We know that God does not listen to sinners; but if someone reveres God and does his will, God listens to him.
In context
29We know that God has spoken to Moses; but this man — we don’t even know where he is from.” 30The man answered them, “Well, that is the astonishing thing: you don’t know where he is from, and yet he opened my eyes. 31We know that God does not listen to sinners; but if someone reveres God and does his will, God listens to him. 32Never in all time has it been heard that anyone opened the eyes of a man born blind. 33If this man were not from God, he could do nothing.”
