It is in [fellowship with] Christ that we [Jewish Christians] also were selected as [God's] inheritance [i.e., to receive His never ending blessings], having been predetermined according to the plan of God, who works out everything in harmony with what He wants.

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.

All of us [Jews] also once lived among such people, fulfilling the improper cravings of our physical being and doing what our bodies and minds desired. In this natural [unconverted] state we were deserving of [God's] wrath, just like the rest [of mankind].

restored [spiritual] life to us with Christ, even though we were [spiritually] dead because of our sins --- it is by God's unearned favor that you have been saved.

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.

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].

[I am] assuming that you have heard Him [i.e., through the Gospel message] and were taught the truth that is in [harmony with] Jesus.

You were [taught] to put away [the conduct of] your former lifestyle, your old person who is being corrupted by deceitful desires,

And do not grieve God's Holy Spirit by whom you were sealed [i.e., given evidence of God's ownership] until the day of redemption [i.e., until you receive your new body in heaven. See 1:14].

for you people were once darkness [i.e., when living in sin], but now you are light in [fellowship with] the Lord. [So], live like people who belong to light [i.e., who live godly lives],
