I remember and elder giving a talk and he mention how he never was exsposed to sin, because he was born and raised in the "Truth". He said that he asked a brother that was not raised in the "Truth" what was it like to live in sin. Anyway he went on to say that worldly people who come to know the "Truth" or more thankful for it than ones whom were raised in it.
I think the ones that was raised in the "Truth" had more time to realize that it is a bunch of crap.
