sing.

"We have seen in effect that Calvin placed singing at the heart of his theology of the Church.  The reason is not far to seek.  To put it with the utmost simplicity: The Church is the place where the Gospel is preached; Gospel is good news; good news makes people happy; happy people sing.  But then, too, unhappy people may sing to cheer themselves up."
