1 Corinthians 3:18-23: Don't Fall for Self-Deception

September 19, 2026 Blaize

Self-deception occurs when someone tricks themselves into believing something untrue. It is akin to convincing oneself of something because it aligns with one's desires, even if deep down, the person recognizes its falsehood. This arises when individuals hold conflicting beliefs, creating discomfort. To alleviate this, they might deceive themselves, making everything appear congruent. The extent and nature of self-deception are shaped by cultural and social norms. The Corinthians grappled with a message that contradicted the prevailing worldviews and popular opinions of their time. Paul dedicated the initial sections of this letter to outlining these differences.

The New Testament discusses self-deception in various ways:

James 1:22: "But be doers of the word, and not hearers only, deceiving yourselves."

James 1:26: "If anyone thinks he is religious and does not bridle his tongue but deceives his heart, this person's religion is worthless."

1 John 1:8: "If we say we have no sin, we deceive ourselves, and the truth is not in us."

Galatians 6:3: "For if anyone thinks he is something, when he is nothing, he deceives himself."

2 Timothy 3:13: "While evil people and impostors will go on from bad to worse, deceiving and being deceived."

All these contexts point to some kind of self-deception: hearing and not doing, possessing a deceptive tongue, claiming one is without sin, thinking too highly of oneself, and succumbing to deception directly. To avoid these pitfalls, Paul gives a straightforward solution to avoid self-deception: embrace what the world deems “foolishness.” This doesn't mean one should act foolishly for God's sake. Instead, one should become “foolish” in the eyes of people to align with God's ways. One should stop attempting to reconcile their newfound faith with the dominant worldview. It's akin to trying to mix oil with water; the two won't combine. After all, God's wisdom is superior, and it takes the Spirit of God to understand it. Paul references Job 5:13 and Psalm 94:11 to underscore this. In essence, taking pride in anything other than Christ equates to self-deception. To combat self-deception, believers must continually embrace a humble posture toward God and His wisdom. By doing so, one can be viewed as "foolish" by worldly standards and yet be truly wise in spirit!

Lord, make me foolish in worldly ways, so I can be wise in Yours!
