1 John 2:28-3:24: Are You a Son of the Devil?

About This Episode

There is an ancient battle between children of God and children of Satan that stretches back to the garden of Eden. And John uses this ancient battle to encourage a community under threat. Seth and David talk about what it means to be a child of God and why being righteous and loving one another is good news for people afraid, persecuted, and unsure if they belong to God.

Are You a Son of the Devil? — 1 John 2:28–3:24

Show Notes

David Bowden and Seth Stewart open this episode of the Spoken Gospel podcast by jumping into one of the most provocative questions in 1 John: How do you know if you belong to God or to Satan? The passage under discussion, 1 John 2:28–3:24, pushes into themes of assurance, righteousness, and identity that have been building throughout the letter. What follows is a rich exploration of what it means to be called a child of God — and what that identity looks like in the face of persecution, doubt, and the daily struggle to love well.

Confidence When Jesus Returns

The passage begins with a tender address — "little children" — which carries a double meaning. It is both a term of affection from a spiritual father to his congregation and a theological cue pointing to the reality of being born into God's family. This idea of being "born of God" is significant because it represents something new that John is describing in light of what Jesus has accomplished. While the Old Testament speaks of belonging to God's family, the language of being born of God signals a new creative act.

The stakes of this identity become clear in verse 28, where John urges his readers to abide in Jesus so that "when he appears, we may have confidence and not shrink from him in shame at his coming." Throughout 1 John, the language of Jesus' "appearing" has mostly referred to the incarnation — his first coming. But here, John pivots to the future, using the Greek word parousia, the term used almost exclusively in the New Testament for the second coming of Jesus. The two options on that day are confidence or shame. That framework echoes the Old Testament vision of the day of the Lord, where people either stand firm or beg the mountains to fall on them. John's encouragement is that those who are God's children need not fear that day, because when Jesus appears, they will be made like him (1 John 3:2). The reason for confidence is not personal merit — it is that God himself will complete the transformation he started.

This future hope is not escapism. It is meant to fuel present endurance. The New Testament consistently teaches that knowing Jesus is coming again does something to believers right now. It builds confidence for life in the present, not just in the age to come. And that matters especially because John's original audience was likely facing real physical danger — not just intellectual doubts about their faith, but the threat of imprisonment, persecution, and death under forces hostile to the Gospel.

Children of God and Children of the Devil

At the heart of this passage is a stark binary: there are children of God and children of the devil. The phrase "children of the devil" might sound like something out of a fantasy novel or a horror film, but John grounds it in the most ancient conflict in Scripture — the battle between the seed of the woman and the seed of the serpent, first announced in Genesis 3:15. This cosmic war finds its earliest human expression in the story of Cain and Abel, where a righteous son is murdered by his brother out of hatred for his obedience to God.

John is not introducing a new category. He is giving a new name to the same reality he has been describing throughout the letter. The antichrists who went out from the church, the false teachers undermining the community's faith — they are children of the devil in the same way the Pharisees were when Jesus called them that in John 8. To be a child of the devil is to stand on the wrong side of God's purposes, whether that opposition looks overtly violent or deceptively religious. The secessionists from the church are simply the latest expression of a Satanic pattern that has existed since the garden — a hatred of righteousness and an attempt to crush those who pursue it.

The word "lawlessness" in verse 4 deepens this picture dramatically. In English, "sin is lawlessness" can sound like a bland tautology — of course breaking the law is sinful. But in the Greek Old Testament (the Septuagint), the word anomia carries far more weight. It is used not only for human disobedience but for demonic forces, Satanic powers, and even as a title for the pagan god Belial. By the time John writes, anomia has become a word loaded with associations to the powers of darkness. So when John says "sin is lawlessness," he is not merely defining a word. He is saying that habitual sin is a demonically empowered reality — that to make a practice of sinning is to be under Satan's influence.

The Seed of God and the Practice of Righteousness

John introduces a striking metaphor to explain how transformation works in the life of a believer: God's seed is in us. This is not abstract theology. It is a picture of something organic and alive, planted by God himself, that grows over time. When someone trusts in Jesus, they do not receive an instantly mature faith. They receive a seed — and like any seed buried in soil, it takes time to sprout. A new believer might look at their life and think nothing has changed, but God's seed is already at work beneath the surface.

This is the theological reality traditionally called sanctification — the process of being made more like Jesus over time. The seed grows, and as it does, it bears fruit in the form of righteousness. The repeated phrase "everyone who" (the Greek word pas) appears seven times in this section, echoing the rhythms of creation. Just as God made all things good in seven days, he is building a new creation in his people — a new reality marked by righteousness and love rather than rebellion and hatred.

This growth is what John means when he says, "No one who abides in him keeps on sinning" (1 John 3:6). This is not a claim that believers never sin — John already addressed that in 1 John 1, where he said anyone who claims to be without sin is self-deceived. Rather, the idea is that a believer's controlling influence has changed. Before Jesus, the governing power over a person's life was the world, the flesh, and the devil. Capital-S Sin was a master that held people captive, preventing them from ever truly doing good on their own. But when Jesus appeared, he destroyed the devil's work (1 John 3:8) and broke Sin's enslaving power. Now, with God's Spirit as the new ruling presence, believers can do righteousness for the first time. Their intuitions shift. God's law is written on their hearts. The practice of righteousness is not a burden to earn favor — it is the natural fruit of a new nature.

Love as the Litmus Test

After discussing righteousness and sin in broad theological terms, John brings the conversation to ground level: "Whoever does not practice righteousness is not of God, nor is the one who does not love his brother" (1 John 3:10). All the cosmic language about God's seed, Satan's influence, and the children of the devil comes down to something profoundly concrete — how you treat other people.

John uses Cain and Abel as the archetypal illustration. Cain hated his brother because Abel's deeds were righteous, and that hatred led to the first murder in Scripture. The pattern repeats throughout history: those who pursue God's ways are hated by those who do not. But John flips the script by pointing to Jesus as the "anti-Cain." The Greek word for "he" in verse 16 — "by this we know love, that he laid down his life for us" — is ekeinos, which phonetically echoes the name Cain. Where Cain brought death into the world by killing his righteous brother, Jesus brought life into the world by dying for his unrighteous enemies. Where Cain's story is one of hatred leading to murder, Jesus' story is one of love leading to sacrifice.

This reframes what it means to love in the context of persecution. Loving your brother does not only mean loving fellow believers who are easy to love. In the Cain and Abel paradigm, the righteous one loves even the brother who hates him. This is what Jesus modeled — dying for those who put him on the cross. The persecuted have an opportunity the persecutors never have: to display the self-giving love of Jesus by loving those who would destroy them. John says this love — sacrificial, enemy-embracing, generous — is how "we know that we have passed out of death and into life" (1 John 3:14).

John then makes it impossibly practical in verse 17: if you see someone in material need and you have the means to help but refuse, how can the love of God be in you? Love is not merely a feeling or a theological concept. It is action — giving your resources, your time, your comfort for the sake of another.

When Your Heart Condemns You

One of the most pastorally rich moments in the passage comes in verses 19–20: "By this we shall know that we are of the truth and reassure our heart before him; for whenever our heart condemns us, God is greater than our hearts, and he knows everything." This is not a blanket reassurance that guilt does not matter. It is a reminder that when believers feel the sting of their own lack of generosity or love, they can look to a God who is more generous than they could ever be. God knows every deficiency in our hearts, and yet he has already shown his generosity toward us through Jesus. The proper response to a condemning heart is not to wallow in guilt or to frantically do good works to earn favor. It is to look at God's greater generosity and let it propel us toward love.

This is where John's audience becomes critically important. He is not writing to people who are trying to earn their way into God's family by performing acts of charity. He is writing to believers who are beaten down by persecution, who wonder whether they can endure, who need someone to remind them that their changed lives are proof that God's seed is growing in them. John's message to them is tender and direct: Have you been generous? Have you loved your enemies? Have you prayed for your persecutors? Then you are a child of God — because children of the devil do not act that way.

Confidence to Stand Before God

The passage closes with a breathtaking invitation to confidence. John writes, "If our heart does not condemn us, we have confidence before God" (1 John 3:21). He then summarizes the whole of the law and the prophets in one command: "Believe in the name of his Son, Jesus, and love one another, just as he commanded us" (1 John 3:23). The assurance John offers is not rooted in perfection but in identity. If you trust Jesus and you love others, you are abiding in God — and God is abiding in you.

This challenges a deeply ingrained instinct in many believers — the reflex to always identify primarily as a sinner in need of forgiveness. While repentance is essential, John is pushing his readers to see themselves as something more: sons and daughters of God, with new natures and new capacities for righteousness. Mature faith is not only about confessing sin, though confession remains vital. It is also about recognizing the fruit that God's Spirit is producing and allowing that recognition to build confidence rather than guilt. John invites believers to look at the ways Jesus is changing them — less anger, more generosity, deeper love — and to say, without pride but with genuine joy, "God's seed is bearing fruit in me." That is not arrogance. That is the Gospel doing what the Gospel does.
