That's great. If you see someone flirting with your mate or worse yet, catch him or her cheating on you, would you not feel violated and harbor feelings of jealousy?
This is the same kind of jealousy God is speaking of my friend.
I can accept your definition of Godly 'jealousy' herein above, however, if that is true, it would seem to undermine God's supposedly perfect, infallible nature.
Jealousy is a 'human' emotion stemming from fear and possessiveness. In the examples above, jealousy resulting from a simple flirtation would be derived from fear that one's mate would actually respond in kind to the flirtatious overtures. In the 'flirtation' example, the jealousy is a product of human fear--fear that one's mate would be unfaithful if given the chance.
As for jealousy resulting from an actual consummated affair, where one's mate does in fact 'cheat' on them, that is jealousy derived from possessiveness. We don't own our mates. And while we have certain expectations based on both spoken and unspoken agreements, such as the expectation of faithfulness in a monogamous relationship, our jealousy is born of possessiveness, a feeling that our mate is bound to us in a way that allows us certain control over them. Of course, that jealous feeling is also exacerbated when combined with the inevitable emotional hurt and loss of trust that comes with such a betrayal. But still, all these reactions to events you have mentioned are the products of a fallible human bio-emotional system at work.
Are you saying that God has human emotions that can be provoked, strained, weakened and exacerbated by our thoughtless flirtations and dalliances with people other than God? Does God fear our flirtations with other deities? If he is omniscient, doesn't he know there are NO other deities? As far as that goes, if God is omniscient, doesn't he know the true intent of our hearts and minds to begin with, thereby making his feelings of fear and possessiveness over his relationship with us a bit meaningless?
