26 And they came to the country of the Gerasenes, which is opposite Galilee. 27 And when he had come to the land, there came to him a certain man from the town who had evil spirits; and for a long time he had had no clothing on, and was not living in a house but in the place of the dead. 28 And when he saw Jesus, he gave a loud cry and went down on the earth before him and in a loud voice said, What have I to do with you, Jesus, Son of the Most High God? Do not be cruel to me. 29 For he gave an order to the evil spirit to come out of the man. For frequently it would take a grip of him: and he was kept under control, and prisoned with chains; but parting the chains in two, he would be sent by the driving of the evil spirit into waste places. 30 And Jesus said to him, What is your name? And he said, Legion; for a number of spirits had gone into him. 31 And they made a request to him that he would not give them an order to go away into the deep.

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.
