We can learn something from this, now thinking about it. What do we know in basic terms about light?:
It is dependent on a form of energy to radiate.
It casts out any form of darkness.
It reveals the scene of an environment all around.
It creates heat and stabilizes life.
This is remarkable, since I see a symbolism in creation pointing to God, and following Him.
What do we know about darkness, the absence of light?:
It depends on nothing.
It flees and hides when light draws near it.
You cannot see anything with it, total blindness.
Lack of light means lack of heat and life, just like space.
Remarkable how that points to those who depend on anything other than the light.
