Gray Matter is the story of a Christian neurosurgeon named David Levy who learned firsthand what can happen when we are open about our faith, particularly through praying with patients.  I appreciate how Dr. Levy strives to be authentic rather than aloof and empathetic rather than merely sympathetic.  There is a lot to learn from his example of engaging with patients as real people, whose wounds are more than just physical.  This is a powerful book. I recommend it to any pre-med students. – from Joseph Elkins
