Trusting God throughout the day allows us to rest peacefully at night. Fear and anxiety are the chief causes of the tension that leads to disturbed rest. And sound rest is an absolute necessity for the renewing of our bodies, minds, and emotions. Only a peaceful relationship with God and with others allows us this total renewal at the close of each day. We must learn to relax and release our cares and burdens to the Lord and then claim His promised rest.
I will lie down and sleep in peace, for You alone, O Lord, make me dwell in safety. (Psalm 4:8)
