God always knows what people are thinking, and when those people that are not Jews believed in Jesus, God gave them the Holy Spirit to show them that he wants them in his family too. You see, at first he gave the Holy Spirit to us, then he gave the Holy Spirit to those people that are not Jews.
Then Paul put his hands on their heads, and the Holy Spirit came into each one of them. The Holy Spirit gave them the power to talk in different languages. And the Holy Spirit gave them messages, and they told everyone those messages.
After they finished praying God shook the house that they were meeting in, and the Holy Spirit went into them all and filled them. They kept on telling everyone God’s message about Jesus, and they weren’t frightened of anyone.
