'Light' in the Bible

In him was life, and the life was the light of men.

And the light appears in darkness, and the darkness apprehended it not.

He came for witness, that he might witness concerning the light, that all might believe through him.

He was not the light, but that he might witness concerning the light.

The true light was that which, coming into the world, lightens every man.

And this is the judgment, that light is come into the world, and men have loved darkness rather than light; for their works were evil.

For every one that does evil hates the light, and does not come to the light that his works may not be shewn as they are;

but he that practises the truth comes to the light, that his works may be manifested that they have been wrought in God.

He was the burning and shining lamp, and ye were willing for a season to rejoice in his light.

Again therefore Jesus spoke to them, saying, I am the light of the world; he that follows me shall not walk in darkness, but shall have the light of life.

As long as I am in the world, I am the light of the world.

Jesus answered, Are there not twelve hours in the day? If any one walk in the day, he does not stumble, because he sees the light of this world;

but if any one walk in the night, he stumbles, because the light is not in him.

Jesus therefore said to them, Yet a little while is the light amongst you. Walk while ye have the light, that darkness may not overtake you. And he who walks in the darkness does not know where he goes.

While ye have the light, believe in the light, that ye may become sons of light. Jesus said these things, and going away hid himself from them.

I am come into the world as light, that every one that believes on me may not abide in darkness;
