Do you believe He is sovereign--that He rules over every detail of your life? It seems to me there is no place quite as restful. To trust that this God--this God who is love, is faithful, is merciful, is gracious--reigns supreme over every detail of our lives; is there a place of greater rest? Believing that even His allowances of difficulty in the lives of those who love Him have been with glorified purpose rather than thinking we live at the mercy of cellular deterioration or moral failure. Rest there.
"Are not two sparrows sold for a copper coin? And not one of them falls to the ground apart from your Father's will...(yet) you are if more value than many sparrows." (Matthew 10:29, 31) He reigns in love. Here is His promise: cry out to Him and He will lavish Himself upon you; delve into His Word and ask Him to make it alive in your spirit. But take cover, your brain may explode.
