Paul writes about thrones created in heaven and earth, visible and invisible.
For by him were all things created, that are in heaven, and that are in earth, visible and invisible, whether they be thrones, or dominions, or principalities, or powers: all things were created by him, and for him: (Colossians 1:16)
The Greek word for thrones is "thronos", meaning a stately (royal) seat, implying power or ruler.
But I say unto you, Swear not at all; neither by heaven; for it is God's throne: (Matthew 5:34)
He hath put down the mighty from their seats, and exalted them of low degree. (Luke 1:52)
I know thy works, and where thou dwellest, even where Satan's seat is: and thou holdest fast my name, and hast not denied my faith, even in those days wherein Antipas was my faithful martyr, who was slain among you, where Satan dwelleth. (Revelation 2:13)
"Thrones" could refer to heavenly or earthly kingdoms and power. Paul sought to encourage the Colossian Christians, reminding them that no power can exist except by the permission of the Great Lord of All, the One Who sits upon the Throne of All Creation, Jesus Christ, Redeemer and Lover of Our Souls. The One Who died for us arose from the dead and is Sovereign over all creation and authority.
