OK. Let me back-track a little, and tell you a true story. Once upon a time (all good stories start like that) I was an atheist. Without giving the matter much thought, I just assumed that ethics and morality were just stuff people disagreed about. In the same way we might disagree about politics, or aesthetics. Then, I went through a bad time. It seemed my business partner had been lieing to me for some time, and actually had no intention of keeping his commitments to me, and this put me in a bad position financially. I was, to say the least, more than a little stressed by this situation.
Anyway, then I did start to think a little more seriously about ethics and morality. If they were were just stuff people disagreed about, what right had I to feel aggrieved? I had kept all my commitments to him, but why should I expect him to keep his commitments to me? What right had I to judge his deceptions unethical? So I thought, a moral code to live by is 'a good thing'. And, since I had kept my commitments, and he had not kept his, my moral code was the better of the two, because morals and ethics form the basis of the social glue that keeps civilisations intact. But then I thought, if some moral codes are better than others, there must be some moral code that is best of all. And If some moral codes are good, and others better, clearly it is one of the better ones must be best of all.
And then it struck me. This was exactly what all those tiresome Christians had been trying to tell me all along; that God, being perfectly, infinitely good, must be perfectly, infinitely moral and ethical. And to be perfectly, infinitely moral and ethical is as good a definition of objectively moral and ethical as you will find anywhere. And so I began to believe, in God, and God's Will, which, because He loves us, and a moral ife is the best kind of life to live, expresses His desire for how we should live out our lives.
Best wishes, 2RM.
