2 Corinthians 4:4-6

4The god of this age has blinded the minds of unbelievers, so that they cannot see the light of the gospel that displays the glory of Christ, who is the image of God. 5For what we preach is not ourselves, but Jesus Christ as Lord, and ourselves as your servants for Jesus’ sake. 6For 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.
