You're all just taking it for granted that god is somehow revealing himself to every single life on the planet, and anyone who isn't a Christian has rejected god and deserves their eternal suffering. This assumption takes incredible faith, but demonstrates an intense ignorance of anyone else's perspective but your own... You're assuming that Christianity is a conclusion which is so obviously true that anyone who hears of it should convert, you don't think it's possible to just not believe, you have to call people stubborn or say they're rejecting god. Newsflash, they don't think that the god they're rejecting is real. So if it is all true, all the people in hell would have not known that god existed at all. Not only that, but you think that even if someone hasn't heard of Christianity, they should somehow repent for their sins and believe in Jesus because of observing nature and feeling guilt for wrongdoing? This is ludicrous, and the ONLY foundation to believe any of this is found in scripture...
If you want my opinion, people made up this whole "people choose to go to hell" idea because they felt so guilty about the existence of hell in the first place.
