2 Corinthians 6:15
The Text
Paul fires off a question that lands like a stone in still water: what agreement does Christ have with Belial? And then, immediately after, a second one, quieter but sharper: what portion does a believer have with an unbeliever? He is not building an argument so much as holding up two things that cannot be held together and letting the Corinthians feel the strain in their own hands. Belial is an old name for worthlessness, for ruin, used in Jewish writing of Paul's day as a name for the adversary himself. The question is rhetorical, yes, but it is still a question. Paul does not answer it. He leaves the space open, and the open space is where the Corinthians, and we, have to stand.
The Core
What makes this verse hard is not its severity but its assumption: that there is a line in reality, and that line runs through loyalties, not merely through behavior. Paul is not saying believers are better people. He has just finished listing beatings, imprisonments, dishonor, being treated as deceivers. He is saying that Christ and Belial want incompatible things, and a human life cannot finally serve both. The word rendered agreement carries the sense of a shared voice, a harmony, the way two notes either blend or clash. Paul hears a clash. And the question he asks is not whether we approve of the unbeliever, but what portion, what inheritance, what final share we are counting on. Where is your treasure actually banked? The verse refuses to let that stay vague.
The Common Thread
The logic of this question is older than Corinth. From Sinai onward God separates a people, not because they are impressive but because He intends to live among them: "I will dwell in them and walk in them," Paul quotes two verses later, and the walking is the point. A God who walks in the middle of a camp makes the camp a different kind of place. Israel's long failure was not that she stopped believing in the Lord but that she kept adding other names alongside His. Then Christ comes and does the impossible thing: He crosses the line Himself, goes to the unclean, touches the leper, and absorbs the separation in His own body. The line does not disappear. It is relocated to the cross, and we are drawn across it.
The Mirror
The uncomfortable part is that Paul's question is not about company but about agreement, and agreement is quieter than company. You can work beside anyone. The question is whose verdict on your life you are actually waiting for. Which voice would hurt you most if it turned against you: the voice of Christ or the voice of your field, your family, your industry? Most of us never consciously choose Belial. We simply discover, around the time of a promotion or a diagnosis or a dispute over money, that our hope has been quietly spread across two accounts. The verse asks where the portion is. Not where the membership is.
Today, write down the one decision this week where you can feel the pull of two loyalties, name both out loud, and say which one you intend to follow.
The Main Character
Watch Paul in this chapter and you see a man with an open mouth and an enlarged heart, pleading, almost begging, and then suddenly going hard as flint. That combination is the shape of real love, not its contradiction. He has already said, "You are not restricted by us, but you are restricted by your own affections." He is not defending his honor; he is afraid for them. A father who sees his child drifting toward something ruinous does not negotiate tone. The emotional landscape here is tenderness under pressure, affection that has become urgent. If Paul seems severe in verse 15, it is because he has already made himself wholly vulnerable in verse 11.
The Intertext
Jesus says it with money rather than with Belial: no one can serve two masters, for he will either hate the one and love the other. The structure is identical, a division that lives in the heart before it shows in the calendar. And the Lord's call in verse 17, "Come out from among them, and be separate," is a quotation from Isaiah's summons to Israel leaving Babylon, a people told to walk out of an empire carrying the vessels of the temple. Paul takes an exodus text and applies it not to geography but to loyalty. The Corinthians are not told to leave the city. They are told to stop belonging to it in the way they have.
The Detail
Portion. The Greek word behind it belongs to the world of inheritance, the share allotted to each tribe when the land was divided. The Levites, famously, got no portion of land, because the Lord Himself was their portion. So Paul's question has teeth: what share of the inheritance do you hold jointly with someone who is not expecting that inheritance? It is not a question about friendship or marriage in the first place. It is a question about the long run, about what you are counting on when everything else is gone. And Paul lets it hang there, unanswered, because the answer has to be yours.
Reflection
Where in your life have you been treating a question of loyalty as if it were merely a question of schedule or company?
If the Lord Himself is your portion, what would change this month in how you handle what you own?

Insights, prayers and thanksgivings from readers and the editorial team on this passage.
A yoke is not a fence, it is a harness. Two animals, one field, one pace, one direction. So Paul asks, "what fellowship has light with darkness?" The question is not who you are allowed to love. It is who sets your direction. Look at the furrow your life is cutting lately. Who is pulling beside you, and where are you being pulled?
Paul has just finished listing beatings, prisons, sleepless nights. Then, without pausing, he adds "in kindness... in sincere love." That's the wonder of it. All that hardship didn't harden him. Suffering usually makes us guarded, quick to protect ourselves. Ask yourself honestly: has your pain made you gentler, or safer?
Paul lists his credentials: "in beatings, in imprisonments, in riots, in labors, in watchings, in fastings." Notice the turn halfway through. The first three were done to him. The last three he chose. Suffering found him, and then he added more, freely, out of love. Sleepless nights nobody asked him to keep. What would you willingly give up for someone who could never repay you?
Father, it still surprises me that you choose to live in people like me. Make my life a place where you're at home. Clear out what doesn't belong, and walk with me through ordinary days, until it's obvious whose I am.
