Nobody can quite agree on what exactly happened, but something went down on Friday when Mark Driscoll brought a carload of his books to John MacArthur’s Strange Fire Conference and started sharing his beliefs on the Holy Spirit—beliefs that are decidedly different from MacArthur’s. Things got dicey when security asked Pastor Driscoll to stop handing out his books. And then, depending on you ask, Pastor Driscoll either let security keep all his books or had them all confiscated.
