Good points LW.
Just to be clear i'm not saying that I do believe this at all. I'm just saying that this argument to explain the bible is much more rational than arguments presented by non JW Christians. I have thought of the fallacies like more people being born and God expecting us to preach to them, it's one of the reason I'm leaving.
Having given these sorts of things a great deal of thought, I have concluded that I cannot say for a certainty that there isn't a designer (agnostic position mostly). But I have seen enough evidence to cause me to conclude, that all religious holy books are garbage when really analysed. And that if a designer does exist, he obviously doesn't care what goes on here; so why should anyone care what it thinks, and waste our time following the fantasies of long dead lunatics? Rather, it's high time for everyone to be freed of the bondages of religion, and live a purposeful life that is not in fear of a celestial dictator, who has not even proven he is really there or that he cares.
If we don't have rationality and logic then we have nothing.
