If you said ‘Satan’ you are wrong. The scriptures make it clear that Jesus and Jesus alone is King of King and Lord of Lords.
Colossians 1:15-18 We look at this Son and see the God who cannot be seen. We look at this Son and see God’s original purpose in everything created. For everything, absolutely everything, above and below, visible and invisible, rank after rank after rank of angels—everything got started in him and finds its purpose in him. He was there before any of it came into existence and holds it all together right up to this moment. And when it comes to the church, he organizes and holds it together, like a head does a body.
Jesus is the Glue holding the universe together
Before you laugh about this, keep in mind that astronomers recognize that there is something in so-called empty space. They liken it to a net or gaseous medium. https://www.thoughtco.com/whats-in-the-space-between-stars-3073688
Christians now have authority over the demonic
As the one who created all the angels, including those who rebelled and became demonic, Jesus still is boss over them no matter where they are. He gave to us, to His believers the authority to control these demonic forces in His name. But do we do this?
In other words, the control of the demonic on the earth today belongs in the hands of the believers. Jesus will deal with Hell and its residents in due time. We will not be there.
