The problem lies with The Bible, it is inconsistent and contradictory in many aspects of it's stances. It is also many times over morally illogical in many of these stances, there is no real way to reconcile it without sending some innocent to the fiery pit. To get around this, many blanket the Bible with there own morality and try to twist what it says so they don't have to think or say "you are going to hell"
Which I think was demonstrated in the thread I made entitled "Am I going to Hell?". Some laid out their beliefs and what is stated within the dogma and would not comment any further, preferring that I draw my own conclusions. Which you know what, I didn't really mind it was merely people being nice and trying not to offend.
Here are your choices in the matter of Heaven and Hell
1. "Only those whom accept Jesus as their savoir are saved"; this is a malevolent God.
Billions burn for mere ignorance and not having the ability to not be ignorant. This is what the Bible says it is morally unjust and therefore would be the workings of an unjust God, which is against what the Bible says.
2. "Those who are good get into heaven anyway"; this is the fair God.
Makes Christianity obsolete and redundant, not only does it invalidate the Bible but there is no reason to go to church, pray or spread the word. Just be a good moral person. You could argue that spreading the word of God will make more better people, I would disagree. Spreading the word that being a good person will get you into heaven would be the adequate route. Not using the Bible at all would be preferred, as it (as mentioned above and the reason this thread exists) is a riddle with non-sense and contradictions.
3. "Those who are expose to Christianity must get into heaven through big JC, those who don't get into heaven on good behavior."; this is the jerk God.
Those who have the misfortune of being exposed to Christianity have to spend many hours thanking and praising God. These many hours could be spent doing something useful, like washing their car or jerking off. Chances are these Christians are already good people and do good things, btw most of us are. Now all of a sudden they have to go to Church every Sunday (sometimes Wednesdays too!!), praise and thank God for any measly thing that drops by in that persons favor.
All the while the good person without knowing Christianity gets in on being themselves. Now being a Christian does have it's pros'; for instance if you do something bad you can be forgiven and all those hour of praying will probably tip the scales too. Now the non-Christian is in a slightly worse sin-ario (see what I did there?), as it stands there was no one for the non-Christian to ask forgiveness from (well unless you count the one they committed the crime against. YAY for vicarious redemption! You don't have to face the one you wronged!). So logically the pros and cons of the non-Christians life will be weighed, unless there is some of that God knows your heart stuff in there.
So one way the Christian is at the disadvantage the other they have the advantage, either way it is unfair.
4. "God/gods do not exist and neither does an afterlife"; well you get the idea.
