We move more deeply into our sermon series focused on how God provides comfort and hope to us, and make our way through the prophetic book of Isaiah. This week, in a text from Isaiah 42—I will keep you and call you to be. . . a light unto the Gentiles—we are offered the vivid metaphor of Light to consider in the context of thinking about comfort and hope. Taking on the calling of illuminating the world gives meaning to our lives and orients us toward hope.
