'Light' in the Bible

among them the god of this world [Satan] has blinded the minds of the unbelieving to prevent them from seeing the illuminating light of the gospel of the glory of Christ, who is the image of God.

For God, who said, “Let light shine out of darkness,” is the One who has shone in our hearts to give us the Light of the knowledge of the glory and majesty of God [clearly revealed] in the face of Christ.

But we have this precious treasure [the good news about salvation] in [unworthy] earthen vessels [of human frailty], so that the grandeur and surpassing greatness of the power will be [shown to be] from God [His sufficiency] and not from ourselves.

For our momentary, light distress [this passing trouble] is producing for us an eternal weight of glory [a fullness] beyond all measure [surpassing all comparisons, a transcendent splendor and an endless blessedness]!

Do not be unequally bound together with unbelievers [do not make mismatched alliances with them, inconsistent with your faith]. For what partnership can righteousness have with lawlessness? Or what fellowship can light have with darkness?

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