NOTE: reading my paraphrased summary below can give you an indepth knowledge of the content of this profound chapter of Ephesians.
Think about these things, ponder them, be blessed by them!
(Continuing here with God’s Master Plan:)
3:1-5 Because of this (which I have been writing to you), I, Paul, the prisoner of Christ Jesus–If indeed you had heard about the household-management of God’s grace which was given to me for your benefit. That is, I’m writing according to the revelation that was make known to me by the Lord, the mystery, which I have described to you before, and since you are reading them, you can again recognize my understanding of the mystery of Christ that fits together like pieces of a puzzle. This wisdom wasn’t known before to people, but now it has been make plain by his holy apostles and prophets functioning with the help of the Holy Spirit.
3:6-7 (And this is the mystery:) That the people of the nations, the Gentiles, are to be joint-heirs, joined together in one body, joint-sharers in the promise of Christ Jesus through the Gospel–which I became a minister of, according o the gift of the grace of God given to me by the working of His power.
3:8-9 To me, the least of all saints was given this grace (gift of enablement) to preach to the nations the unsearchable riches of Christ, and to bring to light what has been hidden from the ages in God–all the things created…
3:10-11 In order that the rich multifaced wisdom of God–according to the purpose of the ages which He made within Christ Jesus our Lord–might be made know to the rules and authorities in the heavenly realm…
3:12 In Whom (being in Jesus Christ) we have boldness and access (to God the Father) with confidence through His faith.
3:13 Therefore, I ask you not to be discouraged by my tribulations, which are for you, on your behalf–which is your glory (that is, it shows how much God cares for you that he allows me to go through such suffering on your behalf).
3:14-15 Because of this grace (this knowledge given to me by God freely so that I can minister it to you), I am continually bending my knees to the Father in prayer, Who is the father-source of every family named, whether now in heaven or on earth…
3:16-18 [And this is my prayer for you…] that He might give you, according to the measure of the riches of HIs glory, the gift of ongoing strengthening with (His) power poured by His Spirit into your inner man, so that Christ may thoroughly settle down comfortably without your hearts throuigh your ecercise of faith–and so that His love then established as a lasting foundation there–and in turn, so that you may be strong enough to understand with all the saints with is the breadth and length and height and depth [of God’s love and His wonderous plan for you and all believers]…
3:19 and as a result [of my answsered prayer for you] that you come to know in your experience the love of Christ which transcends, goes beyond all knowledge, in order that you may be filled up with all the fullness of God. [Awesome thought!]
3:20 Now to the One who is constandly able to do all things super-abundantly beyond what we are asking or even thinking, according to His power that is itself working within us–to Him be the glory in the Church and in Christ Jesus throughout all generations of the ages of the ages. Amen.
Now that’s a strong prayer, made perfectly within the context of the mystery Paul has made plain above. How can we walk in light of all of that? In joy, and fellowship with God and His Son, and in service.
