Mark 5:1-20 (NIV)
They went across the lake to the region of the Gerasenes. When Jesus got out of the boat, a man with an evil spirit came from the tombs to meet him. This man lived in the tombs, and no one could bind him any more, not even with a chain. For he had often been chained hand and foot, but he tore the chains apart and broke the irons on his feet. No one was strong enough to subdue him. Night and day among the tombs and in the hills he would cry out and cut himself with stones. When he saw Jesus from a distance, he ran and fell on his knees in front of him. He shouted at the top of his voice, “What do you want with me, Jesus, Son of the Most High God? Swear to God that you won’t torture me!” For Jesus had said to him, “Come out of this man, you evil spirit!” Then Jesus asked him, “What is your name?” “My name is Legion,” he replied, “for we are many.” And he begged Jesus again and again not to send them out of the area. A large herd of pigs was feeding on the nearby hillside. The demons begged Jesus, “Send us among the pigs; allow us to go into them.” He gave them permission, and the evil spirits came out and went into the pigs. The herd, about two thousand in number, rushed down the steep bank into the lake and were drowned. Those tending the pigs ran off and reported this in the town and countryside, and the people went out to see what had happened. When they came to Jesus, they saw the man who had been possessed by the legion of demons, sitting there, dressed and in his right mind; and they were afraid. Those who had seen it told the people what had happened to the demon-possessed man—and told about the pigs as well. Then the people began to plead with Jesus to leave their region. As Jesus was getting into the boat, the man who had been demon-possessed begged to go with him. Jesus did not let him, but said, “Go home to your family and tell them how much the Lord has done for you, and how he has had mercy on you.” So the man went away and began to tell in the Decapolis how much Jesus had done for him. And all the people were amazed.
Wow...Jesus comes to truly set this captive free. He commands the legion of demons to leave this man. Jesus is not intimidated because this thing speaks that they are many; a legion is nothing to the Lord. Whether is one evil spirit or many they all must bow. At the command, the Spoken Word of God they leave and this man is set free and restored to his right mind! Glory to the Most High God; every evil thing must bow its knee to Jesus Christ.
I find it interesting that the people are noted to be afraid after the man is set free. Ok....prior to Christ's arrival this man is tormented, living in a cemetery and this bothers no one? Now Christ shows up and all creation trembles; every soul and every demonic thing. Why? God has sent his son to set people free; free from sin that leads to death.
He has come and in the end every demonic thing will be sent to their destination. (And the devil, who deceived them, was thrown into the lake of burning sulfur, where the beast and the false prophet had been thrown. They will be tormented day and night for ever and ever. Revelation 20:10) So why were the people afraid? Why did they want Jesus to leave? I venture that the fear here is a reality check on their own state.
I'm just thinking; here is Jesus (God in the flesh) he has authority over legions and that which man could not defeat. Sin has a way of wanting to keep its friendship and loyalty with us. Sin will try to keep us shackled; Sin does not want to give us up so quickly. When we face Christ their is a check; a check to see if we are right. His presence alone can cause every demon in hell to tremble and bow.
Remember the demon possessed man saw Jesus from a distance and ran and bowed....Hallelujah! Perhaps the people were afraid that they too would have to give an account for the way they were living. Maybe they were not sleeping in the graveyard, but they were dead apart from God's saving grace. Jesus does leave the region but he leave a witness, the freed man, and he tells him "Go home to your family and tell them how much the Lord has done for you".
We are God's witnesses to speak of the saving power of he Most High God; the One that has come to set men free; to take the dead man and give him life; eternal life! (He said to them, “Go into all the world and preach the good news to all creation. Mark 16:15)
