God's feeling of failure.

[Wyrd of Gawd]

You take the good with the bad. We all do it.

"For the joy set before Him (Jesus), He endured the cross...."
That joy is every person who chooses to be His eternal companion- His family.

Lucifer hates you so intently because you are intended to be his replacement, since he disqualified himself from his high position. Even though he was covered in jewels and was the Music Minister in Heaven, he CHOSE rebellion.
We, who have not seen and dwelt in glory unsurpassed (like Satan), yet believed and chose God's Redemption are destined to a higher place than him.

No God is not depressed.
He is the most joyful, delightful being in the universe who is awaiting the fruit of wisdom.

Whether you know it or not you just the described the king of Tyre as the Lucifer character.
