"I will both lay me down in peace, and sleep: for thou, LORD, only makest me dwell in safety. Psalms 4:8"
Natural sleep has been created by GOD to give rest to the human body and rejuvenate it. Good natural sleep is given to the children of God so that they can wake up with renewed energy and a refreshed body to carry out the will/purpose of God for the day.
If you are denied a good natural sleep, you are likely to have a rough day and your body, especially your brain, will not give you the accurate results that it usually gives you. Good natural sleep is attained in an atmosphere of good security.
The Psalmist enjoyed good natural sleep because the LORD provided him with a secure atmosphere for a good sleep. Children of God should make time for themselves to have good sleep: they should not be afraid whatsoever, because GOD is with them and ready to provide them with that atmosphere of security.
Hallelujah!
Dearly beloved, do you enjoy good natural sleep?
