Therefore I also, after I heard of your faith in the Lord Jesus and your love for all the saints, do not cease to give thanks for you, making mention of you in my prayers: that the God of our Lord Jesus Christ, the Father of glory, may give to you the spirit of wisdom and revelation in the knowledge of Him, the eyes of your understanding being enlightened; that you may 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 exceeding greatness of His power toward us who believe, according to the working of His mighty power which He worked in Christ when He raised Him from the dead and seated Him at His right hand in the heavenly places, far above all principality and power and might and dominion, and every name that is named, not only in this age but also in that which is to come.
And He put all things under His feet, and gave Him to be head over all things to the church, which is His body, the fullness of Him who fills all in all.
There are two prayers that the Apostle Paul prays over the church in Ephesus regularly this one and Ephesians 3:14-21. I have heard many preachers, including Kenneth Hagin, talk about the benefits of praying these prayers over yourself and your loved ones. Of course sincere prayer is always hugely beneficial to us but another benefit is that through repeating these prayers out loud we can renew our mind to the immense truths present in them.
Looking at this passage what stands out to me is the description of Jesus' total dominion and power that has been transferred to us. Notice how Paul states that Jesus' power is working "toward us" and that he refers to this dominion as our "inheritance"! Not to mention that he states we as the church are "His body" which mean that we are in the same position as Jesus Christ!
We need to recognize our position of dominion and authority in Christ!
If you look at your life and there seems to be no evidence of this dominion then I recommend praying this prayer daily. By praying you activate the power of God in your life allowing Him to bring what is true in the spiritual realm to pass in the physical realm (Romans 4:17) and by speaking the Word of God out loud you begin the process of renewing your mind (Romans 8:5; 12:2) and building your faith (Romans 10:17) to walk in the dominion and power that is available to you.
