I saw this theory today on another video besides this one. Bear with me, it's weird.
People are teaching that the sun is the lake of fire.
"Our sun is a lake of fire. If you were to stand upon the surface of the sun you would be in a lake of fire. At the same time as you would look from the sun, all that you would see is the blackness of space. Look at Matthew 22:13 where Jesus speaks of an unsaved man being cast into hell. "Then said the king to the servants, Bind him hand and foot, and take him away, and cast him into outer darkness; there shall be weeping and gnashing of teeth." Scientists tell us that our sun is moving. They say it is in orbit as are all other stars. So we see how these facts about hell given in the Bible could be a description of our sun or many different suns. Hell is a lake of fire (Revelation 20:10) and the blackness of darkness forever (Jude 13), and those in hell are described as wandering stars (Jude 13). Therefore, we conclude that hell could be a star or many stars in outer space. We will certainly find out one day."
I do not know anything in the Bible that says this. If I am wrong and missed the verse, tell me where it says different.
People get some really odd ideas out there. Always make sure to test them by God's Word.
