God is light, and it is His plan that believers shine forth His light, becoming more like Christ every day. “You are all children of the light and children of the day. We do not belong to the night or to the darkness” (1 Thessalonians 5:5). God is the Creator of physical light as well as the Giver of spiritual light by which we can see the truth. Light exposes that which is hidden in darkness; it shows things as they really are. To walk in the light means to know God, understand the truth, and live in righteousness.
