Why jesus is not the messiah for the jews?

[searchinmyroots]

Water is Torah and Torah is life, which means in my opinion it is how to live your life and get the most out of it as G-d wants us to.

So living water can mean Torah is alive, it is life how to be liven. 

Those verses in Jeremiah seem to say that G-d is the source of Torah that lives and keeps us, how to live your life.

I don't see any correlation to eternal life.
