Maybe, as part of our spiritual practice, it would be worthwhile to examine our attitude toward sleep:
During the hours of my sleep how will God prepare to use my obedience, service and speech when morning breaks? I go to sleep to get out of the way for awhile. I get into the rhythm of salvation. While we sleep great and marvelous things are happening, things far beyond our ability to create. Then when we rise, our work can settle into the context of God’s work. Our human work can be integrated into God’s holy work.
