That's an utter cop-out.
If God is not subject to the moral laws that he himself defined, then they are not laws.
This is not a dodge. As one who's faithful and truthful, we must expect God to be consistent and not arbitrary -- IOW, unchanging. No, he does not play tricks on men. to "play tricks" is to assume that men enjoy sovereignty in their own right, without respect to God, and that man has some sort of right to be unmolested by God. I know this is probably the vierw you favor. But once again -- if that's what God is -- one who holds less than absolute sovereignty -- who needs him? OTOH, if God is an absolute sovereign, with ALL the rights, who nevertheless wishes man over time to acquire an intimate knowledge and relationship with him, who are we to question the means by which he chooses to make himself known?
Please consider that your model of a legalistic, moralizing god may be primitive and inadequate. All the easier to shoot down, no doubt, if that is your purpose, but unworthy of you.
