Music is important. It is inspirational, and one of the greatest gifts God has given to us.
Music is also one of the most useful tools to bring the Word of Christ into our hearts (Colossians 3:16 – 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.)
Are you cheerful or happy (or want to be?) Sing praises to the Lord (James 5:13)!
