Moral Choices Make a Difference

I'm puzzled by the contention of doctor craig that, on his view, moral choices are significant and make a difference. In i view, they're not. And indeed, it ultimately will be in your prudential interest to obey god in the long run. So i think that theism offers both a prudential value as well as moral value. Whereas on atheism, ther there simply is no, no ultimate significanced and final value to acting morally.
