The Jews are the world's conscience. No one likes a conscience. I went to Sunday school and hated it. Kids love candy, but most gourmet pleasures are acquired tastes. This is true of wine, cheese, cigars, and coffee.
Wisdom is an acquired taste.
The Messiah will be a human being descended from King David. He will unite the Jewish People and lead them back to their relationship with God and Torah. When that occurs, the nations of the world will also acknowledge the truth of God's Law, and then the world will live in peace. The Bible gives Jews 613 commandments, relating to the sanctification of every aspect of life. Judaism isn't a closed club of gender or of race.
