God's ever-changing New Light.
If the WT contradicts the Bible, then we should obey the WT because they have the Holy-Spirit in a way that the average Christian doesn't and their ways are beyond our comprehension. So we should submit at all costs because they have our best interests at heart, even though they show evidence of other religions which have done the same thing with tragic results. But they are pure and holy, whereas the other religions are not, despite Jeremiah 10:23.
Failed Prophecies
Despite their track record of failed prophecies, we should ignore what the Bible says regarding false prophets because they never actually said "Thus says Jehovah". Even though by proclaiming themselves to be God's mouthpiece, it's not the same as what the Bible says as regarding those speaking in God's name. Because they didn't utter that specific phrase. A mere technicality by human rules. They forget, God doesn't follow human rules.
