Seth Phipps' message, titled "Shadows and the Spirit," centered on the idea of one's reputation, or "rep." He emphasized that who we represent determines our influence and reputation. Using the story from Acts 5, where people sought healing from Peter's shadow, he illustrated the power of a strong reputation grounded in faith. Phipps stressed that believers have the same authority and power as the disciples, through the Holy Spirit, to impact the world around them. He encouraged the audience to reflect on their current and desired reputation, and to boldly represent Jesus through faith and obedience. The key takeaway was that Christians are marked by God, belong to Jesus, and are full of the Spirit, empowering them to make a significant difference in the world.
