One of the strongest objections to Christianity sounds like this:

If God is all-powerful, He could stop evil.

If God is perfectly good, He would want to stop evil.

Evil exists. Therefore, God does not exist.

At first glance, the argument feels powerful. And emotionally, it can feel even stronger. Look around. Children suffer. Wars happen. People are murdered. Disease destroys bodies. Natural disasters kill thousands.

If Christians claim God is both good and powerful, how can they explain a world like this?

This is commonly called the problem of evil. And Christians should take it seriously. But there is an important question hiding inside the argument: Does the existence of evil actually make God’s existence logically impossible?

The answer is no. And understanding why requires us to separate several different arguments people often combine together.

The Logical Problem of Evil

The strongest version of the objection says:

God is all-powerful.
God is perfectly good.
Evil exists.
Those three statements cannot all be true.

If that were correct, Christianity would contain a contradiction. But to demonstrate a genuine contradiction, we would need another premise: A perfectly good and all-powerful God could never have a morally sufficient reason for temporarily allowing suffering.

That statement is much harder to prove. Because if God could have morally sufficient reasons for allowing suffering, then God and suffering are not logically incompatible. You may still dislike God’s reasons. You may not know them. But the existence of possible reasons defeats the claim of strict logical contradiction.

Parents Sometimes Allow Pain for Good Reasons

This analogy is limited, but useful. Imagine a young child needs surgery. The parent has the power to stop the procedure. The parent loves the child. Yet the parent allows doctors to cut into the child’s body.

From the child’s perspective, that may seem incomprehensible. Why would someone who loves me allow this pain?

The answer is that the parent knows something the child does not. The pain is connected to a greater purpose.

Now, not all earthly suffering works like surgery. We should never trivialize horrific evil by comparing every tragedy to a temporary medical procedure.

The point is narrower: Allowing suffering is not automatically incompatible with love.

If human beings can sometimes have morally sufficient reasons for allowing pain, it is at least possible that an omniscient God could as well.

Our Knowledge Is Limited

To claim: “There is no possible good reason God could allow this suffering” requires extraordinary knowledge.

You would need to know every possible consequence of the event. Every future outcome. Every person’s decisions. Every interaction across history. Every spiritual consequence. Every alternative world God could have created. Every eternal outcome.

Human beings don’t possess that perspective. This doesn’t mean every tragedy secretly has an obvious silver lining. It means our inability to identify God’s reason does not prove that no reason exists.

The book of Job makes this point powerfully. Job knows his suffering. God knows the entire reality. The difference in perspective is enormous.

Free Will and Moral Evil

One major Christian response to evil concerns human freedom. A huge amount of suffering comes from people doing things they ought not do. If God creates beings capable of genuine moral choices, those beings must be capable of choosing wrongly.

Otherwise, their “freedom” would be an illusion. Imagine God creates a person who is free to choose kindness or cruelty, but every time they choose cruelty, God rewrites their decision.

Did they genuinely have the ability to choose?

Not in any meaningful sense. A world containing free moral creatures includes the possibility of rebellion. Christianity says human beings actually did rebel.

“But God Could Have Created People Who Always Freely Choose Good”

Perhaps. But that claim is not as obvious as it sounds. If people are genuinely free, God may not be able to determine every free decision while simultaneously preserving that choice as genuinely undetermined human freedom.

This is not a limitation on divine power. Christian theology has never defined omnipotence as the ability to perform logical contradictions. God cannot create a square circle because “square circle” describes nothing coherent.

Likewise, “a person whose free choices are completely predetermined while remaining libertarianly free” may be incoherent. Different Christian traditions understand free will differently, but the basic apologetic point remains:

The existence of free moral agents gives a plausible explanation for why a good God might permit the possibility of moral evil.

But What About Natural Evil?

Free will explains murder better than earthquakes.

So what about cancer? Tornadoes? Birth defects? Disease?

Christianity’s answer extends beyond free will. Scripture teaches that creation itself is fallen. Romans 8 describes creation as subjected to corruption and groaning for restoration.

Christian theology therefore does not view the present natural world as the final, perfected state God intends. Death and decay characterize a creation awaiting redemption. Natural evil remains difficult. But once again, difficulty is different from contradiction.

The Problem of Evil Can Actually Create a Problem for Atheism

This point needs to be handled carefully. Christians should never respond to someone grieving by saying: “Actually, your suffering proves God.”

That would be insensitive. But in philosophical discussion, there is a legitimate question: What exactly do we mean when we call something objectively evil?

When someone says: “Children suffering is evil.”

Christians agree. But notice the claim.

They’re not merely saying: “I personally dislike children suffering.”

They’re usually saying: “It is genuinely wrong whether anyone approves of it or not.”

That sounds like an objective moral claim.

Where Does Objective Morality Come From?

If the universe is ultimately only matter, energy, physical laws, and accidental biological processes, where does objective moral obligation come from?

Evolution might explain why human beings developed cooperative behavior. Culture might explain why societies create moral rules. Personal preference might explain why individuals dislike suffering. But those explain why we feel certain ways.

They do not automatically explain why something is objectively morally wrong. There is a difference between: “Humans evolved to dislike murder.” and “Murder is morally wrong even if a society approves of it.”

Christianity grounds objective morality in God’s character. Goodness is not an arbitrary rule God invented. God Himself is the standard of goodness.

Does This Mean Atheists Can’t Be Moral?

Absolutely not. That would be a terrible argument. Atheists can be compassionate. Generous. Courageous. Self-sacrificing. Christians can behave terribly.

The question is not: “Can an atheist behave morally?” Clearly yes.,The question is “What provides the ultimate foundation for objective moral truths if there is no God?”

Those are very different questions. You do not need to believe in gravity for gravity to affect you. Likewise, a Christian can argue that people can recognize moral truths without believing in the God who grounds them.

“But I Can Ground Morality in Human Well-Being”

Some secular moral systems attempt exactly that. They argue that morality can be based on minimizing suffering or maximizing human flourishing. That can produce many moral conclusions Christians would affirm.

But another question appears: Why is human well-being objectively good?

Most of us strongly believe it is. But if humans are ultimately one accidental biological species among many, why does the universe impose a moral obligation to maximize our flourishing? You can choose human well-being as a foundation. But choosing it and demonstrating that it possesses objective moral authority are not the same thing.

Evil Makes More Sense if Goodness Is Real

You cannot have a crooked line unless there is some concept of straightness. Calling something evil assumes some standard by which reality ought to be different.,C.S. Lewis famously wrestled with this. He initially rejected God partly because the universe seemed cruel. But he later realized that calling the universe unjust raised another question: Where did his standard of justice come from?

If there is no objective standard, then suffering may be unpleasant. But calling it objectively wrong becomes harder to explain. The moral argument does not make suffering emotionally easier. It does show that evil is not necessarily evidence against God. In some ways, the reality of objective evil may fit better within a worldview containing objective moral truth.

“Couldn’t God Create a World With Less Suffering?”

Possibly. Christians do not need to claim this is the only logically possible world. But we should notice how little information we possess about alternative worlds.

Maybe changing one event changes thousands of later decisions. Maybe preventing one tragedy requires removing a particular freedom. Maybe certain virtues like courage, sacrifice, mercy, perseverance, are only possible in worlds where danger, pain, and loss exist.

This is sometimes called soul-making or character development. Scripture does teach that suffering can produce perseverance and mature faith.

James says: “The trying of your faith worketh patience.” — James 1:3 (KJV)

Romans says: “Tribulation worketh patience; And patience, experience; and experience, hope.” — Romans 5:3–4

That does not mean every instance of suffering exists merely to teach someone a lesson. But it demonstrates at least one possible good God can bring through suffering.

Certain Goods Require the Possibility of Suffering

Consider courage. Courage requires danger. Forgiveness requires wrongdoing. Mercy requires someone in need. Sacrificial love requires the possibility of genuine cost. Compassion becomes meaningful because suffering exists.

Again, this does not mean God creates every tragedy merely so someone else can develop character. It means a world without any possibility of suffering would also lack certain kinds of meaningful moral action.

Why Doesn’t God Reveal Every Reason?

Perhaps because we couldn’t understand every reason. A three-year-old cannot comprehend everything involved in complex surgery. The gap between an infinite God and human beings would be vastly greater.

Isaiah says: “For my thoughts are not your thoughts, neither are your ways my ways, saith the LORD.” — Isaiah 55:8 (KJV)

This verse should not be used as a lazy escape from every difficult question.,Christians should reason carefully.,But there is a legitimate point at which intellectual humility is appropriate. If God exists, we should expect His knowledge to exceed ours.

Christianity Does Not Merely Explain Evil.. It Promises to Defeat It

This is crucial. Some worldviews can describe suffering. Christianity claims evil is an intruder that will ultimately be judged. The cross deals with sin. The resurrection defeats death. Revelation points toward restoration.

The Christian answer is not: “Suffering isn’t actually that bad.”

The Christian answer is: “Suffering is so wrong that God intends to eliminate it.”

The Bible ends with death itself destroyed. That is a radically hopeful claim.

Christianity’s God Entered the Problem of Evil

This may be the most important apologetic point. Christianity does not merely offer an abstract deity who explains suffering from a distance. God entered human history as Jesus Christ.

Jesus experienced betrayal. Injustice. Humiliation. Torture. Execution. The cross means Christians worship a God who has experienced suffering. And if the resurrection happened, then God did not merely experience death.

He conquered it.

Does Evil Prove God Doesn’t Exist?

No.

The existence of suffering creates a serious emotional and philosophical challenge. But it does not create a logical contradiction between God’s goodness, God’s power, and God’s existence.

There are plausible reasons a good God might temporarily permit suffering. Human freedom explains much moral evil. A fallen creation provides a biblical framework for natural suffering. Human knowledge is too limited to conclude that God can have no morally sufficient reasons. And objective evil itself raises profound questions about the foundation of objective morality.

So the problem of evil remains difficult. But difficult is not the same as devastating to Christianity.

There Is Still a More Personal Question

Philosophy can answer: “Can God and suffering logically coexist?”

But philosophy cannot hug someone at a funeral. Eventually the question stops being: Why is suffering logically possible? and becomes Where is God when I am the one suffering?

That deserves its own answer.
