“Let the word of Christ dwell in you richly in all wisdome, teaching and admonishing one another in Psalmes, and Hymnes, and Spirituall songs, singing with grace in your hearts to the Lord.”
1611 King James Version (KJV)
3:16 Let the word of Christ - So the apostle calls the whole scripture, and thereby asserts the divinity of his Master. Dwell - Not make a short stay, or an occasional visit, but take up its stated residence. Richly - In the largest measure, and with the greatest efficacy; so as to fill and govern the whole soul.
Col 3:16 Let the word of Christ. The word that has been preached to you. Dwell in you. As in a temple. Richly in all wisdom. If we treasure it up richly we will have the divine wisdom in our hearts. Teaching and admonishing. Those having the indwelling word would have ability to teach. In psalms, hymns, and spiritual songs. Teaching and admonishing were to be present even in song. Song was to have another object than to please the ear. It was not for enjoyment, but for edification. The species of song are named here and in Eph 5:19. For the distinction, see PNT "Eph 5:19". Singing with grace in your hearts to the Lord. With Christ's grace in your hearts; that is, with hearts pervaded by the love of Christ.
