Peter has been transformed from bungling loudmouth to Biblical scholar and inspired preacher. This was done in the moment in the coming of the Holy Spirit… but also through the careful teaching of Jesus before his ascension (Luke 24:45). Thanks to witnesses like Peter, we also sit at the foot of Jesus. And, in the words of Peter’s sermon, the gift of the Holy Spirit is for “you and for your children.” From fisherman to fisher of men. From loser to leader. May we be so transformed by Word and Spirit into Witnesses.
