Paul explains in verse 4 that John’s baptism was a baptism of repentance. John told the people to believe in the One who was coming after him – that is, in Jesus. When they heard this, they were baptised in the name of the Lord Jesus. Then Paul laid his hands on them, and the Holy Spirit came upon them. They spoke in tongues and prophesied – and there were about twelve men. What an incredible picture of the power of the Holy Spirit!
