27 And when He stepped out on the land, there met Him a certain man from the city who had demons for a long time. And he wore no clothes, nor did he live in a house but in the tombs. 28 When he saw Jesus, he cried out, fell down before Him, and with a loud voice said, "What have I to do with You, Jesus, Son of the Most High God? I beg You, do not torment me!" 29 For He had commanded the unclean spirit to come out of the man. For it had often seized him, and he was kept under guard, bound with chains and shackles; and he broke the bonds and was driven by the demon into the wilderness. 30 Jesus asked him, saying, "What is your name?" And he said, "Legion," because many demons had entered him. 31 And they begged Him that He would not command them to go out into the abyss. 32 Now a herd of many swine was feeding there on the mountain. So they begged Him that He would permit them to enter them. And He permitted them. 33 Then the demons went out of the man and entered the swine, and the herd ran violently down the steep place into the lake and drowned.

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.
