So let me speak hypothetically here in this post.
If it is written in the Bible, the Old Testament than it will come true. Now whether we have the correct understanding of those verses is debatable, but let's even put that aside for a moment.
Why would God Almighty, Creator of heaven and earth. Of all things, need us, unless He says to do it in scripture, to make His Word a reality?
I would say it may (again I'm treading carefully) be a lack of faith that one would think that we need to do something for God to fulfill His promises. That is to me in essence what you are saying.
If God is not calling us to rebuild the temple, why is man? Faith is that God does what He promises and says. I am not going to doubt God can do anything and that He will call His people if that is what He wants. I don't feel at all called by God to do that though.
Good questions......
Adam and Eve had to make certain choices.......
they made the wrong ones!
Ancient Israel, all 12 tribes were faced with many choices.....
with some notable exceptions they made the wrong ones.
All Messianic Jews, Messianic Gentiles and Christians at this time.....
are being forced to search the scriptures as the Bereans did......
and we also have choices to make.........
.... millions of lives......(frankly... billions of lives).... depend on the choices that we will make in how we
understand the words of the Prophets?!
I could be wrong.....
I have been wrong many many times......
I promoted the "soul sleep" heresy from 1972 or 1973 until 1990 and
read the near death experience account of Dr. George Ritchie......
.... so I could be incorrect on this as well..... but basically......
if we Messianic Gentiles and Messianic Jews and Christians decide to
back up the Orthodox Jewish community in their desire to literally fulfill Ezekiel 40 -48
and if we do so in time for the Jerusalem Third Temple to be operation for the year 2030..... the 2000 year anniversary of the death, burial and resurrection of Messiah Yeshua - Jesus..... then I suspect strongly that .......
the year 2072.... will come with a billion or more healthy human beings alive and well.......
in comparison to the potential time line......
that depends on our choices.......
with the Jerusalem Third Temple operational by 2070... the two thousand year anniversary of the destruction of the Temple of Herod.........
