Ephesians 3:5-7

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.
