Luke 6:39 Commentary: Can the Blind Lead the Blind?

Luke presents this saying without specifying a particular incident, which prompts Calvin to note that “Christ may have spoken this parable more than once.” The verse stands as part of a collection of sayings in Luke’s “Sermon on the Plain” (Luke 6:20, 49), though several commentators, including Lange and JFB, observe that Matthew records essentially the same proverb in a different setting (Matthew 15:14, during a confrontation with the Pharisees over tradition). The proverb itself draws on common Jewish wisdom. A blind guide was a familiar image for a teacher who lacked true understanding; the Old Testament frequently denounces such leaders. Isaiah 9:16 warns, “For those who lead this people lead them astray; and those who are led by them are destroyed.” Isaiah 56:10 calls the watchmen of Israel “blind, they are all without knowledge.” By calling his words a “parable,” Luke uses the term in its broader sense, a vivid, proverbial comparison drawn from daily life. The “pit” (βόθυνος, bothunos) likely refers to a cistern or ditch, a common hazard in the Judean landscape. Historically, the Pharisees were widely regarded as guides for the people, yet Jesus repeatedly charges them with spiritual blindness. In this context, the parable becomes a sharp critique of hypocritical leadership and a warning to all who would claim authority without receiving light from God.

The supplied commentaries and lexical data note no significant textual variants for Luke 6:39. The verse is stable across the major manuscript traditions (Vaticanus, Sinaiticus, etc.). The Greek text reads consistently.

Early church writers, such as Clement of Alexandria, used this proverb to warn against heretical teachers who lacked true knowledge of God. During the Reformation, both Catholic and Protestant interpreters applied the verse to clerical leaders who, in their view, taught error. Matthew Henry and the Geneva Bible notes treat it as a general warning against hypocritical instruction. In modern preaching, the verse often appears in sermons on accountability and the dangers of following influencers without discernment. The saying has also been absorbed into common speech as the proverb “the blind leading the blind,” though its original force, pointing to impending disaster, is sometimes softened.

Three-point outline

1. The blind cannot lead. Jesus uses μήτι (mēti), expecting a firm “no.” Spiritual sight is essential for anyone who would guide others. Without it, teaching becomes folly and leadership becomes dangerous.
2. Both guide and follower share the fall. The interrogative οὐχί (ouchi) demands an affirmative: yes, both will fall into the pit. The leader’s blindness does not only harm the leader, it drags the follower down too. The pit is destruction, whether temporal ruin or eternal judgment.
3. Self-examination comes before instruction. In Luke’s ordering, this parable sits between the command not to judge (v.37) and the lesson on the speck and beam (vv.41, 42). The sequence is deliberate: you cannot help others see while you yourself are blind.

Five-point outline

1. Jesus speaks a parable. He uses a familiar proverb to lodge a truth deep in memory.
2. The rhetorical double punch. Two questions, two different expected answers: the first says “impossible,” the second says “inevitable.”
3. Identifying the blind guide. In Matthew 15:14 the target is the Pharisees. In Luke, the context of judging others (v.37) broadens the warning to any disciple who condemns while remaining blind to his own faults.
4. The pit as the end. The Greek verb ἐμπεσοῦνται (future indicative, “will fall in”) declares an outcome that is certain if the path is not changed.
5. Application for the church. Every teacher, parent, and leader stands under this warning. The solution is not to refuse to lead but to first receive sight from the true Light.

Illustration hooks

• A GPS that keeps saying “recalculating” because it has no satellite signal, the driver keeps turning but ends up lost, and the passenger shares the frustration.
• A person in a dark room trying to help someone else find a light switch by touch alone. Both grope, both bump into furniture.
• A coach who has never played the game, but insists on instructing players from a manual he barely understands.

Questions your congregation is asking

• “How do I know if I am spiritually blind without someone to show me?”
• “Does this mean I should never try to help someone else until I am perfect?”
• “Who are the blind guides today, and how do I avoid following them?”

This parable challenges us to inspect our own sight before we attempt to direct anyone else. Jesus places it immediately after a command not to judge, suggesting that the act of judging others often blinds us to our own condition. As you discuss, remember that the goal is not paralysis but honest self-examination before God.

Discussion questions

1. What does “blindness” mean in a spiritual sense? How does a person become blind according to Scripture?
2. Why does Jesus use two different Greek particles (μήτι and οὐχί) in the same verse? How does that affect the force of his question?
3. Read Matthew 15:14, where Jesus uses the same proverb about the Pharisees. How does that context differ from Luke’s, and what does it add to your understanding?
4. In what situations might a sincere Christian unknowingly act as a blind guide? How can we guard against this?
5. How does verse 40 (“A disciple is not above his teacher”) connect to the blind guide warning? What does it say about the outcome of following a blind leader?
6. Think of a time when you gave advice to someone while ignoring a significant struggle in your own life. What happened? What did you learn?
7. What practical steps can this group take to ensure that our teaching and counsel are guided by the light of Christ rather than our own blind spots?
