Pentecost Sunday celebrates the coming of the Holy Spirit in a new way following the resurrection and ascension of Jesus. Rob Muthiah reviews how the Spirit of God is present in creation, throughout the Old Testament and in the life and ministry of Jesus. And so, Rob asks, what about today?He goes on to use a metaphor developed by theologian and vicar Sam Wells, of performing a play that is missing an act — which we are assigned to improvise. Improv involves following the preceding acts and knowing the act to come. This is how the church discerns God’s movement today: following scripture, knowing what’s to come, filled with and gifted by the Spirit, and guided by the Holy Spirit's presence.
