Tim Challies reminds us:
Songs are a powerful means of teaching. The melodies, rhythms, and rhymes that characterize songs make the words easier to remember. The best and most effective songs combine lyrics and music to cultivate feelings that complement the meaning.
All throughout history God’s people have used songs to teach. We can see this as early as Exodus 15 where Moses records the song Israel sang after crossing the Red Sea. It taught everyone who heard and sang it about God’s character in that great act of delivering his people. In the New Testament we encounter simple but important truths in the earliest Christian hymns.
Challies goes on to share the background to a famous hymn which instructs us on the doctrine of the church. It’s a hymn that is sung worldwide and has an interesting reason for being written. Read about The Church’s One Foundation here.
