In Genesis 11 we see the way God disrupts humanity's plans for power at Babel. There is division and frustration. In Revelation 21 we get a glimpse of a future where people, cultures and cities are redeemed and once again united under Christ. And at Pentecost, in Acts 2, we see how the coming of the Holy Spirit undoes the curse of Babel and shapes God's people for unity and true worship, pointing to the future outlined in Revelation.
