Eph 1:15-20 For this reason I too, having heard of the faith in the Lord Jesus which exists among you and your love for all the saints, do not cease giving thanks for you, while making mention of you in my prayers; that the God of our Lord Jesus Christ, the Father of glory, may give to you a spirit of wisdom and of revelation in the knowledge of Him. I pray that the eyes of your heart may be enlightened, so that you will know what is the hope of His calling, what are the riches of the glory of His inheritance in the saints, and what is the surpassing greatness of His power toward us who believe. These are in accordance with the working of the strength of His might which He brought about in Christ, when He raised Him from the dead and seated Him at His right hand in the heavenly places,
Paul reminds the Ephesians, and us today, that committing to prayer is vital. Even in his circumstances (Eph 3:1) he looks outside of himself and commits to keep the people of Ephesus in his prayers. He begins by acknowledging their faith in Christ and their love for one another. This is the foundation of our Christian faith. Loving, (or desiring) God and loving one another. (See Luke 10:27) Paul prays that the Father of Glory give them the spirit of wisdom and knowledge of the revelation of Him.
His prayer is that they will have the "eyes of their heart" opened to the riches of the glory of Christ. Hope, Glory, and Power. The hope of His calling, the riches of His glory, and the greatness of His power. To open the eyes of the heart is to be given the spirit of wisdom. The eye is a member of the body which allows us to see. Paul is encouraging them to "see" with their heart. John Gill: By the Spirit of God already, to see the exceeding sinfulness of sin; the insufficiency of their own righteousness; the beauty, glory, fullness, and suitableness of Christ, as a Saviour; the excellency, truth, and usefulness of the doctrines of the Gospel; in which their understandings were before dark, but now had light into them:
The work of salvation is not something we do on our own. All of God's work is done by His strength and not our own. It is His work done by His power and His strength brought about through His son Jesus Christ. The all sufficiency of God is primary for the believer's walk with Him and Paul expresses the power of God by reminding them of the power He displayed in the raising of Christ from the dead and seating Him at His right hand in heavenly places.
All of the strength that we need to accomplish His will in our life every day is given to us by the power of God. Be praise and glory to Him.
