I pray that the eyes of your heart may be enlightened in order that you may know the hope to which he has called you, the riches of his glorious inheritance in his holy people, and his incomparably great power for us who believe. That power is the same as the mighty strength he exerted when he raised Christ from the dead and seated him at his right hand in the heavenly realms, far above all rule and authority, power and dominion, and every name that is invoked, not only in the present age but also in the one to come. And God placed all things under his feet and appointed him to be head over everything for the church, which is his body, the fullness of him who fills everything in every way.
Paul prays that we may have a kind of “spiritual eyesight” whereby we may know 1) the hope to which we are called in our salvation, 2) the inheritance that we have received in our call to salvation, and 3) the power to live out our call of salvation.
The last item is of immense practical import. The power that Paul mentions is God’s life-giving power available to all believers because of and through the resurrection of Christ. He claims God’s greatest display of power was Jesus’ resurrection (Eph 1:22 is an allusion to Ps 110:1, quoted more often in the NT than any other OT text, and Ps 8:6; see also 1 Cor 15:25-28 and Heb 1:13-2:9).
In this divine display of incomparable power, Paul goes so far as to claim that Jesus trumps not only all religious figures of his day, but also all those in the future (Eph 1:21). This is an exclusive claim that Jesus is greater than all other religious and political figures of all time! Whatever layers of authorities there are in heaven and on earth, Jesus Christ sits above them all (Eph 1:21-22). He outranks and outflanks every human or angelic presence because of the resurrection. Moreover, Jesus Christ exercises universal and comprehensive lordship over the church and every member in it. He “fills everything in every way.”
