Duty or delight?

In church we sing. Is it our duty, or our delight? We read our Bibles, pray – (do you still?). Is it your duty, or your delight? As Christians, we encourage one another. We even try to share the Gospel with those who don’t believe – (do we?). Is that our duty, or our delight? This Sunday we read Isaiah 12. Here we hear a people that sings, serves and shares with great delight. What is their secret, what lies behind their delight?
