What Shabbat represents

  In the Torah, God commanded Israel to remember and observe Shabbat. Shabbat is the seventh day of rest [Friday sundown till Saturday sundown] where melacha [usually translated as work; but has a different definition form the secular definition; since melacha means transformative labor, not strenuous labor] is forbidden. The Torah lists 39 melachot as forbidden. But what does Shabbat represent? Clearly, it represents acknowledging God as the ultimate soverign. It acknowedges and solidifies God's dominion over the self. It counters idolatry, since Shabbat is a break from the normal routine. It is to acknowledge the fact that God created the world; since the Torah says that God "rested" on the seventh day; as well as to show that Israel was not enslave like she was in Egypt. Truly, Shabbat can be a challenge to keep. For most of my life so far, I did not keep Shabbat. Now I do [for instance, I used to go on BTR on Shabbat; but a long while ago, I gave up going on BTR on Shabbat].
But nevertheless, it is crucial for the [Jewish] soul and for it to get eternal life. For a Jew, without Shabbat, then there is no real way to connect to God, as it is a crucial componant for the Jewish soul to bring Godliness in themselves. For Shabbat keeps idolatry in check and brings order. For Shabbat was given to Israel in order for there to be order, namely serving God instead of letting the material world or anything else come between Israel's relationship with God.
