Pentecost celebrates the presence of God’s Holy Spirit. The central story in the Book of Acts tells of the followers of Jesus gathered in a house after the risen Christ departed from them. A rush of violent wind fills the house and tongues of fire dance on their heads. And they are filled with the Holy Spirit. Each of them begins to speak in another language, so that diverse peoples from many different places hear and understand in their own language. (Acts 2:1-21) It is like a great reversal of an ancient story of people building a city and tower to the heavens. And God sees their human arrogance and causes everyone to begin speaking a different language, and they are scattered across the earth, unable to understand one another. And the city and tower are called, Babel. (Genesis 11:1-9)
