'Light' in the Bible

In whom the god of this world hath blinded the minds of them which believe not, lest the light of the glorious gospel of Christ, who is the image of God, should shine unto them.

For God, who commanded the light to shine out of darkness, hath 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 but for a moment, worketh for us a far more exceeding and eternal weight of glory;

Be ye not unequally yoked together with unbelievers: for what fellowship hath righteousness with unrighteousness? and what communion hath light with darkness?

And no marvel; for Satan himself is transformed into an angel of light.
