Theology of Sleep

Fred Sanders recently wrote about a Theology of Sleep. Here's the conclusion:

At the very least, sleep is a good opportunity to entrust yourself, your entire self, to God’s care. You’re trusting something when you lay down your body and, with it, the control of your conscious mind. That moment when you consciously choose unconsciousness, and let yourself go, is a daily opportunity to relinquish control to a God who you have to trust.

Sleep is good practice for death. It’s good preparation for life with that same God who you’re going to have to trust eventually. And it’s worth asking for sweet dreams, because he gives sleep to his beloved, and he gives to his beloved in their sleep.
