27 and he having gone forth upon the land, there met him a certain man, out of the city, who had demons for a long time, and with a garment was not clothed, and in a house was not abiding, but in the tombs, 28 and having seen Jesus, and having cried out, he fell before him, and with a loud voice, said, 'What—to me and to thee, Jesus, Son of God Most High? I beseech thee, mayest thou not afflict me!' 29 For he commanded the unclean spirit to come forth from the man, for many times it had caught him, and he was being bound with chains and fetters—guarded, and breaking asunder the bonds he was driven by the demons to the deserts. 30 And Jesus questioned him, saying, 'What is thy name?' and he said, 'Legion,' (because many demons were entered into him,) 31 and he was calling on him, that he may not command them to go away to the abyss, 32 and there was there a herd of many swine feeding in the mountain, and they were calling on him, that he might suffer them to enter into these, and he suffered them, 33 and the demons having gone forth from the man, did enter into the swine, and the herd rushed down the steep to the lake, and were choked.

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.
