Peter is a changed man. The Holy Spirit has come upon him to give him comfort in the place of his fear, to give him encouragement in place of his questions, to give him a challenge in place of his silence. Peter has the fire...or perhaps it is better said, the fire has him.
Celebrate the gift of fire that came upon the Apostles on the Day of Pentecost. Celebrate the Holy Spirit with your sisters and brothers in Christ next Sunday, and then be prepared to receive the gift of the Spirit yourself. Come share the grace!
