (3) the end of the age.
Conflating these three topics will lead to some false conclusions.
Also, Jesus' answer is not that easy to unravel. It is to some extent difficult to tell what part of His answer to apply to which question.
It's also fertile ground for all kinds of speculation and esoteric deep meanings, if one is so inclined. (If you're preaching on this passage, be sure to bring you power-point charts and illustrations. :wink)
