Mark 5:8
For he said unto him, Come out of the man, thou unclean spirit.
For he said unto him,.... Or he had said unto him, as soon as he came up to him, and fell before him; even before he had confessed, and adjured him; and which indeed drew out the confession from him, that he was superior to him, and therefore became his supplicant:
Come out of the man, thou unclean spirit; which was said with so much authority and power, that there was no withstanding it: the devil knew he was not a match for him; that he must, at his command, quit his possession, and therefore fell to confession and entreaty. Christ will not dwell where Satan does; when therefore he is about to take up his residence in the hearts of any, he outs with Satan; he binds the strong man armed, and dispossesses him; he causes the spirit of uncleanness to depart; he sanctifies the heart by his grace and Spirit, and so makes it a proper habitation for him to dwell in by faith; and this is done by mighty power: a man cannot deliver himself out of the hands of Satan, or cause him to quit his hold of him, or the unclean spirit to depart; nor can he sanctify and cleanse himself, and make himself meet for the master's use: this is all owing to efficacious grace.
