“Those of us who have come to make regular use of prayer would no more do without it then we would refuse air, food, or sunshine. And for the same reason. When we refuse air, light, or food, the body suffers. And when we turn away from meditation and prayer, we likewise deprive our minds, our emotions, and our intuitions of vitally needed support. As the body can fail its purpose for lack of nourishment, so can the soul. We all need the light of God’s reality, the nourishment of His strength, and the atmosphere of His grace. To an amazing extent the facts of A.A. life confirms this ageless truth.”
