The Gospel of Mark can be read in about an hour and a half.  The show's host, Martin Tanner, suggests that during the Christmas season everyone should read the Gospel of Mark. It is the earliest Gospel, and in effect, the Gospel of Peter, because John Mark, the author was writing Peter's description of what Jesus said and did.  The Gospel of Mark is a marvelous testimony of Jesus as the Messiah promised by God, to save his chosen people.  This is what people are celebrating at Christmastime.
