This meditation reflects on Psalm 149 and the call to "sing to the Lord a new song." Drawing on St. Augustine, we explore how this song is not just sung with our voices, but lived out as the joyful "new life" we receive in baptism. We'll consider how our daily work, forgiveness, and even our sanctified suffering can become an "existential song" that gives glory to God, asking for the grace to ensure our lives are in harmony with the faith we profess.
