In his sermon “A Mentality,” Pastor Adam Barton urges a mindset shift for Christians towards their role in the church. Using the analogy of animal groups, he challenges the congregation to redefine how they view a group of Christians. Drawing from Matthew 16:13-18, Pastor Adam highlights the importance of recognizing Jesus as the foundation of the church and emphasizes the need for Christians to unite in a fearless mission to bring light to the world.
