Why do JW's elders act like their failed predictions is no big deal?
well it's not the failed predictions of the elders but of the GB. The GB tells the elders that it is no big deal, so that is what they tell you again.
very "interesting" reasoning about the false prophets and the law, this elder had. Most JW's do not call the organisation a real prophet, although they say it is gods channel etc (all things that a prophet shoud have, they say they have). That is why they need such strange excuses
