1 FOR THIS reason [because I preached that you are thus built up together], I, Paul, [am] the prisoner of Jesus the Christ for the sake and on behalf of you Gentiles–2 Assuming that you have heard of the stewardship of God’s grace (His unmerited favor) that was entrusted to me [to dispense to you] for your benefit,3 [And] that the mystery (secret) was made known to me and I was allowed to comprehend it by direct revelation, as I already briefly wrote you.4 When you read this you can understand my insight into the mystery of Christ. 5 [This mystery] was never disclosed to human beings in past generations as it has now been revealed to His holy apostles (consecrated messengers) and prophets by the [Holy] Spirit.6 [It is this:] that the Gentiles are now to be fellow heirs [with the Jews], members of the same body and joint partakers [sharing] in the same divine promise in Christ through [their acceptance of] the glad tidings (the Gospel).7 Of this [Gospel] I was made a minister according to the gift of God’s free grace (undeserved favor) which was bestowed on me by the exercise (the working in all its effectiveness) of His power.8 To me, though I am the very least of all the saints (God’s consecrated people), this grace (favor, privilege) was granted and graciously entrusted: to proclaim to the Gentiles the unending (boundless, fathomless, incalculable, and exhaustless) riches of Christ [wealth which no human being could have searched out],
Paul mentions that through the Holy Spirit, the revelation he brings has never been relayed to the followers before. He tells the Ephesians that Christ’s salvation comes to all people, not just a certain race. The Jews and Gentiles are the same in His eyes.
Paul was made a minister according to the free grace of God. This grace was given to Paul by the exercise of His power.
