God is sovereign. He is the absolute, unquestionable ruler of everything.

There are a myriad of spiritual entities with differing roles and levels  of power that he has created. He rules them all. Every intelligent  entity that God created, whether they are Spirit beings or human beings, they have been given free will. They may choose to rebel against the will and word of the most high God, but they will face His correction as a result of their disobedience!

Romans 1:20 For the invisible things of him from the creation of the world are clearly seen, being understood by the things that are made, even his eternal power and Godhead; so that they are without excuse:

Isaiah 57:15   For thus saith the high and lofty One that inhabiteth eternity, whose name is Holy; I dwell in the high and holy place, with him also that is of a contrite and humble spirit, to revive the spirit of the humble, and to revive the heart of the contrite ones.

Daniel 4:35  And all the inhabitants of the earth are reputed as nothing: and he doeth according to his will in the army of heaven, and among the inhabitants of the earth: and none can stay his hand, or say unto him, What doest thou?

Daniel 4:17  This matter is by the decree of the watchers, and the demand by the word of the holy ones: to the intent that the living may know that the most High ruleth in the kingdom of men, and giveth it to whomsoever he will, and setteth up over it the basest of men.
