In some ways, the whole point of the Exodus was Sabbath. Let my people go, became God’s rallying cry, that they might worship me. At the heart of liberty – of being let go – is worship. But at the heart of worship is rest-a stopping from all work, all worry, all scheming, all fleeing-to stand amazed and thankful before God and his work. There can be no real worship without true rest.
Mark Buchanan, The Rest of God, p.94
