The second verse of "Joy to the World" builds on the theme of the first verse, where Isaac Watts anticipates the coming king. Now he exults in the reign of Christ. This also allows us to add the next foundation stone in constructing a biblical worldview based on this hymn. This truth is simple, yet profound -- Jesus reigns, it is good. Here is the second verse:
Joy to the World, the Savior reigns!
Let men their songs employ;
While fields and floods, rocks, hills and plains
Repeat the sounding joy...
All that is good, noble, and excellent in life stems from the glory and goodness of God, not from any other source. If Jesus reigns, joy is the response that fits. This flies in the face of conventional religion and wisdom, in which various circumstances determine one’s sense of well-being. Psalm 98 again provides the basis for these thoughts.
