"Have courage for the great sorrows of life and patience for the small ones. And when you have laboriously accomplised your daily task, go to sleep in peace. God is awake." (Victor Hugo, 1802-1885)
In the Bible, sleep is both a metaphor for, and indicator of, true faith. In Psalm 127, the LORD gives sleep (faith) to one tempted to build his house by sheer human effort. In Psalm 3, King David recounts his flight from Absalom and how, when he found himself surrounded by a murderous horde, laid himself down and took a little nap!
We are most vunerable and least "productive" when we're asleep. And yet the faithful sleep soundly, confident that the One building their houses and guarding their loved ones "never slumbers nor sleeps." In contrast, the faithless stay up way too late, and when they do finally fall into bed exhausted, they toss and turn worried about all that didn't get done during the day, revising mental lists, vowing to do better, adjusting their agendas, and fretting over how to protect their homes from harm.
Hugo is right. When it's time to work, work hard. But at the end of the day (and perhaps even for a few minutes after lunch) "...go to sleep in peace. God is awake." For, as the author of Hebrews noted, "without faith it is impossible to please Him [God]." Really. So scoot. Off you go now. And don't forget to brush your teeth...
I promise the earth will keep spinning, even without your willing it to do so! Scout's honor.
