Gotta give God something simple to fix otherwise He's not up for the task. He seems to be a Jack of all trades and a master of none. Our God is just a mere dabbler. Yeah, that's right. So I said it, but you were all thinking the same thing! Earth was just a part-time hobby that He became bored with right from the start.
Anyway...
I will not ask God to fix the problems that have plagued mankind from the get-go. He doesn't want that responsibility and prefers to let people blame one of His creations. I have a strong feeling He just made up a story about Satan. Probably was jealous that Satan was receiving the worship God thought only He deserved. After all, He is a Jealous God! Our God probably has ADHD or NPD or some other abbreviated issue. Isn't His name an abbreviation too? Come to think of it, our God is a real troublemaker. His behavior is downright trollish. Think about it...but I digress. Back to the question: What would I pray /ask God to fix for me? Something that God could actually do? Nothing.
He can fix absolutely nothing.
