Light and darkness is often used as allegories for good and evil or truth and lie. Here are some of the Bible verses with different aspects of light.
Then God commanded, “Let there be light”—and light appeared. (Genesis 1:3)
The people who walked in darkness have seen a great light. They lived in a land of shadows, but now light is shining on them. (Isaiah 9:2)
The light shines in the darkness, and the darkness has never put it out. God sent his messenger, a man named John, who came to tell people about the light, so that all should hear the message and believe. He himself was not the light; he came to tell about the light. This was the real light—the light that comes into the world and shines on all people. (John 1:5-9)
Jesus spoke to the Pharisees again. “I am the light of the world,” he said. “Whoever follows me will have the light of life and will never walk in darkness.” (John 8:12)
You are the source of all life, and because of your light we see the light. (Psalm 36:9)
“You are like light for the whole world. A city built on a hill cannot be hid. No one lights a lamp and puts it under a bowl; instead it is put on the lampstand, where it gives light for everyone in the house. In the same way your light must shine before people, so that they will see the good things you do and praise your Father in heaven. (Matthew 5:14-16)
Your word is a lamp to guide me
and a light for my path.
Now the message that we have heard from his Son and announce is this: God is light, and there is no darkness at all in him. If, then, we say that we have fellowship with him, yet at the same time live in the darkness, we are lying both in our words and in our actions. But if we live in the light—just as he is in the light—then we have fellowship with one another, and the blood of Jesus, his Son, purifies us from every sin. (1 John 1:5-7)
for anything that is clearly revealed becomes light. That is why it is said,
“Wake up, sleeper,
and rise from death,
and Christ will shine on you.”
However, the command I now write you is new, because its truth is seen in Christ and also in you. For the darkness is passing away, and the real light is already shining.
If we say that we are in the light, yet hate others, we are in the darkness to this very hour. If we love others, we live in the light, and so there is nothing in us that will cause someone else to sin. (1 John 2:8-10)
