Genesis 1:1 In the beginning God created the heaven and the earth.
He who creates owns. He who is able to keep what He creates is able to give it to whomever He chooses.
John 3:35 The Father loveth the Son, and hath given all things into his hand.
Note that the Father gave all things and not just what he had left after the thief stole what he could. Satan being a creation of God was given over to Christ as well as all that was under his control. Now how can I be sure of that?
Jude 8 Yet Michael the archangel, when contending with the devil he disputed about the body of Moses, durst not bring against him a railing accusation, but said, The Lord rebuke thee.
It was not Michael that won the battle but rather the Lord’s rebuke. A thing possessed cannot deny He who has dominion over him. So all things, good and bad, belong to the Lord.
That is true, but it is also true that we record titles, deeds, and leave possessions in our wills. How can both these things be true? We live in a world that does not recognize God’s authority and as such are required to live by man’s laws. Jesus even went to far as to say; render unto Caesar that which is Caesar’s.
He ended that saying by adding; render unto God what is God’s. Perhaps that is easier to understand if you recognize that God gives stewardship to the unbelievers as well as those who believe in Him.
Romans 13:1 Let every soul be subject unto the higher powers. For there is no power but of God: the powers that be are ordained of God.
Ephesians 6:5,9 Servants, be obedient to them that are your masters according to the flesh, with fear and trembling, in singleness of your heart, as unto Christ; And, ye masters, do the same things unto them, forbearing threatening: knowing that your Master also is in heaven; neither is there respect of persons with him.
