The Biblical Restoration of Israel

I know that Israel simply does not figure in the hearts and minds of most Christians across the whole Body of Christ.

Neither does Judah hold any interest in these same minds.

Could Biblical Judaism have been hijacked and given another name and tiltle?  Could that be Christianity?

After all, nowhere does Yeshua ever claim to bring a new belief system or more importantly a new belief structure.

Judaism? Is this purely a Jewish themed religion?

Only if the Tanach or Old Testament means nothing!
