John 14:15-18; Acts 2:1-39
Before Jesus went back to Heaven, He promised His disciples that he would send them the gift of God's Holy Spirit. Ten days after Jesus returned to Heaven, there was a Jewish holy day. Jewish people living in many other nations came to Jerusalem to celebrate this. The disciples of Jesus were also there, all together in one place. Suddenly, God's Holy Spirit came and filled all the disciples, as Jesus had promised. These Jewish people from all those other nations were surprised when the disciples began speaking in all of their languages, about the wonderful things that God had done. God's Spirit is powerful. Now the Holy Spirit lives in all true Christians and gives them power to love and obey Jesus.
