Yeah I am new here..
Anyway I've had this same question going over in my head for a while now. and have had conversations about this very subject with borothers..
Its interesting to say the least.
My conclusion is that God has not told or comunicated to the FDS any information. and thay have just been spinning crap for the last 100 or so years.
Logic to me says if a perfect god was telling humans his will, so save all mankind form death and destruction he would not be spinning the crap the WT seem to come out with.
Then change it a few decades later. Because God cant lie apparently. so why feed his peolpe false infomation. It does not make sence to me.
Oh and dont try the he is sifting his peolpe and weeding out the slackers and the like..
In my book he will do that at the so called armageddon when he kills all the bad people. so why sift and clean out his people during these last days.
It's all crap. the whole JW thing is just another American chirstian adventest type modern religion.
I for one am over it.
Still fading though..hahahahah
