Adam & Eve
After God created the earth and all that’s in it, He put Adam and Eve in charge of it. They were the first to have been given dominion over His creation.
Then God blessed them, and God said to them, “Be fruitful and multiply; fill the earth and subdue it; have dominion over the fish of the sea, over the birds of the air, and over every living thing that moves on the earth.” Genesis 1:28
He also instructed them that they could eat from any tree in the garden of Eden except from the tree of the knowledge of good and evil. Their spiritual and natural lives depended on their obedience to this command. If they were to disobey and eat from that tree, they would die.
After Adam and Eve were instructed concerning the forbidden tree, Satan shows up and entices them to disobey what God had told them. We know from Romans 6:16 that we are servants to the one whom we obey. They chose to act upon the council of the deceiver and as a result, he became their new master. Their dominion over the earth became his dominion and they became his servants, servants to sin in the kingdom of darkness.
The deceiver succeeded in usurping dominion from Adam and Eve and in effect he became the god of this world. In response to this, God immediately revealed His intention to restore dominion back to the godly in the first recorded prophecy.
“And I will put enmity between you and the woman, and between your seed and her Seed; He shall bruise your head, and you shall bruise His heel.” Genesis 3:15
In hindsight, we know that this spoke of the conflict that happened some two thousand years ago when Jesus first came to earth. He lived a life of perfect obedience to the Father and offered Himself as the perfect sacrifice for the sins of the world. Satan was able to bruise His heel in that through Judas, he successfully schemed to put Jesus to death. Jesus bruised Satan's head in that by virtue of His sinless life and death on the cross, He was found worthy to be given all authority in heaven and on earth. This put an end to Satan’s claim
as the god of this world even though he is allowed to function in that capacity for the time being. The return of Jesus will bring about the manifestation of Satan’s defeat when he is cast into the abyss and the kingdom of God is established on earth.
