In Ephesians chapters 1-3, Paul begins by unfolding the manifold spiritual blessings and riches believers have in Christ, including election, redemption, and adoption as sons. He emphasizes the magnificence of God’s grace, affirming that believers are saved by grace through faith, a gift from God, not by works. Paul reveals the mystery of the Gospel: Jews and Gentiles are united in one body through Christ, breaking down the dividing wall of hostility and granting both groups access to the Father by one Spirit. He prays for the Ephesian believers to have their hearts enlightened to know the hope of their calling, the riches of God’s glorious inheritance, and the immeasurable greatness of His power. The first three chapters thereby serve as a profound theological foundation, expounding on themes of unity, grace, spiritual wealth, and the reconciling power of the Gospel.
