First off, (these are in no particular order) I would like to make a point about the ransom. Jesus made a prayer to Jehovah saying "Take this cup away from me." The witnesses interpret this as jesus not wanting to blaspheme Jehovah's name. But the more reasonable interpretation is "Do not make me do this." So his great, kind and merciful Father chose to ignore his son's plea and go along with his bloody, and painful execution regardless. What does this say to you? How can people actually believe he loves us more than anything in the world, although he left his scared and loyal son to die a painful death?
I also disagree with the fact that he change the languages of the people who attempted to build the tower of Babel. Now, us being the pathetic, emotionally incapable morons that we are, apparently couldn't do this. So why did he change the languages of the builders? Because they were working together. They were building something that downright proved that the "Almighty" was wrong. Lets put this into another context. Witnesses make this illustration of a boy claiming that what his teacher said was incorrect, so the teacher gave him the chalk to prove him wrong. But, what they forgot to include the part where the boy turned out correct so the teacher snatched the chalk off him scribbled all over the blackboard and said "Ha! Told you so!"
I've got other queries about the beliefs of the witnesses, but I'll save them for a later thread as not to bore you all.
