Every religion calls their beliefs "The Truth" otherwise we would all believe the same thing and there would be no differences or wars over it.
But then somebody gets an attitude and MY truth is better than YOUR truth starts....and wham somebody's driving a plane into a skyscraper and yelling "Kill the infidels!!"
So it becomes a happy buzz word that the witnesses in particular love love LOVE to toss around like its a badge of honor and you DONT want to be OUTSIDE that INNER CIRCLE of people who are "in the truth" or the guilt sets in.
"So how long have you been In The Truth?"
"I was born In The Truth and my father is an elder and my mother is a pioneer."
"My family has been In The Truth for three generations!"
"Being In The Truth has saved my life!"
"Isn't it wonderful how we have this Worldwide Brotherhood of friends In The Truth?"
"Oh I didnt find The Truth, The Truth found me!"
I seriously think that there may be a fourth part of the Trinity...this entity called the TRUTH. Its a Quadrinity, truth be known
