Luke, the 3rd book in the New Testament written by Luke to a man named Theophilus. Luke was a physician and wrote this letter to teach this man about the widely misunderstood Christian religion. Without the book of Luke we would not have the Christmas time story of Jesus in a manger, and the parables of the good Samaritan, the widow who donated her last mite and the prodigal son. Luke focuses on Jesus as the Savior.
