Job 38
1. God challenges Job to answer
4. God, by his mighty works, convinces Job of ignorance
31. and weakness














Surely you know,
This phrase is part of God's response to Job, highlighting Job's limited understanding compared to God's infinite wisdom. It emphasizes the theme of human limitation in comprehending divine mysteries. This rhetorical question underscores the irony, as Job, a mere human, cannot possibly know the intricacies of creation and the universe. This aligns with other biblical passages that stress God's omniscience, such as Isaiah 55:8-9, where God's thoughts and ways are higher than human understanding.

for you were already born!
Here, God sarcastically suggests that Job must have been present at the creation of the world to possess such knowledge. This highlights the absurdity of human presumption in questioning God's governance. The phrase serves to remind readers of the temporal nature of human existence compared to God's eternal nature. It echoes the sentiment found in Psalm 90:2, which speaks of God's eternal existence before the mountains were born.

And the number of your days is great!
This statement further emphasizes the irony, as Job's lifespan is insignificant compared to God's eternal existence. It serves as a reminder of the brevity of human life, a theme also found in James 4:14, which compares life to a mist that appears for a little while and then vanishes. The phrase challenges readers to recognize their own limitations and the futility of questioning God's purposes without understanding His eternal perspective.

Human Limitations
Recognizing our limited understanding should drive us to rely on God's wisdom rather than our own insights.

The Importance of Perspective
God's questions to Job remind us to view our circumstances from a divine perspective, acknowledging that God's ways are higher than ours.

Trust in God's Sovereignty
Even when we do not understand our suffering or circumstances, we can trust that God is in control and His purposes are good.

The Role of Faith in Uncertainty
Faith involves trusting God even when we lack answers, believing that He knows the number of our days and has a plan for our lives.

What Does Job 38:21 Mean
Surely you know

• God’s opening words in Job 38:21 drip with gentle irony. After asking Job about the storehouses of snow and hail (Job 38:22–23), the Lord mockingly assumes Job must already grasp such mysteries.

• The statement highlights the vast gap between divine and human understanding, echoing earlier confessions that “the fear of the Lord, that is wisdom” (Job 28:28) and that God’s thoughts are higher than ours (Isaiah 55:8–9).

• Similar divine challenges appear in Job 38:2, “Who is this who obscures My counsel by words without knowledge?” and in Romans 11:33, where Paul marvels, “Oh, the depth of the riches of the wisdom and knowledge of God!”—all underscoring that true knowledge begins with acknowledging God’s supremacy.


for you were already born!

• The Lord’s sarcasm underlines that Job was not present at creation. “Where were you when I laid the foundations of the earth?” (Job 38:4) confronts Job with his temporal limits.

• Bildad had earlier asked, “Are you the first man ever born?” (Job 8:8–9), and Eliphaz quipped, “Were you the first man ever born? Were you brought forth before the hills?” (Job 15:7). God now makes the same point: only the Creator witnessed the dawn of creation (Psalm 90:2; John 1:1–3; Colossians 1:16).

• By exposing Job’s absence at creation, the Lord reminds every reader that all human insight is secondhand and derivative.


And the number of your days is great!

• The phrase keeps the ironic tone: compared to the Ancient of Days (Daniel 7:9; Psalm 102:25–27), our lives are fleeting. “For we are but of yesterday and know nothing” (Job 8:9) and “You have made my days a few handbreadths” (Psalm 39:4–5) echo this brevity.

• God contrasts His eternal existence with Job’s finite lifespan: while human days might reach “seventy years, or eighty if we have strength” (Psalm 90:10), the Lord remains “from everlasting to everlasting” (Psalm 90:2).

• Recognizing our mortality fuels humility and dependence on the God whose “power is made perfect in weakness” (2 Corinthians 12:9).


summary

Job 38:21 delivers a three–fold rhetorical sting: “Surely you know,” “for you were already born,” and “the number of your days is great.” Each phrase exposes the limitations of human knowledge, presence, and longevity when set beside the omniscience, omnipresence, and eternality of God. The verse calls believers to humble awe, trusting the Creator whose wisdom towers above every human insight and whose purposes—though often mysterious—are always righteous and true.

(21) Knowest thou it?--It is better to read this verse without an interrogation, as sublime irony. "Doubtless thou knowest all this, for thou wast born then, and the number of thy days is so great!"

Verse 21. - Knowest thou it, because thou wast then born? The irony that has underlain the whole address comes here to the surface, and shows itself palpably. Job, of course, is as old as the Almighty, or, at any rate, coeval with creation; otherwise he could not presume to take the tone which he has taken, and arraign the moral government of the Creator. Or because the number of thy days is great! Compare the sarcasm of Eliphaz (Job 15:7).
