Eph 3:1
3:1 For {1} this cause I Paul, {a} the prisoner of Jesus Christ
    for you Gentiles,

 (1) He maintains his apostleship against the offence of the
     cross, upon which he also makes an argument to confirm
     himself, affirming that he was not only appointed an
     apostle by the mercy of God, but was also appointed
     particularly to the Gentiles.  And this was to call them
     everywhere to salvation, because God had so determined this
     from the beginning, although he deferred a great while the
     manifestation of his counsel.
     (a) These words, "the prisoner of Jesus Christ", are taken
         passively, that is to say, "I, Paul, am cast into prison
         for maintaining the glory of Christ."

Eph 3:5
3:5 Which in {b} other ages was not made known unto the sons of
    men, as it is now revealed unto his holy apostles and
    prophets by the Spirit;

    (b) He does not mean that no one knew of the calling of the
        Gentiles before, but because very few knew of it.  And
        those that did know it, such as the prophets, had it
        revealed to them very obscurely, and by means of
        symbols.

Eph 3:10
3:10 {2} To the intent that now unto the principalities and
     powers in heavenly [places] might be known by the church
     the {c} manifold wisdom of God,

 (2) The unsuspected calling of the Gentiles was as it were a
     mirror to the heavenly angels, in which they might behold the
     marvellous wisdom of God.
     (c) God always had only one way to save men by: but it had
         various shapes and forms.

Eph 3:11
3:11 According to the {d} eternal purpose which he purposed in
     Christ Jesus our Lord:

     (d) Which was before all things.

Eph 3:14
3:14 {3} For this cause I bow my knees unto the Father of our
     Lord Jesus Christ,

 (3) He teaches by his own example that the efficacy of the
     doctrine depends upon the grace of God, and therefore we
     ought to join prayers with the preaching and hearing of the
     word.  And these are needful not only to those who are
     youngsters in religion, but even to the oldest also, that
     as they grow up more and more by faith in Christ, and are
     confirmed with all spiritual gifts, they may be grounded
     and rooted in the knowledge of that immeasurable love, with
     which God the Father has loved us in Christ.  And this is
     because the whole family, of which a part is already
     received into heaven, and part is yet here on earth,
     depends upon that adoption of the heavenly Father, in his
     only Son.

Eph 3:15
3:15 Of whom the whole {e} family in heaven and earth is named,

     (e) That entire people, who had but one household Father,
         and that is the Church which is adopted in Christ.

Eph 3:16
3:16 That he would grant you, according to the {f} riches of his
     glory, to be strengthened with might by his Spirit in the
     {g} inner man;

     (f) According to the greatness of his mercy.
     (g) See Ro 7:22.

Eph 3:17
3:17 That Christ may dwell in your hearts by faith; that ye,
     being rooted and grounded in {h} love,

     (h) With which God loves us, which is the root of our
         election.

Eph 3:18
3:18 May be able to comprehend with all saints {i} what [is] the
     breadth, and length, and depth, and height;

     (i) How perfect that work of Christ is in every part.

Eph 3:19
3:19 And to know the {k} love of Christ, which {l} passeth
     knowledge, that ye might be filled with all the {m} fulness
     of God.

     (k) Which God has shown us in Christ.
     (l) Which surpasses all the capacity of man's intellect, to
         comprehend it fully in his mind: for otherwise whoever
         has the Spirit of God perceives as much (according to
         the measure that God has given him) as is necessary for
         salvation.
     (m) So that we have abundantly in us whatever things are
         required to make us perfect with God.

Eph 3:20
3:20 {4} Now unto him that is able to do exceeding abundantly
     above all that we ask or think, according to the power that
     worketh in us,

 (4) He breaks forth into a thanksgiving, by which the Ephesians
     also may be strengthened and encouraged to hope for
     anything from God.
