The Argument of St. Paul's Epistle to the Ephesians
Ephesus was a well-known city where God raised up a church through Paul’s preaching. Later, while Paul was imprisoned, he wrote this letter to strengthen the believers. He saw that they needed to be firmly grounded in the truth so that they would not be shaken.
God’s Grace in Saving Us (Chapters 1–3)
Paul begins by lifting their eyes to God’s grace. He teaches that their salvation did not begin with them, but with God’s eternal choice. Before they were born, God had already purposed to bring them into His kingdom. This shows that salvation flows entirely from His mercy and love.
Because this truth is so deep, Paul prays that they would truly understand Christ, not just in their minds, but in their hearts.
He then reminds them of their former condition. Before Christ, they were spiritually dead, lost, and without hope. They were outsiders, separated from God and His promises. By setting their past beside their present, Paul helps them see how great God’s mercy really is. We only grasp the beauty of grace when we remember how desperate we once were.
One People in Christ
Paul also explains that he was called especially to bring the gospel to the Gentiles. Though this seemed new and surprising to many, it was part of God’s plan all along—that those once far off would now be brought near.
So again, Paul prays for them. He wants them to know Christ so fully that they would not look elsewhere for truth or assurance. He also seeks to settle their hearts, because false teachers were troubling them. These teachers claimed that faith in Christ was not enough, and that believers must follow old ceremonies to truly belong to God.
But Paul makes it clear: their salvation was not accidental or incomplete. The gospel came to them because God had planned it from eternity. Their rescue from sin was entirely the work of His grace.
The Life That Follows (Chapter 4 and Beyond)
After showing what God has done, Paul turns to how believers should live. He teaches that Christ rules His church through the preaching of His Word. This is how the church is built up and kept strong.
From there, he describes the fruit of true faith. A life changed by grace will show itself in holiness, obedience, and love. Paul speaks both generally about the Christian life and specifically about how each person should live in their own calling.
