The imagery of light and darkness is a common theme in Isaiah, and in chapter 60 it takes on special significance. The prophet sees a time when the darkness that has enveloped Jerusalem will give way to a brilliant light that shines for all to see. This light is not just an external phenomenon, but a symbol of the inner radiance that comes from being in God's presence. The chapter speaks of the people's rejoicing, not because of their earthly wealth, but because of their restored relationship with God. For Christians, this chapter is a reminder that our hope is not in worldly things, but in the light of Christ, which shines in our hearts and empowers us to shine forth for the world to see.
