Stating the Problem Clearly

The problem of evil is often called the most powerful objection to belief in God. If God is all-powerful, all-knowing, and perfectly good, why does evil exist? Why do children suffer from cancer? Why do natural disasters kill thousands? Why does God allow genocide, torture, and abuse? Before we can respond to this challenge, we must understand it clearly. The problem of evil comes in several forms, and each requires careful analysis.

Why This Problem Matters

The problem of evil is not merely an intellectual puzzle for philosophers. It's a deeply personal struggle for many people—including Christians. When tragedy strikes, when suffering seems senseless, when evil appears to triumph, we all ask "Why?"

This question has driven some away from faith. The sheer weight of suffering in the world seems incompatible with a loving God. As philosopher David Hume famously asked: "Is God willing to prevent evil, but not able? Then he is impotent. Is he able, but not willing? Then he is malevolent. Is he both able and willing? Whence then is evil?"

Christians must take this problem seriously—not because it defeats our faith, but because it addresses the deepest questions of human existence. We serve a God who Himself entered into suffering. Our response to evil must be both intellectually honest and pastorally sensitive.

The Logical Problem of Evil

The logical problem of evil claims that the existence of God and the existence of evil are logically incompatible—that it's impossible for both to be true. The argument runs:

The argument claims that these premises are mutually exclusive—you cannot consistently hold all of them. Since evil obviously exists (Premise 7), and the divine attributes seem clearly defined (Premises 1-3), God must not exist.

Evaluating the Logical Problem

For this argument to work, the premises must be necessarily true—true in all possible worlds. But are they?

The critical premises are 4-6. Is it true that an omnipotent being could prevent any evil? That an omnibenevolent being would want to prevent all evil?

Not necessarily. Consider:

Against Premise 4: Omnipotence doesn't mean the ability to do the logically impossible. God cannot make a married bachelor or a square circle. If creating free creatures who always choose good is logically impossible, then even an omnipotent God couldn't do it. Evil might be the unavoidable byproduct of a greater good (free will) that even omnipotence cannot achieve without it.

Against Premise 6: A perfectly good being might permit evil for the sake of greater goods. A good parent permits the pain of vaccination for the child's health. A good God might permit suffering that produces compassion, courage, and spiritual growth. The assumption that a good God would prevent all evil is not obviously true—it depends on whether permitting some evil could serve greater purposes.

Philosopher Alvin Plantinga's "Free Will Defense" (which we'll examine in detail in the next lesson) has convinced most philosophers that the logical problem of evil fails. It's possible that God has morally sufficient reasons for permitting evil. This possibility is enough to defeat the claim of logical impossibility.

Today, few philosophers press the logical problem of evil. The consensus is that it doesn't succeed—the existence of God and evil are not logically incompatible.

The Evidential Problem of Evil

Since the logical problem has largely failed, most contemporary discussions focus on the evidential (or probabilistic) problem of evil. This argument doesn't claim that God and evil are logically incompatible but that evil makes God's existence unlikely.

This argument is more subtle. It doesn't claim that every evil must have a justifying reason—only that some evils appear to have no such reason. These are called "gratuitous" or "pointless" evils. Their existence, the argument claims, makes God's existence improbable.

The Challenge of Gratuitous Evil

The evidential problem gains force from specific cases that seem pointless:

A fawn trapped in a forest fire, suffering for days before dying—no human witnesses, no apparent purpose.

A child who dies of a painful disease after a short, suffering-filled life.

The Holocaust—six million Jews systematically murdered, including a million children.

These evils seem gratuitous—suffering without apparent redemptive purpose. If God exists and is good, why would He permit them?

Evaluating the Evidential Problem

The evidential argument depends on a crucial assumption: that we would be able to discern God's reasons for permitting evil if such reasons existed. But is this assumption warranted?

Consider the cognitive gap between humans and God. If God exists, His knowledge is infinite; ours is finite. His perspective is eternal; ours is temporal. He sees how all events connect across history; we see only fragments. Is it reasonable to expect that we could identify His reasons?

This response is called "skeptical theism." It doesn't claim to know God's reasons but questions whether we're in a position to judge that there are no reasons. The absence of a discernible purpose doesn't mean there is no purpose—it may mean the purpose is beyond our comprehension.

Analogy: A child may not understand why a parent allows painful medical treatment. The child experiences only pain and cannot grasp the larger purpose. But the parent's reasons are real, even if the child can't perceive them. Similarly, our inability to see God's purposes doesn't mean they don't exist.

The Emotional Problem of Evil

Beyond the intellectual arguments lies the emotional problem of evil—the visceral reaction to suffering that makes belief in God feel impossible. This is not a logical argument but a psychological barrier.

When someone loses a child, when disaster destroys a community, when evil seems to triumph unchecked—intellectual arguments can feel hollow. The sufferer doesn't want philosophy; they want God to show up, to explain, to make it stop.

The emotional problem requires a different response than the intellectual problem:

Presence over arguments. Job's friends started well—sitting with him in silence for seven days. They failed when they started explaining.

Lament over answers. The Psalms model honest complaint to God. "How long, O Lord?" is a prayer, not a heresy.

The cross over explanations. God's ultimate answer to suffering is not an explanation but a Person—the God who entered suffering, bore it, and conquered it.

Intellectual responses to evil are important but insufficient. They must be complemented by pastoral care, Christian community, and the presence of Christ with those who suffer.

Types of Evil

To respond effectively, we must distinguish different types of evil:

Moral Evil

Moral evil results from the free choices of moral agents—murder, theft, cruelty, oppression. Humans (and perhaps other free beings) are the immediate cause. The question here is why God permits free creatures to choose evil.

Natural Evil

Natural evil results from natural processes—earthquakes, diseases, floods, predation. No human choice directly causes them (though human choices may contribute). The question here is why God designed or permits a world with such features.

The Difference Matters

These types require different responses. Moral evil is addressed through the free will defense—God permits it because free will is valuable and cannot exist without the possibility of misuse. Natural evil is more challenging—what justifies earthquakes and cancer?

We'll address moral evil through the free will defense in the next lesson, and natural evil in the lesson following.

What Christians Must Affirm

Before developing responses, let's be clear about what Christians must affirm:

God is omnipotent. He has all power—there are no limits to what He can do except logical impossibilities and self-imposed constraints.

God is omniscient. He knows all things—past, present, future, and all possibilities.

God is perfectly good. He is holy, just, loving, and righteous. He never does wrong and always acts consistently with His perfect character.

Evil is real. It's not an illusion (contra Christian Science), not merely the absence of good (though it includes that), and not something to be embraced or ignored.

Evil is temporary. God will ultimately defeat evil, judge the wicked, and restore all things. The current situation is not the final word.

Any response to the problem of evil must maintain these commitments. We cannot solve the problem by diminishing God's power, knowledge, or goodness, or by denying the reality of evil.

The Christian Advantage

Before feeling defensive about the problem of evil, Christians should recognize that we have resources other worldviews lack:

We can call evil "evil." On naturalism, evil is just stuff we don't like—there's no objective standard. Christianity grounds real evil in deviation from God's character and will.

We have a framework. The biblical narrative—creation, fall, redemption, restoration—provides context for understanding evil's origin, presence, and ultimate defeat.

We have a suffering God. In Christ, God entered suffering, experienced it from within, and conquered it. We don't worship a distant deity but an Emmanuel—God with us in our pain.

We have hope. Evil will not have the last word. God will judge, restore, and renew. Suffering is real but temporary; glory is coming.

The problem of evil is a problem for everyone—but Christianity has more resources for addressing it than any other worldview.

Conclusion: Approaching the Problem Rightly

The problem of evil is real and serious. Christians should not dismiss it, minimize it, or pretend we have easy answers. Suffering is terrible, evil is monstrous, and honest people struggle to reconcile them with a good God.

But the problem is not unanswerable. The logical problem fails—God and evil are not logically incompatible. The evidential problem depends on assumptions we have reason to question—our ability to discern divine purposes. And the emotional problem, while real, calls for pastoral care alongside intellectual response.

In the following lessons, we'll develop specific responses: the free will defense for moral evil, the fall and cosmic redemption for natural evil, and the greater-good theodicy for the purpose of suffering. Each contributes to a cumulative case that Christian theism can account for evil while maintaining God's perfect character.

The problem of evil is not a reason to abandon faith but an invitation to deeper faith—faith that trusts God even when we don't understand, that holds onto His goodness even in darkness, and that hopes for the day when every tear will be wiped away and evil will be no more.
