“Again Jesus spoke to them, saying, ‘I am the light of the world. Whoever follows me will not walk in darkness, but will have the light of life.'” John 8:12 ESV
The light of the world. Is that important?
Without light nothing can be seen. With light, all things are seen. Don’t believe me? Let’s see what science has to say about it. This excerpt comes from the www.physicsclassroom.com. Check it out:
The bottom line is: without light, there would be no sight. The visual ability of humans and other animals is the result of the complex interaction of light, eyes and brain. We are able to see because light from an object can move through space and reach our eyes. Once light reaches our eyes, signals are sent to our brain, and our brain deciphers the information in order to detect the appearance, location and movement of the objects we are sighting at. The whole process, as complex as it is, would not be possible if it were not for the presence of light. Without light, there would be no sight.
If you were to turn off the room lights for a moment and then cover all the windows with black construction paper to prevent any entry of light into the room, then you would notice that nothing in the room would be visible. There would be objects present that were capable of being seen. There would be eyes present that would be capable of detecting light from those objects. There would be a brain present that would be capable of deciphering the information sent to it. But there would be no light! The room and everything in it would look black. The appearance of black is merely a sign of the absence of light. When a room full of objects (or a table, a shirt or a sky) looks black, then the objects are not generating nor reflecting light to your eyes. And without light, there would be no sight.
I love this thought process about light. It is so important to all of us and Jesus shares that He is that, that is so important to us. I once was blind and now I see. Without light (Jesus) you can’t see. With light (Jesus) you can see. There are three separate instances of Jesus healing the blind in the Bible. Plus Ananias healed Saul/Paul of his blindness in Acts. Of all the ailments of the world, why would blindness be focused on so much?
I think it is because Jesus is the light. Without light you can’t see. Though it took a few years for science to catch up with the Bible, we can all know that truth now. Such a beautiful picture. And one of my favorite songs uses this language too.
