Norwegen doesn't really know his Bible very well Ding. He's been trying to give us quotes from Revelation (which is the end times), and they haven't happened yet.
As far as John 12:31? Again, Norwegen shows his ignorance yet again, here is what the verse actually says.
31 Now is the time for judgment on this world; now the prince of this world will be driven out.
It says the price of this world WILL be driven out, not that he has been.
