"If I were not an atheist, I would believe in a God who would choose to save people on the basis of the totality of their lives and not the pattern of their words. I think he would prefer an honest atheist to a TV preacher whose every word is God, God, God, and whose every deed is foul, foul, foul." -Isaac Asimov
My first doubts as to the legitimacy of Christianity were tied to where salvation supposedly comes from. "For it is by grace you have been saved, through faith—and this not from yourselves, it is the gift of God— not by works, so that no one can boast." Ephesians 2:8-9 I always accepted that, thought it made sense. It was all I had ever known. But one day it occurred to me (and to the best of my recollection I really did think of it on my own, though I now know it's been said many times) that it didn't seem quite fair. From what I'd been taught, someone could be a horrible mass murderer, be guilty of the most heinous of crimes, and yet if, just moments before they died, they genuinely repented and asked Christ into their heart, they would go to Heaven. Yet if someone devoted their whole life to helping others, forgoing any chance at a normal life with a spouse and children, was totally self-sacrificing, and yet did not ask Christ into their heart, they would spend an eternity in Hell. I believe the specific examples I had in mind were Hitler and my little sister, since they were ones I could emotionally relate to. To quote David Mills, author of Atheist Universe, one of my all time favorite books on the subject, it is "a system that admittedly promises heavenly rewards for faith and proper religious beliefs, rather than for real-world ethical treatment of others." I just couldn't see how this was a moral basis for determining who would go to eternal bliss and who to eternal torture. It certainly didn't seem to be the sort of rationale one would expect from a just deity.
I've been told this has to do with the fact that God is perfect, and our sin creates a chasm between us and him that we can never cross on our own. That Jesus's death on the cross was the only way for us to be purified, if we choose to accept it. I'll go into the subject in more detail at a later time, but it seems to me that IF God is omnipotent, as we've been given to believe, there's no such thing as the "only way" anything can be done. If he is all powerful, then the way things supposedly are is the way he chose for them to be. And again, I don't see how this is just.
I've still yet to hear an explanation that seems even remotely morally acceptable to me.This certainly wasn't the only argument that led me to embrace atheism, nor even the most compelling, but it still seems a serious endictment of Christianity, and any other religion that embraces words over deeds.
