God is sovereign over Satan and his angels and the world forces of this present darkness.  
(Ephesians 6:12)  Satan is a created being who attempted to overthrow God.  Satan makes his
statements of self-will in Isaiah 14:13-14,  "You said in your heart, "I will ascend into heaven; I will
exalt my throne above the stars of God! I will sit on the mount of the congregation in the far north.  I
will ascend above the heights of the clouds.  I will make myself like the most High."  God's answer to
Satan is in verse 15 of the same chapter,  "Yet you will be brought down to Sheol, to the depths of
the pit."  Satan has no power to do anything contrary to the will of God.  "Now the salvation,  the
power, and the kingdom of our God and the authority of His Christ has come, for the accuser of our
brethren has been thrown down, who accuses them before our God day and night."  Revelations
12:10  Satan is no longer a problem in heaven, instead he is here to spend his wrath on earth.  
"Therefore, rejoice heavens and you who dwell in them. Woe to the earth and to the sea; because
the devil has gone down to you, having great wrath, knowing that he has but a short time."  
Revelations 12:12  Satan can spend his wrath only in accordance with God's will and purposes.  
Besides being 'the Accuser of the brethren,' Satan is the destroyer (Isaiah 33) as well as being the
adversary of mankind (1 Peter 5:8).

We can see this relationship in the book of Job.  In Job 11:1 Satan says to God, "But put forth thy
hand now and touch all that he has, he will renounce You to Your face."  Satan is asking for God's
permission to test Job.  In verse twelve, God gives His permission,  "Behold, all that he has is in your
power, only on him do not put forth your hand."  So, it is God's will that Satan can test Job.  Satan is
"a dog on a leash" and can do nothing against God's will.  God in His sovereignty, transforms Satan's
evil and rebellious self-will into the fulfillment of His own will.  As it says in Psalm 119:9,  "They
continue this day according to Thine ordinances, for all are thy servants."  "For by Him all things
were created, in the heavens and on the earth, visible and invisible, whether thrones or dominions or
principalities or powers - all things have been created through Him and for Him."  I am not saying that
Satan desires to serve the will of God; yet he cannot operate outside the will of God or contrary to it.  
"There is no wisdom nor understanding  nor counsel against the Lord."  Psalm 21:30

So, everything in existence is according to the sovereign will of God; both good and evil.  "I form the
light and create darkness; I make peace and create calamity; I am the Lord who does all these
things."  Isaiah 45:7  "Who is He who speaks and it comes to pass, does not the Lord  command it?  
Does not evil and good come out of the mouth of the Most High?"  Lamentations 4:37-38  "Only One
is the  Lawgiver, He who is able to save and to destroy."  James 4:12  Jesus says this same thing in
Matthew 10:28,  "Do not be afraid of those who kill the body, but are not able to kill the soul; rather
fear Him who is able to destroy both soul and body in hell."

The choices of human freedom, as God has ordained them, were originally put forth in Genesis
4:6-7.  In these verses, God is talking to Cain who is angry at God for rejecting his offering.  "Then
the Lord said to Cain,  "Why are you angry? And why has the expression of your face fallen? If you
do well, will it not  be lifted up? If you do not do well, sin crouches at the door and it's desire is for
you, but you are to rule over it."  This is the way it is for each human being as they have the moral
freedom to choose between God's will and evil; a choice that Satan no longer has.

As the mystery of lawlessness is worked out in accordance with God's will (2 Thessalonians 2:7),
God is sovereign and the victory of His Son, Jesus Christ, is complete as revealed in Ephesians
1:20-23,  "...which He worked in Christ, when He raised Him from the dead, and made Him to sit at His
right hand in the heavenly places, far above all rule and authority and power and dominion, and
every name that is named, not only in this age but also in that which is to come.  He put all things in
subjection under His feet, and gave Him to be head over all things for the assembly, which is His
body, the fullness of Him who fills all in all."  Amen
