Remember, light is not so much what you directly see as that by which you see everything else. This is why in John’s Gospel, Jesus Christ makes the almost boastful statement “I am the light of the world” (John 8:12). Jesus Christ is the amalgam of matter and spirit put together in one place, so we ourselves can put it together in all places, and enjoy things in their fullness. It can even enable us to see as God sees, if that is not expecting too much.
