Colossians 3:15-17

And let the peace (soul harmony which comes) from Christ rule (act as umpire continually) in your hearts [deciding and settling with finality all questions that arise in your minds, in that peaceful state] to which as [members of Christ's] one body you were also called [to live]. And be thankful (appreciative), [giving praise to God always]. Let the word [spoken by] Christ (the Messiah) have its home [in your hearts and minds] and dwell in you in [all its] richness, as you teach and admonish and train one another in all insight and intelligence and wisdom [in spiritual things, and as you sing] psalms and hymns and spiritual songs, making melody to God with [His] grace in your hearts. And whatever you do [no matter what it is] in word or deed, do everything in the name of the Lord Jesus and in [dependence upon] His Person, giving praise to God the Father through Him.
