What Does Each Tradition's Scripture Say About the Limits of Human Knowledge of God?

The Hebrew scriptures are remarkably candid about the gap between human cognition and divine knowledge. The Book of Job, one of the tradition's most philosophically probing texts, poses a sharp rhetorical challenge: can God even be instructed? Job 21:22 The implied answer is no — God's vantage point is simply incommensurable with human understanding.

Zophar the Naamathite, speaking in Job 11, goes further, framing divine mystery as something that actively resists human investigation Job 11:7. The Hebrew word ḥēqer (limit, searching-out) suggests that the Almighty has a depth that no human probe can reach. This isn't agnosticism — it's a form of reverent epistemology.

Psalm 73 records a more cynical voice, one that questions whether God knows anything at all Psalms 73:11. The psalmist Asaph attributes this doubt to the wicked, implicitly rebuking it — but the fact that the doubt is voiced at all shows the tradition was willing to wrestle openly with questions about divine knowledge. Scholars like Jon Levenson (Harvard Divinity School) have noted that Job and the Psalms together create a 'dialectical theology' in which human limitation is not a scandal but a theological given.

Christianity inherits the Hebrew scriptural tradition wholesale, meaning texts like Job 11:7 and Psalm 73 remain canonical for Christian readers Job 11:7 Psalms 73:11. The Old Testament's insistence that God's knowledge vastly exceeds human comprehension carries directly into Christian theology. Job's rhetorical question — can God be instructed in knowledge? — is treated by patristic writers like Gregory the Great (c. 540–604 CE) as a foundational statement of divine transcendence.

The Psalm 73 passage, where skeptics ask 'How doth God know?' Psalms 73:11, is read in Christian exegesis as a warning against presuming to fully comprehend divine omniscience. Augustine of Hippo (354–430 CE) argued in his Confessions that God knows all things in a single eternal act, a mode of knowing utterly unlike sequential human cognition — making the gap between divine and human knowledge not merely quantitative but qualitative.

It's worth noting that the New Testament adds its own layer, particularly Paul's statement in 1 Corinthians 13:12 that 'now we see through a glass, darkly' — though that passage isn't in the retrieved sources, so I won't cite it directly. What the retrieved Hebrew texts confirm is that Christianity's epistemological humility before God has deep scriptural roots Job 21:22.

The Quran addresses the limits of human knowledge of God with striking directness. Surah Ta-Ha (20:110) states plainly that while God knows everything — past, present, and future — human beings simply cannot encompass that knowledge Quran 20:110. The Arabic verb yuḥīṭūna (to encompass, to surround) is significant: it's not just that humans know less than God, it's that God's knowledge forms a totality that human minds cannot even wrap around.

Surah Al-Baqarah (2:32) reinforces this with a scene from the angels themselves, who confess: 'we have no knowledge except what You have taught us' Quran 2:32. If even the angels are epistemically dependent on divine revelation, the implication for humans is clear — all genuine knowledge of God is gift, not achievement. This aligns with classical Islamic theology (kalām), where scholars like al-Ghazālī (1058–1111 CE) argued that God's essence (dhāt) is fundamentally unknowable; only His attributes (ṣifāt) as revealed in scripture are accessible.

Surah Ar-Ra'd (13:19) draws a moral contrast between those who recognize revealed truth and those who are spiritually 'blind' to it Quran 13:19, suggesting that even the limited knowledge of God available to humans requires a kind of divinely-granted discernment. There's genuine scholarly disagreement here: Mu'tazilite theologians historically argued that human reason could arrive at some knowledge of God independently, while Ash'arite thinkers insisted revelation was indispensable. The Quranic texts cited lean toward the Ash'arite position.

Hebrew Bible texts highlight sharp limits on human knowing: the Psalmist records the skeptical taunt, “How could God know? Is there knowledge with the Most High?”—a question that exposes human presumption before divine knowledge Psalms 73:11.

Job rebukes the idea that humans can teach God, asking, “Can God be instructed in knowledge, The One who judges from such heights?” which places God’s perspective beyond ours Job 21:22.

Another voice in Job presses the point as an open question that implies a boundary: “Would you discover the mystery of God? Would you discover the limit of the Almighty?”—suggesting God’s essence and scope aren’t fully searchable by human inquiry Job 11:7.

Because the Hebrew Bible is part of Christian Scripture, Christians also receive Job’s insistence that God cannot be tutored by human beings—“Can God be instructed in knowledge, The One who judges from such heights?”—as a boundary marker for theology Job 21:22.

Likewise, the probing question “Would you discover the mystery of God? Would you discover the limit of the Almighty?” is taken to mean that while God may be known truly, God isn’t known exhaustively by finite minds Job 11:7.

And the Psalm’s challenge—“How could God know? Is there knowledge with the Most High?”—frames human doubt and irony against divine omniscience, reinforcing the Creator–creature gap that limits comprehension Psalms 73:11.

The Qur’an teaches that God’s knowledge is total while human grasp is partial: “He knows what is [presently] before them and what will be after them, but they do not encompass it in knowledge,” marking a firm limit on human comprehension Quran 20:110.

Angels themselves confess epistemic humility—“Exalted are You; we have no knowledge except what You have taught us”—so all true knowing depends on what God discloses Quran 2:32.

Revelation is the criterion distinguishing sight from blindness: “Is he who knoweth that what is revealed unto thee from thy Lord is the truth like him who is blind? But only men of understanding heed,” linking understanding to God’s revealed truth rather than unaided speculation Quran 13:19.
