Paul helped some men to become real believers in Jesus.

Acts 19:1-7

19 While Apollos was at Corinth, Paul left the places in Phrygia and Galatia provinces where he had been visiting, and traveled through Asia province back to Ephesus. He met some people who said that they were believers. 2 He asked them, “Did you receive the Holy Spirit when you believed God’s message?” They answered, “No, we (exc) did not. We have not even heard that there is a Holy Spirit.” 3 So Paul asked, “So when you were baptized, what were you showing?” They replied, “We were showing that we (exc) believed what John the Baptizer taught.” 4 Paul said, “John baptized people who turned away from their sinful behavior. He also told the people to believe in the one who would come after he had come, and that was Jesus.” 5 So, when those men heard that, they were baptized to affirm that they believed [MTY] in the Lord Jesus. 6 After that, Paul placed his hands on their heads one by one, and the power of the Holy Spirit came upon each of them. The Holy Spirit enabled them to speak in various languages [MTY] that they had not learned, and they also spoke messages that the Holy Spirit revealed to them. 7 There were about twelve men whom Paul baptized and who received the power of the Holy Spirit.
