The Epistle to the Ephesians

Introduction to the Book of Ephesians

The Book of Ephesians is one of the most profound writings of the apostle Paul concerning the believer’s identity, position, and calling in Christ. Written to strengthen the Church in the knowledge of what God has accomplished through Jesus Christ, Ephesians reveals the eternal purpose of God: to gather all things together in Christ and to form a people who display His wisdom, holiness, power, and glory.

Paul identifies himself as “an apostle of Jesus Christ by the will of God” and addresses the saints and faithful in Christ Jesus (Ephesians 1:1). Traditionally, Ephesians is associated with the believers at Ephesus, an influential city of Asia Minor known for commerce, pagan religion, and the famous temple of Artemis, called Diana in the KJV. Against this spiritual and cultural background, Paul presents Christ as exalted “far above all principality, and power, and might, and dominion” (Ephesians 1:21).

A central expression throughout Ephesians is “in Christ.” Paul teaches that salvation is more than deliverance from sin; it brings the believer into a new spiritual position and covenant relationship with God through Christ. In Him, believers are chosen, accepted, redeemed, forgiven, sealed with the Holy Spirit, made alive, raised together, and seated together in heavenly places. These blessings are not earned through human merit but are given according to the grace, purpose, and will of God.

Ephesians also reveals the mystery of Christ—that through the gospel, believing Jews and Gentiles are brought together into one body. Christ has broken down the dividing wall and created in Himself “one new man” (Ephesians 2:15). Therefore, the Church is not merely a gathering of individuals who share the same faith; it is a spiritual body of which Christ is the Head and believers are members joined together in Him.

Paul further describes the Church as God’s workmanship, God’s household, a holy temple, the Body of Christ, and the Bride of Christ. Through these images, Ephesians reveals both the privilege and responsibility of those who belong to Christ. The Church is called to manifest the wisdom of God, preserve the unity of the Spirit, grow into spiritual maturity, and demonstrate the character of Christ before the world.

The book naturally moves from revelation to responsibility. Chapters 1–3 emphasize what God has accomplished for believers in Christ: spiritual blessings, redemption, reconciliation, adoption, inheritance, access to the Father, and the indwelling presence of the Holy Spirit. Chapters 4–6 then explain how believers should live because of these truths. Paul repeatedly urges the saints to “walk worthy” of their calling.

This worthy walk affects every area of Christian life. Believers are instructed to walk in unity, holiness, love, light, and wisdom. The old manner of life must be put away, while the new man, created after God in righteousness and true holiness, must be manifested. Relationships within the home are also brought under the lordship of Christ as Paul addresses husbands and wives, children and parents, and servants and masters.

Ephesians concludes by revealing that the Christian life includes spiritual warfare. Paul commands believers to “be strong in the Lord, and in the power of his might” (Ephesians 6:10). The struggle is ultimately not against flesh and blood but against spiritual powers of wickedness. Therefore, believers must put on the whole armour of God, stand in truth and righteousness, walk in the preparation of the gospel of peace, take up faith and salvation, wield the Word of God, and continue in prayer.

The message of Ephesians can therefore be understood through three great movements: our position in Christ, our walk in Christ, and our stand in Christ. Before Paul tells believers how to walk or how to stand, he first establishes who they are and where God has positioned them through Christ.

Ephesians calls the Church to understand the greatness of its salvation and the riches of its inheritance. Paul prays that the “eyes of your understanding” would be enlightened so that believers might know the hope of God’s calling, the riches of His inheritance in the saints, and the exceeding greatness of His power toward those who believe (Ephesians 1:18–19).

Ultimately, the Book of Ephesians is a revelation of God’s eternal purpose in Christ and the Church’s place within that purpose. It teaches believers not only what Christ has done for them, but who they have become because they are in Him. As the believer grows in this knowledge, doctrine becomes life: identity produces conduct, grace produces holiness, revelation produces maturity, and spiritual position produces a life worthy of the calling received from God.
