He absolutely loves him, and that is one of the things the devil hates about God.
For the moment, I'll assume you have not had an in depth conversation with God, with God giving you explicit statements.
So, my question is how do you know, and what does this term "love" mean to you?
Not saying God is like this, but just digging deeper into the term "love" and what it means or may not mean, I'm thinking of a man that abuses his wife physically, and his wife is angered by it, but the man explains that his wife hates him for the love he provides her--in his actions of correction.
One answer to the question if God loves the devil is:
I don't know.
We like to have right answers for everything question. Then again... "I don't know" can be a right answer if the person saying it truly does not know.
God may well despise the devil. God may be just in honoring God's own grants of privileges and promises. Therefore, God may grant his once greatest angel his wicked desire to tempt man and lead man into eternal damnation. I'm not sure that means God loves Satan the way I love my parents dog or my nephews.
Of course, I could be wrong, I'm not God.
The better inquiry for the young mind is, if you love God, do honor the devil of incredible intellect who hates God and works to destroy God. Before answering that the young mind ought ask if they love their country and national identity more than God Almighty. Because if the young mind is full of hate and revenge against terrorists or treasonous persons in his or her country more than they despise the devil, then chances are they love God a lot less than they love their country and national identity.
