Ephesians 3:3-9

and that by [divine] revelation the mystery was made known to me, as I have already written in brief. [Eph 1:9] By referring to this, when you read it you can understand my insight into the mystery of Christ, which in other generations was not disclosed to mankind, as it has now been revealed to His holy apostles and prophets by the [Holy] Spirit; [it is this:] that the Gentiles are now joint heirs [with the Jews] and members of the same body, and joint partakers [sharing] in the [same divine] promise in Christ Jesus through [their faith in] the good news [of salvation]. Of this [gospel] I was made a minister by the gift of God’s grace given me through the working of His power. To me, [though I am] the very least of all the saints (God’s people), this grace [which is undeserved] was graciously given, to proclaim to the Gentiles the good news of the incomprehensible riches of Christ [that spiritual wealth which no one can fully understand], and to make plain [to everyone] the plan of the mystery [regarding the uniting of believing Jews and Gentiles into one body] which [until now] was kept hidden through the ages in [the mind of] God who created all things.
