John 9:3

3. Neither… this man… nor his parents Our Lord does not deny that they had sinned, but that they had sinned as the cause of his being born blind. Works of God We do not understand our Lord to say that the single object for which this man was born blind was, that Jesus might work a miracle upon him. God is a divine teacher; awakening, instructing, and developing the minds of men, by the phenomena around them, to a full knowledge, both scientific and spiritual, of his works in nature and in history. Both the excellencies and defects of nature, the ordinary and the extraordinary providences, furnish subjects of study as illustrations of God’s works and his dealings with a sinful race.
