26 And they arrived in the country of the Gadarenes, which is over against Galilee. 27 And as he got out [of the ship] on the land, a certain man out of the city met him, who had demons a long time, and put on no clothes, and did not abide in a house, but in the tombs. 28 But seeing Jesus, he cried out, and fell down before him, and with a loud voice said, What have I to do with thee, Jesus Son of the Most High God? I beseech thee torment me not. 29 For he had commanded the unclean spirit to go out from the man. For very often it had seized him; and he had been bound, kept with chains and fetters; and breaking the bonds he was driven by the demon into the deserts. 30 And Jesus asked him saying, What is thy name? And he said, Legion: for many demons had entered into him. 31 And they besought him that he would not command them to go away into the bottomless pit.

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.
