Your muscles will work with correlation when the peace of God who created them governs their action. Speak to your muscles every day and to your joints and to your nerves, saying, “Fret not thyself.” (Psalm 37: 1) Relax on a couch or bed, think of each important muscle from head to feet, and say to each, “The peace of God is touching you.” Then practice “feeling” that peace throughout your entire body. In due course your muscles and joints will take heed.
