15 And let the peace of God rule in your hearts, to which also you were called in one body; and be thankful. 16 Let the word of Christ dwell in you richly in all wisdom, teaching and admonishing one another in psalms and hymns and spiritual songs, singing with grace in your hearts to the Lord. 17 And whatever you do in word or deed, do all in the name of the Lord Jesus, giving thanks to God the Father through Him.
