Paul introduces himself as an apostle of Christ Jesus by the will of God and greets the saints, the faithful in Christ, with grace and peace. Then he bursts into praise: blessed be the God and Father of our Lord Jesus Christ, who has blessed us in Christ with every spiritual blessing in the heavenly places.
The praise moves through the work of the Father, the Son and the Spirit. The Father chose us in Christ before the foundation of the world to be holy and blameless, and predestined us for adoption as his sons, according to the purpose of his will, to the praise of his glory. In the Son we have redemption through his blood, the forgiveness of sins, according to the riches of his grace. God made known the mystery of his will: to unite all things in Christ, things in heaven and on earth. In him we have also obtained an inheritance, and those who believed were sealed with the promised Holy Spirit, who is the guarantee of our inheritance until we acquire possession of it.
Next Paul gives thanks because he has heard of their faith in the Lord Jesus and their love toward all the saints, and he does not cease to pray for them. He asks that the God of our Lord Jesus Christ give them a spirit of wisdom and revelation in the knowledge of him, that the eyes of their hearts be enlightened so they may know the hope of his calling, the riches of his glorious inheritance in the saints and the immeasurable greatness of his power toward us who believe.
That power is the same that God worked in Christ when he raised him from the dead and seated him at his right hand in the heavenly places, far above all rule, authority, power and dominion. He put all things under his feet and gave him as head over all things to the church, which is his body, the fullness of him who fills all in all.
