Acts 19:3-7

Speaking in tongues is a sign of the Baptism of the Holy Spirit. This Baptism enables us to hear and understand Scripture and to speak boldly in the name of Christ. He is the ultimate teacher and His guidance helps us to navigate the trials and tribulations here on earth. Holy Spirit takes the teachings of Jesus and imprints them on our minds and heart. 

Christ within is the hope of glory!

By laying on his hands here, Paul was demonstrating his apostolic authority. He was also affirming the unity of the new church in Ephesus with the church in Jerusalem, whose members were also were empowered by the Holy Spirit to speak in foreign languages. This speaking in tongues was a sign to others that they were part of the body of Christ. NKJ Bible.

Acts 19:3–7 (NKJV)

³ And he said to them, “Into what then were you baptized?”

So they said, “Into John’s baptism.”

⁴ Then Paul said, “John indeed baptized with a baptism of repentance, saying to the people that they should believe on Him who would come after him, that is, on Christ Jesus.”

⁵ When they heard this, they were baptized in the name of the Lord Jesus. ⁶ And when Paul had laid hands on them, the Holy Spirit came upon them, and they spoke with tongues and prophesied. ⁷ Now the men were about twelve in all.

Matthew 3:11 (NKJV)

¹¹ I indeed baptize you with water unto repentance, but He who is coming after me is mightier than I, whose sandals I am not worthy to carry. He will baptize you with the Holy Spirit and fire.

 Mark 1:8 (NKJV)

⁸ I indeed baptized you with water, but He will baptize you with the Holy Spirit.”
