The Bible sales like 1 million copies a week (receipts: http://answers.yahoo.com/question/in...0081943AAvtnFx) so his single would have great opening sales. As far as longevity, I'm not sure. During the Ray of Jerusalem, Confessions On The Cathedral and Like A Pastor eras he was unstoppable but who knows now. I'd say 500k opening week, 3x platinum in the US and 6 million WW.
