Ephesians 3:8, 10, 16

Unto me, who am less than the least of all saints, is this grace given, that I should preach among the Gentiles the unsearchable riches of Christ

to the intent that now unto the principalities and powers in heavenly places might be known by the church the manifold wisdom of God

that he would grant you, according to the riches of his glory, to be strengthened with might by his Spirit in the inner man
