In this week’s sermon, we look back to Peter’s first message at Pentecost and the powerful response it sparked in the hearts of his listeners (Acts 2:22–47). Preaching on the ascension of Christ, Peter’s words ignited a movement—one that gave birth to the first churches of the New Testament era. This message explores how those early believers responded: by devoting themselves to the Word, to prayer, to the sacraments, and to one another in loving fellowship. Their devotion became the foundation of the Church—and a model for us today.
