2 Corinthians 4:6

6 For God, who said, “Let light shine out of darkness,” made his light shine in our hearts to give us the light of the knowledge of God’s glory displayed in the face of Christ.

2 Corinthians 6:14

14 Do not be yoked together with unbelievers. For what do righteousness and wickedness have in common? Or what fellowship can light have with darkness?

2 Corinthians 11:14

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