'Light' in the Bible

In their case, the god of this world has blinded the minds of those who do not believe to keep them from seeing the light of the glorious gospel of the Messiah, who is the image of God.

For God, who said, "Let light shine out of darkness," has shone in our hearts to give us the light of the knowledge of God's glory in the face of Jesus the Messiah.

This light, temporary nature of our suffering is producing for us an everlasting weight of glory, far beyond any comparison,

Stop becoming unevenly yoked with unbelievers. What partnership can righteousness have with lawlessness? What fellowship can light have with darkness?

And no wonder, since Satan himself masquerades as an angel of light.
