The contrast between darkness and light is a prominent image in the Bible's presentation of Jesus the Messiah. "The people who walked in darkness have seen a great light; those who dwelt in the land of the shadow of death, upon them a light has shined" (Isaiah 9:2). "In [Jesus] was life, and the life was the light of men. And the light shines in the darkness, and the darkness did not comprehend it" (John 1:4-5).
It's our privilege as followers of Jesus to be His light-bearers today. Paul urged the Christians in Philippi to become "blameless and harmless, children of God without fault in the midst of a crooked and perverse generation, among whom you shine as lights in the world" (Phil. 2:15). Instead of being afraid or oppressed by the spiritual darkness around us, we can rely on the grace that God gives His children to shine for Him.
