Light of the world

John 8:12 Again Jesus spoke to them, saying, "I am the light of the world. Whoever follows me will not walk in darkness, but will have the light of life."
2Corinthians 4:3-4 And even if our gospel is veiled, it is veiled to those who are perishing.   In their case the god of this world (Satan) has blinded the minds of the unbelievers, to keep them from seeing the light of the gospel of the glory of Christ, who is the image of God.
