2 Corinthians 4:6

4:6 For God, who said “Let light shine out of darkness,” is the one who shined in our hearts to give us the light of the glorious knowledge of God in the face of Christ.

2 Corinthians 4:18

4:18 because we are not looking at what can be seen but at what cannot be seen. For what can be seen is temporary, but what cannot be seen is eternal.
