Exodus 20:5

thou shalt not bow down thyself to them, nor serve them: for I the Lord thy God am a jealous God

So God himself admitted he is a jealous God.

This seem like creator and creature have conflicting traits.
One is Jealous and another is excedeengly Proud.

How do we reconcile two spirits with these seemingly antagonic characteristics?

Now, when Lucifer is refered as "that old serpent" more than one time, it feels like God really felt betrayed when Adam and Eve fell.

Now, when Elijah came, he gave the whole thing (the last 10 thousand years nonetheless) a pedagogic character. As if the whole point was to teach a lesson, and enlighten Lucifer and his followers.
