The world of Moshiach

The Rambam closes the Mishneh Torah with a vision of the days of Moshiach: there will be no famine and no war, no jealousy and no rivalry, for good things will be as plentiful as dust. The whole world will have one occupation, to know Hashem. The Jewish people will be great sages, understanding hidden matters, and the earth will be filled with knowledge of Hashem as the waters cover the sea.
