SOJ - The scripture at Deut. 18:20-22 regarding identification of a false prophet does NOT give any leeway for those who prophesy to be, in your words, "mistaken." Nor does it allow for the prophet to avoid his identification as false by saying, regarding that falsely prophesied, "It was a natural enough mistake to make (the societies own words)" Nor is there any room in that scripture to claim that which was poorly understood by the prophet is now being made more clear by "new light." And on and on in that vein the society attempts to cut itself slack when it screws up yet another prophecy - yet God did not cut those falsely prophecying such slack. There is NO ROOM in the cited scripture for ANY mistake on the part of the real prophet at ANY time. Can't you get a firm grasp on the obvious?
Further, the cited scripture INSTRUCTS Gods followers "do NOT be afraid of him." Yet the WTBTS enforces its false prophesies upon its member rank and file, threatening them with disfellowshipping if they do not preach their false prophecies. This is a black and white, up or down CHOICE presented to the followers of God BY GOD: choose between my instructions here, or follow and be afraid of the false prophet (which way leads to destruction). By choosing to continue to believe and follow the false prophet, the people MUST disobey God. And there's no way to slice and dice that scripture to make it say anything else. It is very clear that the blind are indeed following the blind.
How can you say you have any personal honor or morals when you knowingly follow a false prophet and encourage others to do so? Would you like a list of all the false prophecies authored by the GB in the last 120 years?
