Why Does God Allow Evil? A Comparative Look at Judaism, Christianity, and Islam

Jewish thought on theodicy is ancient, contested, and remarkably honest about the tension. The Hebrew Bible doesn't shy away from the problem — it confronts it head-on in texts ranging from Job to the Psalms of lament. Several distinct threads emerge from the tradition.

One prominent strand ties evil to human moral failure and divine response. Daniel 9:14 frames the suffering of Israel not as divine cruelty but as a just consequence of disobedience: "the LORD watched upon the evil, and brought it upon us... for we obeyed not his voice" Daniel 9:14. This covenantal logic — that evil enters as a consequence of broken relationship with God — runs deep in prophetic literature. Ezekiel echoes this when God declares, "it was not without cause that I, GOD, resolved to bring this evil upon them" Ezekiel 6:10, implying moral coherence even in catastrophe.

A second strand, perhaps more theologically sophisticated, is the idea that God can redirect human evil toward good ends. Genesis 50:20 — Joseph's famous declaration to his brothers — captures this beautifully: "ye thought evil against me; but God meant it unto good" Genesis 50:20. Medieval philosopher Maimonides (12th century) built on this in his Guide for the Perplexed, arguing that most evil is either self-inflicted or the result of human choices, not divine design.

A third strand, reflected in Proverbs, insists on a moral order: "Do they not err that devise evil?" Proverbs 14:22, suggesting that evil ultimately undermines itself. Yet Jewish tradition — especially post-Holocaust theology, as articulated by thinkers like Elie Wiesel and Rabbi Irving Greenberg — refuses easy answers. The tradition permits, even encourages, arguing with God over the problem of evil.

Proverbs 16:4 adds a harder edge: "GOD made everything for a purpose, even the wicked for an evil day" Proverbs 16:4, implying divine sovereignty extends even over wickedness — a claim that generates ongoing rabbinic debate.

Christian theodicy inherits the Hebrew Bible's framework but reframes it decisively through the cross. The central Christian claim is that God didn't just permit evil from a distance — he entered into it. That conviction shapes everything.

The Old Testament passages remain authoritative for Christians. Daniel 9:14's acknowledgment that God "watched upon the evil" and brought it as a just consequence of disobedience Daniel 9:14 is read as consistent with God's righteous character. Genesis 50:20's Joseph narrative Genesis 50:20 is frequently cited by Christian theologians — Augustine (4th–5th century), John Calvin (16th century), and C.S. Lewis in the 20th century all appealed to the idea that God can bring good out of human evil without being the author of it.

The dominant Christian response to theodicy, however, is the free will defense, most rigorously articulated by Alvin Plantinga in his 1974 work God, Freedom, and Evil. God allows evil, on this view, because genuine love requires genuine freedom, and genuine freedom makes moral evil possible. God values a world with free creatures capable of love over a world of moral robots.

A second distinctly Christian answer is soul-making theodicy, associated with Irenaeus (2nd century) and developed by John Hick in the 20th century: evil and suffering are the necessary conditions for spiritual growth, courage, compassion, and Christlike character. Suffering isn't pointless — it's formative.

Genesis 6:5's bleak observation that human wickedness was pervasive Genesis 6:5 is read by Christian theologians as the backdrop for both the flood narrative and, ultimately, the need for redemption. Evil, in Christian thought, isn't just a philosophical puzzle — it's a diagnosis that requires a cure, which Christianity locates in Christ.

Disagreement exists, of course. Open theists like Greg Boyd argue God genuinely grieves evil and didn't foreordain it. Calvinist theologians like R.C. Sproul contend God ordains all things, including evil, for his glory — a position that echoes Proverbs 16:4 Proverbs 16:4 but strikes many as morally troubling.

Islamic theodicy is grounded in two unshakeable convictions: God's absolute sovereignty (qadar) and God's absolute justice (adl). These aren't in tension for mainstream Islamic theology — they're complementary. Evil exists, but God is never unjust.

Surah Al-Falaq (113:2) acknowledges the reality of evil within creation directly: "From the evil of that which He created" Quran 113:2, and Muslims are instructed to seek refuge in God from it. This is a striking admission — evil is real, it exists within the created order, and the appropriate response is turning to God rather than philosophical speculation alone.

The Qur'an's most direct theodicy statement may be Surah Fussilat 41:46: "Whoever does righteousness — it is for his [own] soul; and whoever does evil [does so] against it. And your Lord is not ever unjust to [His] servants." Quran 41:46 This verse does several things at once: it locates moral evil in human agency, insists on personal accountability, and emphatically clears God of injustice. The Arabic phrase wa ma rabbuka bi-zallamin lil-'abid — "your Lord is not unjust to servants" — is considered one of the Qur'an's clearest theodicy statements by scholars like Ibn Kathir (14th century).

Classical Islamic theology, particularly the Ash'ari school (founded by Abu al-Hasan al-Ash'ari, 10th century), holds that God creates all things including evil acts, but humans acquire (kasb) moral responsibility for their choices. The Mu'tazilite school, by contrast, argued God cannot create evil — a position that was largely rejected by Sunni orthodoxy but reflects the genuine diversity of Islamic thought on this question.

Islamic tradition also emphasizes that apparent evil — illness, loss, hardship — may carry hidden mercy or serve as expiation for sins. The Prophet Muhammad's hadith literature is rich with this theme, though those passages aren't in the retrieved set and can't be cited here. What the Qur'an makes clear is that God's justice is never in doubt, even when human understanding falls short Quran 41:46.

Tanakh passages state that God allows and even brings calamity as just response to disobedience, asserting divine righteousness in all works (Daniel 9:14; Ezekiel 6:10). Daniel 9:14 [[cite:9]

Human evil is real and pervasive, which frames why such judgment occurs (Genesis 6:5). Genesis 6:5

Yet God can turn what humans intend as evil toward life-preserving good, showing purposeful governance without endorsing the evil itself (Genesis 50:20). Genesis 50:20

Proverbs teaches that God made everything for a purpose, including the wicked for a day of calamity, and commends mercy and truth as the path opposed to devising evil (Proverbs 16:4; Proverbs 14:22). Proverbs 16:4 Proverbs 14:22

Christians receive the Old Testament witness that God, being righteous, may allow or bring judgment, not arbitrarily but “not without cause,” while remaining just in all His works (Daniel 9:14; Ezekiel 6:10). Daniel 9:14 Ezekiel 6:10

Scripture affirms the depth of human wickedness and responsibility for evil (Genesis 6:5; Proverbs 14:22). Genesis 6:5 Proverbs 14:22

Yet God’s providence can reframe intended evil into saving outcomes, as in Joseph’s words, “you meant evil… but God meant it for good,” highlighting that evil is neither ultimate nor outside God’s redemptive intent (Genesis 50:20). Genesis 50:20

The Qur’an teaches that people seek God’s protection from the evil within creation, acknowledging its reality without ascribing injustice to God (Q 113:2). Quran 113:2

Each person’s deeds return to the self; righteousness benefits the doer and evil harms the doer, for the Lord is never unjust to servants (Q 41:46). Quran 41:46
