I used to apologize, almost reflexively, whenever I admitted to anyone that I had spent an afternoon resting instead of producing something — as though rest needed to be earned or defended, rather than simply practiced.
God rested on the seventh day not because He was tired, but because rest itself was built into the fabric of creation as something holy (Genesis 2:2-3). The Sabbath command in Exodus is not a suggestion for the overworked; it is a command for everyone, including those of us convinced our particular responsibilities are too important to pause. I have stopped apologizing for rest because I finally understood it is not a break from obedience. In a very real sense, it is obedience.
