How does God open our spiritual eyes?

The process of opening spiritual eyes is a miraculous work of the Holy Spirit, who illuminates our hearts to understand God's truth (1 Corinthians 2:9-10). Just as Jesus performed a physical miracle by healing the blind man, He spiritually enlightens believers to perceive the reality of their salvation and the glory of God. This transformation leads to a sincere faith in Christ as the only means of redemption, affirming that without divine illumination, one remains spiritually blind and unable to grasp the gospel's significance.
