Dr. Backus banyak berkecimpung dalam praktek kesehatan profesional. Beliau memaparkan keseimbangan Alkitab dan pemikiran manusia yang terkadang rancu di kalangan umat Kristiani.
Recent studies confirm what patients, chaplains, and medical clinicians have testified to for years: dwelling on the truth of God's Word can enhance health. Dr. Backus brings biblical balance to mind/body issues while staying clear of New Age philosophies. (Originally titled The Healing Power of a Healthy Mind.)
