The physical structure wasn’t rebuilt after the Romans destroyed it in 70 AD.
Obviously, Jesus rose and later ascended into Heaven, but that is not the context of the passage. Rather, Jesus foretells the destruction. Imagine if somebody told you 40 years before the statue of Liberty was going to be destroyed? And then it happened. The Temple, like the Statue of Liberty, bear cultural significance. It would be shocking.
In other words, really bad things are going to happen.
“The physical structure wasn’t rebuilt after the Romans destroyed it in 70 AD.”
Oh but it will be!
Daniel 9:27 King James Version (KJV)
27 And he shall confirm the covenant with many for one week: and in the midst of the week he shall cause the sacrifice and the oblation to cease, and for the overspreading of abominations he shall make it desolate, even until the consummation, and that determined shall be poured upon the desolate.
Matt 24:15
Mark 13:14
2 Thessalonians 2:4 King James Version (KJV)
4 Who opposeth and exalteth himself above all that is called God, or that is worshipped; so that he as God sitteth in the temple of God, shewing himself that he is God.
