For 6 days, God created something out of nothing. On the 7th, God created nothing out of something. The world will not relinquish its pace and society will not create the day for us. We must make the concisous choice to obey God, and "observe the sabbath and keep it holy." Sabbath keeping isn't about Law, it's about grabbing onto the robe of the maker of the universe and not letting go!
