that the God of our Lord Jesus Christ, the glorious Father, will give you a spirit [i.e., a disposition] of wisdom and revelation [or, "give you the spiritual gifts of wisdom and revelation"], so you can have full knowledge of God.

So then, you [Gentiles] are no longer foreigners and aliens [i.e., to God's promises. See verse 12], but you are fellow-citizens with the saints [i.e., God's holy people], and are part of God's family.

This secret plan is that the Gentiles [now] share in the inheritance along with us [Jews], and are fellow-members of the body [i.e., the church], and that they share, along with us [Jews], in the promise of the Gospel, in [fellowship with] Christ Jesus.

The One who descended [i.e., from heaven to earth] is the same One [i.e., Christ] who also ascended high above the all the heavens, so that He could fill the entire universe [with His presence]).

[This is to be done] until we all [eventually] arrive at unity of the faith and full knowledge of the Son of God; at complete [spiritual] maturity; at the [full] height of Christ's [spiritual] stature.

Do not let anyone deceive you with empty words, for because of such things, the wrath of God will fall upon people who are disobedient [to Him].

[This is] so He could present the church to Himself in all her splendor, without any kind of stain or wrinkle, but that she should be holy and without [moral] flaw.

You people should put on the full armor of God, so that you will be able to withstand the devil's schemes.

Therefore, put on the full armor of God, so that you can withstand [the devil, See verse 11] when the evil day comes. And, after you have done everything you can, still remain standing firm [in the faith].
