How does Christ's work result in spiritual sight for believers?

The result of Christ's work is illustrated profoundly in the healing of the blind man in John 9. When the man is healed, he gains not only physical sight but also spiritual insight into his own sinful condition and the glory of Christ. Prior to this miracle, the man had no awareness of his blindness, representing humanity's spiritual state. Once healed, he acknowledges Christ, which symbolizes the opening of the eyes of believers to see their need for a savior and the magnificence of God's grace. This transformative work of Christ reveals to us that all our righteousnesses are as filthy rags (Isaiah 64:6) and that our hope lies solely in Him. In essence, spiritual sight helps believers recognize their dependence on the perfect work of Christ for acceptance before God.
