Ephesians 3:3-6
3:3 that by revelation the divine secret was made known to me, as I wrote before briefly.
3:4 When reading this, you will be able to understand my insight into this secret of Christ.
3:5 Now this secret was not disclosed to people in former generations as it has now been revealed to his holy apostles and prophets by the Spirit,
3:6 namely, that through the gospel the Gentiles are fellow heirs, fellow members of the body, and fellow partakers of the promise in Christ Jesus.
