So your argument is entirely based upon your own subjective experience, is it not?
I will grant that I cannot know God would not change the moral order on philosophical grounds. I admit it is an object of faith to hold this. It is not, however, entirely subjective. Faith is rooted in reason, reason is rooted in faith. I am saying that there are reasonable grounds for having faith in a God who would not alter morality arbitrarily.
Furthermore, my indictment of morality as a product of evolution as being inevitably arbitrary still stands. Is it not simply a matter of time before such a morality changes?
