What does the image of light and a lamp tell us about God's kingdom? Lamps in the ancient world served a vital function, much like they do today. They enable people to see and work in the dark and to avoid stumbling. The Jews also understood "light" as an expression of the inner beauty, truth, and goodness of God. In his light we see light ( Psalm 36:9). His word is a lamp that guides our steps (Psalm 119:105). God's grace not only illumines the darkness in our lives, but it also fills us with spiritual light, joy, and peace. Jesus used the image of a lamp to describe how his disciples are to live in the light of his truth and love. Just as natural light illumines the darkness and enables one to see visually, so the light of Christ shines in the hearts of believers and enables us to see the heavenly reality of God's kingdom. In fact, our mission is to be light-bearers of Christ so that others may see the truth of the gospel .
