What is the Lake of Fire?

Question 10100.

The lake of fire is the final and permanent place of judgement for Satan, for the beast and the false prophet, and for every person whose name is not written in the book of life. I want to say that plainly at the start, because this is one of those subjects where people would rather I hedged. The phrase belongs to John, and he uses it five times in the last three chapters of Revelation, always with the same terrible finality.

I have never enjoyed preaching on this. I do not know any pastor worth his salt who does. Yet if I skip it, I am editing the Bible for the comfort of my hearers, and that is not a kindness. So let us look at what the text says about the lake of fire, what it does not say, and why I am persuaded that the traditional understanding is the one that fits the words on the page.

Where the phrase comes from

The expression appears only in Revelation, at Revelation 19:20, then again at 20:10, 20:14 twice, 20:15 and 21:8. The Greek behind it is straightforward: limne, a lake or pool, joined to pur, fire. John is not reaching for an obscure metaphor. He is describing a place, and he locates it at the end of the prophetic timeline rather than in the middle of it.

That location matters. The lake of fire is not the first thing that happens to the wicked after death, and it is not a general word for the afterlife of the lost. It is the destination reached after the Great White Throne, when the books are opened and the second resurrection has taken place. If you want the sequence in more detail I have set it out in my answer on the Great White Throne judgement.

So the lake of fire is an end point. Nothing in Revelation suggests anyone passes through it and comes out the other side. Every reference is a consignment, never a stage. Whenever John wants to describe a temporary condition he has other vocabulary available, and he uses it. Here he does not, and the silence is eloquent. The grammar of these verses gives us people being put somewhere and staying there, which is precisely why the passage has troubled readers for nineteen centuries.

The lake of fire and the second death

John gives us his own definition, which saves a great deal of speculation. Death and Hades are thrown in, and then he writes that this is the second death, the lake of fire. He is telling us that the two expressions describe the same reality from two angles.

The first death is the separation of spirit and soul from body. The second death is separation from the life of God, made permanent and irreversible in the lake of fire. It is death in the biblical sense of ruin and separation, not death in the sense of ceasing to exist. A car left rusting in a field has not stopped existing; it has stopped functioning as what it was made to be. That analogy limps, as all analogies do, but it catches something of the horror.

I have written separately on what the second death means, and the two answers belong together. What I would stress here is that John links the second death and the lake of fire in one breath, so any interpretation that empties one of meaning empties both.

Who is thrown into the lake of fire

Revelation names its occupants with unusual precision. The beast and the false prophet go in first, at the Second Coming, and they are still there a thousand years later when the devil joins them. That detail alone is worth pausing over, because it settles the question of whether the fire consumes what it receives.

Then comes Death and Hades. The intermediate holding place for the unsaved dead is emptied and then abolished, which is a strange thing to say about an abstraction and a much more sensible thing to say if John is describing the end of a real state of affairs. Finally, anyone whose name is not found in the book of life is thrown into the lake of fire.

Notice what the criterion is. It is not the size of the sin ledger. It is the absence of a name from a register. The question at the last is not whether you were respectable but whether you belong to the Lamb who was slain.

Is the fire literal?

I hold the language loosely at this one point, and I want to be honest about why. Fire and outer darkness are both used of the same destiny, and a lake that burns and a darkness that is outer are hard to hold in the same photograph. Revelation is a book that gives us real things through vivid pictures, and I am content to say that the reality is at least as dreadful as the picture rather than less.

What I will not do is use the possibility of imagery to soften the thing imaged. When Jesus spoke of Gehenna he used the rubbish tip outside Jerusalem as his picture, and nobody in his audience heard that as reassuring. If the lake of fire is a symbol, it is a symbol chosen by God to convey something that no gentler symbol could carry.

There is also the sulphur. John twice adds it, and the smell of burning sulphur was familiar to anyone who had seen the Dead Sea region or heard the story of Sodom. The associations are deliberate.

One further point on the language. Fire in Scripture is not only destructive; it is also the standard image of the holiness of God himself. He is a consuming fire, and the same presence that is warmth and glory to those who love him is unbearable to those who will not have him. That gives the lake of fire a moral logic rather than an arbitrary cruelty. It is not that God invents a torture chamber; it is that unrepentant sinners are brought at last into full contact with the reality of God with nothing between them and it, and there is no shelter left because the shelter was Christ and they refused him. Read that way, the imagery of the lake of fire is not a departure from the character of God but an unveiling of it.

Hades and the lake of fire are not the same

This is where a good deal of popular confusion lives. People use hell as a single word for everything after death, and then they read Revelation 20:14 and wonder how hell can be thrown into hell.

Scripture distinguishes them. Hades is the intermediate state for the unsaved between death and resurrection, a real condition of conscious separation described in Luke 16. The lake of fire is the final condition after the second resurrection and the Great White Throne. One is a remand wing, the other is the sentence. I have laid out the wider vocabulary in my answer on what hell is.

Keeping the two apart tidies up several other questions. It explains why the rich man in Luke 16 is in torment before any final judgement has occurred, and it explains why the last judgement is a formal, public, evidential occasion rather than an arbitrary one.

Why I hold to eternal conscious punishment

The decisive text for me is Matthew 25:46, where the same adjective governs both destinies in a single sentence. If eternal life is unending, then eternal punishment is unending, and no amount of lexical footwork changes that without doing violence to the grammar.

Revelation 20:10 adds the direct statement that the devil, the beast and the false prophet will be tormented day and night for ever and ever. The phrase is the strongest expression of endlessness the Greek language had, and John uses it elsewhere of the worship of God himself.

Then there is the simple observation I made above about the beast surviving a thousand years in the lake of fire. Whatever that place does to its occupants, it does not extinguish them.

What annihilationism misses

I understand the pastoral pressure behind annihilationism. It offers a way of holding on to judgement while removing its endlessness, and it can be argued with real seriousness by people who love the Bible. I still think it fails at the level of the text.

It leans heavily on the word destruction, treating it as extinction, when the biblical usage regularly means ruin rather than non-existence. Wineskins are destroyed and still lie on the floor. It also has to strain Matthew 25:46 in the way I described, and it has no good answer to Revelation 20:10. I have set out the case at length in my answer on annihilationism.

My concern is not to win an argument. It is that a doctrine which reduces the stakes will always, in time, reduce the urgency. Missionary history bears that out with painful consistency.

What the Old Testament had already said

John did not invent this picture out of nothing. Daniel 12:2 speaks of many who sleep in the dust awaking, some to everlasting life and some to shame and everlasting contempt, and the two destinies are set side by side there exactly as Jesus sets them side by side in Matthew 25. Isaiah closes his prophecy with the bodies of the rebels and a fire that is not quenched, and Jesus quotes that line when he warns about Gehenna. The lake of fire is the terminus of a road the prophets had already mapped, and the New Testament is filling in the detail rather than changing the direction of travel.

That continuity is worth pressing, because people occasionally suggest that the God of the Old Testament was harsh and that Jesus softened him. The plain fact runs the other way. The most sustained and severe teaching about final judgement in the whole Bible comes from the lips of Jesus himself, and he gives it in the same breath as his invitation to come to him and find rest. The tenderness and the warning are not in competition; they come from the same heart and the same mouth.

There is also a pattern in the way God has dealt with the world before. The flood, Sodom, the exile: each is a real historical judgement that the New Testament treats as a foreshadowing of the last one. Peter makes that argument directly. If we take those events as history, we have no principled reason to treat the final judgement as poetry.

Degrees of punishment and the justice of God

One thing the lake of fire is not is a flat, undifferentiated sentence handed out without regard to what a person did. The Great White Throne is an evidential judgement. The books are opened. The dead are judged according to their works. Jesus spoke of servants beaten with many stripes and servants beaten with few, and he said it would be more bearable for Sodom on the day of judgement than for the towns that had watched him work and shrugged.

That tells me two things. It tells me that God is scrupulously just, and that no one will ever be able to say the sentence exceeded the crime. It also tells me that light received carries weight. The most exposed people on earth, in terms of accountability, are those who have heard the gospel clearly and repeatedly and have quietly declined it. Familiarity with the message is not the same as receiving it.

I have written separately on degrees of punishment, because it is one of those doctrines that quietly answers the objection about proportionality before the objection is even raised.

The lake of fire and the character of God

People sometimes put it to me that a loving God could not do such a thing. I understand the feeling, and I would rather sit with someone in that difficulty than dismiss it. But love that is indifferent to evil is not love; it is sentiment wearing love as a coat.

The cross is the answer to the objection, not the exception to it. God did not deal with sin by waving it away. He dealt with it by bearing it himself, in the person of his Son, so that no one need ever face the lake of fire. The offer is genuine and it is universal. Jesus died for the sins of the whole world, and the invitation of Revelation 22:17 stands open to the last verse of the Bible.

That is why I can preach on the lake of fire without despair. The doctrine is not a threat God enjoys making. It is the shape of what love refuses to force.

So, now what?

If you are reading this and you do not know whether your name is in the book of life, that is the only question worth your attention today. It is settled not by improvement but by trust. Christ crucified and risen has taken the judgement that belonged to you, and he gives eternal life to all who receive him.

If you are a believer, let this doctrine do two things in you. Let it make you tender rather than smug, because you were not saved by being better than your neighbour and you have nothing to be superior about. And let it make you speak, awkwardly if necessary, to the people you love. I have never met anyone who regretted raising the subject clumsily. I have met a good many who regretted the silence they kept until the funeral.

There is also a warning here for preachers, and I include myself. It is possible to hold the doctrine of the lake of fire firmly and never mention it, on the grounds that people find it off-putting. They do find it off-putting. That is rather the point. A doctor who withholds a diagnosis because the patient would rather not hear it is not being kind, and a pulpit that only ever comforts has stopped being a pulpit.

Does the lake of fire frighten you? Good. Fear that drives you to Christ has done its work, and once you are in him the fear has nothing left to feed on. Perfect love casts it out. But it casts it out by dealing with the danger, not by pretending the danger was never there.

Then Death and Hades were thrown into the lake of fire. This is the second death, the lake of fire. And if anyone’s name was not found written in the book of life, he was thrown into the lake of fire.

For Further Study

For the exegetical detail behind this answer, Robert Thomas on Revelation is thorough on the Greek of chapters 19 to 21, and J. Dwight Pentecost gives the prophetic sequence its clearest dispensational treatment in Things to Come. Charles Ryrie and Lewis Sperry Chafer both handle the doctrine within their systematic works, and Millard Erickson surveys the annihilationist debate fairly in Christian Theology. Arnold Fruchtenbaum is worth reading on the Jewish background to Gehenna and its imagery.
