OUR FATHER WHO REVEALED THE MYSTERY OF THE UNITY OF THE JEWS AND GENTILES IN CHRIST

Ephesians chapter 3 verse 4 says this;

 In reading this, then, you will be able to understand my insight into the mystery of Christ, 

The Apostle Paul, writing to the Ephesians, was explaining to them the nature of his mission as a Jew who was sent to them as gentiles.

He said that from the ancient past, the salvation of the gentiles was a mystery that was locked away so that no one could decipher the encoded plan of salvation for the Jews and the gentiles.

Paul reveals that he gained the understanding of this great mystery of God's grace being extending to the gentiles, through direct revelation by the Spirit of God and this revelation was the basis for his ministry.

The mystery, locked up as an enigma for eons, was that the Gentiles would become heirs in the same way that the Jews were and that the two groups would become one body and would share in the promises of Christ. 

This is the great mystery, is hinted at in Isaiah chapter 49 verse 5 - 6 that, written in the words of the coming Messaih, says;

And now the Lord says—he who formed me in the womb to be his servant to bring Jacob back to him and gather Israel to himself, for I am honored in the eyes of the Lord and my God has been my strength—he says:

 “It is too small a thing for you to be my servant  to restore the tribes of Jacob and bring back those of Israel I have kept.

I will also make you a light for the Gentiles, that my salvation may reach to the ends of the earth.”

Amen.
