How do we know that Jesus heals spiritual blindness?

The narrative in John 9, where Jesus heals a man who was born blind, serves as a profound illustration of His authority to grant spiritual sight. This man’s physical blindness mirrors the spiritual blindness of humanity before encountering Christ. Just as the man could not initiate his own healing, we too are spiritually incapable of recognizing our need for God without His divine intervention. The miracle demonstrates that only through Christ’s illuminating grace can our eyes be opened to perceive God’s holiness, justice, and mercy.
