In my church we've been exploring the idea that God is fully present in each person of the Trinity. Recently our focus has been on the Holy Spirit. On Trinity Sunday, a week after Pentecost, it might be fruitful to consider the implications of this full presence of God in the Spirit.
It's commonly suggested that the Pentecost story is a reversal of the chaotic separation of the Tower of Babel. That point gets debated. What isn't debatable is that people remain separated in abundant ways.
I grew up long before the age of YouTube. My Sunday school rooms were in a church basement in western Nebraska. We didn't even have filmstrips! When I think back to the story of the first Pentecost, I remember an illustration on one of those Sunday school leaflets that we kids took home each week. The Pentecost leaflet showed men in robes standing in a room looking out of some windows.
