okay, bob. here's how i see it.
God created the world. how he did this, i dunno, could be big bang, could be quantum, whatever, the methods aren't the important bits. why do i think God created the world? cos the probability of a universe randomly coming into existence is just amazingly amazingly infinitesimally small. it's easier to belive it was created.
if God created the world, he also created us. therefore he owns us, or at least rules over us- like a potter and his pot.
if God rules over us, and we disobey him and reject him, then we are in the wrong. and we do disobey and reject him. all those people who say people have a 'spark of goodness' or are 'inherently good' are deluded- just look at our society, what we do to our fellow human beings.
if we are in the wrong, we deserve to be punished. which we are. through death, and suffering, and separation from God. (who gave us life, don't forget). And when i say death i mean forever.
JC, who was God, came down to earth as a man, died in our place, was raised to life (as documented by the gospels).
so what? we can either have faith that JC did so, or we can continue as we are.
edit: oh yeah, i forgot the most important bit. since JC died for us and was raised again, that means we don't have to die the eternal death, we can live after our physical death. that's what having faith in JC will do for us.
