2 Corinthians 4:3-5

And even if our gospel is veiled, it is veiled to those who are perishing, in whose case the god of this world has blinded the minds of the unbelieving so that they might not see the light of the gospel of the glory of Christ, who is the image of God. For we do not preach ourselves but Christ Jesus as Lord, and ourselves as your bond-servants for Jesus’ sake.
