Final answer:
In Colossians 3:16, Paul advises that Christian worship songs should be imbued with the Word of Christ, wisdom of God, and gratitude in the worshippers' hearts.
Step-by-step explanation:
Paul instructs the Colossians that Christian worship songs sung in church are supposed to be filled with the 'Word of Christ,' 'wisdom of God,' and 'gratitude in hearts' as mentioned in Colossians 3:16. This scripture emphasizes that spiritual songs and hymns are not just musical expressions but should also serve to teach, encourage, and express thankfulness to God. It highlights the importance of letting the message of Christ dwell among the believers richly, leading to worship that encompasses teaching and admonishing one another with the truths of Scripture, all done with gratefulness.
