1 John 4:7–12 So That We Might Live Through Him

Introduction

There are few phrases in modern religion more common than the phrase born again. People use it often, but many do not stop to think about what it actually means. In Scripture, being born again is not a slogan, a religious label, or a description of emotional enthusiasm. It is the work of God by which a sinner is given new life. That new life does not remain hidden. It changes a person. It affects the heart, the mind, the desires, and the way that person relates to others.

That is exactly where the Apostle John takes us in 1 John 4:7–12. After warning the church about false prophets and false teaching, John turns to the visible evidence that someone truly knows God. He does not point first to gifted speech, religious confidence, or outward success. He points to love. But this is not the kind of love our world casually speaks about. This is not sentimental affection, empty tolerance, or a warm feeling detached from truth. John is speaking about a love that comes from God, is defined by God, and is produced in those who have been born of God.

That means this passage is not merely about private spirituality. John is writing to believers gathered together as the people of God. He wants them to understand that new birth has both a personal and a corporate reality. Yes, each sinner must personally be reconciled to God through Jesus Christ. But no one is born again into isolation. We are brought into the family of God, joined to the body of Christ, and made part of a people who now display the effects of His saving work.

This passage shows us three truths. First, love is the defining fruit of the children of God. Second, the love of God is most clearly seen in the sending of His Son to save sinners. Third, the church becomes the visible display of that saving love in a dark world. John wants believers to know that the God no one has seen is not absent. His work is visible in the lives of those He has redeemed. And that is why this passage matters so much. The love of God is not only something we speak about. It is something that must be seen among us.

The Defining Fruit of the Children of God (1 John 4:7–8)

The Apostle John begins this section with a direct command to the church: “Beloved, let us love one another” (1 John 4:7). He is speaking to believers, to a gathered people, to those who profess to know the Lord. But John does not leave love as a bare command hanging in the air. He immediately tells us where this love comes from: “for love is from God” (1 John 4:7). That means the kind of love John is speaking about is not simply natural kindness, agreeable personality, or outward politeness. It is something deeper. It is something produced by God Himself.

This is where John introduces us to the reality that is often described in our society as being born again. Jesus had already taught Nicodemus, “unless one is born again he cannot see the kingdom of God” (John 3:3). He went on to say, “unless one is born of water and the Spirit, he cannot enter the kingdom of God” (John 3:5), and then made the distinction plain: “That which is born of the flesh is flesh, and that which is born of the Spirit is spirit” (John 3:6). In other words, Christianity is not merely a cleaned up version of natural man. It is not a better behaved flesh. It is not a moral upgrade. It is the work of God by His Spirit giving life where there was none.

John now shows us one of the clear results of that new birth. “Whoever loves has been born of God and knows God” (1 John 4:7). He is not saying that love causes a person to be saved. He is saying that love is one of the defining fruits that grows from a life that has already been changed by God. Jesus taught the necessity of the new birth. John is now showing the byproduct of that new birth. When God gives life, He also produces evidence of that life.

This is why the promise of the new covenant matters so much here. Long before John wrote this letter, God had already promised through Ezekiel, “I will sprinkle clean water on you, and you shall be clean from all your uncleannesses” and, “I will give you a new heart, and a new spirit I will put within you” (Ezekiel 36:25–26). He also said, “I will put my Spirit within you, and cause you to walk in my statutes” (Ezekiel 36:27). The kind of love John is speaking about is the fruit of that promised work. It is not the natural trait of the carnal man. It is the result of a heart of stone being replaced with a heart of flesh. It is the result of the Spirit of God dwelling in a person and producing what the flesh never could.

That means love must be understood in visible and practical terms. It is not enough to speak about love as an invisible feeling or a vague religious idea. Paul gives us a clear picture of what love looks like in real life: “Love is patient and kind, love does not envy or boast, it is not arrogant or rude. It does not insist on its own way, it is not irritable or resentful, it does not rejoice at wrongdoing, but rejoices with the truth. Love bears all things, believes all things, hopes all things, endures all things” (1 Corinthians 13:4–7). That kind of love is not produced by fallen flesh. It is the visible expression of the new life God gives.

But Scripture does not leave us to think that these qualities are produced by our own strength. Paul also tells us, “the fruit of the Spirit is love, joy, peace, patience, kindness, goodness, faithfulness, gentleness, self control” (Galatians 5:22–23). That means the love believers are called to display toward one another is not merely a moral standard to imitate by sheer effort. It is fruit the Spirit of God produces in those He indwells. The command to love is not disconnected from the power to love. God commands what His Spirit produces in His people. So when John says that those who are born of God love, that truth is reinforced here. The love shown in the life of a believer is a direct reflection of the Spirit of God at work within them.

The same is true in the Beatitudes. When Jesus describes those who are blessed by God, He speaks of the poor in spirit, those who mourn, the meek, those who hunger and thirst for righteousness, the merciful, the pure in heart, the peacemakers, and those persecuted for righteousness’ sake (Matthew 5:2–10). These are not random personality traits. These are the qualities that flow from a heart changed by grace. They are not the marks of the natural man left to himself. They are the characteristics of one who has been born from above.

This is important for us as a church to understand. New birth is personal, but it is not private in the sense of isolation. God saves individual sinners, but He does not save them to themselves. He brings them into His family, joins them to His people, and teaches them to love those who share the same mercy. That is part of why John’s command is given in this way. He is not merely saying that believers should become more pleasant people in general. He is saying that those who have been born of God will show the evidence of that life in the way they love one another.

John also gives the negative side of the truth: “Anyone who does not love does not know God” (1 John 4:8). That is a serious statement. He is not describing the believer who is struggling, immature, or needing correction. He is describing a settled pattern of lovelessness. A person who can continually live in contempt, bitterness, cruelty, or indifference toward the people of God while still claiming to know God has no comfort from this text. John does not soften the issue. If love is the defining fruit of the children of God, then lovelessness is not a small flaw. It is a warning sign.

And John tells us why this is so serious: “because God is love” (1 John 4:8). That does not mean love is whatever we want it to mean. It means that God Himself defines it. His character is its source. His nature is its standard. So when He gives new life to sinners, His work begins to show itself in them. The church should be able to see that fruit growing in the lives of those whom God has made His own.

For our church, this means we should not think of love as an optional quality or as a secondary issue. It is one of the clearest evidences that God has truly worked in us. Where there is new birth, there will be new fruit. Where God has given a new heart, there will be new affection. And where people truly know God, that knowledge will not remain trapped in private claims. It will be seen in the visible and practical love they show to one another.

The Demonstration of God’s Love (1 John 4:9–10)

After telling us that love is the defining fruit of those who have been born of God, John now shows us how the love of God has been made known. He does not leave love to human imagination. He does not allow us to define it by emotion, preference, or worldly success. He brings us to the center of the gospel and says, “In this the love of God was made manifest among us, that God sent his only Son into the world, so that we might live through him” (1 John 4:9). Then he presses further: “In this is love, not that we have loved God but that he loved us and sent his Son to be the propitiation for our sins” (1 John 4:10).

This is the heart of the matter. The love of God is not chiefly known by earthly comfort, outward success, or the material things that people often associate with blessing. It is most clearly and fully revealed in the sending of the Son. If we want to know what divine love looks like, we must not begin with our circumstances. We must begin with Jesus Christ, crucified for sinners.

John says that God sent His Son into the world “so that we might live through him” (1 John 4:9). That means our greatest problem was not a lack of direction, purpose, or encouragement. Our greatest problem was death. We were spiritually dead, unable to bring ourselves to life, unable to reconcile ourselves to God, unable to remove the guilt that stood against us. This is why the sending of Christ is such a display of love. God did not send His Son merely to improve us, inspire us, or assist us. He sent Him so that dead sinners might live.

This is the same truth Jesus declared when He said, “For God so loved the world, that he gave his only Son, that whoever believes in him should not perish but have eternal life” (John 3:16). Had God not provided this way, there would be no alternative path to peace with Him. There would only be condemnation. That is why the love of God must never be measured first by the temporary things of this life. The great evidence of His love is that He made a way for sinners who deserved judgment to receive life instead.

John also tells us what kind of love this is. “In this is love, not that we have loved God but that he loved us” (1 John 4:10). The order matters. God’s love did not begin as a response to our goodness, devotion, or worthiness. He did not look upon us and find us moving toward Him in faithfulness. His love moved toward those who were not loving Him at all. As Paul writes, “God shows his love for us in that while we were still sinners, Christ died for us” (Romans 5:8). The demonstration of God’s love is not that He rewarded the righteous, but that He gave His Son for the guilty.

This should humble us. There was nothing in us that could have obligated God to act on our behalf. He was under no requirement to save. He was not forced to restore what we had ruined. Yet the provision of salvation through faith in Christ stands as a display of mercy that should shake us at the deepest level. We stood opposed to a righteous and all powerful God. We pursued sin, loved idols, and dishonored the One who made us. Yet instead of immediate wrath, God gave mercy. Instead of leaving us to perish, He sent His Son.

Paul says in Ephesians that even “when we were dead in our trespasses,” God “made us alive together with Christ, by grace you have been saved” (Ephesians 2:5). He tells the Colossians that they were once “alienated and hostile in mind, doing evil deeds,” but have now been reconciled “in his body of flesh by his death” in order to be presented “holy and blameless and above reproach before him” (Colossians 1:21–22). This is what the love of God accomplished. It moved toward enemies. It reconciled the guilty. It gave life to the dead.

John uses a word in verse 10 that guards the gospel from being softened into sentiment. He says that the Son was sent “to be the propitiation for our sins” (1 John 4:10). This means that Christ did not merely sympathize with sinners. He did not simply set an example of sacrifice. He stood in our place and dealt with the wrath our sins deserved. He bore judgment so that judgment would not fall on those who trust in Him. This is why the cross is the clearest demonstration of love. Love did not ignore sin. Love provided the righteous answer to sin through the death of the Son.

This is why the Christian cannot point to riches, power, fame, comfort, influence, or any other earthly advantage as the central proof of God’s favor. God may provide earthly blessings according to His wisdom. He has given many good gifts to His people, and He still does. But those things are not the foundation of our confidence. The truest mark of divine love is that Christ was given for sinners. The clearest evidence of mercy is that the Son of God hung on a tree for sins that were not His own. Had He not done so, we would still stand condemned.

Paul says it plainly: “Christ Jesus came into the world to save sinners” (1 Timothy 1:15). That is the message John is pressing into the church. If we want to understand love rightly, we must look to the reconciling death of Christ. If we want to know whether God has been merciful, we must not begin by examining our possessions, comfort, or earthly circumstances. We must begin at the cross. There, the love of God is not vaguely suggested. It is clearly demonstrated.

For our church, this matters deeply. We live in a world that constantly redefines love and often measures the goodness of God by temporary outcomes. But John will not allow us to do that. He fixes our eyes on the Son sent into the world, the life given through Him, and the propitiation accomplished by His death. That is where the love of God is seen most clearly. And if that is how God has loved us, then that love must shape the way we understand our salvation, our worship, and our life together as His people.

The Display of God’s Work of Salvation (1 John 4:11–12)

After showing us the defining fruit of the children of God and the demonstration of God’s love in the sending of His Son, John now presses the truth into the life of the church. He writes, “Beloved, if God so loved us, we also ought to love one another” (1 John 4:11). This is not a suggestion for especially mature believers. It is not an optional extra for Christians who want to go deeper. It is the necessary conclusion that flows from the gospel itself. If God has loved us in this way, then those who have received that love are now obligated to show it.

John’s language is important. He says, “if God so loved us.” He does not mean uncertainty, as if perhaps God loved us and perhaps He did not. He means, since this is true, since God has loved us in such a great and costly way, the result must follow. The love of God is not meant to stop with us. It is meant to bear fruit among us. Those who have received mercy should not be merciless. Those who have been forgiven should not be unforgiving. Those who have been loved by God through Christ should not live in settled coldness toward those who have received that same love.

This becomes even more important when we remember what kind of people we were when God loved us. Through the person of Christ and the gospel delivered to us by the apostles, we know that God redeems sinners who repent and believe in Jesus Christ. He loved us not when we were righteous, but when we were in need of mercy. He gave life and salvation to those who had no claim upon His favor. If that is true, how can we justify treating with contempt those upon whom God has poured out that same grace?

This is where the doctrine of the new birth must be understood in its full setting. Being born again is personal, but it is not isolated. God reconciles individual sinners to Himself, but He does not save them into spiritual independence. He brings them into His family and joins them to His people. Peter writes that God “has caused us to be born again to a living hope through the resurrection of Jesus Christ from the dead,” and that this new life includes “an inheritance that is imperishable, undefiled, and unfading, kept in heaven for you” (1 Peter 1:3–4). The one who is born again has not merely received a private experience. He has received a living hope, a secured inheritance, and a place among the people of God.

That is why Peter can also say, “as you come to him, a living stone rejected by men but in the sight of God chosen and precious, you yourselves like living stones are being built up as a spiritual house” (1 Peter 2:4–5). The image matters. God is not gathering loose stones and scattering them in different directions. He is building something. He is forming a people together. He is making a spiritual house, a holy priesthood, a people who belong to Him. Later Peter says it even more directly: “Once you were not a people, but now you are God’s people, once you had not received mercy, but now you have received mercy” (1 Peter 2:10). That is not merely personal language. That is corporate language. God has made a people out of those who once had no place before Him.

This is why love in the church is not superficial. It is not courtesy alone. It is not a matter of mere personality. We were not saved to ourselves. We were brought into the same body. We now share the same standing before God because of the same Savior. God has not placed one believer in the category of associate and another in the category of stranger. He has made us sons and daughters, fellow heirs with Christ, joined together by grace. So when John says, “we also ought to love one another” (1 John 4:11), he is not calling for vague friendliness. He is calling for the visible expression of the reality God has created among His people.

Paul says the same in Ephesians: “For through him we both have access in one Spirit to the Father” (Ephesians 2:18). Because of Christ, those who once stood outside are now “fellow citizens with the saints and members of the household of God” (Ephesians 2:19). He goes on to say that the whole structure is “being joined together” and “grows into a holy temple in the Lord,” and that believers are “being built together into a dwelling place for God by the Spirit” (Ephesians 2:21–22). That helps us understand John’s words in verse 12. The church is not merely a gathering of people who happen to share similar beliefs. The church is the place where God is dwelling by His Spirit among a people He has redeemed through Christ.

That is why verse 12 is so striking: “No one has ever seen God, if we love one another, God abides in us and his love is perfected in us” (1 John 4:12). At first, the statement seems almost unexpected. Why does John suddenly remind us that no one has seen God? He does it to make a crucial point. God is invisible, but His work is not. His saving power is not hidden. His mercy is not abstract. His presence is made evident in the life of the church as His people love one another. The church becomes the visible display of God’s work of salvation in the world.

John is not saying that the church replaces Christ as the revelation of God. Christ alone is the full and final revelation of the Father. But John is saying that the God no one has seen is truly abiding in His people, and the evidence of that abiding is seen in the love produced among them. His love is “perfected in us,” meaning it reaches its intended expression in the life of the redeemed community. The love shown at the cross now bears visible fruit in the body of Christ.

This matters deeply for the witness of the church. The church is the display of God’s mercy and forgiveness toward sinners through Christ. When the world sees a people who have been forgiven learning to forgive, a people who have received mercy learning to show mercy, and a people who have been reconciled to God learning to love one another, it sees the visible evidence of a God who saves. The invisible God makes His saving work visible through the redeemed community He has formed in Christ.

That also means lovelessness in the church is not a small matter. A bitter church obscures the mercy it claims to preach. A cruel church contradicts the message it confesses. A divided church hides the beauty of the salvation it says it has received. But when the church loves one another as those who have been loved by God, the reality of His saving work is put on display.

For our church, this is a serious call. We are not merely preserving religious activity. We are not simply gathering to maintain tradition. We are meant to be a visible testimony that God has saved sinners through the death and resurrection of Jesus Christ. His mercy, forgiveness, and reconciling love should not only be spoken from the pulpit. They should be seen in the life of the people who gather in His name. If God so loved us, then we also ought to love one another. And in that love, the world is given a visible witness that He is truly at work among His people.

Conclusion

In 1 John 4:7–12, the Apostle John does not allow us to speak about love in a shallow or undefined way. He shows us that love is the defining fruit of those who have been born of God. He shows us that the love of God is not measured by earthly comfort or temporary success, but by the sending of His Son into the world so that we might live through Him. And he shows us that those who have received this mercy are not saved into isolation, but brought into the body of Christ where the work of God is meant to be seen.

That means this passage calls for honesty. It calls us to examine the kind of love that is actually present in our lives. Not the kind of love we claim with our mouths, but the kind that can be seen in patience, mercy, truthfulness, humility, and affection for the people of God. John is not giving us a sentimental standard. He is giving us a spiritual one. Where God has given new birth, there will be new fruit. Where He has given a new heart, there will be new affection. And where He truly abides in His people, His love will begin to show itself among them.

This passage also calls us to keep our eyes fixed on the right foundation. The love of God is not grounded in possessions, comfort, influence, or outward success. It is grounded in Jesus Christ, sent into the world to save sinners and to be the propitiation for our sins. If we want to know whether God has loved us, we must begin at the cross. There, His mercy is not guessed at. It is declared. There, His love is not suggested. It is demonstrated.

And finally, this passage reminds us that the church is meant to be the visible display of God’s saving work. The God no one has seen is not absent. His work is visible in the people He has redeemed. When a church loves as those who have received mercy, forgives as those who have been forgiven, and walks together as those who have been reconciled to God through Christ, it becomes a living witness to the gospel it proclaims.

For our church, this is both a comfort and a calling. It is a comfort because it reminds us that God truly does save sinners, give new life, and dwell among His people. It is a calling because we must not be content to speak rightly about His love while failing to display it. If God so loved us, then we also ought to love one another. And in that love, we show the visible evidence that He is truly at work among us.
