In this comprehensive blog post, we will explore the major Bible passages that deal with stupidity and summarize the key lessons we can learn.


The Bible has a lot to say about foolish thinking and behavior. Several different Hebrew and Greek words are translated as “fool,” “foolish,” or “stupid” in English translations of the scriptures. The range of meaning includes both intellectual foolishness and moral folly.

Some of the MAIN themes that emerge about stupidity in the Bible include:

  • Fools reject wisdom and exalt their own opinions.

  • Fools are reckless, hasty, and engage in all kinds of sinful behavior.
  • Fools bring harm upon themselves and others.

By examining what the Bible teaches about fools and foolishness, we can gain wisdom to avoid stupid choices and actions in our own lives. Knowledge of God’s word protects us from foolish paths and motivates us toward righteous living.

What Does the Bible Say About Stupidity?

Wisdom and Folly in Proverbs

The book of Proverbs, with its focus on gaining wisdom, has a lot to say about foolishness. According to Proverbs, fools:

  • Despise wisdom and discipline (Proverbs 1:7)
  • Hate knowledge (Proverbs 1:22)
  • Delight in airing their own opinions (Proverbs 18:2)
  • Bring grief to their parents (Proverbs 17:21)
  • Fail to store up knowledge (Proverbs 10:14)
  • Speak perversity and lead others astray (Proverbs 19:1, 15:14)

In contrast to the fool, Proverbs extols the virtue of attaining wisdom, which begins with “fear of the Lord” (Proverbs 9:10). Wisdom leads to blessing, joy, protection, and right living.

Some of the most severe warnings about foolishness come from the wisdom writer. For example:

“Folly is joy to him who lacks sense, but a man of understanding walks straight.” (Proverbs 15:21)

“Whoever loves pleasure will be a poor man; he who loves wine and oil will not be rich.” (Proverbs 21:17)

“The wise of heart will receive commandments, but a babbling fool will come to ruin.” (Proverbs 10:8)

Proverbs gives us practical advice for avoiding foolishness and reminds believers of the value and protection that come from godly wisdom.

Foolishness Toward God

At the heart of foolishness is rejecting or ignoring God. Psalms 14:1 declares, “The fool says in his heart, ‘There is no God.'” Those who deny God’s existence or disregard His ways are truly walking in folly.

Jesus criticized the Pharisees for majoring in minor legal details while neglecting “the weightier matters of the law: justice and mercy and faithfulness” (Matthew 23:23). Whatever keeps us from wholehearted devotion to God qualifies as foolishness.

In God’s eyes, it is foolish to think we can hide our sins from Him:

“Do you think I cannot see your sins? Do you think I cannot hear all your plans? I am the one who made your ears and eyes. I am the one who made your mind. I see everything you do. I know everything you think about.” (Psalm 94:9-11 NCV)

Those who trust in their own reasoning rather than submitting to God’s ways are prone to stray into foolishness:

“Trust in the Lord with all your heart, and do not lean on your own understanding.” (Proverbs 3:5)

When we realize the greatness of God compared to our own limited perspective, we see that forgetting or disobeying Him is the height of foolishness.

Characteristics of Fools

In addition to describing general foolishness, the Bible associates certain behaviors and characteristics with fools:

Flattering speech: “A fool takes no pleasure in understanding, but only in expressing his opinion.” (Proverbs 18:2)

Quick temper: “A man of quick temper acts foolishly, and a man of evil devices is hated.” (Proverbs 14:17)

Scoffing: “Whoever brings derision on a friend—in jest or earnest—will find himself kicked out of the Kingdom.” (Proverbs 14:9, The Voice)

Perversity: “A foolish son is ruin to his father, and a wife’s quarreling is a continual dripping of rain.” (Proverbs 19:13)

Thoughtless haste: “Desire without knowledge is not good, and whoever makes haste with his feet misses his way.” (Proverbs 19:2)

Unwise spending: “He who gathers money little by little makes it grow.” (Proverbs 13:11)

Understanding these and other foolish behaviors enables us to identify and uproot sinful patterns in our lives. God gives us wisdom so that we can live uprightly rather than falling into moral and spiritual ruin.

Consequences of Folly

Why does the Bible devote so much space to describing fools and warning against foolishness? Because stupid choices result in painful consequences! Proverbs is full of statements about outcomes that befall the foolish:

  • “The foolish inherit folly.” (Proverbs 14:18)
  • “The way of a fool is right in his own eyes.” (Proverbs 12:15)
  • “As a dog returns to its vomit, so a fool repeats his folly.” (Proverbs 26:11)

Here are some other consequences mentioned:

Poverty: “Folly brings joy to those with no sense; a sensible person stays on the right path.” (Proverbs 15:21 NLT)

Strife: “It is an honor for a person to cease from strife, but every fool quarrels.” (Proverbs 20:3)

Rejection: “When the godly are in authority, the people rejoice. But when the wicked are in power, they groan.” (Proverbs 29:2 NLT)

Death: “Folly leads to death, her steps lead straight to the grave.” (Proverbs 7:27 NLT)

By embracing wisdom, we can avoid these painful outcomes!

Overcoming Foolishness

Since foolishness brings destruction, we should actively turn from it. Scripture gives this advice for leaving foolishness behind:

  • Listen to correction. “Whoever loves discipline loves knowledge, but he who hates correction is stupid.” (Proverbs 12:1)
  • Accept instruction. “Forsake folly and live, and walk in the way of insight.” (Proverbs 9:6)
  • Choose wise companions. “Whoever walks with the wise becomes wise, but the companion of fools will suffer harm.” (Proverbs 13:20)
  • Bridle the tongue. “Even a fool who keeps silent is considered wise; when he closes his lips, he is deemed intelligent.” (Proverbs 17:28)

As we partner with God to resist foolish impulses, He will guide us into greater wisdom resulting in right living and blessing.

Key Takeaways on Stupidity in the Bible

Here are some of the main truths that we learn about foolishness from God’s word:

  • Fools reject wisdom, exalt their own opinions, and refuse correction.
  • They make choices without considering God or consequences.
  • Foolishness angers God, grieves others, and leads to pain and ruin.
  • Scoffing, quick temper, flattery, and haste mark the fool.
  • Turning from foolishness, fearing God, and obeying wisdom leads to life and joy.
  • God offers wisdom so that we can walk in righteous, prudent ways.

Understanding what the Bible says about stupidity gives us a strong foundation for rooting foolish patterns out of our lives. As we embrace wisdom and discretion, we experience God’s protection and blessing.


Foolishness is a serious topic because it leads to destruction and separation from God. Thankfully through His word, God makes us wise regarding good and evil, equipping us to turn from stupidity and unto His righteousness.

By examining what scripture teaches about fools and their characteristics, we can identify areas of potential foolishness in our lives. As we yield them to God and embrace biblical wisdom, our thinking and choices will align with His will more and more. Fear of the Lord keeps us from evil and empowers us to walk in steadfast devotion to Him.

What an amazing gift we have in God’s word! His Spirit uses it to cut through rationalizations and convict us of foolish behaviors we have clung to. As we study the Bible, our minds are renewed so that we discern the shortsightedness of sin and walk in the wise ways of God. His truth sets us free to enjoy the abundant life He desires for each of us.
