Verse explainer
"Peace" here isn't a mood to pursue — it's an umpire you're told to let make the calls in your heart.
And let the peace of God rule in your hearts, to the which also ye are called in one body; and be ye thankful.
BSBLet the peace of Christ rule in your hearts, for to this you were called as members of one body. And be thankful.
The plain meaning
The verb translated "rule" (Greek: brabeuō) is an athletic term: it means to act as the umpire or arbitrator in a contest. Paul is not telling the Colossians to feel peaceful. He is telling them to let Christ's peace be the deciding authority when competing impulses — anger, envy, resentment — press for the verdict. Whatever passion is loudest is not the judge; peace is. The phrase "in one body" anchors this personally: this isn't a private spiritual wellness tip. The Colossians are a community, and community is precisely where those passions flare. The call to peace is inseparable from the call to stay in the body together. The closing command — "be thankful" — is not a cheerful add-on. JFB and Gill both note it flows directly from the logic: if you have been called into this body and given this peace, ingratitude is the practical denial of both. Thankfulness is the proof the peace is real.
The common misreading
What the commentators say
Clarke emphasizes the judicial force of the Greek verb: Christ's peace is to act as the brabeus, the contest-judge, deciding and governing in the heart. He draws a sharp practical conclusion — when a believer loses this peace, it is evidence that something else has been lost first; peace ruling is the decisive proof the heart is right with God. Unity in one body is the condition under which that peace can operate.
JFB reads the umpire image as a direct counter to the false teacher of Colossians 2, who set himself up as an umpire and defrauded believers of their prize. Against that usurper, Paul sets Christ's peace as the legitimate arbitrator. When anger or envy arise, they are not to give the award — peace is. JFB also notes that many wear a peaceful face while war rules inwardly, which is precisely what Paul's command refuses to allow.
Gill focuses on the communal dimension: the saints are called in one body, and it is unnatural for members of the same body to quarrel. Peace should bear the sway because strife among believers is a kind of self-harm. He ties thankfulness to the whole package — the calling, the peace, the place in the body — and notes that a grateful spirit is a becoming ornament of a Christian, not a mere emotion.
The word behind it
"Let it rule" or "let it act as umpire." From brabeus, the judge who awarded the prize in Greek athletic contests. This is the only New Testament use of the verb. The force is decisional, not atmospheric — peace is not a background feeling but an active arbitrator. When Paul says "let it rule," he means: when rival claims inside you compete for control, Christ's peace is the one authorized to hand down the verdict. This single word dismantles the popular reading that the verse is about achieving a tranquil mood.
