As Vidiot said it, Obey. Obey the orders. Wether you believe in 1914 or not, it does not matter. The doctrines are many and diversified with multiple faceted opinions. This assures that you have at least something you believe to be a unique truth, such that would keep you attached to the religion and ready to obey direction. Obedience to the GB is the ultimate goal, regardless of the foundation. Wether you obey because you believe in1914 but not in the overlapping generation or obedience because you don't believe in 1914 but think no other religion follow the mandate to preach. As long as you have a reason to be attached, you will obey. See that latest leaked letter. What was one of the questions the elders needed to answer? Was it not wether the candidate was "humble and readily follows counsel"?
