Hi jgnat, I've always asked those questions, every painting the WTBTS portrays shows a nice house in the country side, orchards, lions etc. Right? Okay lets break it down and this is what I asked when I was like 10 years old or thereabouts...
Who milled all that lumber? Who made the large saw blades to run the saws? How is power being generated to run these machines? Did they deliver all that building material by horse? What about all the water needed to keep a large orchard alive? Who's making the pipes to feed the water system?
That's just the basics....
If you believe the bible and God's purpose to fill the earth and subdue it, well, then WTBTS needs to rethink their portrayals. Because that doesn't sound very subduing.
Oh and they say there is enough land so that everyone can have an acre? How are we going to survey the land and keep records? Paper? Who makes the paper? Computers? See where I'm going with this? LOL!
