(Mat 24:2 And He said to them, “Do you not see all these things? Truly I say to you, not one stone here will be left upon another, which will not be torn down.” )
(Mat 24:3 As He was sitting on the Mount of Olives, the disciples came to Him privately, saying, “Tell us, when will these things happen, and what will be the sign of Your coming, and of the end of the age?” )
Look, Jesus associated the destruction of the 1st century temple with his coming after which the disciple asked when shall these things be?
When?
(Mat 24:34 “Truly I say to you, this generation will not pass away until all these things take place. )
The temple was destroyed in the generation that he lived in (this generation) therefor his coming was directly related to the time of the 1st century temple destruction.
A kid could figure this out.
