The number one enemy of Christian spiritual formation today is exhaustion. We are living beyond our means, both financially and physically... According to numerous studies, the average person needs approximately eight hours of sleep in order to maintain health. This tells me that God has designed humanity to spend nearly one-third of our lives sleeping. This is a stunning thought. We were made to spend a large portion of our existence essentially doing nothing...

Sleep is a perfect example of the combination of discipline and grace. You cannot make yourself sleep. You cannot force your body to sleep. Sleep is an act of surrender. It is a declaration of trust. It is admitting that we are not God (who never sleeps), and that is good news.
