Both, but at different times. Okay. So... you think that when Jesus comes back, Israel will become the kingdom on Earth but meanwhile there’s a kingdom in Heaven too? Like, Israel for the ones who are still alive, and Heaven for the ones who are already dead?
There will be an Earthly kingdom for 1000 years, then the final battle when Satan is released, then the entire physical universe flashes out in a moment with a “great noise.”
