This piece includes a sermon based on two texts of the Revised Common Lectionary for the First Sunday of Pentecost (Year C), Genesis 11:1-9 (the Tower of Babel) and Acts 2:1-13 (the Holy Spirit visits the apostles). Included after the sermon is an exegetical rationale which explores various Pentateuchal backgrounds and themes while reflecting on the audience and setting for the sermon. Themes include divine punishment and mercy, human folly, God's promise, mission, and the Holy Spirit. Applications for this material are open-ended and could include preaching, adult bible study, and reading for reflection and discussion among church councils, mission developers, or even stewardship committees.
