What is the God's purpose of Jews today


I have heard teachings of how Jews that did not believe where the branches that were cut off and cast into the fire.

If this were true, then the Jews should have disappeared from history, as did the Philistines and other tribes from that area?

The Jews are less than 1% of the world’s population but they are involved in almost every major event in history, normally as a persecuted people.

Why is so much Hate directed at such a small group of people?

Could God’s purpose be to show Christians what Community looks like?
