26 So they arrived in the region of the Gerasenes, across the lake from Galilee. 27 As Jesus was climbing out of the boat, a man who was possessed by demons came out to meet him. For a long time he had been homeless and naked, living in a cemetery outside the town. 28 As soon as he saw Jesus, he shrieked and fell down in front of him. Then he screamed, "Why are you interfering with me, Jesus, Son of the Most High God? Please, I beg you, don't torture me!" 29 For Jesus had already commanded the evil spirit to come out of him. This spirit had often taken control of the man. Even when he was placed under guard and put in chains and shackles, he simply broke them and rushed out into the wilderness, completely under the demon's power. 30 Jesus demanded, "What is your name?" "Legion," he replied, for he was filled with many demons. 31 The demons kept begging Jesus not to send them 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.
