Sabbath as Resistance

God said above all the commandments to remember the Sabbath and that the person who does not keep the Sabbath should be removed from the community or even put to death (Ex 31:12-17). Why is Sabbath so important to God? Why don't we practice Sabbath? How do we start a Sabbath habit in our world today? Many of the thoughts of this sermon came from or were inspired by Sabbath as Resistance by Walter Brueggemann.
