My honest review of Christianity

[genkaus]

We believe that hell and heaven both have god in them (as you know . . . god is everywhere) The only difference is that those who love God will enjoy being with god and those who hate god won't be able to stand the presence of God and will therefore "gnash their teeth." That will be the greatest punishment possible.
Also we believe that if we pray for the dead, they will be forgiven and if they regret their hatred they will enjoy the same things as the faithful enjoy.

"Greatest punishment possible"? Really? That would show an amazing lack of imagination on your god's part.

First of all, if your god is everywhere - and that includes this world - then it should be clear that people who hate him don't go around "gnashing their teeth" due to his presence.
Secondly, you are forgetting the third option here - people who don't give a shit. To them, your god being present or absent makes even less of a difference.
Thirdly, the statement "if they regret their hatred they will enjoy the same things as the faithful enjoy" betrays narrow-mindedness. "You like having a lot of sex, do you? Well, I hope you get a personality transplant and start liking singing praises of god instead" - that is, effectively, what you are saying. Those people neither need to change their likes nor do they want to - so why would you want them to? Different people like different things, deal with it.
Fourthly, your notion of hell invalidates one of the reasons to believe in it in the first place - the idea of justice in afterlife.

So, to conclude, even if your beliefs about god and afterlife were true, there is still no reason for anyone to change their attitude towards them. I could remain an atheist in life who thinks your god as conceived is immoral, corrupt and a vile piece of shit and go around sinning in whatever ways I want to. Then, when I get to the afterlife, I'd think - "Huh, so god is real. And he is immoral, corrupt and a vile piece of shit" - then I'd merrily go off to hell where I'm sure to find others like me whose company I'd enjoy and be rid of the faithful singing Kumbaya in heaven. And in hell, I'd enjoy myself for the rest of the eternity.
