If God is all-powerful, all-knowing, and perfectly good, why is there so much evil and suffering in the world? For many people, this isn’t merely one objection to Christianity among several. It’s the objection. A universe containing cancer, earthquakes, war, child abuse, genocide, starvation, dementia, birth defects, and apparently pointless suffering doesn’t immediately look like the work of a loving and omnipotent God. Christians can offer philosophical arguments for God’s existence, evidence for the resurrection, and arguments for the reliability of Scripture, but sooner or later we have to face the obvious question: If this God exists, why does His world look like this?
We shouldn’t rush past the force of that question. Sometimes Christians answer suffering so quickly that our defense of God becomes almost offensive to the person who’s actually suffering. It’s easy to discuss free will when the example is an abstract murderer in a philosophy textbook. It’s considerably harder when a parent has just buried a child. The problem of evil is therefore both an intellectual problem and an existential problem, and those two dimensions shouldn’t be confused. A philosophical explanation may show that God’s existence and evil aren’t logically contradictory, but that doesn’t mean the explanation will comfort someone standing beside a hospital bed. Sometimes the right apologetic answer is an argument. Sometimes it’s sitting quietly with somebody who hurts.
What Do We Mean by Evil?
Before asking why God permits evil, we need to distinguish several kinds of suffering. Moral evil results from the choices and actions of moral beings: murder, rape, abuse, exploitation, cruelty, oppression, betrayal, and war. Human beings do these things to one another, and any explanation of moral evil has to take human agency seriously. If God creates beings capable of meaningful moral choice, what happens when they use that freedom destructively?
Natural evil is more difficult because nobody chooses an earthquake, childhood leukemia, a hurricane, or a genetic disorder. Animals suffered, predators killed prey, diseases existed, and natural disasters occurred long before any living human being made a moral decision—at least according to the conventional scientific history of the earth. Christians therefore can’t answer every form of suffering simply by saying, “God gave us free will.” Free will may explain why a man pulls a trigger. It doesn’t immediately explain why a five-year-old develops brain cancer.
The Logical Problem of Evil
The strongest traditional form of the objection argues that God and evil are logically incompatible. If God is perfectly good, He would want to eliminate evil. If He’s all-powerful, He could eliminate evil. Evil exists. Therefore, the argument concludes, the traditional Christian God cannot exist. Put that way, the problem appears devastating because Christianity seems to affirm three propositions that can’t all be true at once: God is omnipotent, God is perfectly good, and evil exists.
But there’s a missing premise: that a perfectly good and omnipotent God could have no morally sufficient reason for allowing evil. Once that possibility is introduced, the logical contradiction disappears unless the critic can show that God couldn’t possibly have such a reason. Perhaps some goods require genuine freedom. Perhaps courage, forgiveness, sacrifice, perseverance, and certain forms of love can exist only in a world where suffering is possible. Perhaps God’s purposes extend beyond our present lives. We don’t have to prove that any particular explanation accounts for every evil before recognizing that God’s existence and evil aren’t formally contradictory.
The Evidential Problem of Evil
That doesn’t make the problem disappear. The more difficult contemporary argument is often the evidential problem of evil. Instead of claiming that any evil makes God’s existence impossible, it asks whether the amount, intensity, and apparently pointless distribution of suffering make the Christian God unlikely. Even if God has reasons for allowing some suffering, why this much? Why Auschwitz? Why children dying slowly from disease? Why animals suffering for millions of years? Why earthquakes that kill thousands indiscriminately? Why couldn’t an omnipotent God accomplish His purposes with considerably less misery?
That’s a much harder question, because saying “free will” or “soul-making” doesn’t obviously explain every case. A world containing meaningful freedom might require the possibility of murder, but does it require childhood cancer? Character might develop through adversity, but surely some suffering destroys people rather than improving them. The Christian therefore shouldn’t act as though one philosophical answer solves the entire problem. Different forms of evil may require different explanations, and some suffering may remain mysterious even after we’ve developed a coherent overall theology of evil.
Free Will
The free-will defense is probably Christianity’s best-known response to moral evil. God could have created creatures incapable of doing anything wrong, but it’s not obvious that such creatures would possess morally significant freedom. A robot programmed to say “I love you” isn’t loving you in the same sense as a person who freely chooses a relationship with you. If God values creatures capable of genuine love, obedience, courage, generosity, and moral responsibility, then He may permit the possibility that those same creatures will choose hatred, rebellion, cruelty, and selfishness.
Notice what the argument does and doesn’t accomplish. It can explain why an omnipotent God might permit the possibility of moral evil, but it doesn’t mean God approves of the evil choices people make. Nor does human freedom require God never to intervene. Christians believe He sometimes does intervene, which raises the further question of why He intervenes in one situation and apparently not another. Free will gets us somewhere important, but it doesn’t get us all the way home.
Couldn’t God Create People Who Always Freely Choose Good?
This objection sounds simple but contains a surprisingly difficult philosophical question. Could God create genuinely free people and simultaneously guarantee that they always freely choose the good? If their choices are genuinely undetermined in the relevant sense, guaranteeing every choice in advance seems difficult. On the other hand, Christian theology expects redeemed people eventually to exist in a state where rebellion and evil no longer characterize human life, which naturally raises the question of why God didn’t simply begin there.
One possible answer is that there may be a meaningful difference between created innocence and developed character. A person who has freely learned trust, love, obedience, courage, and dependence upon God may possess something that couldn’t simply be installed like software. I wouldn’t pretend that completely answers the question, because we don’t know enough about possible worlds, human freedom, or God’s purposes to demonstrate exactly what God could have created. But the burden on the logical objection is substantial: it has to show not merely that we can imagine a better world, but that God could achieve all His intended goods in that world without sacrificing something of equal or greater importance.
Freedom Has Consequences
Sometimes we want freedom without consequences. We want human beings capable of genuine choice, but we’d also like God to prevent the consequences whenever those choices become sufficiently terrible. A man can decide to shoot someone, but perhaps God should make the gun jam. A dictator can order genocide, but perhaps every vehicle should fail, every weapon malfunction, and every soldier become mysteriously incapable of carrying out the order. At some point, however, we have to ask what a world like that would actually be.
If God continuously manipulated physical reality so that evil intentions could never produce serious consequences, we’d inhabit a strange moral theater in which actions no longer reliably matter. Fire might burn wood unless someone intended to burn a house. Gravity might operate normally unless someone pushed another person from a building. Bullets might work at a firing range but disappear when aimed maliciously. A stable world in which morally significant action is possible appears to require that actions normally produce predictable consequences, even when those consequences are terrible.
Natural Laws
That observation helps with natural evil as well. The same physical regularities that make life possible can also produce suffering. Gravity keeps us on the earth, but gravity can kill someone who falls from a cliff. Tectonic activity contributes to the geological processes of a dynamic planet, but earthquakes can devastate cities. Weather systems distribute heat and water while sometimes producing destructive storms. Biological reproduction allows life to continue while genetic mutations can cause devastating disease.
This doesn’t explain why God selected these particular laws or why He doesn’t intervene more frequently, but it challenges the assumption that a good world must be one in which nothing can hurt us. A world capable of sustaining embodied, interacting, morally responsible creatures may require stable natural processes. We shouldn’t commit the same mistake here that we warned about in creationism: discovering a natural mechanism doesn’t eliminate God. But neither should Christians say “the fall caused earthquakes” as though that statement by itself explains the physics. The theological and physical questions aren’t identical.
The Fall
Christian theology doesn’t describe the world as it presently exists as everything God intends creation to be. Genesis portrays humanity rebelling against God, after which alienation, pain, toil, conflict, and death become defining features of human existence. Paul later describes creation itself as subjected to futility and groaning while awaiting liberation. Christianity therefore approaches evil from within a story: creation, fall, redemption, restoration.
That framework is important, but we need to be careful about what we claim it explains. Saying “the world is fallen” gives us a theological category for disorder; it doesn’t tell us exactly how every disease, earthquake, mutation, predator, or hurricane relates historically to Adam’s sin. That question becomes especially complicated for Christians who accept an ancient earth containing animal death and natural catastrophe long before human beings appeared. Young-earth and old-earth Christians will therefore develop this part of the explanation differently. We shouldn’t make the fall answer questions the biblical text itself doesn’t explicitly answer.
Natural Evil and Human Responsibility
Not everything we call a natural disaster is entirely natural in its consequences. An earthquake may be unavoidable, but whether buildings collapse can depend upon engineering standards, poverty, corruption, and government decisions. Drought becomes famine partly because of agriculture, infrastructure, war, economics, and distribution. Disease outcomes can depend upon sanitation, medical access, political stability, and whether wealthy societies are willing to help poorer ones.
That doesn’t remove the problem of natural evil, but it complicates it. We sometimes ask why God allows suffering while ignoring the suffering human beings could reduce and don’t. It’s easier to ask why God permits starvation than to ask why people with abundance tolerate a world in which others starve. That observation shouldn’t be used to blame victims or let God off the philosophical hook. It simply means the boundary between moral and natural evil isn’t always as clean as our textbook categories suggest.
Soul-Making
Another important response is sometimes called the soul-making theodicy, associated historically with Irenaeus and developed in modern philosophy by John Hick. The basic idea is that God isn’t merely interested in keeping us comfortable. He’s forming persons capable of courage, compassion, patience, faithfulness, sacrifice, and mature love. A world containing no danger, difficulty, uncertainty, or suffering would eliminate many of the circumstances in which those virtues develop.
There’s clearly something true here. Courage requires something worth fearing. Forgiveness requires wrongdoing. Compassion requires someone who suffers. Perseverance requires difficulty. But we shouldn’t turn that insight into the claim that every tragedy exists because God wanted to teach somebody a lesson. Some suffering appears to crush people rather than develop them. A child who dies at two years old isn’t obviously receiving decades of character formation through the experience. Soul-making may explain why a world containing adversity can serve valuable purposes, but it doesn’t provide a tidy explanation for every individual tragedy.
“Everything Happens for a Reason”
This is one of those Christian phrases I would use very carefully, especially around suffering. At one level, Christians believe God is sovereign and that history isn’t outside His ultimate purposes. But when someone has just lost a spouse, saying “everything happens for a reason” can sound like we’re telling them God deliberately arranged the tragedy because He needed another angel—which isn’t biblical anyway—or because He wanted to teach them something.
Romans 8:28 says that God works in all things for the good of those who love Him. That’s not the same thing as saying everything that happens is good. The cross itself demonstrates the difference. Human beings committed an act of terrible injustice, yet God brought redemption through it. Christianity’s claim isn’t that evil secretly becomes good if we look hard enough. It’s that God is capable of bringing good even out of genuine evil.
The Cross Changes the Question
Christianity’s response to suffering becomes distinctive at the cross because God doesn’t remain safely removed from the problem. The Christian claim is that in Jesus Christ, God entered the human condition and experienced rejection, betrayal, injustice, torture, abandonment, and death. That doesn’t answer every philosophical question about why God permits suffering, but it changes the picture of the God we’re questioning.
When Christians say God understands suffering, we aren’t merely saying an omniscient being possesses information about it. Christ suffered. He wept at Lazarus’s tomb even though He was about to raise Lazarus from the dead. He experienced anguish in Gethsemane. He cried out from the cross. Whatever explanation Christianity eventually gives for evil, it cannot be the explanation of a distant God who watches human misery from a comfortable corner of the universe. The God Christianity proclaims has entered it.
Why Doesn’t God Stop It?
This may be the hardest form of the question because Christians believe God sometimes does intervene. We pray for healing because we believe God can heal. We pray for protection because we believe He can protect. Scripture contains miraculous rescues, deliverances, healings, and judgments. If God never intervened, we could simply say He created an orderly world and allows its processes to run. But Christianity says He does intervene, which naturally makes us ask why He apparently didn’t intervene somewhere else.
Why does one person survive an accident while another dies? Why does one cancer disappear while another progresses? Why does one child escape an abuser while another doesn’t? I don’t have an answer that makes those individual cases intellectually tidy, and I don’t trust anyone who claims to possess God’s private explanation for every tragedy. Christians can affirm providence without pretending we can read providence perfectly. “I don’t know why God allowed this” is sometimes a much more faithful answer than inventing a reason God hasn’t revealed.
Divine Hiddenness
The problem of evil overlaps with another objection: Why is God so hidden? If God loves people and wants them to know Him, why doesn’t He make His existence unmistakable? Why do sincere people search for God and remain unconvinced? Why doesn’t God simply appear publicly and settle the question?
One answer is that overwhelming evidence of God’s existence wouldn’t necessarily produce love or obedience. Scripture itself portrays people knowing God exists and still resisting Him. But that doesn’t completely answer the objection because a relationship normally requires some degree of recognizable presence. Christians therefore point to creation, conscience, Scripture, Christ, religious experience, and the work of the Spirit as ways God makes Himself known while acknowledging that His presence isn’t coercively obvious. Whether that level of revelation is sufficient becomes part of the broader cumulative case for Christianity.
Why Doesn’t God Explain Himself?
The book of Job is especially interesting because Job desperately wants an explanation for his suffering, and readers know something he doesn’t. We see the heavenly prologue; Job doesn’t. Yet when God finally speaks, He doesn’t give Job a detailed philosophical theodicy. Instead, He confronts Job with the enormous difference between divine and human knowledge.
That can sound like a religious way of saying, “Stop asking questions,” but I don’t think that’s the point. Job is permitted to question, lament, protest, and wrestle throughout the book. The issue is whether his inability to identify a sufficient reason means no sufficient reason exists. If God possesses vastly greater knowledge than we do, then we should at least allow the possibility that some reasons for permitting suffering lie beyond our present understanding. That doesn’t prove God has such reasons. It does challenge the inference from “I can’t see a good reason” to “there cannot be one.”
Skeptical Theism
Philosophers sometimes call that approach skeptical theism. The basic point is modest: if God exists and possesses unlimited knowledge while human beings possess extremely limited knowledge, we shouldn’t expect to understand every reason God has for permitting particular events. A child may be unable to understand why a surgeon hurts him during a medical procedure even though the parent understands the larger purpose. The difference between divine and human understanding would presumably be vastly greater still.
But this approach can be pushed too far. If we say we can never understand God’s reasons, we risk undermining our ability to make moral judgments about anything God supposedly does. Christianity doesn’t teach that good and evil become meaningless when applied to God. So skeptical theism should encourage epistemic humility, not intellectual surrender. We can recognize our limited perspective without using mystery as duct tape over every theological problem.
Horrendous Evil
Some suffering seems so severe that ordinary appeals to character development sound almost insulting. Genocide, torture, sexual abuse, the murder of children, and other forms of what philosophers sometimes call horrendous evil raise a deeper question: Can any future good really overcome what has happened? If a person suffers unimaginably and then dies, saying the event contributed to somebody else’s character formation seems morally inadequate.
Christianity’s strongest answer here isn’t that the evil wasn’t really so bad. It is that this life isn’t the whole story. Resurrection, judgment, restoration, and eternal life dramatically change the moral horizon. If death is the absolute end, some evils appear permanently victorious. If God raises the dead, judges evil, restores what has been broken, and grants eternal life, then earthly suffering doesn’t receive the final word. That doesn’t make the suffering insignificant. It means God has eternity in which to make right what we cannot make right.
Heaven Matters to the Argument
Sometimes heaven is dismissed as a convenient religious escape hatch: suffer now and receive compensation later. That’s a caricature of the Christian hope. Christianity doesn’t merely promise a pleasant afterlife in which people forget what happened. It promises resurrection and restoration, the defeat of death, judgment of evil, and a renewed creation in which suffering no longer dominates human existence.
If Christianity is false, that promise offers no solution. But when we’re evaluating whether Christianity contains a coherent response to evil, we’re not allowed to remove half of Christian theology and then complain that what’s left can’t solve the problem. The Christian story doesn’t end at a grave. The same Christianity that has to explain why God permits suffering also claims that God will ultimately abolish it.
Hell and the Problem of Evil
Of course, Christian teaching about final judgment creates another problem rather than simply solving one. If eternal life helps answer the problem of earthly suffering, what do we do with biblical warnings about hell and final punishment? A theology in which God eventually causes or permits endless suffering would seem to intensify the very problem we’re trying to solve.
Christians disagree significantly about the nature and duration of final punishment, including traditional eternal conscious punishment, conditional immortality, and various understandings of the biblical imagery. Those questions deserve separate treatment. But whatever position we adopt, we can’t use final judgment as part of our solution to evil without also asking whether our doctrine of judgment is consistent with God’s justice and goodness. Theodicy doesn’t stop at death.
Animal Suffering
Animal suffering is one of the more difficult forms of the problem because animals don’t appear to undergo suffering as a consequence of their own moral choices. Predation, disease, injury, starvation, parasitism, and extinction have characterized animal life throughout natural history if conventional paleontology is correct. That raises serious questions for old-earth creation models in particular.
We can point to ecological systems, evolutionary development, the stability of natural laws, and the possibility that animal pain serves survival functions, but none of those explanations makes prolonged animal suffering emotionally easy to understand. Scripture portrays God’s concern for animals and ultimately speaks of creation itself participating in restoration. Beyond that, I think Christians should be willing to admit that animal suffering remains one of the harder pieces of the puzzle rather than pretending we’ve solved it with a sentence about the fall.
Does Evil Actually Point Toward God?
There’s an interesting reversal of the problem that Christians sometimes make. When we call something evil, what do we mean? If the universe is ultimately nothing more than matter, energy, and unguided physical processes, can anything be objectively evil, or do we merely mean that we strongly dislike it? A lion killing a gazelle isn’t morally evil. If human beings are entirely products of the same purposeless natural processes, where does objective moral obligation come from?
That’s a legitimate question, but Christians should use it carefully. Telling a grieving parent, “Your child’s death proves objective morality and therefore God” would be grotesque pastoral care. As a philosophical argument, however, the problem is real. The objection from evil frequently assumes that some things are really wrong, not merely unpleasant or socially disapproved. If objective moral values exist, their foundation requires explanation. The problem of evil may therefore create a problem for theism while simultaneously raising difficult questions for naturalism.
Atheists Can Recognize Evil
None of that means atheists can’t recognize evil, behave morally, or care deeply about suffering. Obviously they can. The question isn’t whether atheists can be moral. The question is what ultimately grounds objective moral truths if reality contains nothing beyond the natural world. A person doesn’t need to understand the philosophical foundation of morality in order to recognize cruelty any more than someone needs to understand optics in order to see.
Christians should therefore avoid the foolish argument that disbelief in God makes someone personally immoral. Some atheists live morally admirable lives, and some Christians behave terribly. The philosophical question concerns the foundation of moral obligation, not the behavior of individual believers and unbelievers. Keeping those issues separate makes the argument both fairer and stronger.
The Problem of Evil Works Both Ways
There is therefore a strange tension in the argument. Evil can make God’s existence difficult to understand because a good God seems inconsistent with terrible suffering. Yet our outrage at evil seems to assume that reality contains a moral standard according to which things ought not be this way. We don’t merely dislike genocide the way we dislike a bad smell. We believe genocide is genuinely wrong even if a society approves of it.
That doesn’t prove Christianity. A secular philosopher can develop theories of objective morality without God, and those theories deserve serious consideration. But the problem of evil isn’t philosophically cost-free for the skeptic. If we’re going to use objective evil as evidence against God, we should also ask what makes evil objectively evil in the worldview we’re proposing instead. Everybody has homework.
Don’t Give Cheap Answers
There are moments when Christians should stop doing apologetics and start being Christians. If someone’s daughter has just died, that’s probably not the moment to explain Alvin Plantinga’s free-will defense. Job’s friends actually did reasonably well for seven days when they sat with him in silence. The trouble started when they began explaining why everything had happened.
Jesus Himself doesn’t respond to suffering with detached philosophical analysis. He weeps. He heals. He feeds people. He confronts evil. He tells His followers to care for those who suffer. Christianity doesn’t merely ask us to explain evil. It commands us to fight it. Feeding the hungry, caring for the sick, protecting children, resisting injustice, comforting the grieving, and praying for healing are themselves part of the Christian response to a broken world.
Christianity Doesn’t Say Suffering Is Good
This distinction matters. Christianity doesn’t require us to look at cancer, murder, abuse, or death and call them good because God can use them. Jesus treated sickness as something to heal and death as an enemy. Paul explicitly calls death “the last enemy.” Revelation doesn’t end with everyone finally learning to appreciate suffering; it ends with death, mourning, crying, and pain passing away.
God can redeem suffering without suffering becoming good. He can produce courage from danger, forgiveness from wrongdoing, compassion from pain, and redemption from the cross without declaring the original evil desirable. The Christian hope isn’t that we’ll eventually understand why evil was wonderful. It’s that evil will eventually lose.
Could God Have Made a Better World?
Maybe. We should be cautious about pretending we know every possible world God could have created. I can certainly imagine worlds containing less suffering than ours. I can imagine a world without childhood cancer, Alzheimer’s disease, tsunamis, or mosquitoes, and I’m not particularly worried about losing the mosquitoes. The philosophical question, however, isn’t whether I can imagine individual improvements. It’s whether I understand all the consequences of changing the network of physical laws, biological processes, human freedoms, historical relationships, and divine purposes that make our world what it is.
Christians shouldn’t answer this by claiming that ours must therefore be the best of all possible worlds. I don’t know that, and Scripture doesn’t require me to believe it. Christianity makes a different claim: God has purposes in permitting a world containing genuine evil and suffering, He can redeem what evil destroys, and the present world isn’t the finished product. The biblical story is moving somewhere.
Where Is God When We Suffer?
The philosophical answer might discuss free will, natural laws, soul-making, limited human knowledge, and eternal restoration. The Christian answer eventually points to a person. Where is God when human beings suffer? On the cross. Not only there, of course, but the cross prevents Christians from imagining God as detached from the pain of His creation.
And then Christianity points beyond the cross to an empty tomb. That matters enormously. If Jesus merely suffered with us and then remained dead, Christianity could offer divine solidarity but not final victory. The resurrection changes the claim. God doesn’t merely enter suffering; He defeats death. The Christian answer to evil is therefore ultimately not a philosophical theory but a story moving from creation through fall and redemption toward resurrection and restoration.
Does the Problem of Evil Disprove God?
I don’t think it does. The logical problem doesn’t demonstrate a contradiction unless we can show that God couldn’t possibly have morally sufficient reasons for permitting evil. Free will, stable natural laws, character formation, human limitation, redemption, and eternal restoration provide plausible categories within which such reasons can exist. The evidential problem is harder because some suffering appears overwhelmingly excessive and pointless from our perspective. Christians shouldn’t minimize that difficulty.
But we also need to compare complete worldviews rather than examining Christianity in isolation. Naturalism removes the theological question of why God permits suffering, but it doesn’t remove suffering. It gives us a universe in which suffering ultimately happens because indifferent natural processes produce organisms capable of experiencing pain. Christianity has to explain why God permits evil. Naturalism has to explain objective moral outrage, meaning, consciousness, and why suffering is anything more than an unfortunate biological experience. Neither worldview gets to ask all the questions while answering none.
The Christian Answer Is Ultimately a Promise
There are questions about evil I can discuss philosophically, and there are questions for which I don’t think we possess enough information to give a satisfying answer. Why did God allow that particular child to die? Why did He permit that particular atrocity? Why did one person receive healing while another equally faithful person didn’t? I don’t know, and I’m not going to invent an answer and attribute it to God.
Christianity ultimately gives us something different from a complete explanation of every tragedy. It gives us a promise. Evil won’t have the last word. Suffering won’t have the last word. Cancer won’t have the last word. Abuse won’t have the last word. Injustice won’t have the last word. And death won’t have the last word.
The Christian story ends not with human beings finally learning why suffering was necessary, but with God making all things new.
That doesn’t answer every question we have today.
But if the resurrection of Jesus is true, it gives us a reason to believe the story isn’t over yet.
