Know in Part, Prophesy in Part: 1 Corinthians 13:9-12
Short answer: In 1 Corinthians 13:9-12, Paul writes, "For we know in part and we prophesy in part," meaning that every revelation, every prophetic word, and every act of understanding available to us now is partial and incomplete. This is not a defect in God's character but a limit built into the present age. Because our knowledge is partial, we must hold our gifts and convictions with humility, speak with charity toward those who differ, and look forward to the day when partial things pass away and we see face to face. The passage does not tell us never to prophesy or study; it tells us to do both as people who know that our vision is real but unfinished.
What Paul Means by Knowing in Part
The word Paul uses for knowing, ginosko, describes knowledge that is real but limited. He is not saying that Christians know nothing, or that our knowledge of God is unreliable. He is saying it is incomplete. We genuinely know God through Christ, yet the knowledge of a finite creature about an infinite Creator will always be partial in this life. Verse 9 states the point plainly: 1 Corinthians 13:9-12 says, "For we know in part and we prophesy in part." Paul places knowledge and prophecy together because both are ways of receiving and communicating truth from God. Neither reaches the ceiling of what God knows.
This matters because the Corinthian church had a problem with spiritual confidence. They prized certain gifts and certain knowledge as markers of status. Some in Corinth evidently thought their insight lifted them above others. Paul's correction is gentle but firm: whatever you know, you know in part. The comparison is not between knowing and not knowing, but between the partial and the complete. What we have now is not the whole picture, and this should make us modest rather than boastful.
The same is true of our study of Scripture. A faithful teacher who has spent decades in the text still sees through a glass, not face to face. That does not mean study is pointless. It means the most mature knowledge still has an edge of incompleteness. Paul, who wrote more of the New Testament than anyone, included himself among those who know in part. The limitations he describes are not the limits of an immature believer but the limits of the present age.
Practically, this shapes how we argue about secondary matters. If our knowledge is partial, then some of our strongest convictions may need to be restated when we learn more. It also shapes how we treat those who disagree with us. A person who knows in part has reason to listen before correcting. Paul did not use this reality to flatten all truth into opinion. He used it to deflate pride that treated partial knowledge as if it were final.
Prophesy in Part: Why Even Revelation Is Not Exhaustive
Paul joins prophecy to knowledge because prophecy is one of the clearest ways God speaks to his people. In 1 Corinthians 14:1-5 he writes, "Follow after love and earnestly desire spiritual gifts, but especially that you may prophesy." Prophecy is not something Paul discourages; he tells the Corinthians to desire it. Yet even prophecy is partial in the present age. The prophet receives a word, and the word is true, but it does not contain everything. It is a fragment of God's counsel, not the whole.
This is important because prophecy in Scripture has always carried the danger of false claims. Deuteronomy 18:20 warns about the prophet who speaks presumptuously in God's name, which I have not commanded him to speak, or who speaks in the name of other gods. The partial nature of prophecy is not an excuse for errors, but it does explain why prophecy must be weighed. Paul tells the Corinthians elsewhere to test what they receive. A partial word spoken into a limited moment may be truly from God without being the final word on a matter.
Prophecy in the New Testament builds up the church, encourages, and comforts. That is a real function, and no church should despise it. But the one who prophesies is not a source of infallible information about the future or about every problem in the room. Paul's own limitations are part of the picture he draws. He prophesied and wrote Scripture, and he still insisted that he knew in part and prophesied in part. If Paul's knowledge was partial, ours is certainly partial too.
This gives a practical safeguard. When someone brings a prophetic word, the church should welcome it without treating it as automatically equal to Scripture. It must be measured against Scripture, which is the sure word we have been given. A genuine word from God will never contradict what he has already said. But even a genuine word may be one small piece of something larger that only God sees fully.
The Contrast with What Is Complete
Paul's argument turns on a contrast. The partial is temporary; the complete is coming. Verse 10 says that when that which is perfect has come, that which is in part will be done away. The partial and the complete are not two levels of the same thing; they belong to two different ages. The present age is the age of partial knowledge, partial prophecy, partial understanding. The age to come is the age of seeing face to face.
Many interpreters have debated exactly what moment Paul has in view. Some think the perfect refers to the completion of the New Testament Scriptures, others to the return of Christ, and others to the maturity of the church. Faithful Christians have differed. What is clear, and what the passage itself states, is that the partial will be replaced by the complete. The verbs Paul uses are decisive: knowledge and prophecy will be done away with, not because they were evil, but because they are fulfilled in something greater.
This should make us careful in how we use the gifts now. They are genuine, but they are provisional. A Christian who is deeply shaped by prophecy knows that prophecy is not the destination. A teacher who loves doctrine knows that doctrine is a road, not the final room. We are being carried toward a vision that will not need explanation. The whole movement of the passage is forward: from partial, to complete; from childhood, to adulthood; from a mirror, to a face.
Paul does not describe the present gifts with contempt. He describes them precisely so that the Corinthians will stop treating them as ultimates. The gifts that were causing so much competition will one day be unnecessary. That perspective frees a congregation from jealousy over who has the most impressive gift. If the gift itself is temporary, then the better question is how we love one another while using it.
Love: The More Excellent Way in Times of Partial Knowledge
First Corinthians 13 sits in the middle of Paul's discussion of spiritual gifts. Chapter 12 lists the gifts. Chapter 14 gives instructions for their use. Chapter 13 shows the character that must govern all of them. Verses 9 through 12 are not a digression about epistemology; they are part of an argument about love. Because we know in part, love is indispensable. A person who knows in part but loves fully is more useful to the church than a person who knows more but loves little.
The famous line about love never failing comes just before verse 9. Love outlasts prophecy, languages, and knowledge. The partial gifts will be done away with. Love will not be. That means the measure of a Christian's life is not the quantity of revelation received but the quality of love practiced. This is where so much of our arguing about secondary things misses the point. We can win a debate about prophecy and lose the room by failing to love the person we are correcting.
Paul's phrase about knowledge puffing up belongs in this context. Knowledge with love builds up; knowledge without love produces pride. Because our knowledge is partial, pride is always a false conclusion. We have not reached certainty so great that we may treat others with contempt. The way we hold truth matters. If we are still children in understanding and still looking through a glass, then humility is not optional for the teacher.
Love also determines how we handle the limits of others. Every believer in the room knows only in part and prophesies only in part. The person who is less informed should be taught without humiliation. The person who is more informed should teach without display. Love makes room for the fact that no one has arrived. In this way, 1 Corinthians 13 reframes church life: the goal is not to be the one who sees most clearly, but the one who loves most faithfully while we all wait to see.
Seeing Face to Face: The Hope That Steadies Us
Verse 12 gives us one of the most memorable images in Paul's letters: 1 Corinthians 13:12 says, "For now we see in a mirror, dimly; but then face to face." The mirror Paul has in mind is probably not a modern glass mirror but a polished metal surface that gave an imperfect and obscure reflection. Compared with the direct sight he is promising, the best reflection of God we have now is faint. Then, however, we will see clearly. That hope is the anchor for all who are weary of partial understanding.
The second half of verse 12 is stunning: 1 Corinthians 13:12 says, "Now I know in part, but then I will know fully, even as I was also fully known." The knowing Paul anticipates is not an infinite knowledge, for the creature never becomes the Creator. It is a complete and accurate knowledge, the kind of knowing that corresponds to being fully known. God already knows us through and through. One day our knowledge of him will match the comfort of being known by him, without distortion, without gaps.
For the church, this hope settles debates we cannot resolve now. Some questions about prophecy, about the timing of the perfect, about the details of the last things, remain open because our knowledge is partial. We should not pretend otherwise. But we can be patient with one another because we all confess the same future: we will see face to face. The differences that seem so large now will shrink in that light, and the things we agree on will appear as the foundation they always were.
There is also comfort for the grieving, the confused, and the suffering. Many of our questions will not be answered in this life. Paul does not say that if we study enough we will solve every mystery. He says that the partial is temporary. The day is coming when the mirror will be put away. Until then, we do what Paul says: we hold to love, we use our gifts honestly, and we look for the morning star to arise in our hearts.
How Partial Knowledge Should Change Our Teaching
If every teacher knows in part, then every sermon and lesson should sound like it comes from a person who knows in part. That does not mean endless hedging. A teacher can be confident and still be finite. The distinction is between saying more than we know and saying exactly what we know with the humility it deserves. A healthy pulpit presents Scripture as absolutely true and the teacher as a partial interpreter who may be wrong about some of the details.
This also means that church discipline of doctrine must be proportionate. There are essential matters on which we cannot compromise, because they are clearly taught and denial of them breaks the faith. But many disputes in church history have been about matters that were never finally settled. Paul's words create a category for faithful disagreement. Two believers may both love the Lord and hold different views on prophecy or secondary doctrines, and neither should be treated as an enemy.
A teacher who knows in part will welcome correction. He will not assume his first reading is infallible. He will welcome questions. He will listen to those who disagree, not only to refute them but to test his own understanding. This is not weakness; it is the realism of verse 9. The one who thinks he has finished learning has probably stopped learning. The one who knows in part keeps studying, keeps praying, keeps checking his reasoning against the whole of Scripture.
Ephesians 4:11-14 gives the goal of the teacher's work: the body is built up until we all reach maturity, no longer children tossed around by every wind of doctrine. That is a process, and it will not finish until Christ returns. Teachers are instruments in the process, not the end of it. Their gifts are partial, but by God's grace they are used to carry the church toward the complete. The teacher who understands this serves with patience, knowing he is one small part of a much larger work.
Living with Partial Knowledge Without Losing Confidence
Some Christians become paralyzed by the idea that we know in part. If none of us has the full picture, how can we be sure of anything? Paul does not lead us there. He is confident about the gospel, confident about the resurrection, confident about the love of God. His point is not that everything is uncertain, but that our grasp of even certain truth is not exhaustive. We can be fully confident in what God has plainly said while remaining humble about what he has not said.
The difference is between the reliability of God's word and the reach of our understanding. God's word is true and fully trustworthy. Our understanding of it grows and sometimes changes as we mature. A child who knows his father loves him is not wrong, but he does not know the depth of that love until much later. In the same way, we can rest on the promises of God while acknowledging we have not yet plumbed their full depth. The partial knowledge of a believer is not shaky knowledge; it is real knowledge that is not yet complete.
This reality also keeps us from attaching our identity to having the best answer. The person who must always be right is usually the person most afraid of being found incomplete. The gospel frees us from that fear. We are loved by God through Christ, and our standing does not depend on winning every argument. We can say that we do not know and still be secure. We can change our view and still be faithful. We can hold our convictions firmly and hold them with an open hand where Scripture has not closed the matter.
Finally, living with partial knowledge should make us eager for the day when partial things are done away with. That hope is not escapism; it produces endurance. The church has always been full of people who saw dimly and loved deeply. They held on to the promises, taught what they could, corrected where they must, and waited. Paul's words to Corinth reach down through the centuries to us: we know in part, we prophesy in part, and we will see face to face.
Biblical fidelity check
1 Corinthians 13:9-12 establishes that knowledge and prophecy in this age are partial. It does not establish that Christians cannot be sure of what God has plainly revealed. It does not say all opinions are equal or that doctrine does not matter. It says that our access to truth now is limited and incomplete compared with the direct knowledge of the age to come. The passage also does not define exactly when the partial will be done away with; faithful interpreters have placed that moment at different points, and the text itself leaves that debate open.
A common misreading treats Paul's words as a reason to distrust prophecy, teaching, or study altogether. This is wrong because Paul commands the Corinthians to earnestly desire spiritual gifts, especially prophecy, in 1 Corinthians 14:1-5, and he tells them to follow after love. Another misreading is the opposite error: treating a current prophetic word or a teacher's insight as if it were the complete and final word of God. Paul says the opposite. Until we see face to face, our greatest certainty is Christ himself, and our greatest duty toward one another is love while we wait for sight.
Other passages that speak to 1 Corinthians 13:9-12
Several related studies help place this passage in the wider argument of 1 Corinthians. What Does 1 Corinthians 1:10 Mean? Context, Theology, and Application shows why Paul's call to unity matters so much for a church tempted to rank its gifts. What Does 1 Corinthians 1:9 Mean? Context, Theology, and Application grounds that unity in God's faithfulness, not human unanimity. 1 Corinthians 1: Called, United, and Boasting in the Lord traces Paul's opening themes of calling and humility. 1 Corinthians 10: Warnings and Freedom adds the practical shape of living wisely where knowledge and freedom have limits.
Frequently asked questions
If we know only in part, can we be certain about the gospel?
Yes. Paul's point is that our grasp of truth is incomplete, not that the truth itself is uncertain. The same apostle who wrote that we know in part also wrote that Christ died for our sins and rose again. We can be fully confident in what God has plainly revealed while remaining humble about secondary matters and future details we cannot fully see. Partial knowledge is real knowledge; it is simply not exhaustive. The certainty of the gospel rests on God's character, not on the reach of our understanding.
Does the passage teach that prophecy has already ceased?
No. The passage states that prophecies will be done away with, and it says the same about knowledge, which no one claims has ceased. Paul is contrasting the partial present with the complete future, not announcing the end of specific gifts at a certain date. Faithful Christians have held different views about when prophecy ceases and about what the perfect refers to. The text itself does not settle that timeline. What it clearly says is that our prophecy, like our knowledge, is partial now.
How should this affect how I handle disagreements with other believers?
It should make us humble and patient without making us indifferent. Since all of us know in part, no one should treat a secondary opinion as if it were the final word of God. We can hold convictions firmly while listening honestly, being willing to change when Scripture and good reasoning point elsewhere. At the same time, love does not mean pretending that every view is equally true. We contend for the faith once delivered, and we do it with gentleness, remembering that we too may be wrong about some details.
