Charles Spurgeon Commentary John 9:31

"We know that God heareth not sinners: but if any man be a worshipper of God, and do his will, him he heareth." — John 9:31 (ASV)

Now we know that God hears not sinners:

He meant men who are living in known sin, impostors and deceivers. Of course, God would not hear sinners of that kind.
