The blindness of the man born blind was not due to his sin, nor that of his parents, “but that the works of God should be revealed in him.” When we were all born, we were tied with the original sin. Despite this, we were not born blind. However, search carefully, for we were actually born blind. Who was not born blind? I mean the blindness of the heart. But the Lord Jesus who created the eyes and heart can heal both.” (Saint Augustine)
