1 Corinthians 3:18 (KJV)

What does 1 Corinthians 3:18 mean?

In 1 Corinthians 3:18, Paul warns that a person can mistake the standards of “this world” for true wisdom. He says that someone who considers himself wise by those standards must be willing to become a “fool” in order to become wise.

Paul addresses people within the Corinthian church who may be confident in their own judgment. His contrast between a wise person and a fool turns their usual measure of wisdom upside down.

The Greek behind 1 Corinthians 3:18

• “deceive” — ἐξαπατάω (exapataō): This word carries the sense of misleading or thoroughly deceiving. Joined with “himself,” the word points to a person being misled by his own judgment.
• “world” — αἰών (aiōn): This word can mean an age or a period of time. Here it gives “this world” the sense of the present age, with its current ways of judging wisdom.
• “fool” — μωρός (mōros): This word means foolish or lacking good sense. Paul uses it within a surprising contrast: the person who becomes a fool does so “that he may be wise.”

Why 1 Corinthians 3:18 matters

• Paul is challenging the way wisdom is measured, not simply praising ignorance. In verse 19, he says that “the wisdom of this world is foolishness with God.”
• The warning concerns the way the Corinthians judge people as well as ideas. In the surrounding passage, Paul addresses their boasting about human leaders, including Paul and Apollos (verses 4–5, 21–22).
