"They publicly declare they know God, but they disown him by their works, because they are detestable and disobedient and not approved for good work of any sort. "(Titus 1:16)
The average person doesn't care what message JW's are preaching at their door as their bad works and lack of good works has made them unapproved to preach any message of salvation. To the credit of most JW's, they attempt to live a moral life according to the rules and dogma of the WT Society, but they fail to listen to their own conscience or to the collective moral conscience of the world. Otherwise, they would have left the KH a long time ago.
The NBC news story on the JW pedophile scandal will make it nearly impossible for a JW to bring any sheep into the KH. It does not matter how great JW's think they are, for if 99% of the public views them in a negative light they will be unable to find anyone to listen to their message. God wouldn't use a gutter religion to spread any message of good news.
What else hurts a JW's image today? How have they been disobedient?
