There is an old line in a hymn that goes like this:
“Let those refuse to sing
Who never knew our God
But children of the heavenly King
May speak their joys abroad.
To our ears, it sounds old fashioned. But think about it.
Who refuses to sing in our day? I could name a few: Richard Dawkins, Daniel Dennett, and a few others. Their works ooze ascerbic joylessness. The greatest tragedy is to live without knowing why you are alive.
As G.K. Chesterton put it, for the Christian joy is central and sorrow is peripheral, for the essential questions of life have been answered. You can’t really argue with the joy of the Lord. It just comes down.
