" Sabbath-keeping requires two orientations. One is Godward. The other is timeward. To keep Sabbath well—as both a day and an attitude—we have to think clearly about God and freshly about time. We likely, at some level, need to change our minds about both. Unless we trust God’s sovereignty, we won’t dare risk Sabbath. And unless we receive time as abundance and gift, not as ration and burden, we’ll never develop a capacity to savor Sabbath. "

― Mark Buchanan , The Rest of God: Restoring Your Soul by Restoring Sabbath
