The wtbts places themselves as the dispensers of the food that comes from God - indeed they even say that they are part of the makeup of "the Christ", taking up where He and the apostles left off - the source of God on earth today
Jesus taught that which came from God, and if He was wrong about stuff that He had said, do you think He would be truthful about it - even step down?
The wtbts teaches what they imagine should come from God, and arrogantly continue on in the position, even after it has been shown that it obviously hasn't come from God.
Who can imagine Jesus, after being shown to be wrong, tightening up the reigns and reproclaiming his "special status", heightening the surveillance of those who are recalling the "old stuff" to inform the "new ones", sending out his apostles as a DF party if someone is found speaking truth about him and his past ?
