'Darkness' in the Bible

The light shines in the darkness, and the darkness hasn't overcome it.

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

Again, therefore, Jesus spoke to them, saying, "I am the light of the world. He who follows me will not walk in the darkness, but will have the light of life."

Jesus therefore said to them, "Yet a little while the light is with you. Walk while you have the light, that darkness doesn't overtake you. He who walks in the darkness doesn't know where he is going.

I have come as a light into the world, that whoever believes in me may not remain in the darkness.
