Paul's letter to the Ephesians reveals God's blueprint for church unity in a divided world. Walking worthy of our calling requires humility, gentleness, and patience - characteristics that can only be developed through the Holy Spirit's transforming power. Unity already exists among believers through Christ's finished work, but we must make every effort to maintain it. Paul provides seven theological foundations for this unity: one body, one Spirit, one hope, one Lord, one faith, one baptism, and one God and Father. Our unity serves as a powerful witness to the world of the gospel's transforming power.
