Commentary on Galatians 4 verses 17–18
The apostle is still carrying on the same design as in the foregoing verse, which was, to convince the Galatians of their sin and folly in departing from the truth of the gospel: having just before been expostulating with them about the change of their behaviour towards him who endeavoured to establish them in it, he here gives them the character of those false teachers who made it their business to draw them away from it, which if they would attend to, they might soon see how little reason they had to hearken to them: whatever opinion they might have of them, he tells them they were designing men, who were aiming to set up themselves, and who, under their specious pretences, were more consulting their own interest than theirs: "They zealously affect you," says he; "they show a mighty respect for you, and pretend a great deal of affection to you, but not well; they do it not with any good design, they are not sincere and upright in it, for they would exclude you, that you might affect them. That which they are chiefly aiming at is to engage your affections to them; and, in order to this, they are doing all they can to draw off your affections from me and from the truth, that so they may engross you to themselves." This, he assures them, was their design, and therefore they must needs be very unwise in hearkening to them. Note, 1. There may appear to be a great deal of zeal where yet there is but little truth and sincerity. 2. It is the usual way of seducers to insinuate themselves into people's affections, and by that means to draw them into their opinions. 3. Whatever pretences such may make, they have usually more regard to their own interest than that of others, and will not stick at ruining the reputation of others, if by that means they can raise their own. On this occasion the apostle gives us that excellent rule which we have, Gal 4:18, It is good to be zealously affected always in a good thing. What our translation renders in a good man, and so consider the apostle as pointing to himself; this sense, they think, is favoured both by the preceding context and also by the words immediately following, and not only when I am present with you, which may be as if he had said, "Time was when you were zealously affected towards me; you once took me for a good man, and have now no reason to think otherwise of me; surely then it would become you to show the same regard to me, now that I am absent from you, which you did when I was present with you." But, if we adhere to our own translation, the apostle here furnishes us with a very good rule to direct and regulate us in the exercise of our zeal: there are two things which to this purpose he more especially recommends to us: - (1.) That it be exercised only upon that which is good; for zeal is then only good when it is in a good thing: those who are zealously affected to that which is evil will thereby only to do so much the more hurt. And, (2.) That herein it be constant and steady: it is good to be zealous always in a good thing; not for a time only, or now and then, like the heat of an ague-fit, but, like the natural heat of the body, constant. Happy would it be for the church of Christ if this rule were better observed among Christians!
Since emulate signifies two things—one when someone emulates what he finds pleasing because it is good and another when people are emulators because they feel envy—these people, he says, emulate you in a bad way, by which he means that they are imitators through envy.… When he adds the phrase “so that you may emulate them” [meaning] “that you may follow them,” he has thus used the double sense of emulation in different places, since emulation is imitation, and especially when it is also directed to what is good.… [He continues: ] “Emulate therefore better gifts—not those of Jewish law, which are not gifts and are not better; but emulate those things which are good and better gifts. That is, whatever belongs to faith and love, emulate that with regard to Christ and follow it. It is always good to emulate better things. Emulation as such is not good, but the emulation of better things is always good, and not only when I am present.”
It is a wholesome emulation which leads to an imitation of virtue, but an evil one, which seduces from virtue him who is in the right path. And this is the object of those persons, who would deprive you of perfect knowledge, and impart to you that which is mutilated and spurious, and this for no other purpose than that they may occupy the rank of teachers, and degrade you, who now stand higher than themselves, to the position of disciples. For this is the meaning of the words "that ye may seek them." But I, says he, desire the reverse, that ye may become a model for them, and a pattern of a higher perfection: a thing which actually happened when I was present with you. Wherefore he adds,
(Verse 17, 18.) They imitate you, but not in a good way: rather, they want to exclude you so that you may imitate them. But always imitate the good in what is good, and not only when I am present with you. Those imitate well who, when they see that others have gratitude, gifts, virtues, desire to possess those themselves: and they strive to imitate their faith, life, and industry through which they have earned those things, so that they may also attain those things which are worthy of good emulation. Of these things, the Apostle also says: Envy spiritual gifts, but especially that you may prophesy. And further: So also you, since you are eager for spiritual gifts, seek to excel for the edification of the church. And again: Therefore, brethren, desire earnestly to prophesy, and do not forbid speaking in tongues. But those who envy do not do so well, for they do not desire to be better themselves in order to imitate those who are worthy of envy, but rather they want to make them worse and backwards with perverse envy. For example, let it be said: a Christian is someone who reads Moses and the prophets; he knows that everything in the shadow and the image preceded that people; but that the scriptures were written for us on whom the ends of the ages have come. He understands circumcision not so much of the foreskin, but of the ears and the heart. He has risen with Christ: he seeks the things that are above. He is freed from the burden and slavery of the Law, of not touching, not tasting, not handling, which commands: if someone wants to persuade him with the words of the Scriptures, that he should receive them not through a figure of speech, but as they are written in a literal sense, so that he may become a Jew openly, not secretly, he imitates him not well: but he quickly rushes to pull him back as he moves towards greater things; so that he may rather imitate him who goes backward: or indeed he does not advance him much further."+ "\n" +"Liberated from the burden and slavery of the Law, of not touching, not tasting, not handling, which commanded, being able to read the scriptures in their literal sense, an individual who is a Christian demonstrates the true meaning of these commandments. They understand that the Old Testament accounts serve as types and foreshadows of Christ and that the observance of these commandments no longer holds the same significance as it did for the Jewish people. They are no longer bound by the strict regulations of the Law but are free to seek the things above and live according to the spirit of the New Covenant. Therefore he speaks to the Galatians who had been led astray by the advocates of the Law, urging them to imitate the advocates of the Law, when rather the Galatians should have imitated them. For it is natural for the greater to be made from the lesser, not the lesser from the greater, and he says: 'Imitate what is good in what is good,' that is, do not imitate the advocates of Jewish observance, but imitate those things which are good. For just as someone who imitates someone else in riches, power, or dignity, not only imitates good things, but also imitates things that should be avoided; so likewise, you in turn, imitate what is good in what is good: seeking spiritual things more than carnal things; so that you may not teach them to be Jews, but to be Christians. But do this always, so that you may be able to reach the end of a good work with a persevering step. For I emulated good in you when I was with you, but after I left, you lost everything that I had handed over to you, from a secure station and a trustworthy port, and you were carried away again in the high waves. And it is not surprising that, with the Apostle departing, the Galatians were changed from a chosen vessel and one in which Christ the Lord spoke: for even now we see the same thing happening in the churches. For whenever a doctor happens in the Church, adorned with eloquence of speech and with a virtuous life, who, like some sort of spur, incites those who hear him to virtues, we see all people hasten, fervor, and run about concerning almsgiving, fasting, chastity, receiving the poor, burials, and other similar things. But when he has departed, they gradually wither away, and with food removed, they grow thin, pale, weak, and death follows all those things which were previously flourishing. Therefore, because the harvest is plentiful, but the laborers are few (Matthew 9:37), let us pray to the Lord of the harvest to send laborers to reap the ears of the Christian people, which are prepared for the future wheat in the Church, to gather and carry them into the barns so that they may not perish. This is about that zeal and perverse emulation, of which it is also said elsewhere: Do not emulate the wicked (Psalm 37:1), and here: They emulate you, but not for good. But we find another kind of zeal, with which the sons of Jacob were zealous for their brother Joseph (Gen. XXXVII seqq.); and Mary and Aaron were zealous for their friend the Lord Moses (Num. XII). Neither Joseph nor Moses were incited to zeal in order to be better than others, but because they were grieved that they were better. This kind of zeal is akin to envy. It would be long if I wished to enumerate all the kinds of zeal, whether good or bad, found in the treasure of the Scriptures. We read of the righteous zeal of Phinehas (Num. XXV), Elijah (III Kings XIX), Matthias (I Macc. II), and the Apostle Judas (but not the traitor), who received the name Zealot for his outstanding virtue of zeal (Acts I). But we also read of the evil zeal, like that of Cain towards Abel (Gen. IV), and others towards one another. And there is the zeal of a man, of whom it is written: 'And if the spirit of jealousy comes upon him' (Num. V). Perhaps this is the middle kind of zeal, which cannot be taken on either the good or the bad side; rather, it is called zealotry between the two. Otherwise: Seeing that those who were from circumcision, the Galatians from the Gentiles, were abundantly filled with the virtues of the Holy Spirit, but indeed did not speak in tongues, did not have the gifts of healings; did not have the gift of prophecy, they eagerly desired to incite them with the stings of zeal, to transfer them to the burdens of the Law, so that they would begin to become like them.
He says this with reference to those evil teachers. “For seeing your conspicuous faith,” he says, “they are grieved and all try by every means to rob you of those goods and subject you to their own authority.” For that is what he means by writing “that you may emulate them.”

SUMMARY
In Galatians 4:17, the Apostle Paul exposes the insidious tactics of false teachers, often identified as Judaizers, who were actively seeking to sway the Galatian believers. He reveals that their intense interest and zealous pursuit of the Galatians were not for the spiritual good of the church, but rather for their own manipulative ends. These deceivers aimed to isolate the Galatians from Paul and the true gospel of grace, thereby bringing them under their own legalistic authority and system, ultimately for their personal gain and prestige.
CONTEXT
EXPOSITION AND ANALYSIS
Key Word Analysis
Verse Breakdown
Literary Devices
Paul employs several literary devices to powerfully convey his message in Galatians 4:17. Antithesis is central, contrasting the false teachers' "zeal" that is "not well" with Paul's own genuine, parental affection and zeal for the Galatians' true spiritual formation (implied by his concern throughout the chapter). There is also a strong sense of Irony in the false teachers' actions: they display "zeal" (a quality often associated with positive spiritual fervor) but use it for destructive, manipulative purposes. Furthermore, the verse demonstrates Parallelism in its structure, setting up a clear cause-and-effect or means-to-an-end relationship: their zealous pursuit and exclusionary tactics are directly aimed at achieving the goal of the Galatians' affection for them. This highlights the self-centered nature of their ministry compared to Paul's Christ-centered one.
THEOLOGICAL AND THEMATIC CONNECTIONS
Galatians 4:17 serves as a profound theological warning against spiritual manipulation and self-serving ministry. It underscores that outward displays of zeal or religious fervor do not automatically equate to pure motives or sound doctrine. True Christian leadership and teaching are characterized by selflessness, a genuine desire for the spiritual freedom and maturity of others, and an unwavering commitment to the truth of the gospel, rather than seeking personal gain or control. The verse implicitly contrasts the false teachers' desire to bring people under their own system with God's desire to bring people into a liberating relationship with Himself through Christ, free from the burden of legalistic performance.
REFLECTION AND APPLICATION
Galatians 4:17 offers timeless wisdom for believers navigating the complexities of spiritual communities today. It calls for a profound discernment of motives, reminding us that not every passionate or seemingly "spiritual" leader or group operates from a place of genuine love and truth. We must look beyond outward appearances and evaluate teachings and actions against the plumb line of Scripture, asking whether they lead to freedom in Christ or to a new form of bondage. This verse also serves as a potent warning against spiritual exclusivity and manipulation. Any group or teacher that seeks to isolate followers from other believers, to undermine healthy relationships, or to demand unquestioning allegiance to themselves, rather than to Christ, should raise immediate red flags. Our ultimate allegiance must be to Jesus Christ alone, and our spiritual growth should foster greater liberty, love, and unity within the broader body of Christ, not division or dependency on human systems.
Questions for Reflection
FAQ
What does Paul mean by "they zealously affect you, but not well"?
Answer: Paul is describing the intense, passionate, and persistent efforts of the false teachers (Judaizers) to win over the Galatian believers. The Greek word zēlóō (zealously affect) implies a strong desire, even a competitive or envious pursuit. However, Paul immediately qualifies this by adding "but not well," using the Greek kalōs, meaning "properly" or "for good." This indicates that while their zeal was evident, their motives were corrupt, their methods manipulative, and their ultimate goal was not the spiritual benefit of the Galatians or the glory of Christ, but rather their own self-aggrandizement and control. They were passionate, but for the wrong reasons and with harmful intentions, seeking to bring the Galatians under a legalistic system rather than into the freedom of the gospel.
Who are "they" in Galatians 4:17, and what was their ultimate goal?
Answer: "They" refers to the false teachers, primarily Judaizers, who were troubling the Galatian churches. These individuals were Jewish Christians who insisted that Gentile believers needed to observe the Mosaic Law, particularly circumcision, in addition to faith in Christ for salvation or spiritual completeness. Their ultimate goal, as revealed in the phrase "that ye might affect them," was to redirect the Galatians' allegiance from Paul and the true gospel of grace to themselves and their legalistic teachings. They sought to gain followers, prestige, and control, thereby building their own influence and authority within the Christian community, rather than genuinely serving Christ and His church. This self-serving ambition stands in stark contrast to Paul's desire for the Galatians to be conformed to Christ (Galatians 4:19).
CHRIST-CENTERED FULFILLMENT
Galatians 4:17, while exposing the deceptive nature of false teachers, implicitly points to Christ as the ultimate standard of true spiritual affection and the source of genuine inclusion. Unlike the false teachers who sought to "exclude" the Galatians from the freedom of the gospel to bring them under their own influence, Christ's mission was one of radical inclusion. He came not to establish a new legalistic system, but to fulfill the Law (Matthew 5:17) and offer a perfect righteousness through faith (Romans 3:21-26). The "zeal" of the false teachers was self-serving, but Christ's zeal was entirely for His Father's glory and the salvation of humanity, culminating in His selfless sacrifice on the cross (John 2:17). He did not seek to "affect" people for His own gain, but to draw them into a liberating relationship with God, making them children of God by adoption (Galatians 4:4-7). Thus, this verse, by highlighting the perversion of human zeal and the manipulation of exclusion, magnifies the pure, inclusive, and liberating work of Christ, who truly affects us "well" by bringing us into perfect fellowship with God, not through human effort, but through His finished work.
