Acts Bible Study Chapter 19: “Did you receive the Holy Spirit when you believed?” “No”, they replied, “we have never even heard that there is a Holy Spirit.” “Well then, how were you baptised?” asked Paul. “We were baptised with John’s baptism,” they replied.
“John’s baptism was a baptism to show a change of heart,” Paul explained, “but he always told the people that they must believe in the one who should come after him, that is, in Jesus.”
When these men heard this they were baptised in the name of the Lord Jesus, and then, when Paul had laid his hands on them, the Holy Spirit came upon them and they began to speak with tongues and the inspiration of prophets. (There were about twelve of them in all.) (Acts 19.1-7, PHILLIPS)
