This is the hardest question skeptics ask - and it deserves a real answer. Not "just trust God." Not "it's a mystery." A genuine, thoughtful response that takes the pain seriously and still makes sense.
When someone asks this question, they're often not just being philosophical. They might have lost someone they loved. They might have been hurt deeply. They might be watching news of war, famine, or abuse and genuinely struggling.
The first thing a thoughtful Christian should do is not rush to an answer. Acknowledge that the question is real. The pain is real. And the question deserves more than a slogan.
With that said - there are actually very good reasons to believe that the existence of evil and suffering is compatible with a good, all-powerful God. Let's think through them carefully.
The two types need different responses. Most of the evil in human history is moral evil - caused by humans. The question then becomes: could God have made a world without moral evil?
For moral evil, the most powerful response is the Free Will Defense, developed by philosopher Alvin Plantinga.
The argument goes like this: love and goodness are only meaningful if they are freely chosen. A robot programmed to say "I love you" doesn't actually love anyone. God, wanting creatures capable of genuine love, goodness, and relationship, had to create beings with real free will.
But here's the problem with free will: if it's real, it can be used to choose evil as well as good. You cannot have a world where people genuinely love, serve, and choose God - and also guarantee that no one ever does anything wrong. The two are logically incompatible.
Philosopher Alvin Plantinga showed that the existence of evil does not logically contradict the existence of God. Even an all-powerful God cannot create beings with genuine free will and also guarantee those beings never choose evil. That's not a limitation of God's power - it's a logical impossibility, like making a square circle.
Natural evil is harder. Why would a good God allow earthquakes and childhood cancer? A few responses:
Here's something most people miss: the Problem of Evil actually assumes objective moral standards - which, as we learned in Lesson 2, point toward God.
When someone says "there is too much evil in the world for God to exist," they're assuming that some things are genuinely evil - not just unpleasant or unpopular. But objective evil requires an objective moral standard. And objective moral standards, as the Moral Argument shows, require God.
The very complaint against God - "this is truly evil" - smuggles in a premise that actually supports the existence of a moral lawgiver.
"God could have just made people with free will who always choose good."
Plantinga addresses this directly. A being "with free will that always chooses good" is a contradiction in terms - if it's guaranteed to always choose good, it doesn't truly have free will. True freedom means the genuine ability to choose otherwise. God could have created robots that always behave well - but that would not be the same as creating beings capable of real love and genuine goodness.
"The Holocaust was so extreme - no good purpose could justify it."
This is the most emotionally powerful form of the objection, and it deserves respect. A Christian should never minimize the Holocaust or claim to know exactly what God's purpose was. The honest answer is: we don't know why God permitted it specifically. But "I don't know why this happened" is different from "there is no God." Our inability to see a purpose doesn't mean no purpose exists - it may mean we don't have God's perspective. This calls for humility, not certainty in either direction.
Why can't God simply create beings with free will who always choose good?
The existence of evil does not disprove God. Moral evil flows from the free will that makes genuine love possible. Natural evil may serve purposes we can't fully see from our limited vantage point. And ironically, calling something "truly evil" already assumes an objective moral standard - which points back toward God.
