On one hand they say,"would you drink a glass of water if it had just a tiny bit of poison in it?" yet, on the other hand they will often admit, "even if it's not the truth it is still the best way to live".
In my mind they admit that they in fact will drink a glass with a tiny bit of poison by staying in the cult.
If it's not the 'truth' or completely the truth then it must be false, or, spiritually endangerment, if you will. By admitting that some parts may not be 'truth' then they are admitting that they are teaching and promoting falsehood in re: to God. Wouldn't you think this would be a bigger deal to a true believer? to knowingly be teaching a falsehood about God?
But then I don't think the average jw or watchtower follower (wf, as my friend likes to call them) really cares all that much about God, they care more about what men think and belonging to an exclusive club that hopefully will admit them entrance into their fictional paradise earth if they can just to enough to earn that privilege .
