Shabbat
In Jewish law, Shabbat is the most important Jewish holiday. It is even more important than Passover, Rosh Hashanah and Yom Kippur.  Jewish mystics say that the Shabbat day is meant to be like a perfect world. In this world, everyone knows about God and loves him.  They believe that kind of world has not been seen since the Garden of Eden, and will not be seen again until the Messiah comes.
