Paul calls himself a prisoner of Christ Jesus on behalf of the Gentiles and recalls that he received by revelation the stewardship of God's grace for them. The mystery that was not made known in other generations, but has now been revealed to his holy apostles and prophets by the Spirit, is this: the Gentiles are fellow heirs, members of the same body and partakers of the promise in Christ Jesus through the gospel.
Paul was made a minister of that gospel by the gift of God's grace, and he considers himself the very least of all the saints. His task is to preach to the Gentiles the unsearchable riches of Christ and to bring to light for everyone the stewardship of the mystery hidden for ages in God, who created all things. So through the church the manifold wisdom of God is now made known to the rulers and authorities in the heavenly places, according to the eternal purpose he realized in Christ, in whom we have boldness and access with confidence. Therefore he asks them not to lose heart over his sufferings for them, which are their glory.
Then Paul bows his knees before the Father, from whom every family in heaven and on earth is named, and prays that according to the riches of his glory he may grant them to be strengthened with power in the inner being through his Spirit, that Christ may dwell in their hearts through faith, and that, rooted and grounded in love, they may have strength to comprehend with all the saints what is the breadth, length, height and depth, and to know the love of Christ that surpasses knowledge, so as to be filled with all the fullness of God.
He closes with a doxology: to him who is able to do far more abundantly than all that we ask or think, according to the power at work within us, be glory in the church and in Christ Jesus throughout all generations, forever and ever.
