Second Corinthians 6:15 asks two rhetorical questions that point to a simple answer: Christ and Belial do not share common ground, and a believer and an unbeliever do not share the same spiritual portion. In plain terms, the verse means that a follower of Jesus should not form a deep, binding partnership with someone or something that stands opposed to Christ. The apostle Paul wrote these words to the church in Corinth, a busy port city full of temples, trade guilds and idol-linked feasts.
What agreement has Christ with Belial? Or what portion has a believer with an unbeliever?

What 2 Corinthians 6:15 Means
The verse opens with “What agreement has Christ with Belial?” The word agreement translates a Greek term for a harmony or joint understanding, the sort of common mind that lets two parties work together. Belial is an Old Testament term for worthlessness or wickedness, and by Paul’s day it had become a name for the devil or a force of lawlessness. Paul is not asking whether Christ and evil ever get along in theory. He is asking how any real partnership could exist between them.
The second question, “What portion has a believer with an unbeliever?”, uses the word portion in the sense of a share or lot, as in an inheritance or a stake in something. A believer and an unbeliever stand on different foundations, and so their deepest allegiances and hopes lead in different directions. Paul is not saying that believers may never speak with, work beside, or love people who do not share their faith. The verse addresses binding alliances, the kind of partnership that shapes a person’s worship, loyalties and moral direction.
The Context of 2 Corinthians 6:15
Second Corinthians is one of Paul’s letters to a church he had founded and loved, and in this letter he defends his ministry and calls the Corinthians back to wholehearted trust in Christ. Chapter 6 begins with an appeal not to receive God’s grace in vain, and Paul describes his own hardships as a servant of the gospel. Verses 14 through 18 form a short, tightly built passage that sharpens the appeal. Paul moves from questions about light and darkness, to Christ and Belial, to the temple of God and idols, and then to God’s promise to dwell among his people.
Read in that setting, verse 15 is not a general rule about social life. It is part of an argument that the church is God’s temple and must not be yoked to the idolatry that surrounded it. The verses that follow, quoting promises of God’s presence and calling for separation from what is unclean, show that Paul is describing covenant faithfulness. The verse therefore reads best as a call to loyalty to the living God, not as a list of approved and forbidden friends.
Key Phrases in 2 Corinthians 6:15
1 Corinthians 10:21
You can’t both drink the cup of the Lord and the cup of demons. You can’t both partake of the table of the Lord, and of the table of demons.
(WEB)
Paul makes a similar point here, saying that believers cannot share in the table of the Lord and the table of demons. The image of a shared meal shows how a single act of participation can bind a person to a competing allegiance, which helps explain the logic behind the warning in 2 Corinthians 6:15.
Matthew 6:24
“No one can serve two masters, for either he will hate the one and love the other; or else he will be devoted to one and despise the other. You can’t serve both God and Mammon.
(WEB)
Jesus teaches that no one can serve two masters, a teaching that matches Paul’s concern that Christ and Belial cannot be served together. Reading the two passages side by side highlights the call to undivided devotion to God.
A Short Prayer From 2 Corinthians 6:15
Lord, you have called me out of darkness and made me your own. Show me where my loyalties have grown divided, and where I have welcomed partnerships that pull my heart away from you. Give me wisdom to know which relationships and commitments help me follow Christ, and courage to step away from those that do not. Keep my life anchored in your presence, so that I belong fully to you. Amen.
