@Setanta,
I admit to confirmation bias based on my belief that the Bible is consistent. But I'm no genius. And I'm not an official representative of the Watchtower Society. One of my main reasons for posting here is to sharpen my understanding. You have made points, as have Blue, Ros, and a few others. In fact, I find non believers to be more efficient as sharpening stones.
However, no one here has yet caused me to lose sleep over my profession of faith.
If there is a God who created in us the traits of love, justice, and wisdom, and put us on this amazingly beautiful earth, then certainly He would explain to us why we have had 1000s of years of human misery and what He intends to do about it.
The Bible presents the best explanation I have yet to find.
