 In John 12, he said this, I have come as a light into the world that whoever believes in me should not abide in darkness. That was true. He came into the world to be the light. There was a moment when Christ came into the world at his incarnation. We read in John 1 that he came as the light of the world. Now, notice what Jesus says in John chapter 9. Listen carefully. He said, as long as I am in the world, I am the light of the world.
