The above paragraph--that the planet will never be destroyed or depopulated--is a lie. Now, it will not happen directly because of God (He needs us to entertain Himself and so He can have something to watch suffering while He eternally promises deliverance; destroying all mankind would defeat that purpose). However, the sun has its life cycle. Once the sun runs out of gas, it will expand. The inner planets will be swallowed up (some scientists expect it to reach Jupiter). For sure, if the earth isn't swallowed up, it will be incinerated and become too hot for life to survive. At which point, the planet will be depopulated.
And, even if we survive this, once the sun goes out, it will become a white dwarf. If the earth is still around, it will now freeze. We will have an ice age like nothing we have ever experienced, and all the "global warming" in the universe is not going to do it any good. Sunlight will be missing. The sun will appear as a tiny point at this point, giving us nothing but night. There will be nothing to eat, and no sources of energy. It is only a matter of time before all energy will run out, and any humans alive at that point will suffer the greatest energy crisis imaginable. Eventually, anyone that survives the inferno will freeze to death.
And Jehovah ain't gonna lift a finger to stop it.
