26 Then they arrived at the country of the Gerasenes, which is opposite Galilee. 27 As he stepped out on land, a man of the city who had demons met him. For a long time he had worn no clothes, and he did not live in a house but in the tombs. 28 When he saw Jesus, he fell down before him and shouted at the top of his voice, "What have you to do with me, Jesus, Son of the Most High God? I beg you, do not torment me"- 29 for Jesus had commanded the unclean spirit to come out of the man. (For many times it had seized him; he was kept under guard and bound with chains and shackles, but he would break the bonds and be driven by the demon into the wilds.) 30 Jesus then asked him, "What is your name?" He said, "Legion"; for many demons had entered him. 31 They begged him not to order them to go back into the abyss. 32 Now there on the hillside a large herd of swine was feeding; and the demons begged Jesus to let them enter these. So he gave them permission. 33 Then the demons came out of the man and entered the swine, and the herd rushed down the steep bank into the lake and was drowned. 34 When the swineherds saw what had happened, they ran off and told it in the city and in the country. 35 Then people came out to see what had happened, and when they came to Jesus, they found the man from whom the demons had gone sitting at the feet of Jesus, clothed and in his right mind. And they were afraid. 36 Those who had seen it told them how the one who had been possessed by demons had been healed. 37 Then all the people of the surrounding country of the Gerasenes asked Jesus to leave them; for they were seized with great fear. So he got into the boat and returned. 38 The man from whom the demons had gone begged that he might be with him; but Jesus sent him away, saying, 39 "Return to your home, and declare how much God has done for you." So he went away, proclaiming throughout the city how much Jesus had done for him.

Commentary on Luke 8:22-40
(Read Luke 8:22-40)
Those that put to sea in a calm, even at Christ's word, must yet prepare for a storm, and for great peril in that storm. There is no relief for souls under a sense of guilt, and fear of wrath, but to go to Christ, and call him Master, and say, I am undone, if thou dost not help me. When our dangers are over, it becomes us to take to ourselves the shame of our own fears, and to give Christ the glory of our deliverance. We may learn much out of this history concerning the world of infernal, malignant spirits, which though not working now exactly in the same way as then, yet all must at all times carefully guard against. And these malignant spirits are very numerous. They have enmity to man and all his comforts. Those under Christ's government are sweetly led with the bands of love; those under the devil's government are furiously driven. Oh what a comfort it is to the believer, that all the powers of darkness are under the control of the Lord Jesus! It is a miracle of mercy, if those whom Satan possesses, are not brought to destruction and eternal ruin. Christ will not stay with those who slight him; perhaps he may no more return to them, while others are waiting for him, and glad to receive him.
