Why Does God Allow Evil to Exist? A Three-Faith Comparison

Jewish theology has wrestled with the problem of evil — called theodicy — for millennia. The Hebrew Bible doesn't shy away from the reality of evil's presence in the world. As Genesis 6:5 records, God himself observed that "the wickedness of man was great in the earth" Genesis 6:5, acknowledging evil as a genuine feature of human existence rooted in the human heart. This isn't a failure of divine power but a recognition of human moral freedom.

A cornerstone of Jewish theodicy is the idea that God can redirect evil toward good ends. The story of Joseph is the paradigmatic example: his brothers intended harm, yet God transformed that harm into salvation Genesis 50:20. This doesn't excuse evil, but it insists that God's sovereignty operates even through it. Rabbinic thinkers like Maimonides (12th century) argued that most evil is self-inflicted through bad choices, echoing Proverbs: "Do they not err that devise evil?" Proverbs 14:22.

Jewish thought also holds that evil sometimes functions as divine discipline or consequence for communal sin. Daniel 9:14 frames national suffering as a righteous response from God to disobedience Daniel 9:14. This isn't a comfortable answer, but it insists on God's moral coherence. Proverbs 12:21 offers a counterbalancing promise: "There shall no evil happen to the just" Proverbs 12:21, suggesting that ultimate justice, even if delayed, is guaranteed.

Christian theology approaches the question of why God allows evil through several interlocking frameworks: the Fall of humanity, free will, and eschatological redemption. The tradition broadly holds that evil entered the world through human disobedience — a position rooted in Genesis — and that God's allowance of evil is inseparable from his gift of genuine moral freedom. God saw the depth of human wickedness Genesis 6:5, yet chose not to override human agency entirely.

The most influential Christian response to evil is the "soul-making" theodicy associated with Irenaeus (2nd century) and later developed by John Hick in the 20th century, which argues that moral and natural evil are necessary conditions for spiritual growth and character formation. Alongside this sits Augustine's privation theory — evil isn't a created thing but an absence of good. The Joseph narrative, cited across traditions, resonates deeply in Christian thought: God works through evil toward redemptive ends Genesis 50:20.

Christians also emphasize that God doesn't remain distant from suffering — the Incarnation and crucifixion place God squarely within human pain. Evil may be permitted, but it's not endorsed. Proverbs 14:19 promises an ultimate moral order: "The evil bow before the good" Proverbs 14:19, a verse Christians read as pointing toward final judgment and restoration. The tension between present suffering and future justice is held together by hope in resurrection.

Islamic theology addresses the existence of evil primarily through the concept of ibtila' — divine testing. The Quran states repeatedly that God tests human beings with hardship, fear, and loss to distinguish the faithful from the heedless. Evil, in this framework, isn't a flaw in God's creation but a deliberate feature of a morally serious universe. Human wickedness, as the Hebrew tradition also notes, originates in the human heart and its choices Genesis 6:5, a view shared across the Abrahamic spectrum.

Islamic scholars distinguish between sharr (evil/harm) that is moral — arising from human sin and free will — and that which appears evil but serves a hidden divine wisdom. The 13th-century scholar Ibn Qayyim al-Jawziyyah argued extensively that nothing God permits is without purpose, and that apparent evil often contains embedded mercy or correction. This resonates with the Quranic principle that God does not wrong anyone — a parallel to the biblical insistence that "the LORD our God is righteous in all his works" Daniel 9:14.

Islam also teaches that evil has a limited, bounded existence — it cannot ultimately triumph. The wicked face consequences, and mercy and truth belong to those who pursue good Proverbs 14:22. Suffering in this life is viewed as temporary and potentially purifying, with the scales of divine justice fully balanced only in the afterlife. The Quran's theodicy is thus deeply eschatological: the full answer to why evil exists won't be visible until the Day of Judgment.
