When Peter and John arrived, they prayed for the Samaritan believers to receive the Holy Spirit.
Peter said to them, “Change your hearts and lives and be baptized, each one of you, in the name of Jesus Christ. Then God will forgive your sins, and you will receive the gift of the Holy Spirit.
because I know that your prayers and the help the Spirit of Jesus Christ gives me will cause this trouble to result in my freedom.
To say it another way, if two of you on earth agree on anything you pray for, my Father in heaven will do what you ask.
He asked them, “Did you receive the Holy Spirit when you believed?” These followers said to him, “We have never even heard of a Holy Spirit!”
So those who have the gift of speaking in a different language should pray that they can also interpret what they say.
