The throne speaks of great authority and on that throne will be Christ in His humanity, which means as God He is perfectly qualified to judge human beings and He will be visible for all to see.  He is not going to be some strange looking creature with an aura around His head.  He will look like one of us but He will have the power to not only destroy the body, but the soul too.  No man ever had this kind of power.  Jesus the Christ does have the power because He is God.  He is in reality what those standing before the Great White Throne of Judgment have denied their entire lives―God the Creator of all things in the heavens and earth.  The judge of all the earth.  He will sit on that throne in all of His glory, holiness and majesty and causing heaven earth to disappear.  Preacher, you ask, “How will that happen?”  Those who stand before Him on that day will be so riveted on His face that heaven and earth will have no place in their vision for anything except Him.
