Whatever we do for the love of God benefits our souls and our lives in a way that ego-motivated actions never can. Whatever we do for the love of God is done with sincerity because it is not motivated by self-interest. We leave our concern for gain and loss, success and failure, in the hands of God. We stop considering ourselves as the sole cause of our actions and their results. Consequently, we become the instruments of a deep wisdom and love.
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. They were meant to communicate the insight that interrupting the ceaseless round of striving requires a surprisingly strenuous act of will, one that has to be bolstered by habit as well as by social sanction.
