John 9:32
“Since the world began was it not heard that any man opened the eyes of one that was born blind.”
“If now ye acknowledge that God hears not sinners, and this Person has wrought a miracle, and such a miracle as no man ever wrought, it is clear that He has surpassed all things in virtue, and that His power is greater than belongs to man.” What then say they?
