In today's first reading from Acts 4, we read that the Apostles "were all filled with the Holy Spirit and continued to speak the word of God with boldness." Our Gospel reading is from John 3, where Jesus and Nicodemus are having a conversation about being "born again."
Pentecost was a life-changing experience for the Church, and especially for the Apostles. Today we see that "the place where they were gathered shook." They were filled with the Holy Spirit, who empowered them with holy boldness.
Too many people think that holy boldness is all about the things we say. But that can be way off base. What about standing up for the defenseless in this culture of death? Or being a friend to someone who is marginalized? Holy boldness is really just following the lead of the Holy Spirit, doing or saying what the Spirit moves you to do or say, even when it is difficult or unpopular.
Father, you have filled us with Your Spirit. Help us to boldly proclaim the Gospel today, whether we need to open our mouths or not. Amen.
