The deep dive explains the argument. This track makes you able to wield it — rebuild it from memory, meet its hardest objections, and handle the hardest topic with care.
Let us be honest at the outset: suffering is the hardest objection to belief in God, and it deserves to be felt, not explained away. The reality of cancer wards, genocide, and the loss of a child is a genuine mystery, and no tidy theodicy can fully account for it. This argument does not pretend otherwise, and it is no substitute for grief or for sitting with someone in pain.
It makes one narrow, careful observation. When we call some things truly evil — not merely unpleasant, not merely things we dislike, but genuinely wrong, such as torturing a child for amusement — we are appealing to a real standard of good that the world has fallen short of. C.S. Lewis put it from his own atheist days: his case against God was that the universe seemed cruel and unjust. But where had he gotten the idea of just and unjust? A line is only crooked by comparison with a straight one. The very outrage that fuels the problem of evil presupposes an objective good, and an objective standard of good is itself hard to ground without God.
So this does not "solve" suffering or lessen its weight. It observes that the deep moral intuition driving the objection points, on reflection, back toward the existence of the very God it was raised against — turning the problem into unexpected evidence. Note the scope: this argument reaches a standard of good that only God can ground — not yet the Father, Son and Holy Spirit. Identifying that being with the God revealed in Christ is the work of the other arguments and of revelation.

Not more prose — the load-bearing structure. See the skeleton, then learn to defend each bone.
We recognise certain things as objectively, genuinely evil — not merely things we dislike.
Objective evil presupposes an objective standard of good that things fall short of.
An objective standard of good requires God — so the recognition of evil points to God.
This is the moral argument applied to the problem of evil — a narrow, careful point. It is not a pastoral answer to suffering, and it does not dismiss the force of the problem of evil. It observes only that calling something truly evil assumes a standard of good that is hard to ground without God.
Then the conceptual step — what does evil presuppose?Evil is a departure from how things ought to be — a corruption of a good. That presupposes a real standard of good and a way things are supposed to be. A purely indifferent universe has no ought, so it can host only events we dislike, not genuine evil.
Our outrage points past us
Our response to the Holocaust, to torture, to cruelty presents itself as a response to something really wrong, not merely disliked. If evil were mere preference, moral protest would be incoherent.
Even the skeptic insists on it
The reality of evil is one of the things atheists most strongly affirm — but that very insistence assumes an objective wrong, not a matter of taste.
Evil is a privation
Evil is a corruption or lack of a good that ought to be whole. That presupposes a real standard of good and a way things are supposed to be — a design, a purpose.
Indifferent matter has no ought
A purely physical, indifferent universe has no way things are supposed to be, so it can host no genuine evil — only events we happen to dislike. The standard evil falls short of is grounded in God.
Handle this gently — it touches real pain. Each objection in its strongest form first, then the reply.
The one that matters most: Rowe’s evidential problem — not a contradiction, but gratuitous suffering as evidence. The deep dive answers it at length — take it with you, not just the replies below.
Strongest form
A good, all-powerful God would not allow gratuitous suffering. The existence of evil is strong evidence against God.
Reply
This is the serious challenge, and it deserves full engagement — the classical responses — free will, soul-making, and Plantinga’s free-will defence, which shows only that there is no logical contradiction, not that we know God’s reasons. (Christians differ on how free will works, and this site does not adjudicate that.) To call suffering genuinely evil, not just unpleasant, you must assume an objective standard of good, which is hard to ground without God. So evil is a genuine intellectual difficulty for faith — the evidential version is unresolved, and honesty requires saying so. The narrower point here is separate: calling suffering genuinely evil is itself hard to ground without God.
Strongest form
Define evil naturally as harm or suffering. No transcendent standard is required.
Reply
Harm and suffering are descriptive; calling them evil — something that ought not to be, that demands a response — is normative. Why should a configuration of matter that causes pain be wrong? Naturalism can describe suffering but cannot ground the ought-not-ness that makes it evil rather than merely unpleasant.
Strongest form
Our sense of evil is an evolved reaction to things that harmed our ancestors — nothing more.
Reply
That explains the feeling of revulsion, not the fact that genocide is truly wrong. If evil is just an aversion, the torturer is not mistaken, only differently wired — which no one believes about real atrocities. Debunking the feeling does not touch the objective wrongness we actually affirm.
Strongest form
Turning evil into an argument for God sidesteps the real pain and the real challenge.
Reply
A fair caution — and this argument is not a pastoral answer to suffering, nor does it dismiss the force of the problem of evil. It is a narrower logical point: the reality of objective evil sits uneasily in a godless universe. Both can be true at once — evil is a hard problem for faith, and the reality of evil is a hard problem for atheism.
Strongest form
Bite the bullet — deny objective evil entirely. It is all just preference.
Reply
That is at least consistent, but almost no one can live it. The person who says nothing is really evil still protests their own betrayal, still calls out injustice done to them. And it concedes the point: to keep objective evil you need the standard that comes with God. You can drop evil or keep God — dropping evil is a steep price.
Strongest form
Calling evil a lack or privation rather than a real thing is a dodge.
Reply
The privation view (Augustine) does not deny evil’s reality or horror — a privation can be devastating, as blindness is a real lack of sight. It is a metaphysical claim that evil is parasitic on good, a corruption of something that ought to be whole. That presupposes the ought-to-be, the standard — which is the argument’s point.
Strongest form
Grant the logical point entirely — William Rowe, a leading atheist critic, granted it himself: Plantinga showed God and evil are not formally contradictory. That was never the real objection. Rowe’s is evidential. Picture a fawn trapped in a distant forest fire, badly burned, lying in agony for days before it dies — suffering no human will ever know about, serving no purpose anyone can name. Cases like that exist in enormous numbers. It is not that they are impossible on theism; it is that they are far more probable on atheism. This is the version that carries the weight, and it is the one you will actually be asked about.
Reply
Concede first, because this is a real weight on faith and pretending otherwise is worse than useless. The classical reply is Stephen Wykstra’s, and it is narrow. His principle — CORNEA — says you may move from “I see no justifying reason” to “there probably is none” only if you would expect to see the reason if there were one. Between an infinite mind and ours that expectation is hard to defend: a toddler who cannot see why the injection is necessary has not thereby found evidence that it isn’t. But be honest about the cost — that reply buys agnosticism about God’s reasons, not an account of them, and pressed too far it would undercut our confidence about God’s goodness as well. The honest verdict is the one the deep dive reaches: the evidential problem remains live and unresolved by either side. There is no consensus that gratuitous evil disproves God, and none that it has been explained away. What Christianity offers here is not a solution but a person — a God who entered the suffering rather than accounting for it.
Knowledge you can't retrieve under pressure isn't yours yet. Three drills that route this argument through tools you already have.
Reconstruct the argument from memory: that we recognise objective evil (P1), that this presupposes a standard of good (P2), and that the standard points to God — while being clear this is not a pastoral answer to suffering.
Five cards on objective evil, how this relates to the usual problem of evil, and evil as privation.

"That is the hardest question anyone can ask, and I do not want to wave it away — the suffering of children is a genuine weight on faith, and honest believers feel it. But let me gently point at something underneath your objection. You called that suffering evil — not just unfortunate, not just something you happen to dislike, but truly wrong, something that ought not to be. Where does that ought-not come from? If the universe is only matter and energy with no purpose, then a child suffering is no more wrong than a rock rolling downhill — it just is. The very outrage that fuels your objection assumes a real standard of good that the world is failing to meet, and that standard is exactly what is hard to have without God. So evil is a real problem for my faith — I will not pretend otherwise — but the reality of evil is an even harder problem for a godless universe. You may have to give up God, or give up calling anything truly evil. I do not think you actually want to give up the second."
