Ephesians 3:8-12

To me, who am less than the least of all the saints, this grace was given, that I should preach among the Gentiles the unsearchable riches of Christ, and to make all see what is the fellowship of the mystery, which from the beginning of the ages has been hidden in God who created all things through Jesus Christ; to the intent that now the manifold wisdom of God might be made known by the church to the principalities and powers in the heavenly places,  according to the eternal purpose which He accomplished in Christ Jesus our Lord, in whom we have boldness and access with confidence through faith in Him.
