2 Corinthians 4:6

Seeing it is God, that said, Light shall shine out of darkness [Genesis 1:3; Isaiah 60:1-2], who shined in our hearts, to give the light of the knowledge of the glory of God in the face of Jesus Christ. [From such passages as 1 Corinthians 2:6-7; 1 Corinthians 4:16; 1 Corinthians 11:1; 1 Thessalonians 1:6; 1 Thessalonians 2:4; 1 Thessalonians 3:9; Galatians 4:12; Philippians 3:17; Paul might have been accused of preaching himself; but he had preached himself as a servant (1 Corinthians 9:19). Paul's rivals had preached themselves and had sought to make the preaching a contest between him and them. Paul declines this contest, and declares that it is his business to reflect the light of Christ which has shone in his heart; for God sent his Son to be the light of earth's darkness. The apostle here alludes to the glorified face of the Christ which appeared to him on the way to Damascus. After such a vision it was impossible that Paul could look upon himself as any other than a reflector of the true Light which was sent from God. It was also impossible that he should regard the face of Moses as comparable with it. Moreover, the prophecy spoke of but one light, and took no account of Moses.]
