Now you are using science to demonstrate what Jesus must do?
Weren't you using science when you said there were time-keeping devices? Don't we use science to demonstrate most aspects of nature? Jesus created a world that can be investigated using principles of knowledge to increase our understanding. If that were not so, then how could we know that the sun and moon are even physical creations now?
Jesus is the Light. There is no Dark side of the moon or planet with regard to the Light of Jesus.
Yet the passage is clear that there was both evening and morning, and that was after the darkness and light were separated. So, can you apply that to Jesus? Are you saying that there was some darkness in Him, and that His darkness and His lightness were somehow separated? Please explain how Jesus, being only light, can be both dark and light.
In addition, today the world spins. It might or might not have been spinning when first created (we don't know, since the bible doesn't say), but once the sun was created and set over the daylight, I think we wold both agree that the world was spinning by that time. If darkness was separated from the light, Gen 1:4, then there must have been some places where there was light and some places where there was no light. This was after the Spirit of God moved over the face of the waters, and after light was created. It seems natural to assume that the reason there were periods of darkness and periods of light on the earth at this point was because the light (not part of the earth) was present on one side of the earth, and that darkness was present (or light was absent) over the other side of the earth. There are two ways we know of for such a system to work.
1. That the earth spins while the light source is relatively fixed in space, or
2. That the earth is fixed and the light source progresses around it.
Since the latter doesn't comport with how the solar system works today, the former seems much more tenable. But I can't say for sure based on the information given in the text. Just in case we might have something wrong, let's try your way of understanding the light/dark/earth system.
1. Jesus is the light
2. Jesus might also be the dark, but I'll wait for you to clarify
3. The earth is not spinning
4. Therefore Jesus is going around the earth once per day, or once per 24 hours, at least until the sun is created to relieve Jesus of His job, at which time the earth starts spinning and going around the sun. Today the earth is somewhere around 25,000 miles in circumference. If Jesus is going around the earth once every 24 hours, assuming the earth today is the same size as it was back then, Jesus was traveling at a little over 1000 miles per hour, assuming He was at the surface of the earth, but probably quite a bit faster, because He was higher in altitude.
I'm being a little facetious there, but I'm having some difficulty understanding why Jesus being the light of the world would result in any darkness at all, since "in Him is no darkness, nor shadow of turning"? And why, since there is no shadow of turning, would Jesus be spinning around the earth at such a high rate of speed (though, certainly, Jesus would be able to travel that fast without too much trouble).
That light was more than a physical substance. That light was there before the Sun, Moon, Stars. It has a supernatural aspect. In the new Heaven and Earth there will be no Moon and Stars and Sun. God will again be the only light as he was in Day 1.
All things that God made have some supernatural aspect, wouldn't you agree? But since God made light on Day 1, and Jesus is eternal, how could Jesus be that light?
To you as well!
