Yes, the light DOES get brighter.....but the bible also tells us that the things of the darkness WILL be revealed and exposed by the light of scrutiny....and we can see that the WTS is no more exempt from these hideous things being revealed than any other religion. You can gently remind your JW family members that all these things MUST take place according to "plan" and according to what they themselves are supposed to believe.
If these "revelations" are important enough to appear on the national evening news, they are not just what some lone crackpot is hollering on a street corner somewhere, but these have the credibility and come from reliable sources or they would not be ON this particular news show.
JWs can only hide from the truth for just so long, and then reality will have to "set in" somewhere in their hearts and minds. I wouldn't count them out just yet, a lot can happen that might very well make them have a change of heart towards the WTS. Don't give up---the fat lady has not sung yet!
