Why does God allow evil?

The question has a precise philosophical form and a precise theological answer. Both are worth knowing.

The logical problem of evil. Philosopher J.L. Mackie (1955) put it sharply: orthodox theism holds four claims — God is omniscient, omnipotent, omnibenevolent, and evil exists. Mackie argued these are logically incompatible. A God who knows about all evil, can prevent it, and is perfectly good would prevent it. Evil exists. Therefore (he argued) that God doesn't.

The free will defense. Alvin Plantinga's response is widely regarded as having defeated the logical version of the problem — Mackie himself conceded this in 1982. The core move: Mackie assumed an omnipotent God could create any logically possible world. Plantinga showed that's false. To create creatures capable of genuine moral good, God must create creatures capable of genuine moral evil; a being causally determined to always choose right is an automaton, not a free agent. A world with free creatures who sometimes choose evil is more valuable than a world with no free creatures at all. So the existence of evil does not contradict God's goodness or power.

This defeats the logical problem but not the evidential one — the question of why there is so much suffering, and so much that seems gratuitous. The free will defense is a shield, not a comfort. That's an honest distinction to keep.

Key biblical anchors:

• Romans 8:20-22 — creation "subjected to futility," "groaning" in the "bondage to decay," awaiting liberation. The brokenness is cosmic, not just moral.
• Genesis 3 — the Fall: moral disorder entering the world by human choice, with consequences rippling into the physical order ("thorns and thistles").
• Job — the canonical long-form treatment. Notably, God never gives Job the reason. He gives Job himself. The answer to suffering in Job is presence, not explanation.
• Psalms of lament (e.g. 22, 88) — the faithful asking the question loudly, without rebuke. Lament is a sanctioned form of faith.
• John 11:35 — "Jesus wept." God incarnate weeping at a graveside he is about to reverse. Both the grief and the power are real.

The major themes: 1. Moral evil is largely accounted for by free will — the price of a world capable of love. 2. Natural evil / suffering nobody chose is harder, and ties to the doctrine of a fallen, decaying creation. 3. The distinctively Christian move is not explanation but Incarnation — God entering the suffering rather than only ruling over it. 4. The unanswered remainder (the evidential problem) is held, not solved — and Scripture itself models holding it (Job, lament).

The deeper treatment runs through three frames: the thermodynamic/entropy debate, the comparative-religion contrast, and the Incarnational resolution.

Entropy and the Fall — a live intramural debate. Whether the Second Law of Thermodynamics is itself a consequence of the Fall is contested among orthodox thinkers, and the page should not pretend it's settled:

• The Morris/Williams position (mid-20th c. recent-creationism): the Second Law was absent from the "very good" creation (Genesis 1:31) and entered as a punitive consequence at the Fall (Genesis 3:17), explicitly equating Romans 8:20-22's "bondage of decay" with thermodynamic entropy. Morris later modified this to a pre-Fall "conservation of entropy" — a balanced state of 100% efficiency disrupted at the Fall.
• The Faulkner/Barnes counter-position: the Second Law was instituted during Creation Week as a functional good (citing Nehemiah 9:6, Colossians 1:16). Pre-Fall activities in the Genesis narrative require it — walking requires friction, eating requires metabolic breakdown, sunlight requires thermodynamic dissipation. On this reading Romans 8 describes the struggle with sin, not a retroactive rewrite of physics, and the Fall's physical effects are localized biological changes, not the invention of entropy.

The framework here leans toward entropy-as-created-good (it is more defensible scientifically and hermeneutically), while treating the "patch" language metaphorically rather than as a claim that physics was literally re-coded at the Fall. This matters for intellectual honesty: the cybertheology "entropy = Satan in a closed system" motif is a structural analogy, powerful as a lens, but it should not be overstated into a literal-physics claim the text doesn't require.

The comparative contrast. The distinctiveness of the Christian answer sharpens against the alternatives:

• Islam — preserves absolute divine sovereignty but, by rejecting Incarnation as shirk, keeps God eternally separate from the material decay. God manages suffering from outside; he does not enter it.
• Hinduism — treats the material world and its decay as maya (illusion); salvation is realizing the self's inherent divinity, escaping the cycle. Suffering is dissolved by re-description.
• Buddhism — dukkha (suffering) is intrinsic; the solution (Nirvana) is the extinction of desire and personhood. The self that suffers is itself the thing to be dissolved.
• Lurianic Kabbalah — the most structurally similar: shevirat ha-kelim (shattering of the vessels) explains cosmic brokenness, but tikkun olam places the entire repair on human shoulders; God is a passive beneficiary.

The Christian claim, against all of these, is that God neither denies the brokenness (Hinduism/Buddhism), nor stays outside it (Islam), nor delegates the repair to us (Kabbalah). He enters it himself and bears the cost personally. The Incarnation is the hinge.

The Incarnational "patch." Philosophically, the Incarnation functions as the point where the infinite, uncaused First Cause intersects the finite, decaying, closed system — to do from the inside what the system could not do for itself. Finite human action cannot reverse cosmic decay or overcome universal moral failure; the repair has to come top-down, from outside the closed system, by an agent willing to enter it. This is the structural core of the resurrection-as-reversal: not God removing suffering by decree, but God defeating it by passing through it.

The tension to hold honestly. This page resolves the logical problem (free will defense) and reframes the existential problem (Incarnation/presence). It does not resolve the evidential problem — the sheer quantity of apparently gratuitous suffering. That remainder is real. The pastorally and intellectually honest position is to hold it, as Job holds it: the answer given to suffering at the deepest level of Scripture is not a syllogism but a Person. Any version of this page that claims to have solved suffering has overreached and will ring false to someone actually in it.
