“And to make all men see what is the fellowship of the mystery, which from the beginning of the world hath been hid in God, who created all things by Jesus Christ:”
King James Version (KJV)
3:9 What is the fellowship of the mystery - What those mysterious blessings are whereof all believers jointly partake. Which was, in a great measure, hidden from eternity by God, who, to make way for the free exercise of his love, created all things - This is the foundation of all his dispensations.
Eph 3:9 And to make all [men] see. Jews as well as Gentiles. What [is] the fellowship of the mystery. The office or stewardship of this mystery. It was demonstrated in his apostleship to the Gentiles. Which from the beginning of the world hath been hid in God. It was from the beginning God's purpose to save the Gentiles by the gospel, but it had been kept hidden.
