“And God said, Let there be light: and there was light.” Gen 1:3. And there light is ever since those words were spoken.
It is a very hard thing to escape the presence of light. Let’s say a lamp, placed in a room, is the only existing source of visible light and one wants to get away from it. He exits the room and realizes that some of its ray seeps out from the gap underneath the door. He stuffs some insulating materials, yet even then, he wouldn’t know if there is some light wave that penetrates through the door. Technically, the light visible to the human eye only covers the region of wavelength between 400-700 nm. The way physicists define light these days extend to any electromagnetic radiation emitted by any body of matter in any given temperature, so even your own body emits radiation. But that aside…
Can you recall an experience of being in complete darkness? When you switch the light off to go to bed, your eyes re-adjust to the new exposure and as the retinal chemistry progresses and completes, you see better. You can close your eyes, but through your eyelids you can see differences of light intensity. At night out in the countryside, there’s still the moon and the stars. Or what about when the sun is out during the day? No matter what you do and where you are, you are still exposed to its brightness (unless maybe if you’re working in an underground complex a couple stories below). The state of complete darkness is enough to make one go insane. Bottom line, when there is a source of light, you can blanket yourself, hide behind the couch, and you are still exposed to it. Light is everywhere, and it is inescapable. Moreover, light is imperative for any activity.
“And the city had no need of the sun, neither of the moon, to shine in it: for the glory of God did lighten it, and the Lamb is the light thereof.” Rev 21:23.
How would it be to live in a city where the light itself comes from God? I mean that ray that shines and envelopes every nanometer of your being is straightly derived from the presence of God Himself. It is the presence of God. All of your activities are done under the glory of God.
“And the nations of them which are saved shall walk in the light of it…” Rev 21:24.
“And there shall be no night there; and they need no candle, neither the light of the sun; for the Lord God giveth them light: and they shall reign for ever and ever.” Rev 22:5.
Perhaps this is what Enoch experienced when the Bible says he walked with God. He was living in the atmosphere of heaven, in the reality that God is present everywhere. I have entertained the notion of picturing Jesus walking by me everywhere as the definition of walking with God, and it has failed many times. I simply could forget that Jesus is present, and then sin enters. Enoch was living on earth as if he was already in heaven, and God just took him right to heaven.
Perhaps then light can be an object lesson for us. As much as I can’t escape light, I can’t escape God. As much as I need light to do any thing, I need God. As much as light is present, God is present.
