Glad I'm not the only one who had this reaction to the "guard dog" analogy. Not to beat a dead horse, but the first thing that came to mind when I first heard this talk was "... they just admitted that all the GB does is bark incoherently at anything that moves. They just ADMITTED that like an overzealous guard dog, they can't distinguish a real threat from an imagined threat."
They say Jehovah is a reasonable God. How reasonable is it for Jehovah to judge whether we should live or die based on whether or not we believed a group of men who have a 0% success rate of correctly interpreting Bible prophecy?
