Acts 19: The Gift of the Holy Ghost
While Apollos was in Corinth, Paul passed through the upper coasts of Epheus where he found certain Disciples of Christ who had not yet received the Holy Ghost;
“He said unto them, Have ye received the Holy Ghost since ye believed? And they said unto him, We have not so much as head whether there be any Holy Ghost. And he said unto the, Unto what then where ye baptized? And they said, Unto John’s baptism. Then said Paul, John verily baptized with the baptism of repentance, saying unto the people, that they should believe on him which should come after him, that is, on Christ Jesus. When they heard this, they were baptized in the name of the Lord Jesus. And when Paul had laid his hands upon them, the Holy Ghost came upon them; and they spake with tongues, and prophesied.” (Acts 19:2-6)
When Paul had asked them if they had received the Holy Ghost, they knew nothing of it. These people thought they had received a valid baptism with the proper authority. However, Paul, an Apostle of the Lord told them that they had been baptized without the actual Authority. So when the people heard and understood this, they were RE-BAPTIZED, because a baptism without the proper Authority is just getting wet, and serves no purpose. Paul then gave them the power and gift of the Holy Ghost, by the laying on of hands, by the proper Authority. Thus, it is important to have proper Authority to get a proper baptism. This Authority was lost some time after Paul was an Apostle, but has been restored in these Latter-days.
While in Ephesus Paul has a mixed response, but performs miraculous healings. The seven sons of Sceva, Jewish exorcists, try to exorcise by the name of the Lord Jesus. However, the evil spirits do not recognize them or their proper Authority and are beaten by the evil spirits. Many in Ephesus renounce occult objects. Demetrius, a maker of idols, opposes Paul because his business has suffered. A riot starts, which is finally calmed by a city clerk.
