The JW organisation is one big con trick. They have never got anything right so why should they be right about paradise?
All of the mentions in the Bible of the king bringinging victory over the nation's enemies followed by peace and abundance were heartfelt fantasies which spoke to the underdog tribes of goat herders in Canaan.
The Hebrew speaking exiles could just scrape a living there in the dry highlands in the worst part of the Levant but they had one thing going for them; they were literate. Paradise and freedom from Egyptian rule was their dream. They wrote about independence with ecstatic words of the hope of freedom and material plenty, the two things in shortest supply.
The political paradise never came but the texts remained and gave other people hope in the shape of the upbeat parts of the OT literature. Christianity borrowed the same words for grecianised and romanised Jews who recognised the motif from Isaiah, of freedom, peace and abundance--and the myth was perpetuated, although early on in Christianity, heaven became the fantasy reward for faithful membership.
Paradise as a religious lure is a fraud and pure fantasy.
If it sounds too good to be true then sensible people know it is too good to be true.
