Ephesians 4:17-24 - Appeal For New Behavior
17 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. 18 Their understanding [of spiritual things] is darkened and excluded from the [spiritual] life that God gives, because of the ignorance in their minds and the stubbornness in their hearts. 19 They have stopped caring [i.e., about morality], so God has abandoned them to lives of unrestrained indecency and to engage in all kinds of [moral] impurity, with a constant desire for more.
20 But you people did not learn Christ that way [i.e., the above described life is not compatible with a commitment to Christ]. 21 [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. 22 You were [taught] to put away [the conduct of] your former lifestyle, your old person who is being corrupted by deceitful desires, 23 and to be renewed in your inner person. 24 And you should put on the new person who has been [re-] created to be like God in true righteousness and holiness.
12 So, as God's elect [i.e., His people], holy and dearly loved [by Him], clothe yourselves with a heart of compassion, kindness, humility, gentleness and patience. 13 Tolerate one another's [weaknesses] and forgive each other if anyone [of you] has a complaint against someone else. You should forgive people just as the Lord forgave you. 14 And beyond all these things, clothe yourselves with love, which binds these things together in complete [unity]. 15 You should let the peace given by Christ rule in your hearts, since you people were called [to be at peace] in one body [i.e., the church]; and you should be thankful. 16 You should let the message of Christ live in you abundantly [i.e., as individuals and collectively]. Use [much] wisdom in teaching and warning one another with psalms, hymns and spiritual songs, singing with favor [i.e., with thankfulness] in your hearts toward God. 17 And whatever you do, whether in [your] words or actions, do everything in the name [i.e., by the authority] of Christ, giving thanks to God the Father through Him.
