Ephesians 3:3-6

3that the mystery was made known to me by revelation, as I wrote before briefly.

4When you read this, you can understand my insight into the mystery of Messiah—

5which was not made known to the sons of men in other generations, as it has now been revealed by the Ruach to His holy emissaries and prophets.

6This mystery is that the Gentiles are joint heirs and fellow members of the same body and co-sharers of the promise in Messiah Yeshua through the Good News.
