Colossians 3:15-17:
15 And let the peace of Christ rule in your hearts, to which indeed you were called in one body. And be thankful. 16 Let the word of Christ dwell in you richly, teaching and admonishing one another in all wisdom, singing psalms and hymns and spiritual songs, with thankfulness in your hearts to God.
17 And whatever you do, in word or deed, do everything in the name of the Lord Jesus, giving thanks to God the Father through him.
