Father Justin explores doubt and faith, reminding that questioning our beliefs is not a sign of weakness, but an opportunity for growth. The sermon centers on the story of Thomas from St. John's Gospel, highlighting how even Jesus' first-century followers struggled with belief. Thomas's story challenges us to reconsider our understanding of faith. Faith is not about being 100% certain of a set of propositions, but about engaging in an honest conversation with God. We're encouraged to bring our doubts, fears, and questions directly to God, just as Thomas did.
