Because of this, I, Paul, a prisoner of Christ Jesus for you Gentiles – if, as I suppose, you have heard of the stewardship of God’s grace that was given to me for your benefit, namely, that the mystery was made known to me by revelation, as I have written briefly earlier.  When you read this you can understand my insight into the mystery of Christ, which was not made known to human beings in other generations as it has now been revealed to his holy apostles and prophets by the Spirit, that the Gentiles are coheirs, members of the same body, and copartners in the promise in Christ Jesus through the gospel.

Ephesians 3:1-6
