Some here have wondered why with overwhelming evidence, many JWs can't see the forest for the trees, whether it be the UN issue or the child abuse issue,
Here is a quote from this week's book study material:
In our day some might wonder why Jehovah through Isaiah and his fellow prophets, spent so much time condemning the folly of idolatry. The uselessness of man-made idols may seem obvious to many today. However, once a false system of belief has been established and widely accepted, it is hard to root it out of the minds of those who believe it. Many contemporary beliefs are as senseless as the belief that lifeless images are really gods. Yet, people cling to such beliefs despite persuasive arguments against them. It is only by hearing the truth again and again that some are moved to see the wisdom of trusting in Jehovah.
While the WTS has a different application, it fits the situation here when trying to convince JWs that the child abuse issue is real and in their backyard. "It is only by hearing the truth again and again that some are moved to see the wisdom. . ."
