The Mystery of the Gospel – Ephesians 3:1-7
3 For this reason I, Paul, a prisoner of Christ Jesus on behalf of you Gentiles— 2 assuming that you have heard of the stewardship of God’s grace that was given to me for you, 3 how the mystery was made known to me by revelation, as I have written briefly. 4 When you read this, you can perceive my insight into the mystery of Christ, 5 which was not made known to the sons of men in other generations as it has now been revealed to his holy apostles and prophets by the Spirit. 6 This mystery is that the Gentiles are fellow heirs, members of the same body, and partakers of the promise in Christ Jesus through the gospel.
7 Of this gospel I was made a minister according to the gift of God’s grace, which was given me by the working of his power.
The Church is the keeper and herald of the gospel mystery. For most of the last two thousand years, the Church has done this keeping and heralding work under pressure. And, honestly, the pressure kept generations before us dependent on Christ and longing for Heaven. This passage proclaims the triumph of God in Christ over every power and principality.
