Most people mistakenly believe that all you have to do to stop working is not work. The inventors of the Sabbath understood that it was a much more complicated undertaking. You cannot downshift casually and easily. This is why the Puritan and Jewish Sabbaths were so exactingly intentional. The rules did not exist to torture the faithful.

In all ways peace is good and produces good. It comes forth from "the tree of life -- and the leaves of the tree were for the healing of the nations."
