The trouble with grobblewobble's "exhaustive" case analysis is that it completely hinges on heaven or hell, or God's intentions, being a certain way - basically it limits itself to possibilities A and B where there are many, many more, and is thus anything but exhaustive. Thats what makes it wobbly. But who am I to continue to grobble about such things?
(I am a bad person.)
Because Jesus is human (mostly). The only alternative would be to father multiple Jesuses. As far as I'm aware, being a heathen - i. e. not aware of the teachings of Christianity - counts as a mitigating circumstance, and if you still did good you would still get to go to heaven (and of course there are other, more restrictive views out there, I wouldn't want to believe those either). And this is also why missionaries were sent out into the world; to grant more and more people access to these teachings.If God is omnipotent, one would think that the fair thing to do would be sending messengers everywhere to give everyone a fair chance. Even today, people born in many parts of the world don't have access to the Christian doctrine at all, while other people do, that seems quite unfair.
