What causes jealousy among believers?
What causes "jealousy and dissension" among believers, according to 1 Corinthians 3:3?

Setting the Scene

1 Corinthians was written to a church gifted and busy, yet riddled with division. Paul zeroes in on the heart problem before he addresses the symptoms.


The Core Issue in 1 Corinthians 3:3

“for you are still worldly. For since there is jealousy and dissension among you, are you not worldly? Are you not acting like mere men?”

• Worldly (literally “fleshly,” sarkikos) thinking is the cause.

• Living “as mere men” means relying on natural impulses instead of the Holy Spirit.

• Jealousy and dissension are evidence, not the root; the root is a flesh-dominated life.


Signs of Spiritual Immaturity

Paul has just said he could give only “milk” (v. 2). Immaturity shows up when believers:

• Compete for attention and recognition.

• Align themselves with human leaders (vv. 4–5).

• Measure success by worldly standards instead of obedience and love (cf. 1 Corinthians 13:4–5).


How Fleshly Thinking Breeds Jealousy and Strife

• Self-centered ambition (Philippians 2:3).

• Pride in human wisdom (1 Corinthians 1:20–29).

• An appetite for prominence (Mark 10:43–45).

• Failure to walk by the Spirit, which alone produces love, joy, and peace (Galatians 5:16, 22).


Connected Passages

James 3:14–16: “For where jealousy and selfish ambition exist, there will be disorder and every evil practice.”

Galatians 5:19–21: jealousy and strife listed among “the works of the flesh.”

Romans 8:6–8: the mind set on the flesh is hostile to God and cannot please Him.

Together they confirm Paul’s diagnosis: fleshly living always breeds division.


Practical Takeaways for Today

• Cultivate a Spirit-filled mindset: daily surrender to Christ replaces self-interest with His interests (Romans 12:1–2).

• Value every member’s role: God gives growth (1 Corinthians 3:6–7), so boasting in people is pointless.

• Pursue love above giftedness: love “is not jealous… it is not self-seeking” (1 Corinthians 13:4–5).

• Keep the cross central: remembering Christ’s sacrifice humbles pride and unites hearts (Ephesians 2:14–16).

Jealousy and dissension flourish when believers think and act like the world; they fade when hearts yield to the Spirit and glory in Christ alone.
