To Jews and Christians mostly but others are free to poke their noses in....
What is the Messiah meant to do, according to Tanakh?
No 'NT' quotes thanks.
I've tried this thread before, I'm bored, so I'm trying it again.
Based on the Jewish belief:
The messiah, will be a leader that will be smart and articulate and will lead the entire world leadership to a new era.
Not a spiritual era in the sense of heaven and all that, rather an era of peace and prosperity based on the original way of life humans were meant to live.
It is said: "ועולם כמנהגו נוהג"... This means that nothing will actually change in the world until this leader will "rise to power", and even after, the only thing that will change will be our way of understanding reality.
It is claimed that there are two possible events that will precede his coming:
Either a sort of a world war will occur (גוג ומגוג) that will be so brutal that it will render our world to near oblivion. This war will continue until this leader will arrive and lead humanity to peace and prosperity as a whole (not any specific country or religion).
The second possible event will be that humans will advance more on their own and this leader will come even sooner.
These are called : בעיתו או אחישנה
Meaning in his time or sooner.
It depends on the status humans will be at.
Besides that, it is claimed that Jerusalem will be the capital of the entire world, not is a sense of the entire world will be one country, rather that it will be the center of leadership for the entire world (kind of a "white house" of the world).
The third temple house will be built for all humans to enjoy.
Religions will be rendered irrelevant as the truth will be revealed and all will know God.
Some claim there will be a sort of resurrection, although it is not written per say in the bible, rather that people will be able to communicate with their lost loved ones.
There are many more details, but these are the core ideas.
It is very interesting, btw, to see, that technology slowly advances to a point where all these ideas become more and more probable.
Unlike what many think, the Jewish bible doesn't speak of any after life or spiritual worlds when the messiah arrives, rather a change in the energy of humanity (we will evolve to a "female energy" from "male energy"). This is also interesting that the recent developments in our society follows such a trend also.
Please note this is only the tip of the iceberg
there are many other things that are predicted in the OT regarding the "After the days" (this is the Jewish name of the days of the messiah).
