26 Then they arrived at the country of the Ger'asenes, which is opposite Galilee. 27 And as he stepped out on land, there met him a man from the city who had demons; for a long time he had worn no clothes, and he lived not in a house but among the tombs. 28 When he saw Jesus, he cried out and fell down before him, and said with a loud voice, "What have you to do with me, Jesus, Son of the Most High God? I beseech you, do not torment me." 29 For he had commanded the unclean spirit to come out of the man. (For many a time it had seized him; he was kept under guard, and bound with chains and fetters, but he broke the bonds and was driven by the demon into the desert.) 30 Jesus then asked him, "What is your name?" And he said, "Legion"; for many demons had entered him. 31 And they begged him not to command them to depart into the abyss. 32 Now a large herd of swine was feeding there on the hillside; and they begged him to let them enter these. So he gave them leave. 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 were drowned. 34 When the herdsmen saw what had happened, they fled, and told it in the city and in the country. 35 Then people went out to see what had happened, and they came to Jesus, and 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 And those who had seen it told them how he who had been possessed with demons was healed. 37 Then all the people of the surrounding country of the Ger'asenes asked him to depart from 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 he sent him away, saying, 39 "Return to your home, and declare how much God has done for you." And he went away, proclaiming throughout the whole 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.
