Ok, so you don't necessarily believe that they will go to hell, that's better than what a lot of Christians would say. But still, some people (born in the US) get a better chance at going to heaven than others (born in India), how is this fair and just?
God is the one who defines just and fair. This universe including his home heaven, is his to do with as he wishes. But the bible says...that nobody that recieves a child of god, because they are a child of god, will loose their reward. And that means ANYBODY. The reward is not heaven. A son of gods' reward is not heaven, god is their reward. Heaven is their home, not their reward. To get to know god is a huge reward.
I believe in reincarnation, and therefore i can be sure that whoever was chosen to conform into the image of his son, will have the opportunity to do so. Even though christianity is a Major religion on this earth, only a small remnant of them will be the sons of god. It is also the 'religion' into which the bride will be born. But as in any kingdom there are citizens of the country, sons of the king, daughters of the king, and the bride of the Son of god and weddingguests.
Also...nobody is going to hell. We are all in it already. The idea is to get out of it. A king has the right to weed out of his kingdom the people who would disrupt the peace. Violent people, i.e. the sons of the devil will not be in heaven or the new earth.
