Religion, Morality, and Kitty Wells

Country music, as most of us know, is  the most theology-laden form of popular music. The lyrics of this song, sung by Kitty Wells in the early 60s, illustrates, I believe, something interesting about the effect of religion on morality. It is a song of a woman who supposes herself to have been a wrongly deserted wife whose husband has given her divorce papers, all legal and proper. However, she asks whether "God is satisfied" with his actions, telling him that he will be called to account for what he has done by God, and implies that his lawyer won't do him any good when he stands before God and must be held accountable for his actions.

Your lawyer called and said he had the papers all prepared
To sign my name was all I had to do
He saw the judge, now he seen me, there's only one thing left
Will your lawyer talk to God for you?
Will your lawyer talk to God and plead your case up on high
And defend the way you broke my heart in two?
Manmade laws to set you free on earth but is God satisfied
Will your lawyer talk to God for you?
We all face that final judgment and it's very strict they say
When your time comes, I wonder what you'll do
Will you bow your head in shame or will you turn your head away
Or will your lawyer talk to God for you?
Will your lawyer talk to God and plead your case up on high
And defend the way you broke my heart in two?
Manmade laws to set you free on earth but is God satisfied
Will your lawyer talk to God for you?

I am not saying anything about the morality of divorce in general. Clearly, it is evident that at least some people desert marriages without adequate moral justification, and the law, as we currently conceive it, cannot prevent them from doing so. I bring these lyrics up because it seems to make nonsense of the popular idea that somehow religious belief, or lack of same, isn't a game-changer when it comes to morality. Assuming atheism, this appeal would be plain nonsense. Again, I am not arguing that no one can follow a moral code without a belief in God. But I think we must admit the force of this sort of consideration, and face that fact that many people, over the centuries, have turned away from a wrongful act because they believed that God would hold them accountable if they performed that action. I am thinking primarily here of the accountability and shame for these actions, as opposed, say punishment in hell. If someone can't see the moral force of this sort of thing, then I would have to say there is a screw loose somewhere.
