What does it mean to have one's eyes opened to the gospel?

In 2 Corinthians 4:6, Paul articulates that God must shine light into our hearts for us to know the glory of God in the face of Jesus Christ. This act of illumination is a sovereign work of God that dispels spiritual blindness caused by sin and the influence of the enemy. Therefore, when one's eyes are opened to the gospel, they begin to recognize their own sinfulness, understand the sacrifice of Christ, and embrace the truth of salvation. This divine revelation is essential for faith in Christ, as it enables an individual to respond to the gospel message with repentance and belief.
