Passage
Seeing it is God, that said, Light shall shine out of darkness, who shined in our hearts, to give the light of the knowledge of the glory of God in the face of Jesus Christ.
Seeing it is God, that said, Light shall shine out of darkness, who shined in our hearts, to give the light of the knowledge of the glory of God in the face of Jesus Christ.
2 Corinthians 4:4 in whom the god of this world hath blinded the minds of the unbelieving, that the light of the gospel of the glory of Christ, who is the image of God, should not dawn [upon them].
2 Corinthians 4:5 For we preach not ourselves, but Christ Jesus as Lord, and ourselves as your servants for Jesus` sake.
2 Corinthians 4:6 Seeing it is God, that said, Light shall shine out of darkness, who shined in our hearts, to give the light of the knowledge of the glory of God in the face of Jesus Christ.
2 Corinthians 4:7 But we have this treasure in earthen vessels, that the exceeding greatness of the power may be of God, and not from ourselves;
2 Corinthians 4:8 [we are] pressed on every side, yet not straitened; perplexed, yet not unto despair;
The verse centers on "light", "darkness", "seeing", "said", "shall", "shine", "shined", and "hearts". It is saying that the contrast between light and darkness marks a real divide in how people respond to God's work.
The nearby context moves from verse 5's "For we preach not ourselves but Christ..." into verse 7's "But we have this treasure in earthen...", so "light" and "darkness" belong inside that flow. In 2 Corinthians context, the local focus is Christ, faith, and discipleship.
A plain takeaway is to answer the verse's own emphasis on "light" and "darkness" with trust shaped by these words, not by a vague optimism outside the passage.
