“Our patterns of work and rest reveal what we believe to be true about God and ourselves. God alone requires no limits on his activity. To rest is to acknowledge that we humans are limited by design. We are created for rest just as surely as we are created for labor. An inability or unwillingness to cease from our labors is a confession of unbelief, an admission that we view ourselves as creator and sustainer of our own universes (pp. 64-65).”
