James Bryan Smith’s The Good and Beautiful God begins with a surprising soul training exercise (or spiritual discipline): sleep.
Back in 2009, I found myself in a seminar with Smith during a Renovare’ conference in San Antonio. Jim told us, “Tonight, when you go to your hotel, I want you to pray the 23rd psalm as you fall asleep. Don’t set an alarm. Sleep until you wake up, even if that results in your being late to our morning session.”
Sleep is a Need, Not a Luxury
When we’re sleep deprived, our lives don’t work right. Sleep deprivation has physical effects. And those physical effects have emotional, intellectual, social, and spiritual consequences. The various dimensions of the human person are connected.
In The Organized Mind, Daniel Levitin writes:
At one time or another, you’ve probably thought that if only you could sleep less, you’d get so much more done. Or that you could just borrow time by sleeping one hour less tonight and one more hour tomorrow night. As enticing as these may seem, they’re not borne out by research. Sleep is among the most critical factors for peak performance, memory, productivity, immune function, and mood regulation. Even a mild sleep reduction or a departure from a set sleep routine (for example going to be late one night, sleeping in the next morning) can produce detrimental effects on cognitive performance for many days afterward. When professional basketball players got ten hours of sleep a night, their performance improved dramatically: Free-throw and three-point shooting each improved by 9%.p. 189, emphasis mine
Levitin’s book is focused on brain science and how we deal with information overload. A big way we can help our brains keep things straight is by organizing our time, activity, and environment in ways that support cognitive well-being. This includes how we schedule sleep.
Regular Sleep is Good Stewardship
The implications for the spiritual life are plain. Jim Smith is right: sleep is cornerstone exercise for the training of the soul. As human beings we are finite and limited. But God is not. Each time we lay down to rest, we trust God to care for us and watch over us during the night. We also trust, and welcome, that moment when God raises us up for another day to serve, to grow, and to walk in relationship with God and others.
