This sounds like Karlund's comment to my post "On Atheism and Morality". But, unlike Karlund, when Dawkins poses the question he sets out to expose the 'positively ignoble' outlook of the religious. He says:
my immediate temptation is to issue the challenge: 'Do you really mean to tell me the only reason you try to be good is to gain God's approval [...] to avoid his disapproval and punishment? That's not morality, that's just sucking upBut is this really how religious people reason? Do religious people actually seek God's approval?
