15 “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, 16 do not cease giving thanks for you, while making mention of you in my prayers; 17 that the God of our Lord Jesus Christ, the Father of glory, may give you a spirit of wisdom and of revelation in the knowledge of Him. 18 I pray that the eyes of your heart [u]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,19 and what is the boundless greatness of His power toward us who believe. These are in accordance with the working of the strength of His might 20 which He brought about in Christ, when He raised Him from the dead and seated Him at His right hand in the heavenly places, 21 far above all rule and authority and power and dominion, and every name that is named, not only in this age but also in the one to come. 22 And He put all things in subjection under His feet, and made Him head over all things to the church, 23 which is His body, the fullness of Him who fills all in all.”
Spirit of wisdom and of revelation: Paul is not speaking of random revelations or hidden secrets from God but a deeper understanding of Jesus. Believers don’t need anything new from God, or more of His blessing. We simply need to grow in our understanding of all that we already have in Christ (see also 2 Peter 1:3-4; Ephesians 3:14-19).
Raised Him from the dead: God raised Christ from the dead, the act which authenticated the entirety of Christ’s salvific work. But when we believe in Jesus, we are also raised with Christ and seated with Him in the heavenlies. Because Christ was raised, we too are raised to new life (Ephesians 2:6).
The fullness of Him: The church is the fullness of Jesus. Each individual member expresses an aspect of Him. We are his hands, feet, eyes, and ears. Every believer is a unique expression of Christ.
