5 And Philip, going down to a city of Samaria, preached the Christ to them; 6 and the crowds with one accord gave heed to the things spoken by Philip, when they heard [him] and saw the signs which he wrought. 7 For from many who had unclean spirits they went out, crying with a loud voice; and many that were paralysed and lame were healed. 8 And there was great joy in that city. 9 But a certain man, by name Simon, had been before in the city, using magic arts, and astonishing the nation of Samaria, saying that himself was some great one. 10 To whom they had all given heed, from small to great, saying, This is the power of God which is called great. 11 And they gave heed to him, because that for a long time he had astonished them by his magic arts. 12 But when they believed Philip announcing the glad tidings concerning the kingdom of God and the name of Jesus Christ, they were baptised, both men and women. 13 And Simon also himself believed; and, having been baptised, continued constantly with Philip; and, beholding the signs and great works of power which took place, was astonished.

Commentary on Acts 8:5-13
(Read Acts 8:5-13)
As far as the gospel prevails, evil spirits are dislodged, particularly unclean spirits. All inclinations to the lusts of the flesh which war against the soul are such. Distempers are here named, the most difficult to be cured by the course of nature, and most expressive of the disease of sin. Pride, ambition, and desire after grandeur have always caused abundance of mischief, both to the world and to the church. The people said of Simon, This man is the great power of God. See how ignorant and thoughtless people mistake. But how strong is the power of Divine grace, by which they were brought to Christ, who is Truth itself! The people not only gave heed to what Philip said, but were fully convinced that it was of God, and not of men, and gave up themselves to be directed thereby. Even bad men, and those whose hearts still go after covetousness, may come before God as his people come, and for a time continue with them. And many wonder at the proofs of Divine truths, who never experience their power. The gospel preached may have a common operation upon a soul, where it never produced inward holiness. All are not savingly converted who profess to believe the gospel.
