Understanding Matthew 7:15–27—Why the Wolves and the Workers of Lawlessness Are Not the Same
Introduction
Matthew 7:15–27 contains some of the most solemn warnings Jesus ever gave. These verses form His final appeal at the conclusion of the Sermon on the Mount. In this passage, Jesus speaks of wolves in sheep’s clothing, good and bad trees, workers of lawlessness, and wise and foolish builders.
While these images are often discussed separately, these warnings should not be viewed as isolated sayings detached from the Sermon on the Mount. Rather, they form the Lord’s concluding application of His Kingdom teaching, showing how the principles He has taught are to be discerned, lived out, and ultimately evaluated. As such, they should form a single, continuous thread within Jesus’ larger Kingdom teaching.
Before filtering these verses through later traditions or theological systems, we must first ask: What does Jesus actually say?
At the outset, Jesus describes a group as “ravenous wolves” disguised in sheep’s clothing (vv. 15–16). He later refers to another group who call Him “Lord, Lord” and appeal to past ministry done in His name—prophesying, casting out demons, and performing miracles (vv. 21–22). Finally, He concludes with the parable of the two builders who both hear His words, but only one puts them into practice.
Because these different groups are described in entirely distinct terms, we should allow Jesus’ own words to define each one and reveal their connections. As we will see, the wolves and the workers of lawlessness are not the same group—and the parable of the two builders provides the decisive clue.
The purpose of this study, then, is to examine the passage carefully so we can better understand who the workers of lawlessness are, why they are rejected, and how the closing parable resolves the question.
I. Wolves in Sheep’s Clothing (vv. 15–16)
We begin with the first warning Jesus issues in this section. He commands:
“Beware of false prophets, who come to you in sheep’s clothing, but inwardly are ravenous wolves.”
Notice the specific language Jesus chooses. He identifies them as false prophets and ravenous wolves. A wolf is not a sheep, nor can it become one. The disguise is therefore an unnatural, intentional deception designed to appear harmless, trustworthy, and acceptable among the flock. Their purpose is not to feed the sheep but to devour them.
By calling them false prophets, Jesus centers His concern on deceptive spiritual guides who present themselves as legitimate leaders. The danger they pose is twofold: through false teaching they lead people away from the truth, and through their influence they take advantage of those who gather around them. This imagery sets these guides in direct opposition to the Good Shepherd and the welfare of His flock. Elsewhere in His Kingdom teaching, Jesus explicitly attributes the sowing of such counterfeit elements to the devil (Matthew 13:28, 39). Here, however, the focus remains on the immediate, practical danger they pose to the flock—hence the Lord’s emphatic warning: “Beware.”
Jesus immediately adds this test:
“Do men gather grapes from thornbushes or figs from thistles?”
The implied answer is obvious: No. A thornbush cannot produce grapes, nor a thistle figs.
At this point, Jesus is teaching discernment based on fruit. Disciples must judge spiritual guides not by outward appearance or impressive self-presentation, but by what their lives and ministries ultimately produce. Do the sheep under their care receive life and grow in the truth of God, or are they led astray and harmed? Jesus declared, “I came that they may have life and have it abundantly” (John 10:10). The disguise may fool the careless for a season, but the fruit eventually exposes the true nature of the tree—and the one who bears it.
This choice of imagery is entirely deliberate. A ravenous wolf may disguise itself in sheep’s clothing, but it can never change its fundamental nature. Eventually the distinction becomes evident. Those most vulnerable to deception are often not those who have never heard the truth, but those who hear it yet fail to respond in obedience (see, for example, the Parable of the Soils in Matthew 13 and Hebrews 3:7–19). Throughout Jesus’ Kingdom teaching, spiritual discernment is closely tied to obedience to God’s Word. The careless are easily fooled by appearances, but the discerning disciple learns to judge according to the clear standards Christ Himself provides.
In our own context—whether in local churches, online teaching, street ministry, or personal Bible study—whose “fruit” are we actually examining? Appearances, or lasting transformation in the lives of the sheep?
II. From Wolves to Trees (Matthew 7:17–20)
This focus on fruit leads Jesus to expand the principle beyond false prophets alone. He now shifts the imagery from ravenous wolves in sheep’s clothing to trees and their fruit — a transition that is both deliberate and significant.
Having issued the urgent warning about deceptive guides, the Lord broadens His teaching into a clear, universal Kingdom principle:
“Every good tree bears good fruit, but a bad tree bears bad fruit. A good tree cannot bear bad fruit, nor can a bad tree bear good fruit.” (vv. 17–18)
The emphasis moves from outward disguise to the deeper reality of nature and consistent fruitfulness. “Good” and “bad” here describe the inner character and spiritual condition that eventually become evident through the fruit produced. Jesus is concerned less with labeling people than with revealing their true state. Just as a wolf cannot become a sheep, a bad tree cannot produce good fruit, no matter how promising its appearance may be for a season.
Jesus states this with sobering finality:
“Every tree that does not bear good fruit is cut down and thrown into the fire. Thus you will recognize them by their fruits.” (vv. 19–20)
This section builds directly on the wolf warning while extending it. The same standard of discernment now applies more broadly: we must look past appearances and evaluate the actual fruit produced in the lives and ministries of those who claim to speak or act for God. Good trees produce fruit that leads to life and obedience. Diseased trees, even if they appear religious or impressive, ultimately yield harm, confusion, or spiritual barrenness.
This principle of fruit-testing prepares the ground for the even more startling warning that follows in verses 21–23. Not everyone who appears fruitful — or even performs impressive works in Jesus’ name — will enter the Kingdom of heaven.
While trees in nature reproduce according to their kind, Jesus applies this physical reality directly to our spiritual lives. His concern is the spiritual condition revealed by fruit, not biological classification. This imagery echoes rich Old Testament themes of Israel as God’s vineyard and the prophetic calls to produce fruit worthy of repentance (Isaiah 5:1–7; Matthew 3:8–10). Within the Sermon on the Mount, this serves not merely as a warning about others but also as an invitation to honest self-examination. True fruit is measured by alignment with the King’s words — righteousness, mercy, purity of heart, and wholehearted obedience (Matthew 5–7).
In our churches, ministries, and personal lives, this raises a vital question: Are we producing good fruit that will endure the final test, or merely impressive foliage that will not survive?
III. Who Are the Workers of Lawlessness? (Matthew 7:21–23)
This principle of fruit-testing reaches its most sobering climax in the next warning. Jesus declares:
“Not everyone who says to Me, ‘Lord, Lord,’ shall enter the kingdom of heaven, but he who does the will of My Father in heaven.” (v. 21)
Notice carefully whom Jesus describes. These are not pagans, atheists, or open enemies of Christ. They sincerely call Him “Lord” and point to impressive ministry accomplishments done in His name:
“Many will say to Me in that day, ‘Lord, Lord, did we not prophesy in Your name, cast out demons in Your name, and do many mighty works in Your name?’” (v. 22)
Their defense rests entirely on what they had done. Yet Jesus’ verdict is devastating:
“And then I will declare to them, ‘I never knew you; depart from Me, you workers of lawlessness!’” (v. 23)
Significantly, Jesus does not deny the works they claim. He does not say, “You never prophesied” or “You never cast out demons.” Instead, He directs attention to their actual condition: lawlessness — a life no longer ordered by the will and Word of the Father.
The Greek phrase “workers of lawlessness” (literally “those practicing lawlessness,” ἐργαζόμενοι τὴν ἀνομίαν) uses a present participle, emphasizing an ongoing pattern of conduct rather than isolated failures or past accomplishments.
An important distinction emerges here. The wolves in sheep’s clothing are identified by what they are — false prophets and ravenous wolves in disguise.
The workers of lawlessness, however, are identified by what they practice. The emphasis has moved from outward disguise, to fruit, to ongoing conduct.
Jesus Himself draws the decisive contrast: Not everyone who says “Lord, Lord” will enter the Kingdom, but “he who does the will of My Father in heaven.” Contextually, calling Him “Lord, Lord” and doing the Father’s will belong together. The tragedy is that these individuals have departed from continued obedience to the Father’s will. Like branches that no longer abide in the True Vine (John 15), their lawless practices reveal that they are no longer living in submission to God.
True belonging to Christ is evidenced not by verbal profession or spectacular ministry alone, but by ongoing obedience — the very obedience that continually produces the good fruit by which people are recognized (vv. 16–20).
This warning echoes the lesson of the cursed fig tree: outward appearance, religious profession, and visible activity are not enough. The Lord looks for fruit. Leaves without fruit and profession without obedience reveal the same tragic condition. The workers of lawlessness may point to impressive accomplishments, yet their continuing pattern of life shows they are not aligned with the will of the Father.
The Old Testament prophet Balaam offers a sobering illustration. He received genuine revelations from God and spoke powerful prophetic words, yet Scripture remembers him for leading God’s people into compromise and sin (Numbers 31:16; 2 Peter 2:15; Jude 11; Revelation 2:14). Spiritual gifts and impressive activity are never substitutes for obedience.
In our own day — when many claim powerful ministries, large platforms, or dramatic spiritual experiences — this passage calls us to honest self-examination: Are we doing the will of the Father, or merely doing many things in His name?
IV. Why Were They Called Workers of Lawlessness?
What, then, is the “lawlessness” Jesus condemns? In this context, the answer is clear. Jesus has just declared that entrance into the kingdom belongs to “he who does the will of My Father in heaven” (v. 21), and He immediately contrasts those who “hear these sayings of Mine and do them” with those who only hear (vv. 24–27). Within the Sermon on the Mount, lawlessness is therefore the refusal to submit to the King’s revealed will.
That is why Jesus’ verdict is so severe. These individuals are characterized by a pattern of disobedience. Their confession (“Lord, Lord”) is orthodox in form and their ministry claims impressive — prophecy, exorcisms, and mighty works — yet none of these can substitute for obedience. Jesus does not deny their works; He rejects the life they have lived before Him.
The broader biblical witness clarifies what such obedience looks like. Jesus Himself summarizes the Law and the Prophets in wholehearted love for God and neighbor (Matthew 22:37–40). Paul teaches that love is the fulfillment of the law (Romans 13:10), and that even the most dramatic gifts are empty without it: “If I have the gift of prophecy… but have not love, I am nothing” (1 Corinthians 13:1–3). While Matthew 7 focuses on doing the Father’s will, the larger Scripture shows that this will is expressed in a life shaped by love, humility, and faithful submission to God.
This is why the title “workers of lawlessness” is so searching. They worked much, but not in obedience. They served publicly, but not in conformity to the Father’s will. Their appeal was a résumé of accomplishments rather than a life of faithful discipleship. In the end, Jesus exposes the tragedy of religious labor without relational knowledge: “I never knew you; depart from Me.”
V. The Solemn Verdict: “I Never Knew You”
The phrase “I never knew you” is among the most solemn statements Jesus ever uttered. It is not merely a criticism of actions but a verdict concerning a person’s relational standing before Him.
In the immediate context, Jesus places the primary emphasis on lawlessness — those characterized by an ongoing practice of disobedience. Within the Sermon on the Mount, doing the Father’s will finds its practical expression in hearing Jesus’ words and putting them into practice (Matthew 7:24–27) — the very point Jesus develops in the parable of the wise and foolish builders that immediately follows.
VI. The Wise Builder: Jesus’ Final Answer (Matthew 7:24–27)
Jesus concludes this solemn series of warnings with a clear “therefore.” This is the practical application of everything He has taught in the Sermon on the Mount:
“Therefore whoever hears these sayings of Mine, and does them, I will liken him to a wise man who built his house on the rock.” (v. 24)
The final contrast is no longer between wolves and sheep, nor between those who say “Lord, Lord” and those who do not. The contrast is now between two hearers of the same words. Both hear Jesus’ teaching. Only one puts it into practice.
The wise builder hears Christ’s words and continues to put them into practice from the laying of the foundation to the completion of the house. He builds on the rock with perseverance, counting the cost and remaining committed to the Master’s design through every stage of construction. When the rains descend, the floods come, and the winds blow, his house stands firm because it is founded on the rock (v. 25).
The foolish builder also hears the words but does not act on them. He builds on sand. When the storm arrives, his house falls, and great is its fall (vv. 26–27).
The difference is not in knowledge or even in hearing. The difference is obedience—the very obedience that produces good fruit and guards against the ongoing practice of lawlessness.
As Jesus taught elsewhere:
“Which of you, intending to build a tower, does not sit down first and count the cost, whether he has enough to finish it?” (Luke 14:28)
A house—and a life—is not built in a day. True discipleship requires steadfast commitment, perseverance through trials, and wholehearted determination to finish according to the Lord’s words.
This final parable ties the entire passage together. It reveals the practical difference between the wise disciple and the worker of lawlessness. The wise builder not only hears the King’s words but continues to build his entire life upon them.
When we look at the immediate context of the Sermon on the Mount, it becomes clear that “these sayings of Mine” encompass all that Jesus has taught—from the Beatitudes to His commands concerning righteousness, purity, love, prayer, forgiveness, trust, and obedience. The wise builder does not selectively obey; he builds on the whole counsel of Christ. The storm represents both the inevitable tests of life and the final judgment. Only a life founded upon an obedient response to Jesus’ words will endure.
Conclusion
Jesus’ solemn warning in Matthew 7:15–27 unfolds as a single, continuous thread: from ravenous wolves in sheep’s clothing, to trees and their fruit, to the workers of lawlessness, and finally to the wise and foolish builders.
The wolves deceive.
The fruit reveals.
To the workers of lawlessness, Jesus pronounces:
“I never knew you; depart from Me.”
The wise builder stands firm.
The Lord’s final emphasis is not on what people claim to have done in His name, nor on impressive spiritual activity. His emphasis rests on whether we hear His words and do them.
The wise builder builds upon “these sayings of Mine”—the whole counsel of Christ revealed throughout the Sermon on the Mount.
In the end, the most important question is not:
“Have we heard Christ’s words?”
Nor even:
“Have we done impressive works in His name?”
The decisive question is:
Are we building our lives upon the words of Christ — or upon the shifting sands of profession, giftedness, and outward appearance? May the Lord grant us grace to be wise builders—those who not only hear the King’s words but put them into practice with wholehearted, persevering obedience. In doing so, we will bear lasting fruit, abide in the True Vine, and stand firm when the storm comes—all to the glory of God. Amen.
