Ephesians 3:2-7 NIV

[2] Surely you have heard about the administration of God’s grace that was given to me for you, [3] that is, the mystery made known to me by revelation, as I have already written briefly. [4] In reading this, then, you will be able to understand my insight into the mystery of Christ, [5] which was not made known to people in other generations as it has now been revealed by the Spirit to God’s holy apostles and prophets. [6] This mystery is that through the gospel the Gentiles are heirs together with Israel, members together of one body, and sharers together in the promise in Christ Jesus. [7] I became a servant of this gospel by the gift of God’s grace given me through the working of his power.
