Man or Rabbit

Can someone lead a good life without being a Christian? While I will not be stating the full extent of my real opinion on this matter I think that Lewis answered this best. “But the man who asks me, 'Can't I lead a good life without believing in Christianity?' is clearly not in the same position. If he hadn't heard of Christianity he would not be asking this question. If, having heard of it, and having seriously considered it, he had decided that it was untrue, and then once more he would not be asking the question. The man who asks this question has heard of Christianity and is by no means certain that it may not be true. He is really asking, 'Need I bother about it? Mayn't I just evade the issue, just let sleeping dogs lie, and get on with being "good"?” Lewis states here that this is not the question that these men are asking and what they want to know is if they really have to go out of their way for this whole God thing. The answer as Lewis quite plainly puts it is yes, yes you do. While he points out there is what he would call good people who had never heard of Christianity he would state that the key difference between them and the people asking the main question here is that these people have heard of it and just like every other human out there want to know how lazy they can be. So basically according to Lewis if you have heard of Christianity it is a prerequisite for leading a good life.
