Somehow the blessedness of sleep has escaped us. We fail to experience the Biblical concept of physical and emotional rest. When we are sleeping, the Lord is much awake and in charge. The night shift belongs unto the Lord. And there is a purpose for sleep which we need to understand.
Sleep is an antidote for stress.
In short, most of us experience excess stress. Sleep serves to prevent damage to the heart from excess stress, and to restore our depleted energy. But, since we spend many sleepless nights, this preventative and restorative process is not taking place. Again, Dr. Archibald explains, we go to bed too high on adrenalin. This excess adrenalin, produced in order that we can perform in stressful situations, also prevents us from sleep.
