I find the OP to be a particularly interesting question given that God supposedly designed and created jealousy. Now a human feels jealousy as a spontaneous, involuntary response to stimuli, however for God jealousy cannot be spontaneous (by omniscience he knows eons ahead of time that such a feeling will occur) or involuntary (by sovereignty). This means that he must be willingly choosing to be jealous much in the same way that we might choose to wear a particular hat or shoes.
I know I keep going back to this sort of point about God being the author of everything, but I think it is fundamental to understand. If God is the creator of all, then any justification that xtians use in any circumstance for their deity is, by their own doctrine, a rule or a condition authored by God. Therefore it cannot be used to justify any action or sentiment of God because the very condition or rule that justifies God's choice was itself a choice of God. It's an idea I like to call "God in a box" because so many xtians commit this fallacy. So often they declare god to be the creator of the world including all emotions and ideas and everything else, and then they use that creation to constrain god's design of the creation in the first place. Darfius was especially prone to this sort of error.
Now let us consider dj2's "god jealousy" (I suppose this is an element of the same set as dj2's other brilliant insight, "god time."😉. Clearly, he has failed to establish what such a thing is, that it exists, or even why it should be properly called "jealousy" in any sense, however, if we humor him, then we have to ask, "Did God create this 'god jealousy'?" If so, than the "God in a box" argument above still applies. If not, then where did this larger god reality come from? Did it come from nothing? There must be a designer of this spiritual world, a bigger creator that created 'god time' and 'god jealousy.' So if we accept dj2's claims, then once again I offer the following 'truth':
The natural is evidence of the supernatural. The supernatural is evidence of the super-spiritual. Praise Muffy!
