Thanks, Leoalia. The first time my honey explained the Paradise population thing, I tried to explain he was all backwards. He kept saying Heaven is too "small" for Christians, whereas the Earth is "big". Then he described how the loved ones who have passed on will get that second chance. I started to do the math, and I told him there is NO WAY the earth could support such a population - it would be crowded!
Unfortunately, my man is not so good in math. He couln't see it.
You have laid out the problem very nicely Leoalia.
Also, am I right that JW's believe that people will still marry, have children, etc. etc. on Paradise earth? Nobody dies? No children die? Fertile for eternity? Unsustainable! I have read enough SF to know what happens next. Colony ships! The JW's better start courting some rocket scientists. Heaven knows they are short of brainiacs.
