For this cause I Paul, the prisoner of Jesus Christ for you Gentiles, If ye have heard of the dispensation of the grace of God which is given me to you-ward: How that by revelation he made known unto me the mystery; (as I wrote afore in few words, Whereby, when ye read, ye may understand my knowledge in the mystery of Christ) Which in other ages was not made known unto the sons of men, as it is now revealed unto his holy apostles and prophets by the Spirit; That the Gentiles should be fellowheirs, and of the same body, and partakers of his promise in Christ by the gospel: Whereof I was made a minister, according to the gift of the grace of God given unto me by the effectual working of his power. Unto me, who am less than the least of all saints, is this grace given, that I should preach among the Gentiles the unsearchable riches of Christ; ~ Ephesians 3:1-8 KJV

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– 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, [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. When you read this you can understand my insight into the mystery of Christ. [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. [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). 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. 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], ~ Ephesians 3:1-8 AMP
