Acts 19:12
So that from his body were brought unto the sick handkerchiefs or aprons, and the diseases departed from them, and the evil spirits went out of them. So that from his body were brought unto the sick handkerchiefs or aprons, and the diseases departed from them, and the evil spirits went out of them.
Acts 19:12 belongs to Paul's work in Ephesus, the capital of the Roman province of Asia and a great commercial center drawing people from many countries, which was regarded as a promising field for missionary work. There the gospel took root in a stronghold of heathenism and a large church was raised up, and the progress of that work showed God's power working with Paul's efforts and displayed the wonders of God's grace.
During that work God worked special, extraordinary miracles by Paul's hands, mightily displaying divine power by the Spirit with special tokens of divine favor accompanying his labors. Cloths, handkerchiefs or aprons and garments carried from his body to the sick caused diseases to leave them, so that many were healed of physical maladies, and evil spirits to go out of them and depart. These miracles were not worked at the apostles' will, but were granted as the progress of God's work or the honor of His name required. As the suffering woman was healed by touching Christ's garment in faith, the garments became means of healing believers, but the miracles encouraged no blind superstition: the Lord worked them through Paul, and Jesus' name, not Paul's, was magnified.
The miracles were wrought in the name of Jesus of Nazareth, not by using His name as a charm. Done in that name, they displayed divine power far more potent than anything ever before witnessed in Ephesus and beyond anything magicians, sorcerers, jugglers' skill or enchantment could imitate, showing God's power against the lying wonders practiced there. They let the people see that the God of heaven is more powerful than the powers associated with Diana and worshiped by the magicians, and they exalted Paul before the people, even before idolaters themselves, immeasurably above the most powerful and favored of the magicians.
God gave these special miracles to reach magicians and those under their influence in the city of the temple of Diana, proving there was a power above all the powers of the magicians, and that proof brought conversion. Men who tried to imitate the miracles by using the name of Jesus in sorcery were overpowered by the evil spirit and beaten and bruised, because sorcery and Christ cannot mix. The true working of God's power had effect on the people, so the converted destroyed their magic books by burning them to cut off every future temptation to go back to sorcery.
