Ephesians was written while Paul was in prison and addressed to believers in and around the city of Ephesus. The letter begins by describing the spiritual blessings believers receive through Christ, including redemption, reconciliation, and adoption into God’s family. Paul then explains how these truths shape the unity of the church, bringing together people from different backgrounds into one body. The second half of the letter applies these themes to everyday relationships and conduct. Believers are encouraged to live in ways that reflect the new life given to them through Christ. Within the New Testament, Ephesians provides one of the clearest explanations of the church’s identity and mission.
