Passage under comment1 John 3:11–13
11¶ For this is the message that ye heard from the beginning, that we should love one another.
12Not as Cain, who was of that wicked one, and slew his brother. And wherefore slew he him? Because his own works were evil, and his brother's righteous.
13Marvel not, my brethren, if the world hate you.
The apostle, having intimated that one mark of the devil's children is hatred of the brethren, takes occasion thence,
I.To recommend fraternal Christian love, and that from the excellence, or antiquity, or primariness of the injunction relating thereto:
And this is the message (the errand or charge) which you heard from the beginning (this came among the principal parts of practical Christianity), that we should love one another, Jo1 3:11. We should love the Lord Jesus, and value his love, and consequently love all the objects of it, and thereupon all our brethren in Christ.
II.To dissuade from what is contrary thereto, all ill-will towards the brethren, and that by the example of Cain.
His envy and malignity should deter us from harbouring the like passion, and that upon these accounts: - 1. It showed that he was as the first-born of the serpent's seed; even he, the eldest son of the first man, was of the wicked one. He imitated and resembled the first wicked one, the devil. 2. His ill-will had no restraint; it proceeded so far as to contrive and accomplish murder, and that of a near relation, and that in the beginning of the world, when there were but few to replenish it. He slew his brother, Jo1 3:12. Sin, indulged, knows no bound. And, 3. It proceeded so far, and had in it so much of the devil, that he murdered his brother for religion's sake. He was vexed with the superiority of Abel's service, and envied him the favour and acceptance he had with God. And for these he martyred his brother. And wherefore slew he him? Because his own works were evil, and his brother's righteous, Jo1 3:12. Ill-will will teach us to hate and revenge what we should admire and imitate. And then,
III.To infer that it is no wonder that good men are so served now:
Marvel not, my brethren, if the world hate you, Jo1 3:13. The serpentine nature still continues in the world. The great serpent himself reigns as the God of this world. Wonder not then that the serpentine world hates and hisses at you who belong to that seed of the woman that is to bruise the serpent's head.

We have had the commandment to love one another from the beginning, so that we should not fall into evil as Cain did, who murdered his brother.
"Not as Cain, who was of that wicked one, and slew his brother. And wherefore slew he him? Because his own works were evil, and his brother's righteous." Therefore, where envy is, brotherly love cannot be. Mark, my beloved. He that envieth, loveth not. The sin of the devil is in that man; because the devil through envy cast man down. For he fell, and envied him that stood. He did not wish to cast man down that he himself might stand, but only that he might not fall alone. Hold fast in your mind from this that he has subjoined, that envy cannot exist in charity. Thou hast it openly, when charity was praised, "Charity envieth not." There was no charity in Cain; and had there been no charity in Abel, God would not have accepted his sacrifice. For when they had both offered, the one of the fruits of the earth, the other of the offspring of the flock; what think ye, brethren, that God slighted the fruits of the earth, and loved the offspring of the flock? God had not regard to the hands, but saw in the heart: and whom He saw offer with charity, to his sacrifice He had respect; whom He saw offer with envy, from his sacrifice He turned away His eyes. By the good works, then, of Abel, he means only charity: by the evil works of Cain he means only his hatred of his brother. It was not enough that he hated his brother and envied his good works; because he would not imitate, he would kill. And hence it appeared that he was a child of the devil, and hence also that the other was God's righteous one. Hence then are men discerned, my brethren. Let no man mark the tongue, but the deeds and the heart. If any do not good for his brethren, he shews what he has in him. By temptations are men proved.
Cain became unrighteous and turned into the very first person who killed a member of his family, thereby teaching human nature the way of murder.
Not as Cain, who was of the evil one, etc. He explains how Cain was of the evil one because he himself had evil deeds. Therefore, where there is envy, brotherly love cannot exist; but the sin of the evil one, that is, the devil, is in such a heart, for the devil also cast out man through envy. Therefore, the righteous deeds of Abel signify nothing but charity. The evil deeds of Cain signify nothing but fraternal hatred. It is not enough that he hates his brother and envies good deeds (thus). Hence, men are distinguished. Let no one heed words, but deeds. Why, if he does not do good for his brothers, shows what he has within himself? Men are tested by temptations.
For this is the message that you heard from the beginning, that we should love one another. Not as Cain, who was of the wicked one and murdered his brother. And why did he murder him? Because his works were evil and his brother's was righteous. Do not marvel, my brethren, if the world hates you. We know that we have passed from death to life because we love the brethren. He who does not love his brother abides in death. Whoever hates his brother is a murderer, and you know that no murderer has eternal life abiding in him.
Therefore, having explained these things, he repeats after many points made in between, love for one's neighbor, as if he had treated all that was in between for its sake, since love is also the fullness of everything (Rom. 13:10), and he says:
"He who does not love his brother is not of God." But against this, this member is also placed: He is not of God, saying this: For if he who does righteousness is born of God, it follows that he who is therefore born loves his brothers; but he who does not do righteousness, because he does not do it by hating his brothers, is not of God, not in any other way except that he is not born of him. And how he is not of him is shown by saying: "for this is the message that you heard from the beginning." (see Lev. 19:24) What this announcement is, we have already said, both naturally received and through teaching; but also by the legal command to love one's neighbor, as the Lord's command says: "A new commandment I give to you, that you love one another." (Jn. 13:34) The natural command regarding those of the same kind and condition also urges one to do this. Therefore, since there are so many such commands in accordance with the Lord's declaration, whoever keeps and does His word has eternal life and has passed from death to life. (Jn. 5:24)
Therefore, let us love our brothers, taking nothing harmful to imitate: for example, if we are hated by the world, let us not also hate our brothers: but let the word of the Lord be more effective in us. For whoever hates his brother is not only cast out from eternal life, but is also a murderer. For it necessarily follows that if he is a murderer, he has no eternal life. Behold Cain, John says, for he too, having hated his brother, murdered him, although he was his brother. But because Cain had evil works, he was the son of the Devil: whereas Abel, by doing righteous works, was called the son of God: the Devil is opposed to God, and evil works to good ones: therefore, Cain, being contrary to his brother, murdered him. Thus, indeed, the course of the discourse was consequent, but blessed John changed the order, always serving what was more pressing. For it was pressing, because he had mentioned the Devil and those who had been adopted by him due to their wicked actions, so as to propose him as an example who, from the beginning of the world, escaped as the wicked son through evil works.

Summary
First John 3:12 presents the stark example of Cain's murder of Abel as a powerful illustration of the antithesis between the children of God and the children of the devil. John uses this ancient narrative to underscore the destructive nature of hatred and envy, revealing that such evil actions stem from an allegiance to "that wicked one" and stand in direct opposition to the righteous love that characterizes true believers. The verse serves as a sober warning, linking internal malice with outward violence, and contrasting the unacceptable "evil works" of Cain with the divinely approved "righteous" deeds of Abel.
Context
Literary Context
This verse is strategically placed within a pivotal section of 1 John (1 John 3:10-18) where the Apostle John sharply distinguishes between those who belong to God and those who belong to the devil. Following the foundational assertion in 1 John 3:10 that "whoever does not practice righteousness is not of God, nor is he who does not love his brother," John immediately provides Cain as the quintessential negative example. The preceding verse, 1 John 3:11, explicitly states, "For this is the message that you heard from the beginning, that we should love one another." Cain's fratricide is thus presented as the ultimate violation of this core commandment, serving as a chilling antithesis to the love that should define God's children. It highlights that hatred, even when unexpressed in violence, is fundamentally antithetical to the divine nature and spiritual lineage of a believer.
Historical & Cultural Context
The story of Cain and Abel, found in Genesis 4, was a foundational narrative within Jewish tradition, deeply familiar to John's original audience. It represented the first act of murder in human history, born out of jealousy and a rejection of God's favor. For the early Christian communities, who often faced internal strife and external persecution, the warning against hatred and division was particularly pertinent. The cultural context of the Roman Empire, with its emphasis on honor and shame, and the prevalence of various philosophical and religious systems, meant that John's clear distinction between "children of God" and "children of the devil" provided a stark moral and spiritual framework. The concept of "works" (actions) as indicators of one's true character and allegiance was also a widely understood principle, both in Jewish thought and the broader Greco-Roman world, making Cain's "evil works" a universally recognizable symbol of depravity.
Key Themes
The verse significantly contributes to several key themes in 1 John. Firstly, it elaborates on the theme of Spiritual Lineage and Affiliation, emphasizing that one's actions, particularly their capacity for love or hatred, reveal their true spiritual parentage. Cain's being "of that wicked one" (1 John 3:12) underscores that profound evil is not merely a human failing but has a demonic origin or influence, echoing Jesus' words about the devil being a murderer from the beginning in John 8:44. Secondly, it develops the theme of Love as the Defining Mark of Discipleship by presenting hatred as its antithesis. The murder of Abel, fueled by envy over Abel's righteous offering (Genesis 4:4-5), demonstrates how hatred, left unchecked, culminates in destructive actions. This aligns with Jesus' teaching in the Sermon on the Mount that anger and hatred in the heart are tantamount to murder in God's eyes (Matthew 5:21-22). Finally, the verse reinforces the theme of Righteousness vs. Wickedness, highlighting that "works" are not just external acts but manifestations of an internal spiritual state, revealing whether one walks in light or darkness.
Exposition and Analysis
Key Word Analysis
From a derivative of πόνος, meaning "hurtful" or "evil." In this context, it refers to the devil, emphasizing the malevolent, destructive influence behind Cain's actions. It denotes evil not just in character but in its harmful effect and influence, contrasting with inherent character (κακός). Cain's being "of that wicked one" signifies a spiritual alignment with the forces of darkness, whose very nature is to cause harm and destruction.
From a primary (but obsolete) verb meaning "to work," referring to toil, effort, or occupation. By implication, it signifies an act or deed. Here, "works" are the outward manifestations of an inward disposition, revealing the true spiritual alignment of an individual. Cain's "evil works" were the visible fruit of his inner malevolence, while Abel's "righteous" works were the expression of his faith and obedience.
From δίκη, meaning "equitable in character or act." By implication, it means innocent or holy, either absolutely or relatively. Abel's works were "righteous" because they were in accordance with God's will and acceptable to Him, contrasting sharply with Cain's unacceptable actions and revealing God's favor upon Abel's obedient heart.
Verse Breakdown
"Not as Cain"
This phrase immediately introduces a negative paradigm, setting Cain up as the antithesis to the love and righteousness that should characterize believers. It warns against imitating his example.
"who was of that wicked one"
This clause reveals the spiritual origin of Cain's malevolence. His actions were not merely human failings but stemmed from a spiritual allegiance to Satan, the "wicked one," demonstrating the devil's influence in generating hatred and violence.
"and slew his brother"
This is the direct, violent consequence of Cain's wicked nature and spiritual alignment. It highlights the ultimate, devastating outcome of unchecked hatred and envy.
"And wherefore slew he him?"
This rhetorical question draws the reader's attention to the underlying motive, prompting a deeper reflection on the spiritual roots of such an atrocious act. It implies that the reason is crucial for understanding the nature of evil.
"Because his own works were evil, and his brother's righteous"
This provides the explicit answer to the rhetorical question, pinpointing the core reason for the murder. Cain's evil deeds and disposition clashed with Abel's righteous character and actions, leading to a murderous envy fueled by spiritual darkness.
Literary Devices
John employs several potent literary devices in this verse. Antithesis is central, contrasting Cain with Abel, evil works with righteous works, and implicitly, the "children of the devil" with the "children of God." This stark opposition highlights the fundamental difference between those who walk in darkness and those who walk in light. The phrase "Not as Cain" serves as an Exemplum, using a well-known biblical figure as a cautionary tale to illustrate the dangers of hatred and unrighteousness. Furthermore, the Rhetorical Question, "And wherefore slew he him?", engages the reader directly, prompting them to consider the profound spiritual reasons behind Cain's actions rather than merely focusing on the physical act of murder. This device emphasizes the moral and theological implications of the narrative.
Theological and Thematic Connections
The theological significance of 1 John 3:12 lies in its profound articulation of the spiritual conflict between light and darkness, love and hatred, and righteousness and sin. It asserts that actions are not merely external behaviors but are deeply indicative of one's spiritual allegiance. Cain's act of fratricide, driven by envy of Abel's divinely accepted righteousness, becomes a timeless archetype of the world's hatred for those who walk in God's truth. This verse underscores the New Testament emphasis that hatred in the heart is equivalent to murder in God's sight, revealing the spiritual root of violence and discord. It calls believers to a radical self-examination, urging them to cultivate genuine love as the defining mark of their new spiritual birth, a love that stands in stark contrast to the destructive spirit of "that wicked one."
Reflection and Application
First John 3:12 serves as a profound mirror, inviting us to look deeply into the hidden corners of our own hearts. It challenges the common misconception that sin is only about outward actions, revealing that the seeds of hatred, envy, and malice, if left unchecked, can lead to spiritual death and destructive behavior, mirroring Cain's tragic path. The verse compels us to confront any resentment or animosity we might harbor, especially towards those who seem to be more favored or righteous in God's eyes. Our spiritual lineage is not merely a theological concept but a lived reality, demonstrated by our capacity to love our brothers and sisters in Christ. To be "of God" means to actively pursue righteousness and to embody the self-sacrificial love that defines Christ. Therefore, cultivating a heart free from envy, quick to forgive, and eager to uplift others becomes a vital expression of our identity as children of God, standing in direct opposition to the spirit of Cain.
Questions for Reflection
FAQ
What does "was of that wicked one" mean in this context?
The phrase "was of that wicked one" (Greek: ek tou ponērou) means that Cain's actions and character were derived from, or belonged to, the devil. It signifies a spiritual origin or allegiance. John is not suggesting that Cain was literally the devil's son, but rather that his nature and deeds were aligned with the devil's malevolent character and purposes. The devil is characterized as a murderer and a liar from the beginning (John 8:44), and Cain's act of fratricide perfectly embodies this destructive, anti-God spirit. This highlights that unrighteousness and hatred are not merely human flaws but are rooted in a spiritual opposition to God.
Christ-Centered Fulfillment
The shadow of Cain's hatred and murder in 1 John 3:12 finds its ultimate antithesis and fulfillment in the person and work of Jesus Christ. Cain's evil works led to the slaying of his righteous brother, driven by envy and a rejection of God's favor. In stark contrast, Jesus, the perfectly righteous Son of God, willingly laid down His life for His unrighteous "brothers" and "sisters," motivated by perfect love (John 15:13). While Cain's act brought death and condemnation, Christ's sacrifice brings life and justification to all who believe. The world's hatred, exemplified by Cain, ultimately culminated in the crucifixion of the Son of God (John 15:18-20). Yet, through His death and resurrection, Christ conquered "that wicked one" (Hebrews 2:14) and established a new spiritual lineage, enabling believers to become children of God through faith in Him (John 1:12). Thus, the call to love one another in 1 John 3:11 is not merely a moral imperative but a Christ-centered command, empowering us to reflect His self-giving love rather than succumbing to the destructive hatred of Cain.
