Ha!
You know, there is a bible verse where it mentions demons "trembling" in fear of Almighty God. You're right - God is SO POWERFUL and complete, that He puts fear into the terrible!
We don't always contemplate this, even Christians. To us, Christ is just "our buddy" and this "Mercy Mercy Mercy" guy all the time. Almost a "wimp" if we admitted it.
But..............He isn't. He is fierce. He is frightening to those He hates (and yes.....God hates). God has emotions, and He gave us His some of His emotions. One of those is anger. God has Righteous Anger. To get in His Way......is terrible. Frightening. Horrible.
Christ is a God of Mercy. But, when I think about the vermin, the demons, struggling to get out of His way....I have to smile.
