My guess is that the temple will be rebuilt sometime about when warp drive is developed. Star Trek cannon has it that the Warp Drive was developed in 2063. So sometime about then. 2063 also roughly coincides with with the date that Issac Newton put for the end of the world. https://www.openculture.com/2015/10/in-1704-isaac-newton-predicts-the-world-will-end-in-2060.html

Indeed it will.
At least in time for Satan’s anti-messiah to declare himself to be “God”; just as prophesied.
