Among many things, this has always bothered me about what churches teach, and certainly what JWs teach.
Jehovah is bothered by many things, he looooooves you all, he haaaaates wickedness.
But - God seems (to me) to like to watch it, test people, let all sorts of horrible things happen. How does this demonstrate that he loves humanity? I have just never seen it. Yes, there was a "ransom" (what is that, really, and why is that really needed?) but nothing comes of any of his efforts to put down wickedness. It's always later, tomorrow, next generation, then God will do something. "Wait, let's test more people and see if they will be "loyal" to me." God seems to be saying. How is this okay?
That is why I am now an athiest.
As for the JWs, they read this stuff and think, Jehovah hates slavery! He hates injustice! He hates abuse! Look how he loves us!
How on earth could anyone come to that conclusion?
