At Pentecost the disciples heard the sound of a violent wind. I imagine this to be like the noise of a tornado. "It filled the whole house where they were sitting" (Acts 2:2). Based on our knowledge of the disciples since the death of Jesus, and the noise of a tornado, one would expect the next sentence to be: And they were afraid. But it's not. Instead Luke says, "Divided tongues, as of fire, appeared among them, and a tongue rested on each of them. All of them were filled with the Holy Spirit and began to speak in other languages, as the Spirit gave them ability" (Acts 2:3-4).
They got hit by the freight train, the tornado of God.
