You present a good question and the logic offered is it doesn't mean what it says or that was intended just for the Jews. In other words cherry picking again. God of Abraham doesn't practice what he preaches because he is no god to begin with.
He is just like all the other gods who came before him. There is no need for a real god to be jealous, nor would a real god be concerned with competition. After all the god that could do anything would leave no doubt as to who was god if that was the intent.
Also it implies need. The god that makes all would have no needs it can make whatever it wants be it action or material.
Hahahahaha, Funny statement There is only one God, thats it jealous is not very accurate word, (this is due to translation) the more accurate word is zealous God is very zealous for his people, and it dissapooints him very much when people worship false gods, becuase He is the only LIVING GOD and every other god is a false and dead god created by humans, GOD was not created by humans, HE CREATED HUMANS, Hope this helps.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
