You can liken the authority of the governing body with Tommy. Tommy is six years old, playing in a sandbox. He wants to have your shovel, but you don't want to give it to him. Tommy tells you that if you don't give him the shovel, his brother will come by and beat you up. You don't give him your shovel, because you don't believe him. Tommy keeps telling you that his brother is coming over real soon, any minute now. But you still don't give him your shovel. Tommy tells you that he sees his older brother coming right there around the corner... But you still don't believe him and hold on to your shovel. It wasn't his brother coming around the corner, it was someone else.
After a while you find out that Tommy doesn't even have an older brother.

This is a GREAT analogy. They even went so far as to steal the reputation of Bible God and use him as a model for their Watchtower god, complete with all the killing, plagues and judgement. Then they claim that their pretend god chose their organization as appointed muscle on earth.
