The eternity of the Jewish people is truly phenomenal. The story is told of King Louis XIV asking the philosopher Pascal for some proof of a supernatural force in the world. When Mordechai requests that Esther approach the king on behalf of the Jews, she hesitates. For if you persist in keeping silent at a time like this, relief and deliverance will come from some other place, and you and your father's house will perish. That is an absolute promise from the Almighty.
Jewish history is a cycle, spiralling ever upwards, closer to our final redemption.
