Earth surely does come with a slice of heaven from time to time, and it also comes with slices of hell too. The biblical hell is a sea of fire where we, as well as satin, will burn until the end of time, which brings me to a question: Some people like burning and torchering themselves, so would hell be their heaven and would heaven be their hell?
I think this boils down to the individual and their version of reality.
Sure enough, the bible clearly states that all sinners in hell are unhappy, but I am pretty sure that it also states how torture is unpleasurable. How so? In our world many people like torture.
Look on the internet, people are crazy!
I do agree with you though, earth can be very lovely and very wicked.
