Why?
I would think the burden of proof rests with those that claim a prophecy has already been fulfilled. After all, there ought to be a record in history if it has.
Because none of these things are mentioned in the NT as being far in the future. The apostles knew nothing of Israel or Egypt in the 21st century, or spoke of the OT prophecies as yet to be fulfilled. Not a single one. Why are futurists smarter than the apostles? That’s what needs to be proved.
