And God said, "Let there be light," and there was light. (Genesis 1:3)
God said, and there was - and this is how it is today and forever. Man thinks he can create the world the way he wants but it is only as God says it will be in the end. It is only God Who brings light into the world. Man does not like His light. It exposes his lies, and his evil intentions. So he seeks to counterfeit or snuff out the light. But that's impossible. Not only is God the creator of light but He, Himself is the light. All who want His true light may have it if they ask in humility and faith.
In the beginning was the Word, and the Word was with God, and the Word was God.
He was in the beginning with God.
All things were made through him, and without him was not any thing made that was made.
In him was life, and the life was the light of men.
The light shines in the darkness, and the darkness has not overcome it.
There was a man sent from God, whose name was John.
He came as a witness, to bear witness about the light, that all might believe through him.
He was not the light, but came to bear witness about the light.
The true light, which gives light to everyone, was coming into the world.
He was in the world, and the world was made through him, yet the world did not know him. (John 1:1-10)
And the city has no need of sun or moon to shine on it, for the glory of God gives it light, and its lamp is the Lamb. By its light will the nations walk, and the kings of the earth will bring their glory into it, (Revelation 21:23 - 24)
And night will be no more. They will need no light of lamp or sun, for the Lord God will be their light, and they will reign forever and ever. (Revelation 22:5)
From the beginning satan has tried to snuff out that light, or counterfeit it. But God separates the light from the darkness and makes all things clear.
And this is the judgment: the light has come into the world, and people loved the darkness rather than the light because their works were evil.
