The miracle stories found in the Gospel of Mark are considered to be very important element in understanding the Mark Theology. Above all, Mark made the gentile mission to be his main concern of the gospel through the miracle stories. Mark always had a habit of adding a regional influence to introducing his miracle stories. The Miracle stories include places such as Galilee, Syro-Phoenicia, Decapolis, Gerasene. These geographical locations involved in the miracle stories are all located in gentile areas. Galilee played an important part in the gospel mission. Jesus made his missionary journeys into gentile territories,not including Judea. According to the miracles, all the miracles occurred in gentile territories and in many cases the people related to the miracles were considered gentile. It is notable in the miracle stories that Jesus fed four thousand gentile people. In the composition of those miracle stories, Mark used many special words and expressions strongly visualizing gentile elements,such as ‘four and seven,’ ‘baskets,’ ‘give thanks,’ ‘from afar,’ ‘'dogs’etc. It had become obvious that those words and expressions are closely related with gentile people and the gentile world. In such meanings, they are playing a great role for the gentile gospel mission. The importance placed by Mark upon the gentile mission of the gospel in his composing the miracle stories appears even more remarkable in the gentile mission of gospel. We can see this when Jesus ordered, “Go home to your friends and tell him how much the Lord has done for you”(5:19). This is found in the Exorcism Narrative of Gerasene. Mark on the contrary to the secrecy command at normal times, is obviously quoting Jesus as he is stating the gentile mission of the Gospel at in this miracle story. Even in the still of the storm we can find that Jesus traveled to the gentile world for the mission of gospel. In the story the “other side” through the theme of “crossing.”Seen from such viewpoints, Mark can been seen to have opened the door for the gentile mission of the gospel throughout all the miracle stories.
