'Light' in the Bible

For once you were darkness, but now you are light in the Lord. Live as children of light,

for the fruit that the light produces consists of every form of goodness, righteousness, and truth.

But everything that is exposed to the light becomes visible,

for the light is making everything visible. That is why it says, "Wake up, sleeper! Arise from the dead, and the Messiah will shine on you.''
