Learn about the incredible faith of the hero on Hacksaw Ridge. The Faith of Desmond Doss not only tells Desmond's incredible story but more importantly, it tells the reader about his faith. Desmond refused to carry a gun, but that doesn't mean he went into battle unarmed. He faced combat with two things more valuable than any man-made weapon--his Bible and prayer. The message of this small book is that through Bible study and prayer, anyone can develop a relationship with God, and achieve greater faith.
