Why is the Sabbath that Jesus mentioned relevant for the end times (at least for the futurist like me

)?
1. There will be a nation of Israel. Oh wait, that already happened.
2. There will be daily sacrifices (The abomination of desolation will stop the daily sacrifice)
3. There will be a temple (otherwise not possible sacrifices)
4. There will be Sabbath keeping
5. There will be false Christs (the Jewish still await a Messiah that will build the temple or will show up when the temple is built)
All of it tells me clearly that there will be a Jewish tradition revival at Jerusalem before the end comes.
