Why do,you think no other bibllical religions teach this promise? Even the JW's didn't before their doctrine change in the 30's and the adjustments made to the NWT after that desicion.
is it in your bible? Name the scriptures that promise it..... Then go read it , then read it in context, then look at the original translation ....the word isn't earth its land. Then look at the second scripture the WT use.... The word paradise was added by WT, what was the original verse? ...I tell you today you will be with me in the kingdom of heaven.
Before you have a go at me for being bias, I am a atheist, I think the bible is nonsense, but it was only after this basic research i came to the conclusion, but my point is.... The verses are changed, the original verses are as untrue to me as the adapted. But research where the idea comes from and when they introduced it and why.... They claim everyone was asking for another hope because they didnt want to go to heaven, if you believe that, ok. But can you imagine that really? In reality they had taught that the reason the religion was only small was because only 144,000 would be saved. Then when the numbers gre, they had to,explain it away. They did it with one verse from psalms about jews inheriting the land, ....the meek will inherit the earth. Ta da.
In the whole bible...... That's the only verse they have..... That make sense to you?
all those books 'you can live forever on a paradise earth' and 'knowledge that leads to everlasting llife'.
They don't quote verses, they use pseudo logic about humans not wanting to die, wanting to stay on earth.... And that's all they have.
