In this opening message of the Unstoppable series, Pastor Tim Dunn launches a journey through the book of Acts by focusing on the promise of power given to the early church. Acts reminds us who the church truly is—not defined by culture, influence, or branding, but formed by the risen Christ and empowered by the Holy Spirit. This sermon explores Acts 1:1–11, where Jesus calls His followers to wait for the Holy Spirit before stepping into their mission as witnesses to the ends of the earth. Pastor Tim unpacks the role of the Spirit in empowering courage, unity, and faithful witness in a complex and often resistant world. Acts shows us that God’s work continues not through human effort alone, but through divine empowerment.
