Something that opened my eyes as I was re-examining "the truth" was the verse at James 1:27. In the New World Translation the greek word in this verse, threskeia, is translated worship, which is fine except that it hides a more important meaning. This same word can be, and most often is translated religion.
For Witnesses, the matter of being the "one true religion" is all important. You are taught that it is vital for survival to identify the true religion and attach yourself to it. But this concept of there being an organized institution that has been selected by God is, under the Christian system, fundamentally flawed. For we need not look externally, but internally.
We see from James' statement below (from a variety of translations) that true religion is not institutional, it's personal. For the activities James mentions come from our own heart-felt desire to do good for others and to live according to bible principles -- scripturally, that is the "true religion".
I have, with some success, been able to share this point with others to help them see beyond the concepts that so many of us have been indoctrinated with; perhaps it will help someone you know.
