The chapter on the Sabbath in With Reverence and Awe is worth the price of the entire book.  While I certainly disagree with Hart and Muether’s obvious dislike of Kuyperian Calvinsim (considering myself a thoroughgoing Kuyperian), I can’t help but appreciate the concerns expressed in this chapter.  Here is a great section in which the authors discuss the difference between Sabbath keeping and revivalism.  

God’s intention was to bless his people through the constant and conscientious observation of the day, week after week and year after year.  Believers are sanctified through a lifetime of Sabbath observance.  In other words, the Sabbath is designed to work slowly, quietly, seemingly imperceptively in reorienting believers’ appetites heavenward.  It is not a quick fix, nor is it necessarily a spiritual high.  It is an “outward and ordinary” ordinance (WSC 88), part of the steady and healthy diet of the means of grace. North American Protestants, we have noted, are generally not in sync with this rhythm.  Attracted to the inward and extraordinary, they commonly suffer from spiritual bulimia, binging at big events, then purging, by absenting themselves from God’s prescribed diet.  The problem with the spirituality of  mountaintop experiences is that no one can live on the mountain.  We all have to return to our day jobs.  When people leave the retreat or Bible camp, or even the midweek small group, they discover their life is still the same: jobs are unpleasant, marriages are shaky, sickness and disease afflict.  In contrast, the Sabbath is supposed to be a discipline that provides an oasis in the desert for pilgrims, whose life is marked by suffering.  Unlike the church activities that clutter the rest of the week, the Sabbath is when believers spiritually assemble on Mount Zion to meet with their God, to hear him speak, and to partake spiritually of their Savior’s body and blood.
