The book of Ephesians focuses on the Church as an entity and its function in this world. Paul emphasizes that through Christ, believers are united as one body, called to live in faith, love, unity, and holiness. The Church is not simply a gathering of individuals, but the Body of Christ—created to reflect God’s grace, demonstrate His wisdom, and carry out His purposes in the world. Ephesians reminds believers of who they are in Christ and challenges them to live in a way that demonstrates that identity to others.
