In my quest to try to reason with a few people close to me I thought of the perfect illustration as to why we should examine our beliefs against whats printed in the WT or on the JW Website.. Granted, because of the blinders they were on able to accept any part of what I was saying but to any "non-believer" that I have used this with has understood perfectly. So it may be worth a shot to try it out.
If a person were looking to take a trip lets say to a specific resort. If they went to that resorts direct website and ONLY that website then what would they find? Only wonderful things, the best reviews, pictures in the best lighting and the best angles, the best looking meals, the best rooms etc. BUT if a person were to go a website like TRIP ADVISOR, they would see a variety of reviews, some good, some bad, some indifferent but there would be a well rounded perspective provided.
That person booking there vacation could then make and INFORMED decision about where they would like to say. They may come to the conclusion that they still want to stay at this resort because the good outweighs the bad or they may decide against the resort but either way, they were given different perspectives so that a more informed decision could be made as opposed to just going to the resorts direct website.
