Since there was no link here, I just punched in both names in the YouTube search engine to see what popped up. I think I found the right video, and to be honest, it was a giant question dodging waste of time.
Sproul did not answer the question posed to him, in a way that made any relevant sense to the question itself. He just gave some wordy retort about how God is grieved when the wicked are judged. OK. And the answer?
Naw. Next we have a parallel story set up to help us understand Driscoll and Sproul's position on the God of reformed theology being like a judge who was grieved to sentence his son to the penalty that he deserved. But what he forgot to include in his little allegory, was that if the judge was to represent the God of the reformed thinking, than that judge raised his son as a criminal, teaching him his entire life to do nothing but break the law, shaping and predestining him to become a criminal, so that when the day of judgement came, he was able to condemn him for the very crimes he bred his son to commit, so that the judge could receive the glory for the execution of his perfect justice. And the judge SHOULD have been grieved because he raised his son to do nothing but act as a transgressor. If he had tacked THAT on then we might have had a little bit of consistency with the reformed view.
I don't know much about Sproul, but I knew enough about Driscoll to have been leery. That name alone was worth running from.
