What does the Holy Spirit do? The early Christians first experience of the Holy Spirit was powerful. In the book of Acts, there is an explosion of the Spirit's activity - violent winds shake rooms; tongues of fire appear; the disciples stumble out into the street like drunk people; Paul is blinded and knocked from his horse; the Holy Spirit falls in power on everyone - even the Gentiles. All who experienced Him were empowered to preach the gospel of Jesus, to heal the sick and to raise the dead, to prophecy and speak in tongues. This is the work of the Spirit and He is available to all of us, all the time. Christianity is not simply about belief or behavior. It is a dynamic ongoing experience of Jesus’ power and presence through the person of his Holy Spirit.
