The mountain conversation in Matthew 17 already points past the buildings.
A temple is holy because God assigns presence there. When presence moves to the Son, the building’s role is finished even before the stones fall.
Matthew 17’s tax, Matthew 21’s cleansing, Matthew 23’s desolate house, and Matthew 24’s not-one-stone form one argument.
AD 70 is the public funeral of a system Jesus had already pronounced finished.
You do not commute to a building God already left. The dwelling is with His people in the Son.
