None of my business of course, but I'm convinced that belief in it is the fundamental requirement for Christianity to be morally sound. I just can't reconcile any other view with my idea of good and evil. Even the free will argument doesn't really make any sense to me.
Why should God force salvation on someone who knowingly rejects it?
2. after death, either some people don't love God so God's light seems to "burn" them while the same light brings bliss to others...
This is essentially the Eastern Orthodox belief regarding the nature of Hell. In essence, the only difference between Hell and purgatory is that one is permanent and the other temporary.
A couple of issues: First, the only way this can even work is if we assume temporal causality and the nature of human choice extends outside our plane of existence, as it were. I'm not sure that's really consistent with traditional Christian thought; generally, our decisions are thought to more or less "set" into place at the time of death.
Second, God torturing people into submitting to and "loving" Him might be even worse and more malevolent than eternal separation/other theories of Hell; also, this seems to contradict so many other points regarding free will and the point of Jesus and faith that I'm not even sure where to begin. If God will just torture everyone or overpower them into loving Him in the end, what's the point in everything else He's done? What's the point in free will? What's the point in belief? What's the point in Jesus's death? Can such a God really be called just? Such an outcome seems to strip away any sense of responsibility for one's actions... I just can't see it.
