Luke 6:40 Meaning: Becoming Like Your Teacher

A disciple is not above his teacher, but everyone when he is fully trained will be like his teacher.

Meaning in one sentence

Jesus' verse about discipleship: what it means to be fully trained and become like your teacher, not above them.

Luke New Testament Greek

Context

Jesus is in the middle of teaching a crowd on a level place, often called the Sermon on the Plain. He has just finished speaking about mercy, not judging, and generous giving. Then He asks a sharp question: “Can the blind guide the blind? Won’t they both fall into a pit?” This one about the disciple and the teacher comes right after. It connects two ideas. First, whoever leads must see clearly. Second, the one being led will end up where the leader is. Matthew places the same saying in a scene where Jesus warns about false teachers. Here in Luke, the verse works as a hinge between the parable of the blind guide and the instructions that follow about seeing the speck in your brother’s eye. The point is practical: you become like the person you follow.

Key Words

Two Greek words anchor this verse. The first is mathētēs, meaning “a learner” or “pupil.” It is the word for disciple. A disciple is not someone who has arrived, but someone who stays in the posture of learning. The second is the word behind “fully trained.” That verb is katartizō. It originally meant to mend a broken net, set a dislocated bone, or restore something to its proper place. When the Gospels use it for mending nets, you picture the careful work of pulling torn strands back together. When Paul uses it for restoring a brother caught in sin, you see the tenderness of bringing someone back to wholeness. So being “fully trained” is not just knowing more facts. It is being remade, repaired, put right. The verse promises that when this mending is complete, the disciple will be like the teacher. Not better, not above, but shaped into the same character.

How Christians Read This Verse

Christians have read this verse in two ways that overlap. Some, like John Calvin, emphasize the word katērtismenos as meaning “fit” or “suitable,” not perfect in the absolute sense. For Calvin, the point is about resemblance: the disciple is meant to be formed after the master’s example. Others, including Adam Clarke and the Geneva Bible, take “perfect” or “thoroughly instructed” more directly. Clarke writes that the one who is “thoroughly instructed in Divine things” will be like Christ: “holy, harmless, undefiled.” The Cambridge Bible notes the verse was a favorite of John’s. Across traditions, there is agreement that the goal is not to surpass the teacher but to be conformed to him. What differs is how much weight falls on the process of training versus the final state of maturity.

A common misunderstanding

Some readers think this verse means you can never know more than your teacher or grow beyond them in any way. In fact, the point is about moral and spiritual formation, not information. A student may gain knowledge their teacher did not have. But the question Jesus is asking is deeper: whose character are you absorbing? The verse warns that you will reflect your master’s heart. It is not a ceiling on learning, but a call to choose whom you follow.

Living This Out

Think about the people whose words shape your decisions this week. A podcast you listen to each morning. A friend whose advice you trust. A social media voice you scroll past without thinking. All of them are teachers in some way. You do not aim to be better than them, you naturally become like them. That is why Jesus says this. He wants you to stay close to Him, to let His teaching mend what is broken in you. This week, before you act on someone else’s opinion, ask yourself: would following this voice make me more like Jesus or less? And when you stumble, do not push away from Him. That is part of the training.

Main takeaway: The goal of following Jesus is not to surpass Him but to be shaped into His likeness, fully restored and whole.

For Families

For ages 5, 8

When you learn from someone, you start to act like them. Jesus says a student is not greater than the teacher. The best thing is to be like your teacher.

For ages 9, 12

Think about the people you watch and listen to most. Without noticing, you will start to think like them, talk like them, and act like them. That is what this verse means. Jesus wants you to learn from Him more than anyone else. Not so you can be better than Him, but so you can be like Him. That takes time and practice. He will keep teaching you until you are whole.

Questions People Ask

What does 'fully trained' mean in the Greek language of this verse?

The Greek word is katērtismenos, from the verb katartizō. It means to mend, repair, put in order, or restore. It was used for mending fishing nets and for setting a dislocated bone. So being 'fully trained' is not just learning lessons but being made whole again, restored to the shape God intends.

Does Luke 6:40 mean a disciple can never know more than their teacher?

No. The verse is about moral and spiritual character, not about knowledge or skill. A student can certainly learn facts their teacher did not know. But Jesus says the disciple will become like the teacher in heart and action. The point is about whose example you are following.

How is this verse connected to the blind leading the blind in verse 39?

The connection is immediate. If a blind person leads another blind person, both fall into a pit. Jesus then says a disciple is not above the teacher. Together they mean: if you follow a teacher who cannot see, you will end up where they are, in the ditch. But if you follow the true Teacher, you will be formed into His likeness.

Some translations say 'perfect' instead of 'fully trained.' Which is better?

Both can work, but 'fully trained' or 'perfected' (as a process) captures the Greek more clearly. The word katērtismenos is a participle describing someone who has been mended or put right. It does not mean sinless perfection in an instant. It means being gradually restored until you match the teacher’s example.

What does this verse teach about discipleship and humility?

It teaches that discipleship is not about climbing above your teacher. The goal is not to be more famous, wiser, or holier than Jesus. The goal is to be like Him. That requires humility and trust. You let Him set the pace and you follow. Becoming like Jesus is already more than enough.
