An old brain-teaser: "A man and his son are on a fishing trip when their boat capsizes. The son is injured. His father rushes him to the nearest hospital, where they are immediately admitted into the emergency room. Suddenly a doctor sprints into the room and runs to the child, crying 'My son! My son!' " How is this possible?
Jesus asks the Pharisees a similar question: Can the Messiah be the son of David -- the son of Man -- as well as God? The answer to our first brain-teaser is easy. The answer to Jesus' brain-teaser is not.
