You may have heard about the giving of the Torah. You know, when G-d brought the Jews to a small mountain, spoke to them, and gave them the 613 commandments. Well, what you may not have heard is that a couple millennia before that event, G-d gave Adam and Noah (who we all come from) seven laws. By keeping these laws, the whole world can live peacefully and make this world a place G-d can call home with the coming of the era of messiah.
