5:19 Speaking to yourselves. Ephesians 5:19-21 illustrates what the Spirit-filled life will be. Ephesians 5:19 applies not so much to congregational singing, as to “melody in your heart.” Such a life will be fruitful (Ephesians 5:9), active (Ephesians 5:16), understanding (Ephesians 5:17), joyful (Ephesians 5:19), thankful (Ephesians 5:20), and submissive (Ephesians 5:21). It will also be bold in witnessing (Acts 4:31).
