'Light' in the Bible

in whom the god of this world hath blinded the minds of the unbelieving, that the light of the gospel of the glory of Christ, who is the image of God, should not dawn upon them .

Seeing it is God, that said, Light shall shine out of darkness, who shined in our hearts, to give the light of the knowledge of the glory of God in the face of Jesus Christ.

For our light affliction, which is for the moment, worketh for us more and more exceedingly an eternal weight of glory;

Be not unequally yoked with unbelievers: for what fellowship have righteousness and iniquity? or what communion hath light with darkness?

And no marvel; for even Satan fashioneth himself into an angel of light.
