The Epistle to the Ephesians.

Ephesians 3; 4
 
Chapter 3, 4.
Chapter 1 revealed the counsels of God in Christ risen and seated on high, followed up by the apostle’s prayer to the God of our Lord Jesus; and chapter 2 showed us how grace has brought us in, not only as individuals, but collectively, and the temporary setting aside of Israel, believing Jews and Gentiles alike, to be Christ’s body and God’s habitation in the Spirit. Chapter 3 connects with the subject Paul’s special administration of this mystery or secret.
Therefore are the Gentiles the objects of grace in a way wholly unheard of in other generations, as now revealed to His holy apostles and prophets in the Spirit—the same power which builds all the saints together for God’s dwelling. It was by revelation made known that the Gentiles should be fellow-heirs, fellow-members of the body, and fellow-partakers of His promise in Christ through the gospel, of which Paul was become minister according to the gift of His grace given him according to the working of His power. This of course could not be, nor be revealed, till the cross had closed the Jewish system and opened the door in Christ ascended for the Creator of all things to make known heavenly counsels and ways in Him to any and everybody that believed. Equally clear is it that when Christ comes for His own to be with Him in the Father’s house, and subsequently appears to execute judgment on Babylon and the Beast, on the Antichrist and all other enemies, He will restore Israel specially and bless the Gentiles in general under His blissful reign over the universe.
Meanwhile the gospel where these distinctions are obliterated and unknown goes forth, and the unsearchable riches of the Christ announced, as Paul did pre-eminently and far beyond all prophecy. This was in order that now to the principalities and the authorities in the heavenlies might be made known through the church the manifold wisdom of God according to a purpose of the ages (or, eternal) which He purposed in Christ Jesus our Lord, in Whom we have boldness and access in confidence through the faith in Him. The apostle would not have them discouraged at his tribulations for them, it was their glory, which roused the enemy (verses 1-13).
“For this cause” (repeating the phrase which opens the chapter, and carrying out the parenthesis into a new prayer founded on its wondrous intimations) he bows his knees to the Father [of our Lord Jesus Christ, an addition favored by many MSS., Vv., etc.] of Whom every family in heaven and on earth is named. Here, however, it is not as in chapter 1 That a spirit of wisdom and revelation might be given to the saints to know the hope of His calling and the glory of His inheritance and the greatness of His power in Christ risen and exalted, but to be strengthened with power by His Spirit in the inner man, that Christ might dwell in their hearts through faith, rooted and grounded in love, that they might be able to apprehend with all the saints what is the breadth and length and depth and height (he does not say of what, but evidently of the mystery), and to know the love of the Christ which surpasses knowledge; that they might be filled unto all the fullness of God. It is not for spiritual intelligence of God’s counsels and of what God had wrought in Christ to give them effect, but for present power of the Spirit in realizing Christ dwelling in their hearts, and thus entering in fellowship with all the saints into the boundless glory, and His love deeper than the glory which will display it another day. Now to Him that is able to do far exceeding above all we ask or think, according to the power that worketh in us (and not only for us), to Him be the glory in the church in Christ unto all generations forever and ever. Amen (vss. 14-21).
Paul, the prisoner in the Lord, beseeches the saints on the ground of all he has made known, to walk worthily of the calling wherewith they were called, with all lowliness and meekness, with long-suffering, forbearing one another in love, using diligence to keep the unity of the Spirit in the joint bond of peace. This leads him to set forth unity fully: “one body and one Spirit, even as also ye were called in one hope of your calling; one Lord, one faith, one baptism; one God and Father of all, who is over all and through all, and in you [or, us] all” (vers. 1-6). The relationship determines the duty: what then must be ours, so blessed of God? It is easy to see that verse 4 sets out the vital, as verse 5 the professing, unity; while verse 6 is universal in its early clauses, yet the most intimate grace in the last. We are exhorted to be faithful in every case.
Next, the various workings in each for the blessing of all to Christ’s glory are shown in verse 7-16. All is founded on Him ascended on high, as this depended on His descending into the lower parts of the earth, and also ascending to the highest, that He might fill all things. He it is gave some apostles, and some prophets, and some evangelists, and some shepherds and teachers, for the perfecting of the saints, unto work of ministry, unto edifying of the body of Christ. What is the term of this? Until we all arrive at the unity of the faith and of the knowledge of the Son of God, at a full-grown man, at the measure of stature of the fullness of Christ. For His gracious aim is that we be no longer babes, tossed and carried about by every wind of the teaching [that is] in the sleight of men for the witness of error; but, holding truth in love, we may grow up into Him in all things, Who is the head, the Christ; from Whom the whole body, fitted and compacted together by every joint of supply, according to the effectual working in measure of each one part, works for itself the increase of the body unto its own edifying in love.
It is not here, as in 1 Corinthians 12, the Holy Spirit testifying in this creation (and hence by tongues, healings, etc.) to God’s glory in Christ, Who has defeated Satan before the universe. It is Christ in His love to His own sending down from His heavenly seat the gifts of His grace to His body and every several member. Thus here only we have the assurance that, while His members are on earth, His supplies of grace cannot fail. The foundation has been laid so well that it were folly to expect it re-laid; but all that perpetuates and edifies, it were unbelief to doubt till He come. With this goes the promise of the other Paraclete, the Holy Spirit, to abide Forever in and with us (John 14), Who guides into all the truth. Hence the very babes in Christ are said (1 John 2:2020But ye have an unction from the Holy One, and ye know all things. (1 John 2:20)) to have unction from the Holy One. No Christian need distrust.
Thereon the general exhortations proceed. They are warned against any allowance of their former walk as Gentiles, alienated from the life in every way, inward and outward. Not so did they learn the Christ, if albeit they heard Him and were taught in Him according as truth is in Jesus. What is this? Their having put away as to their former behavior the old man corrupt as to its lusts of deceit, and their being renewed in the spirit of their mind, and their having put on the new man which according to God was created in righteousness and holiness of the truth. Therefore putting away falsehood (this goes beyond lying) they were to speak truth, as being members one of another. They were not to allow continued anger. Instead of stealing they were to give, and to speak what was good for edifying, and not to grieve the Holy Spirit of God by Whom they were sealed for redemption’s day. So all bitterness and heat, wrath, clamour, and abusive language, with all malice, was to be put away from them; and they were to be kind one to another, compassionate, forgiving each other, even as God also showed them grace (verses 17-32).
“HE has always been sweet to my soul, but since I suffered for Him, His name has a sweeter fragrance than before. Oh, that every hair of my head and every member and bone of my body were a man, to witness a fair confession for Him.”
