Burning Of Books
Those who practiced sorcery burnt their books. Because they wanted to get their lives right with God.
They had no need for things from their old life. Because to hold on to them would trip them up in their new life style.
Background Reading:
Acts 19:11-20
Paul in Ephesus
19:11 God did extraordinary miracles through Paul, 12so that even handkerchiefs and aprons that had touched him were taken to the sick, and their illnesses were cured and the evil spirits left them.
13 Some Jews who went around driving out evil spirits tried to invoke the name of the Lord Jesus over those who were demon-possessed. They would say, "In the name of Jesus, whom Paul preaches, I command you to come out." 14 Seven sons of Sceva, a Jewish chief priest, were doing this. 15 One day the evil spirit answered them, "Jesus I know, and I know about Paul, but who are you?" 16 Then the man who had the evil spirit jumped on them and overpowered them all. He gave them such a beating that they ran out of the house naked and bleeding.
17 When this became known to the Jews and Greeks living in Ephesus, they were all seized with fear, and the name of the Lord Jesus was held in high honor. 18 Many of those who believed now came and openly confessed their evil deeds. 19 A number who had practiced sorcery brought their scrolls together and burned them publicly. When they calculated the value of the scrolls, the total came to fifty thousand drachmas. 20 In this way the word of the Lord spread widely and grew in power.
