I have never really understood how God can be jelous.Like in the Bible theres times when he says dont worship other gods because I am a jelous God.Jeaous of what?.I mean he knows that when people did that they were worshipping powerless idols and I know that,that can be like a metaphorical way of saying that if your devoted to other things you’ll be more distant from me but what’s with the word jealous being used?.The closest thing to an explaination for a jealous God that I have found is in a part in “Les Miserables” when Cosette reads one of Marius’s love letters.Can anyone please expalin this concept to me?.
Envy is sorrow that someone else has a good thing. Jealousy is sorrow that you don’t have it yourself.
To be rightly ordered towards your own good is (obviously) good for you. God loves you and desires your good; therefore God wants you to be rightly ordered toward your own good.
God is the ultimate good of the universe, the one thing towards which the whole universe is ordered, and the one thing that the whole universe desires and seeks and finds its fulfillment in, especially rational creatures like men and angels. And he knows he is. Therefore he wants you to be rightly ordered towards him.
Part of being rightly ordered towards him involves worshiping him. Therefore God wants you to worship him, not because he is full of himself, but because he knows it is good for you to do so.
When you give worship to a false god or to a mere creature, you are subverting your own good and ordering yourself towards something that may be kinda good, but not your real, ultimate good. Therefore God, since he loves you, is sorrowful that you are subverting your own good.
Since God is your ultimate good, and you are ordering yourself towards something else and giving a false god or a creature the good of worship, God is sorrowful that you are giving the good of worship to something that is not him.
But sorrow that someone else has a good thing that you wish you had, is jealousy.
Therefore God is jealous, and rightly so.
