If God gives those He loves sleep, then sleep must be a gift of God. I am talking about actual sleep, not just rest. Rest is good but it's not sleep.
 
Sleep heals! Sleep heals the mind and emotions as well as the body. One renowned doctor, who was a specialist in at least three areas of medicine, told me that during sleep the immune system renews itself. As I write this I can't help but to think of my uncle. He was a brilliant doctor. One time when I was a boy he told me that he didn't believe in sleeping eight hours a night because if you did that you slept one third of your life away. I remember being impressed with that statement. My uncle would sleep from about midnight until 4 or 5 in the morning. After years and years of that, while he was still in his 50's he was diagnosed with Multiple Sclerosis. He spent the last 20 years of his life in a nursing home due to the disease. He is not the only person I have known to come down with a neurological disorder due to a life of insufficient sleep.
 
Sleep must be vital because Satan fights it so. Do you realize how many people can't sleep?  People who have trouble sleeping need to memorize and claim this promise from God in Psalm 127:2 each night in prayer.
 
You can do as much damage to your body and life span by not sleeping, as you can by eating junk food and being a couch potato.
 
If God gives His beloved sleep, then sleep must be good, and not sleeping must be bad.
 
Sleep - enjoy it. It's a healing gift to you from God!
