The past does not exist anymore--its 2017--live in it--The JW teachers made correction to their errors,
Let's see, is 5 years too far in the past for you? For 100 years they taught they were appointed over ALL your gods belongings, up until 2012. In 2013 they finally decided they weren't, and they won't be until Jesus comes again.
I wouldn't want to serve a god that let his people be taught a lie, error, misunderstanding, or whatever YOU want to candy coat it with for 100's of years before he would correct it. I can hear it now, your god says, "that's not what I meant, oh well, they can believe that for a few hundred years and I'll set them straight".
Your 'slave' is no different that the 11 Apostles that walked this earth, please point me to one teaching they taught that they had to come back and say, "that was wrong, we erred, it should be this", just one!
I bet if the past of your cult was all true, the past would mean something today, wouldn't it! But since it was all garbage, it doesn't matter because it is the past. How many people you think lost their families, friends even lives because they didn't believe the trash that was taught? Do you even consider that? What about the blood issue, your god commanded not to take in blood. How many people died because they wanted to 'serve' your god. Then your god changed his mind and said, "blood fractions are ok i guess, let them make the decision". How many people, including kids did your god let die before he changed his mind?
