10th Grade Bible & Scripture — Christian Apologetics — Defending the Faith
If God Is Good, Why Does Evil Exist?
The problem of evil is the most common and emotionally powerful objection to Christianity. It can be stated simply: If God is all-powerful, He could prevent evil. If God is all-good, He would want to prevent evil. But evil exists. Therefore, either God is not all-powerful, not all-good, or does not exist.
This objection has been raised by skeptics for centuries, and it deserves a serious, thoughtful response. The Christian faith does not ignore suffering — it confronts it directly. The cross of Christ stands at the center of Christianity as proof that God takes evil and suffering with absolute seriousness.
Philosopher Alvin Plantinga demonstrated that the logical problem of evil — the claim that God and evil are logically incompatible — has been conclusively answered. The argument assumes that an all-powerful, all-good God would have no morally sufficient reason for permitting evil. But this assumption is unwarranted.
God may have morally sufficient reasons for permitting evil that we cannot fully comprehend. A parent who allows a child to receive a painful vaccination is not being cruel — the pain serves a greater good. Similarly, God may permit suffering for purposes that serve His ultimate plan for creation, even when we cannot see those purposes from our limited perspective.
The free will defense argues that God created human beings with genuine freedom of choice. Freedom makes love, virtue, and meaningful relationship possible — but it also makes sin and evil possible. A world of free creatures who can choose good must also be a world where they can choose evil. God could have created robots who never sin, but they could never genuinely love.
Augustine of Hippo made a crucial insight: evil is not a 'thing' in itself but a privation (absence) of good, just as darkness is not a substance but the absence of light, and cold is not a force but the absence of heat. God created all things good (Genesis 1:31). Evil entered the world not through God's creation but through the misuse of created free will.
This understanding answers the question 'Did God create evil?' No — God created good beings with genuine freedom, and those beings chose to rebel. Evil is the corruption of something God made good, not an independent creation. Satan was created as a good angel who freely chose rebellion. Adam and Eve were created good and freely chose disobedience.
This does not minimize the reality of evil — evil is terribly real in its effects. But it shows that evil is parasitic on good. It cannot exist without something good to corrupt. Evil is always a departure from God's design, never an expression of it.
The Bible teaches that God can bring good out of suffering. Joseph's brothers sold him into slavery, but God used that evil to save thousands from famine (Genesis 50:20). The crucifixion of Jesus — the greatest evil in human history — became the means of salvation for all who believe.
Paul teaches that suffering produces perseverance, character, and hope (Romans 5:3-5). James says that trials produce mature faith (James 1:2-4). This does not mean suffering is good in itself, but that God, in His sovereignty, can redeem even the worst suffering for His purposes.
The book of Job addresses suffering most directly. Job was righteous, yet he suffered enormously. God never explains to Job why he suffered. Instead, God reveals Himself — His power, wisdom, and sovereign control over all creation. Job's response is not philosophical understanding but personal trust: 'My ears had heard of you but now my eyes have seen you' (Job 42:5).
Ultimately, Christianity's answer to the problem of evil is not a philosophical argument but a historical event: the cross of Jesus Christ. In the cross, God did not remain distant from human suffering — He entered into it. The Creator of the universe endured the worst that evil could inflict: betrayal, injustice, torture, and death.
The cross shows that God takes evil with ultimate seriousness. He did not wave a hand and dismiss it — He bore its full weight in His own body. And the Resurrection shows that evil does not have the last word. Death itself has been defeated, and a new creation is coming where 'there will be no more death or mourning or crying or pain' (Revelation 21:4).
The atheist who uses evil to argue against God must explain where the standard of 'good' comes from in a godless universe. If there is no God, there is no objective good, and therefore no objective evil. The very fact that we recognize evil as evil points to a moral standard — and therefore to a moral God who will ultimately set all things right.
Write thoughtful responses to the following questions. Use evidence from the lesson text, Scripture references, and primary sources to support your answers.
Explain the free will defense in your own words. Why is genuine freedom necessary for love and virtue, and why does it necessarily include the possibility of evil?
Guidance: Consider the difference between a robot programmed to say 'I love you' and a person who freely chooses to love. Why is forced goodness not truly good?
How does the cross of Christ serve as God's ultimate answer to the problem of evil? Why is this more powerful than any philosophical argument?
Guidance: Think about how the cross shows that God is not distant from suffering but entered into it, and how the Resurrection demonstrates that evil does not have the final word.
Why does the atheist's argument from evil actually undermine atheism? How does the recognition of genuine evil point to the existence of God?
Guidance: Consider C.S. Lewis's insight that you cannot call a line crooked unless you have some idea of a straight line. Without God, there is no objective standard of good by which to judge anything as evil.
