The fire of Hell is figurative, because unlike a natural fire that eventually burns out, the fire of Hell never does. This is very good reason not to believe that Hell is an actual physical fire, but is an actual physical place. As we need to lock up some people in jail for life, the unsaved need to be locked up in Hell for eternity. As it is in heaven so it is on earth. There is no physical fire in prisons.

God is not a sadist so the fire is a fire of judgment. He uses such expressive language so that if you don't respond to His love, you might respond to His judgment.

The Devil is a real being and so are the angels. They are never figurative. Are you saying you think they are not real beings?

In your profile you suggest that you are a Christian, but that appears not to be the case given your stance on Hell, Satan and the angels. What Christian believes angels are merely allegory or hyperbole and Hell is just a blazing pit of physical fire. That's absurd!

Hell is the perfect place designed by God for those who eternally reject God. It's the perfect eternal prison for the unregenerate.
