LEADERSHIP STRUCTURE
_______
We believe that Jesus is the true leader and ultimate pastor of our church. We believe that Jesus provides his church with leaders who give their lives to serve and care for the church. Jesus gave the church a few offices to help structure leadership. First, we are led by what we call elders or pastors. Second, we also have deacons who function in a lead servant role. Third, our members function like an office. We believe that membership at the church is an important commitment that comes with responsibilities to live out the "one anothers" of the faith to care for each other and to be involved in the direction and decision making of the church.
