Luke 6:47 Commentary: Hear and Do

Luke 6:47 comes near the end of what is often called the Sermon on the Plain (Luke 6:17, 49). Jesus has just gathered a large crowd of disciples and others from Judea, Jerusalem, and the coastal regions. He has taught about blessings and woes (vv. 20, 26), love for enemies (vv. 27, 36), and warned against judging others (vv. 37, 42). The section leading into v. 47 uses the image of trees and fruit (vv. 43, 45) to emphasize that inner character produces outward action. Then in v. 46 Jesus directly challenges those who call him “Lord, Lord” but do not do what he says. That challenge sets up v. 47 as the counter, the kind of person who both hears and acts.

The culture of first-century Galilee placed high value on oral teaching. Rabbis had disciples who memorized their words. But Jesus insists that memorization is not enough; doing is essential. The promised “showing”, the parable of the house built on rock, draws on the experience of anyone building in a region of seasonal wadis (dry riverbeds that flood without warning during rains). A foundation that reaches down to bedrock was expensive but would survive a flash flood. For Luke’s audience, hearing Jesus and not doing would be like building a beautiful house directly on packed earth, fine until the water comes.

The immediate literary context reinforces this: vv. 48, 49 contrast two builders. One digs deep and lays a foundation on rock; the other builds directly on the ground. The flood tests both. Only the house built on rock stands. Jesus is saying that his words, heard and done, are that rock. The flood represents the crises of life and final judgment.

The supplied sources note no significant textual variants for Luke 6:47. The verse appears uniformly in the manuscript tradition. A few later manuscripts add minor clarifying phrases (e.g., the addition of “my” before “words” in some Byzantine texts), but these do not affect the meaning.

Luke 6:47 has been central to Christian teaching on discipleship from the earliest centuries. Early church fathers such as Clement of Alexandria and Origen cited the verse to warn against a mere intellectual faith that lacks obedience. In the medieval period, the verse was incorporated into monastic rules as a reminder that hearing must lead to doing, the Rule of St. Benedict echoes the same principle. During the Reformation, both Luther and Calvin used this passage to contrast faith that saves with faith that is dead (citing James 1:22 alongside it). The verse has been a staple of evangelical preaching on lordship, especially in the twentieth-century “Lordship Salvation” debates, where it was used to argue that true faith necessarily produces obedience. Across traditions, it remains a simple but searching test of authentic Christian life.

Three-point outline

1. Coming to Jesus, The opening participle, erchomenos, means coming to him as a disciple (Gill). This is the initial movement of faith, coming to Christ for rest and instruction (Matthew 11:28, 29).
2. Hearing his words, Akouōn is not passive listening but attentive, obedient hearing. It includes understanding and trusting what he says (Thayer’s definition: “to attend to, consider what is said”).
3. Doing them, Poiōn (present active participle) is ongoing action. Obedience is not a one-time decision but a lifetime pattern. Jesus shows that the one who does is like a house built on rock (v. 48).

Five-point outline

1. Jesus poses the diagnostic question: “Why do you call me ‘Lord, Lord’ and not do what I say?” (v. 46). The issue is lordship, not just information.
2. He answers with a universal invitation: “Everyone who comes to me”, no one is excluded. The word pas (“everyone”) opens the door to all.
3. He defines genuine discipleship with three verbs: coming, hearing, doing. All three are present tense, continuous action.
4. He promises to show plainly (hupodeixō, Clarke) what such a person is like, the parable that follows (vv. 48, 49) will make it visible.
5. The parable explains: only a life founded on Christ’s words, put into practice, can withstand the storms of life and judgment.

Illustration hooks

• Reading a manual vs. building the furniture. You can read the instructions cover to cover and still fail if you never pick up the screwdriver. Hearing without doing takes you nowhere.
• Building on sand. Many in your congregation know the difference between a structure with a real foundation and one that shifts every time the ground gets wet. The same is true for spiritual life built on good intentions alone.
• The phrase “Lord, Lord.” Imagine someone shouting “Boss, boss” every morning but never doing a single task. That’s the picture Jesus paints. Calling Jesus “Lord” is meant to change everything.

Questions your congregation is asking

• “If I struggle to obey, does that mean I’m not really saved?”
• “How can I tell the difference between hearing Jesus just for knowledge and hearing him in a way that changes my life?”
• “What do I do when I know what Jesus said but I don’t want to do it?”

Luke 6:47 is a verse that zeroes in on the gap between saying and doing. In the verses just before, Jesus confronts those who call him “Lord” but ignore his commands (v. 46). He uses the image of fruit trees to show that what comes out of us reveals what is really inside (v. 45). Then he describes the person who both hears and obeys. This verse is a mirror. It invites each of us to examine how we relate to Jesus’ words. Do we treat them as suggestions, or as the foundation of our lives?

Discussion questions

1. Read Luke 6:46, 47 together. What is the contrast Jesus sets up between v. 46 and v. 47?
2. The Greek present participles “coming,” “hearing,” and “doing” all describe ongoing action. Why do you think Jesus uses continuous tense instead of a one-time event?
3. Look at v. 45 just before: “Out of the abundance of the heart, his mouth speaks.” How does that verse help you understand what Jesus means by “does them” in v. 47?
4. Why does Jesus promise to “show” what the obedient person is like (v. 47) instead of just telling? What does that say about how we learn obedience?
5. Compare Luke 6:47 with Matthew 7:24. What is different about the wording? What does Luke’s version add to your understanding?
6. Think of a time when you knew the right thing to do from Scripture but struggled to do it. What made the difference between knowing and doing?
7. How would your life change if you took this verse as a filter for every decision? What practical step could your group take this week to be “doers” and not only hearers (James 1:22)?
