Paul urges Christians to maintain unity through living in a manner worthy of their calling. He discusses the grounds of unity - that believers share one body, spirit, hope, Lord, faith, baptism and God. Paul also addresses the gifts given to the church to strengthen unity, such as apostles, prophets, evangelists, and pastor-teachers. Finally, he explains how unity grows as believers pursue maturity through Christ-likeness, stability, speaking truth in love, and cooperation.
