Matthew 13: Leave the Harvest to the Son of Man

Introduction

“If the kingdom of God has come, why is there still so much evil in the world? If the Holy Spirit has been poured out, why is the field so mixed?” Malcolm Duncan, a pastor at Kensington Temple in London, opens the third part of his series on the parables of the kingdom in Matthew’s Gospel with these questions. The series title is borrowed from a book by the biblical scholar Walter Brueggemann: texts that linger, words that explode.

The passage is the parable of the weeds (Matthew 13:24-30, then 36-43). A man sows good seed in his field; while people sleep, an enemy sows weeds among it. The servants want to pull everything up. The master answers: “Let both grow together until the harvest.” Jesus does not give a philosophical answer to the problem of evil, the preacher points out: he gives a field, wheat, weeds, impatient servants, and a master who has the wisdom to wait.

The message comes down to four ideas: the kingdom begins with good seed, the enemy works through hidden imitation, the servants must resist sorting people too soon, and the Son of Man will bring a final, just harvest. It ends with a personal question: what kind of plant are you becoming?

Outline of the Message

1. The Kingdom Begins with Good Seed

• The first thing Jesus wants to show us is not the weeds, it is the seed. “We can be so fascinated by what has gone wrong that we forget what God has done right.” The initiative in the story belongs to the sower, not to the enemy.
• The field belongs to the sower, the seed comes from him, and the harvest is expected by him. The enemy is real, but he is not ultimate.
• The sower is the Son of Man (Matthew 13:37). The title points back to Daniel 7, where one like a son of man receives dominion, glory, and a kingdom. Matthew uses it in three ways: for Jesus’ authority (forgiving sins, Matthew 9:6; Lord of the Sabbath, Matthew 12:8), for his suffering (Matthew 16:21; 20:28), and for his return in glory (Matthew 16:27; 24:30; 26:64).
• So the sower is not just a wandering teacher of morals. He is the royal Son of Man, to whom belongs not a part, but all authority.
• Malcolm Duncan states that in the last twenty-four hours, more people have become disciples of Jesus than at any other moment in history. “Don’t let the presence of weeds convince you that the sower has stopped sowing.” The field is mixed, but the seed is good, and the field still belongs to God.

2. The Field Is the World, and You Are Sown in It

• Jesus says it plainly: “the field is the world” (Matthew 13:38). The world is not an abandoned territory. The kingdom is not reduced to private piety: it touches homes, schools, hospitals, businesses, city councils and parliaments, art, technology, and the economy.
• Every legitimate vocation is a place of witness: not only the preacher or the evangelist, but the care worker, the doctor, the entrepreneur, the politician, the friend.
• The difference from the parable of the sower: there, the seed was the Word; here, “the good seed is the children of the kingdom.” The Word is sown in people, and those people are sown in the world.
• As the week before, the pastor insists: the parables are not about other people, they are about us. Where you live, work, and rest, God has sown you.
• “God doesn’t save us just to bring us to church. He saves us and gathers us to form us, and he forms us to scatter us.” The gathered Church is a community of worship; the scattered Church is the presence of the kingdom. Wheat doesn’t exist to sing about the field: it grows in the field.
• The image runs through all of Scripture: Joseph preserving life during the famine, Ruth gleaning in the fields, those who sow in tears and reap with songs of joy (Psalm 126:5), Paul planting while Apollos waters, “but God gave the increase” (1 Corinthians 3:6).

3. The Enemy Works Through Hidden Imitation

• “But while people slept, his enemy came and sowed darnel also among the wheat, and went away” (Matthew 13:25). The enemy doesn’t burn the field or attack the servants: he sabotages by imitation, in secret, and disappears.
• Jesus names the enemy without embarrassment: “The enemy who sowed them is the devil” (Matthew 13:39). This does not mean every annoyance is a demon, or that human beings are no longer responsible. Talk of the devil should not make us less responsible, it should make us more clear-eyed.
• The weed in question is often identified as a plant that looks like wheat in its early stages: you can’t see the difference until growth reveals it. The enemy doesn’t merely oppose God’s purposes, he imitates them.
• “A lie is most dangerous when it looks like the truth.” Abuse is most dangerous when it borrows the language of biblical authority, and “Nationalism is most dangerous when it borrows God’s divine purpose and turns it into a nation’s purpose.” Cowardice is most dangerous when it calls itself wisdom, greed when it calls itself blessing, control when it calls itself leadership, prejudice when it calls itself discernment.
• Jesus often warns against this counterfeit: false prophets in sheep’s clothing (Matthew 7:15), those who say “Lord, Lord” without doing the Father’s will (Matthew 7:21), those who honor God with their lips (Matthew 15:8), the cup clean on the outside and full on the inside (Matthew 23:25).

4. Discerning Without Suspicion or Dehumanizing

• The parable calls for discernment, but discernment is not suspicion. “Sometimes it is an untreated fear that has put on theological clothing.” Biblical discernment is the Spirit-given ability to recognize the character and purposes of Jesus in someone.
• “By their fruits you will know them” (Matthew 7:16): not by the volume of the voice, the size of the platform, or the number of followers. Maturity always reveals identity. Hence the call not to appoint leaders hastily (1 Timothy 5:22): charisma is immediate, character is revealed over time.
• As a Pentecostal theologian, he pleads for holding gifts and fruit together: power and holiness, prophecy and truth, boldness and gentleness, apostolic vision and pastoral patience.
• “Children of the evil one” describes a spiritual and moral allegiance, not permission to label your neighbors as beyond recovery. An allegiance can change: God “delivered us out of the power of darkness, and translated us into the Kingdom of the Son of his love” (Colossians 1:13). Paul was a persecutor before he was an apostle.
• Malcolm Duncan grew up in Northern Ireland during the Troubles. His best friend was killed along with his father, and a loved one was seriously wounded in an attack in Belfast. He saw how “them and us” erases the image of God in the other person. He contributed to a document for the peace process titled “A Shared Future”: the future was going to be shared anyway, the only question was how.
• “If our defense of the truth makes us cruel, something is wrong.” We must discern the work of the enemy, without ever adopting his methods.

5. The Servants Must Resist Sorting People Too Soon

• The servants’ first question: “Sir, didn’t you sow good seed in your field? Where did this darnel come from?” The master’s answer: “An enemy has done this” (Matthew 13:27-28). “If you forget everything else, don’t forget this: evil does not come from the character or the intention of the sower.”
• Evil is a parasite: it cannot create, only corrupt what exists. Injustice twists authority, greed twists provision, lust twists desire, racism twists difference, sectarianism twists belonging.
• The second question: “Do you want us to go and gather them up?” The master answers: “No, lest perhaps while you gather up the darnel, you root up the wheat with them” (Matthew 13:29). The problem is not that the servants care too much about holiness, it is that they overestimate their ability to judge without causing damage.
• The Church has sometimes reached too quickly for the weapons of exclusion, treating difference as a threat, questions as rebellion, and wounds as disobedience. “Don’t destroy people to clean something up.”
• Jesus is the servant who “will not break a bruised reed” and “will not quench a smoking flax” (Matthew 12:20, quoting Isaiah 42:3): strong enough to confront evil, gentle enough not to destroy the wounded. “That is what a pastor is.”

6. Patience Is Not Passivity

• “Let both grow together” does not mean tolerating abuse, hiding crimes, or leaving the vulnerable unprotected. Other texts require discipline: the process of Matthew 18:15-17, the shepherds who guard the flock (1 Peter 5:2), the authorities charged with public justice (Romans 13:1-4).
• “Protecting vulnerable people is not a lack of grace. Accountability is not the enemy of restoration.” The Church can say: this behavior must stop, this person cannot hold a position of responsibility here. That is its role.
• What it cannot say is that it knows infallibly a person’s final destiny. He cites a saying he attributes to John Wesley: “betwixt saddle and ground, mercy sought is mercy found.”
• He lives this personally: his father came to faith the night he died, and many told him his father was lost. He only knew he could not claim that. Ten years later, a woman he had met only once described that last night to him in detail, details that no one knew.
• The parable speaks to two Churches. To the Church that is too permissive: the weeds are real, deal with them, but in God’s time. To the Church that persecutes: you are not the Lord of the harvest.
• In public life too: yes to engagement against poverty, human trafficking, racism, or corruption, but without confusing cultural influence with control by coercion. “Conviction without coercion, courage without contempt, prophetic clarity without dehumanizing, patience without passivity.” And the end never justifies the means.
• “Leave room for repentance, for formation, for the work of the Spirit, for grace. Leave room for God to surprise you.”

7. The Son of Man Will Bring a Final, Just Harvest

• The decisive words are “until the harvest.” Patience is not permanence: delaying judgment is not denying it. We live between the sowing and the harvest, between the resurrection and the return of Jesus.
• “The harvest is the end of the age. The reapers are angels” (Matthew 13:39). The image runs through Scripture: the prophets, John the Baptist with his winnowing fork in his hand (Matthew 3:12), the sheep and the goats (Matthew 25:31-46), the Son of Man with a sharp sickle (Revelation 14:14-16).
• “A gospel that never speaks of judgment ends up unable to speak truthfully to the victims of history.” What can we say to families destroyed by war, to survivors of abuse, to communities plundered by corruption? The Bible declares that evil will not have the last word: God has seen, God remembers, God will act.
• Judgment is a hope on one condition: that it be just. The judge bears wounds. He loved his enemies, ate with sinners, wept over Jerusalem, and gave his life for the world. The harvest is not entrusted to impulsive servants, but to the Son of Man.
• The parable does not end on the weeds but on light: “Then the righteous will shine forth like the sun in the Kingdom of their Father” (Matthew 13:43), echoing Daniel 12:3. The Christian hope is not to flee the field, but to see God renew what evil has overrun.
• Your labor “is not in vain in the Lord” (1 Corinthians 15:58). Every time you forgive instead of taking revenge, protect a vulnerable person, or open your home to someone alone, you bear witness to the kingdom, because the harvest is coming.

8. What Kind of Plant Are You Becoming?

• The first question is not “can you identify the weeds?” but “what kind of plant are you?” Are you receiving the Word of the kingdom? Are you becoming like Jesus? Do your roots go deep into grace? Does your presence in the field bring nourishment, healing, and hope?
• First encouragement: trust the sower. The field is not beyond his reach, he knows what you are going through.
• Second encouragement: discern the enemy. Don’t blame God for evil. Don’t let those responsible escape accountability in the name of respect, and don’t let anyone dress sin in religious language. Look for faithfulness and character, not just results.
• Third encouragement, perhaps the hardest: resist premature judgment. Protect people, practice accountability, but leave the last word to Jesus.
• Fourth encouragement: live in the light of the harvest. The field is mixed, the enemy is active, the servants are limited, but the Son of Man is Lord. “May God help us never to believe that we have the right to write anyone off.”

Key Takeaways

• The kingdom begins with good seed: the sower has not stopped sowing, and the field still belongs to him.
• You have received the Word of the kingdom, and God has sown you in the world: your family, your work, your city are your field.
• The enemy works by imitation: the most dangerous evil looks like good. Discernment is based on fruit, not on suspicion.
• Patience is not passivity: the Church protects, corrects, and is accountable, but it does not pronounce the final separation.
• Judgment belongs to the Son of Man, the judge who bears wounds. He is the hope of the victims, and the righteous will shine like the sun.

Personal Application

1. Where are you looking most right now: at the weeds that worry you, or at the sower who keeps sowing?
2. In what place has God sown you this season (work, neighborhood, family), and how can you bring the presence of the kingdom there this week?
3. What counterfeit of the good may you have let grow in you: cowardice called wisdom, control called leadership, prejudice called discernment?
4. Is there a person you have inwardly “written off”? What would it mean, for them, to leave room for grace and repentance?
5. What quiet act of faithfulness (forgiving, protecting, welcoming) can you do today, knowing it will not be in vain in the Lord?

Frequently Asked Questions

What does the parable of the weeds mean in Matthew 13?

Jesus explains it himself: the one who sows the good seed is the Son of Man; the field is the world; the good seed is the children of the kingdom; the weeds are the children of the evil one; the enemy is the devil; the harvest is the end of the age. For Malcolm Duncan, the parable answers a question every disciple eventually asks: if the kingdom has come, why is there still so much evil?

Why does the master refuse to pull up the weeds right away?

Because in pulling up the weeds, the servants would uproot the wheat as well. This is not indifference to evil, it is wisdom about judgment. Malcolm Duncan makes clear that this does not permit tolerating abuse: the Church must protect the vulnerable and exercise discipline, but the final separation belongs to God alone.

Is the final judgment good news?

Yes, provided it is just. A gospel that never speaks of judgment has nothing left to say to the victims of war, abuse, or corruption. Judgment declares that evil will not have the last word. And the judge is Jesus, who loved his enemies, ate with sinners, and gave his life for the world.
