Angels sing "Holy, holy, holy is the Lord God Almighty. The whole earth is filled with His glory." Did you know that we are surrounded by light and energy, but light only becomes visible when it shines upon something. So it is with the glory of God. The world is literally filled with the glory of Jesus, and we who know him reflect His glory. For those who are not facing the light source and can't see Him, it is "children of the light" who reflect his glory and who display the light for all the world to see.
