You [Gentiles] also, who are in Christ, after having heard the message of truth, the good news about your salvation, and [after] believing in Him, were sealed [i.e., as evidence of ownership] with the promised Holy Spirit. [or, "the Holy Spirit who brings promises"].

And you [Gentiles] were once [spiritually] dead because of your shortcomings and sins.

So, you Gentiles by birth should remember what you once were. You are called "Uncircumcision" by those who are called "Circumcision" [i.e., the Jews], (which refers to a physical procedure performed by people).

But now [that you are] in [fellowship with] Christ, you [Gentiles], who were once far away [from God], have been brought near [to Him] through the blood of Christ.

For Christ is [the source of] our peace. He made both [Jews and Gentiles] one people, and broke down the barrier wall of hostility that divided them,

by abolishing in His fleshly body the [entire Jewish] law of commandments contained in decrees. [This was] so that He could create in [unity with] Himself one new person [i.e., the church] out of the two peoples [i.e., Jews and Gentiles], thereby bringing about peace [between them].

And Christ came and preached peace to you [Gentiles], who were far away [from God], and peace to those [Jews] who were near [to Him].

For through Him we [Jews and Gentiles] both have access to the Father by means of one Holy Spirit.

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 is the reason that I, Paul, the prisoner of Christ Jesus on behalf of you Gentiles, [pray for you. See 3:14-19].

[Note: Paul here digresses from his prayer, begun in 1:15-16, to explain the circumstances of his being a prisoner on behalf of these Gentiles]. [I assume] you have heard about my commission [to minister] to you, which was given to me by God's unearned favor.

[It is] that God's secret plan [i.e., revealed in the Gospel preached to Gentiles. See verse 6] was made known to me by way of a revelation. [See Acts 9:15; 22:21]. I have already written to you [about this] briefly [i.e., probably a reference to 1:9ff].

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.

This favor of preaching the unfathomable riches of Christ to the Gentiles was given to me [even though] I am the least significant of all saints [i.e., God's holy people].

So, I tell you this, and insist [on it] by [the authority of] the Lord: Do not continue to live with worthless thoughts as [unconverted] Gentiles do.
