Light serves a profound function in our lives. Receive too much or too little of it and you’ll experience both physical and emotional effects. I remember visiting Alaska in the summer and reading a book by sunlight at 2am in the morning. This was a pretty cool experience but it made it quite difficult to sleep at my normal times. I also have many friends who live in Seattle and talk about the lack of sunlight they receive on a regular basis. It’s not uncommon for a person to choose where she lives based on the light available in that state. Light affects everything.
It shouldn’t surprise us then that light serves as an important metaphor for spirituality. The apostle John heard Jesus explain firsthand that He Himself was the light of the world (John 8:12, 9:5). After years of reflecting on this, John would later teach us that “God is light; in him there is no darkness at all. If we claim to have fellowship with him and yet walk in the darkness, we lie and do not live out the truth” (1 John 1:5a-6).
