The one that my mum would say is "a good relationship with God and the promise of everlasting life".
I don't think growing up JW necessarily means a good relationship with Jehovah if he in fact exists.
Growing up JW fosters following rules due to guilt trips and not logical reasoning. Rules set by men you will never meet and to whom you mean nothing. Rules that are no where to be found in the book of instructions supposedly left to us by God. Rules that will see you struggling to survive in the real world and leave you ignorant of the state of the world and how you could contribute to making it better.
Growing up JW makes you arrogant and intolerant and without compassion for fellow man and most of all judgmental about absolutely everyone.
Not at all what Jesus was, in whose steps we are meant to follow, if he did in fact exist.
