The Light of the World

I am the light of the world. What does that mean? In Genesis chapter 1, the earth is formless, void, and dark, and God says, “Let there be light.” What was formless was being formed; what was void began to be filled with life, and darkness was put on its heels. Jesus claims, "I alone take what is formless and form it, I alone fill voids with life, and I alone put darkness on its heels.”
