Part of the reason we take a day of rest is not just to recharge ourselves, but to remind ourselves that the world keeps spinning even when we take a day off. We aren't as important as we think we are. And God is still in control.
From The Message: "The promise of 'arrival' and 'rest' is still there for God’s people. God himself is at rest. And at the end of the journey we’ll surely rest with God. So let’s keep at it and eventually arrive at the place of rest, not drop out through some sort of disobedience."
