Ooh, I'm excited to answer this one.
Firstly, all peeps who belive in Jesus get to live with hom on the new earth for the rest of eternity. How will that work out? Well listen,
Before Jesus walked on earth, the people who died all went to a place called Hades. There was a good place, called Paradise, that was separated from the bad side, Hell. When Jesus died, he went to Paradise and took all of the people there to Heaven. Now, whenever people die, they go there.
One day, hopefully soon, all of the believers will be raptured up to a tabernacle in the sky. We will then wait seven years, years in which the world and its unbelievers will go through trials and tribulations.
After the seven years, when the earth is quiet and empty, the believers and Jesus will come down to earth and live for 1000 years. We will then move to a new earth and a new heaven, to live for ever and ever.
This is cool, because on the new earth we will be given new jobs, I have no idea what they could be. But I think in my free time in this new world, I would be able to invent a fully immersable virtual reality minecraft game.
. . .
When I say it like this, it is hard to believe, but I do.
You can also ask for a sign. I know it might be weird to pray to someone who you think doesn't exist, but try.
Choosing to believe in Christ or not to believe, that is the question. And it will be the most important decision of your life and death.
Cheers!
