When I was a JW elder and dreamed of living in paradise, I pictured all of the animals, beautiful people, perfect weather, welcoming back the dead and teaching them about God.
The only problem is to get to the point of making the earth a paradise first there will be around 8 billion bodies to bury. Then how are we going to dig through all of the rubble and collapsed buildings using what tools? Who is going to dig the landfill where all of this rubble goes? Maybe we will just dump it into the ocean. I can't imagine that God will start resurrecting millions and millions of people to an earth that is not a paradise yet. I guess that turning the earth into a paradise will fall on the backs of the great crowd that survive the just around the corner great tribulation. I think it may take a 1,000 years of hard work before the earth even looks like a paradise.
I don't think that God will lift a finger to help unless he just waves his magic wand and presto the dead bodies and rubble are vaporized.
I think that the great crowd will make the earth a paradise not God.
