Building a Fruit Stand
Matthew 7:15–20 (ESV): 15 “Beware of false prophets, who come to you in sheep’s clothing but inwardly are ravenous wolves. 16 You will recognize them by their fruits. Are grapes gathered from thornbushes, or figs from thistles? 17 So, every healthy tree bears good fruit, but the diseased tree bears bad fruit. 18 A healthy tree cannot bear bad fruit, nor can a diseased tree bear good fruit. 19 Every tree that does not bear good fruit is cut down and thrown into the fire. 20 Thus you will recognize them by their fruits.
Luke 6:43–45 (NIV): 43 “No good tree bears bad fruit, nor does a bad tree bear good fruit. 44 Each tree is recognized by its own fruit. People do not pick figs from thornbushes, or grapes from briers. 45 A good man brings good things out of the good stored up in his heart, and an evil man brings evil things out of the evil stored up in his heart. For the mouth speaks what the heart is full of.
Matthew 7:15-20: Sermon Setting: Sermon on the Mount (on a mountain)
Primary Target: False prophets and external deceivers
Key Metaphor: Wolves in sheep’s clothing
Tone: Warning of fiery divine judgment
Key Conclusion: “By their fruits you will know them.”
Luke 6:43-45: Sermon Setting: Sermon on the Plain (on a level place)
Primary Target: Every individual disciple’s inner heart
Key Metaphor: Treasures stored in the heart
Tone: Wisdom teaching for self-examination
Key Conclusion: “Out of the abundance of the heart the mouth speaks.”
1. Outward Warning vs. Inward Examination
- Matthew emphasizes protecting the community. Jesus warns about “false prophets” who appear harmless but are inwardly dangerous. The fruit test gives the church a practical way to recognize harmful leaders.
- Luke emphasizes self-examination. Luke omits false prophets and wolves, speaking directly to the disciples instead. His point is less about judging others and more about examining one’s own spiritual condition.
2. The Mechanics of the Metaphor (The “Heart”)
- Matthew connects fruit with final destiny. Matthew includes verse 19: “Every tree that does not bear good fruit is cut down and thrown into the fire.” This places the teaching in the context of accountability and coming judgment.
- Luke connects fruit with speech. Luke replaces the judgment warning with verse 45: “A good man brings good things out of the good stored up in his heart… For the mouth speaks what the heart is full of.” In Luke, the clearest “fruit” is what a person says in daily life.
3. Targeted Audience Nuances
- Matthew writes for Jewish Christians who would recognize the language of prophets and Old Testament warnings about false leaders.
- Luke writes for a broader Gentile audience. He removes specifically Jewish institutional language, such as “prophet,” to present a universal lesson about character, morality, and integrity.
Then the story of two builders:
| Feature | Matthew 7:24–27 | Luke 6:46–49 |
| Introductory Rebuke | Condemns empty charismatic works (“Lord, Lord, did we not prophesy…?”) | Condemns basic ethical disobedience (“Why do you call me ‘Lord, Lord,’ and do not do what I say?”) |
| The Wise Builder | Builds his house on the rock | Digs deep and lays the foundation on rock |
| The Foolish Builder | Builds his house on sand | Builds a house on the ground without a foundation |
| The Nature of the Crisis | Rain, floods, and winds blow against the house | A torrent breaks and strikes against the house |
| The Final Note | “And great was its fall.” | “Its destruction was complete.” |
