4 Therefore those who were scattered went everywhere preaching the word. 5 Then Philip went down to the city of Samaria and preached Christ to them. 6 And the multitudes with one accord heeded the things spoken by Philip, hearing and seeing the miracles which he did. 7 For unclean spirits, crying with a loud voice, came out of many who were possessed; and many who were paralyzed and lame were healed. 8 And there was great joy in that city. 9 But there was a certain man called Simon, who previously practiced sorcery in the city and astonished the people of Samaria, claiming that he was someone great, 10 to whom they all gave heed, from the least to the greatest, saying, "This man is the great power of God." 11 And they heeded him because he had astonished them with his sorceries for a long time. 12 But when they believed Philip as he preached the things concerning the kingdom of God and the name of Jesus Christ, both men and women were baptized. 13 Then Simon himself also believed; and when he was baptized he continued with Philip, and was amazed, seeing the miracles and signs which were done.

Commentary on Acts 8:1-4
(Read Acts 8:1-4)
Though persecution must not drive us from our work, yet it may send us to work elsewhere. Wherever the established believer is driven, he carries the knowledge of the gospel, and makes known the preciousness of Christ in every place. Where a simple desire of doing good influences the heart, it will be found impossible to shut a man out from all opportunities of usefulness.
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.
