Shining in shadow

Isaiah speaks to a people sunk in darkness, and brings the promise of light. That promise, delivered with sweet certainty, comes to fulfilment in the arrival of Immanuel, the Christ, Jesus of Nazareth. That language of darkness is equally applicable to all men who are living without and apart from Christ Jesus, which is why we need to understand the lack of light (walking and living in deep and death-like darkness), the hope of light (God's gracious gift to benighted men), and the gift of light, which is God's own Son, come into the world for salvation.
