Gray Matter is a fascinating account of Dr. David Levy's decision to begin asking his patients if he could pray for them before surgery. Each chapter focuses on a specific case, opening with a detailed description of the patient's diagnosis and the procedure that will need to be performed, followed by the prayer "request." From there, readers get to look over Dr. Levy's shoulder as he performs the operation, and then we wait--right alongside Dr. Levy, the patients, and their families--to see the final results. --from publisher description.
