In one breath, God said both, "Guard and remember the Shabbat." Love of God, time with family, reconnecting with friends and with oneself -- all these fulfill the commandment to "remember" Shabbat.But these beautiful concepts must also be grounded in a foundation of strength, a structure that will provide the soil in which these ideas can take hold, root and blossom.On Shabbat we also strive to bring God's presence into this world.
(For example, "A framed picture falls from the wall. ") However, there are very basic areas of law that deal with action, or refraining from action, that occur on an average Shabbat (assuming you are not marooned on a desert island, or on a ship at sea).We are not allowed to apply heat to things in order to change them in any way.Loaves of bread were formed and baked for the Mishkan; thus we refrain from any sort of cooking on Shabbat.Our tradition tells us that through understanding the Mishkan, we will understand Shabbat.This was to be the central dwelling place of God's presence. Any activity used in forming this house of the Creator would be considered acts of creation.
