On the question about His will be done on the earth.
All comes from God.
He made, and is higher than, all.
Satan is not higher than Jesus Christ.
Satan is the god of _this_ world.
"_this_ world" is not speaking of the earth, but Satan's system that is upon it, the same as bread was not speaking of dough, but Gods kingdom within us.
Gods will comes in light. God is perfect, and His kingdom is within you. His name is holy.
But for Satan,…
The wicked aren't even willed to anything unless God rains on them lol.
They'd be pagans out in the wilderness, carving idols and making strife with trees, if they weren't rained on.
The demons have to hope that the unclean are rained on by God, for in the day of the wicked this is how they even have a house to begin their evil deeds. The unclean house demons within their body.
Compare this to the Lord, who can walk on water the same as not knowing you're naked (like a video game maker using noclip on a map editor :D ), who can just say to the sea "give me a path," and it be granted to Him, parted. He can do all. His very will was to make the earth, and all above and below it.
And He willed that <3
And his spirit, went across it.
Satan being the god of this world is greatly nothing like Jesus Christ being Lord. It's just to say that something was given to Satan.
To help you understand, when all of the earth was flooded, the earth was still here, but _this_ world was not, because that which Satan pries on was nowhere.
