2 Corinthians 4:3-6

3And even if our gospel is veiled, it is veiled in them that perish: 4in 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. 5For we preach not ourselves, but Christ Jesus as Lord, and ourselves as your servants for Jesus’ sake. 6Seeing 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.
