Whenever theists are pressed on why God permits devastating moral evils—genocides, child abuse, and war—their primary defense is almost always the Free Will Defense. Alvin Plantinga and other Christian philosophers argue that genuine libertarian free will is an immense good, but that it is logically impossible for God to grant creatures free will without risking that some of them will choose to do evil.
I want to examine this defense by bringing up an argument frequently discussed on debate forums: the Problem of Heaven. When you look closely at standard theistic doctrine about the afterlife, the Free Will Defense falls into a direct logical contradiction.
The Dilemma of the Afterlife
In mainstream Christian and theistic theology, Heaven is described as a state of eternal, unbroken fellowship with God where there is no sin, no suffering, and no evil (Revelation 21:4: "He will wipe away every tear... there will be no more death or mourning or crying or pain").
This immediately forces a fatal dilemma regarding free will:
Horn 1: Do people in Heaven have free will?
If the answer is yes—if redeemed human beings in Heaven retain their free will, yet never commit evil or cause suffering—then Plantinga's core claim is false! It is entirely possible for God to create a world where creatures have free will and yet never commit evil. If God could do it in Heaven for eternity, why couldn't an omnipotent God have done that from the very beginning on Earth? Why put humanity through thousands of years of horrific slaughter, rape, and agony just to get to a state that could have been actualized on day one?
Horn 2: Do people in Heaven lack free will?
If the answer is no—if free will is stripped away or suppressed in Heaven so that humans are incapable of sinning—then the theist admits that free will is not an essential requirement for the highest state of human existence. If God is willing to dispense with free will in Heaven to ensure perfect peace and safety, then an all-loving God would have been morally obligated to do so on Earth to spare millions of innocent victims from historical atrocities.
The Failure of the "Soul-Making" Dodge
The common reply is that Earth is a "filtering phase" or a school where we freely choose alignment with God before being locked into perfection. But this fails on multiple fronts.
First, what about the billions of human beings who never participated in this "school"—such as miscarried embryos, stillborn babies, and infants who died of infectious disease before developing moral comprehension? Traditional theism typically holds that these souls go straight to Heaven. If they can enjoy eternal bliss and sinless freedom in Heaven without needing a lifetime of earthly suffering, then the earthly gauntlet was never necessary in the first place.
Second, if God possesses middle knowledge (Molinism) or omnipotence, God could have simply created those souls who He knew would freely choose the good in all circumstances. The fact that the universe contains massive gratuitous evil proves that the traditional theistic narrative is structurally inconsistent. Theism is far more likely a human myth than a reality.
The "Problem of Heaven" is a classic puzzle on Reddit debate forums, and it certainly sounds like an airtight dilemma at first glance: either Heaven has free will (meaning Earthly evil was unnecessary), or it doesn't (meaning free will isn't that important). But this argument misunderstands both the philosophical nature of human freedom and the theological doctrine of sanctification.
The Difference Between Initial Choice and Habitual Character
The dilemma assumes that "having free will" must always mean standing in a permanent state of 50/50 moral indecision, like a coin hovering in mid-air. But that is not how freedom works in human psychology or metaphysics.
When you learn to play the piano or master a discipline, you initially struggle, make mistakes, and freely choose between hitting the right or wrong notes. Over decades of practice, your character and muscle memory become so aligned with music that playing beautiful melodies becomes second nature. A loving mother does not stand in agonizing indecision about whether to drown her infant in the bathtub; her moral character is so thoroughly established that while she has the physical capacity to do it, she is psychologically and morally confirmed in love.
That is what Heaven is: the final, freely chosen culmination of a soul’s journey. Earth is the environment where free creatures decide whether they want to surrender their ego and love God, or live in self-absorbed rebellion. By the time a soul enters the unmediated presence of God in Heaven (the Beatific Vision), their character has been so completely confirmed in love that they freely choose the good with joyful certainty. God does not force them; they have become the kinds of people who no longer want to sin.
Why God Couldn't Just "Start With Heaven"
The skeptic asks: why couldn't God just instantiate everyone in that confirmed state from the beginning? Because authentic, mature love cannot be pre-programmed like code in a robot.
If God created humans with a psychological inability to choose anything other than God from second one, that would not be genuine relational love; it would be deterministic coercion. A forced declaration of love is meaningless. True virtue requires having had the genuine alternative to choose otherwise and choosing to align with the good.
As for infants and those who die young, Christian theology recognizes that God extends grace to them, but their state does not invalidate the profound intrinsic value of free creatures who walked through the crucible of life, overcame hardship, and freely forged a deep, resilient faith. Heaven is not a contradiction of free will; it is the ultimate fulfillment of free will reaching its true home.
