Beholding Love
An Exegetical Study of Love in the Writings of John
Love Revealed in the Gospel of John
Love in Practice — 2 John and 3 John
Why This Study Matters
Few words in our language carry more weight and less precision than the word love. We use it to describe our feelings about pizza and our feelings about our children in the very same breath. Scripture will not allow us that kind of carelessness. Nowhere in the Bible is love examined more carefully, defined more sharply, or lived out more vividly than in the writings of the apostle John — his Gospel, and the three short letters that bear his name. John does not merely tell us that God loves us. He shows us what that love looks like, where it comes from, what it costs, and what it produces in those who receive it.
This study walks through the Gospel of John and 1, 2, and 3 John, tracing the theme of love from its source in the Father, through its full revelation in the Son, to its expected shape in the everyday life of the church. My hope is not simply that you would finish this study knowing more about love, but that you would let John’s vision of love unsettle and reshape whatever definition of love you brought with you — that his inspired testimony would become the measure by which we test our own assumptions, rather than the reverse.
A Word About Words
Before we walk through the passages, it helps to understand a little of the vocabulary John had available to him. Koine Greek, the everyday language of the New Testament, had several words we translate as “love.” Eros, referring to romantic or physical desire, never appears in the New Testament at all. Storge, the natural affection of family bonds, appears only in compound form. The two words that matter for our study are agape (and its verb form, agapao) and phileo.
Phileo describes the warmth of friendship — fondness, affection, the love of companions who enjoy one another. It is a good and necessary word, and John uses it without embarrassment, even of the Father’s love for the Son and for believers.
Agape is the word John reaches for again and again to describe the love that defines God’s own character and the love He calls His people to practice. It is not primarily an emotion, though it is not less than that. It is a commitment of the will toward the good of another, a love that acts regardless of what it costs the one doing the loving or what it receives in return. Before the New Testament, agape was a relatively unremarkable Greek word. It is the New Testament writers, and John especially, who fill it with new and startling content: God so loved that He gave. This is the love we will trace through his writings — not a feeling to be stirred up, but a self-giving to be received and then imitated.
Love as Oneness
Ask most people to define love and they will describe a feeling — warmth, attraction, the pull toward someone. That is not a wrong answer. It is only an incomplete one. Read across the whole of Scripture’s teaching about God, about humanity, and about the church, and love keeps appearing in a sturdier shape than a feeling: as the pursuit, the realization, or the expression of oneness — a genuine, shared life between persons who were made for one another and who, apart from that union, remain incomplete.
This pattern shows up in three directions. Divine love is the realization of our oneness with God, expressed throughout the New Testament by phrases like “in Christ” and “in Him.” Paul can say believers are “accepted in the Beloved” (Ephesians 1:6) and have been made “partakers of the divine nature” (2 Peter 1:4) — that is the language of real union, not merely approval from a distance. Love for other believers follows directly: if we are truly one with God, we are one with everyone else who shares in that same union, which is why John can say so bluntly, “If someone says, ‘I love God,’ and hates his brother, he is a liar; for he who does not love his brother whom he has seen, how can he love God whom he has not seen?” (1 John 4:20). And ordinary human love, most visibly in marriage, is the desire for, and the realization of, oneness with another person — Genesis does not describe marriage as a partnership or an arrangement but says two people “shall become one flesh” (Genesis 2:24). Ontology, not merely companionship.
There is even a hint of this in the vocabulary surveyed above. Thayer’s Greek Lexicon calls agape “a purely Biblical and ecclesiastical word” — the New Testament writers took a term that barely existed in everyday Greek and filled it with specifically Christian content: love that seeks another person’s good, not simply love that feels good to the one feeling it. Even at the level of a single word, biblical love is a settled pursuit toward union, not a passing emotion.
Why does this matter practically? Because if love is a feeling, it comes and goes with our mood, our circumstances, our chemistry — and so does our confidence that we are loved. But if love is the pursuit of oneness, it is something that can be built, chosen, and received, even on the days we feel very little. It gives us something to do with a cold marriage, a strained friendship, a faith gone quiet: we do not wait to feel love. We pursue the union it describes. Keep this lens close as we move through John’s Gospel and letters — again and again we will find him describing exactly this: a love that abides, indwells, and makes its home in another.
This framing of love as oneness is explored in far greater depth — including the underlying Greek and Hebrew — in a fuller companion study, Love as Oneness. What follows here draws on that study for this one definitional thread before returning to a close, verse-by-verse reading of John’s own vocabulary of love.
Love Revealed in the Gospel of John
The Origin of Love — John 3:16
“For God so loved the world that He gave His only begotten Son, that whoever believes in Him should not perish but have everlasting life.” (John 3:16)
This may be the most familiar verse in the Bible, and familiarity is precisely what dulls us to how radical it is. John does not say God loved the lovable, or God loved those who first loved Him. He says God loved the world — kosmos, the very created order in its fallen, rebellious state, the same “world” John elsewhere says lies in the power of the evil one and loves darkness rather than light. This is love with no qualifying conditions on its object. And notice the verb: God so loved that He gave. From the very first appearance of agape love in John’s Gospel, love and giving are welded together. Love is not John’s word for how God feels about us. It is John’s word for what God did about us.
This matters enormously for how we think about love today. Our culture often treats love as something that flows naturally toward whatever is attractive, compatible, or deserving — we “fall” into it, as though it happens to us. John 3:16 presents the opposite picture: love that moves toward the unworthy, unattractive, and undeserving, and moves there by decision, at great cost. If we want to know what love is, John says, we do not start by consulting our feelings. We start by looking at the cross.
The Love That Serves — John 13:1–17, 34–35
“Now before the feast of the Passover, when Jesus knew that His hour had come that He should depart from this world to the Father, having loved His own who were in the world, He loved them to the end.” (John 13:1)
John places this verse as the hinge of his entire Gospel. Everything before chapter 13 has shown Jesus revealing Himself to the world; everything after shows Him loving His own to the end — literally, to completion, to the uttermost. And how does John show us that love in the very next verses? Not with a speech about love, but with a towel and a basin. Jesus kneels and washes the feet of His disciples, taking the position of the lowest household servant. Love, in John’s Gospel, is not first spoken. It is first knelt.
Out of that same evening comes the command that will echo through the rest of the New Testament: “A new commandment I give to you, that you love one another; as I have loved you, that you also love one another. By this all will know that you are My disciples, if you have love for one another” (John 13:34–35). Notice the standard: not love as you are naturally inclined to love, not love as your culture defines love, but as I have loved you — a love measured by a towel and, soon, by a cross. Notice also the stakes: this love is the evidence. Doctrine matters immensely to John, as we will see, but he tells us plainly that the watching world will know whether Jesus’s disciples are real by nothing more and nothing less than whether they love one another as He loved them.
Obedience as the Grammar of Love — John 14:15, 21, 23
“If you love Me, keep My commandments.” (John 14:15)
“He who has My commandments and keeps them, it is he who loves Me. And he who loves Me will be loved by My Father, and I will love him and manifest Myself to him.” (John 14:21)
“If anyone loves Me, he will keep My word; and My Father will love him, and We will come to him and make Our home with him.” (John 14:23)
Three times in one chapter, Jesus binds love and obedience together so tightly that they become almost indistinguishable. This is one of the places where John most directly confronts a modern assumption about love — namely, that love and obligation are opposites, that “real” love is spontaneous and unconstrained, and that rules are what love has to overcome. John 14 says nearly the reverse: obedience is not the barrier to loving Jesus; it is the very grammar in which love is spoken. A love for Jesus that never expresses itself in a changed life, in actual obedience to what He has said, is not yet the love John is describing, however sincerely it may be felt. And notice the promise attached: to the one who loves and obeys this way, Jesus promises nothing less than the indwelling presence of the Father and the Son. Obedient love is not a transaction that earns God’s affection; it is the open door through which His presence comes to make its home in us.
Abiding Love and the Greatest Love — John 15:9–13
“As the Father loved Me, I also have loved you; abide in My love. If you keep My commandments, you will abide in My love, just as I have kept My Father’s commandments and abide in His love… This is My commandment, that you love one another as I have loved you. Greater love has no one than this, than to lay down one’s life for his friends.” (John 15:9–10, 12–13)
Here John shows us love flowing in an unbroken chain: from the Father, to the Son, and from the Son, to us — and then, He says, we are to abide in it, the way a branch abides in a vine. Love, in this picture, is not a burst of energy we generate and then hope survives the week; it is a place we dwell, sustained from outside ourselves, moment by moment. And Jesus defines the outer limit of that love in a single sentence that history has never been able to improve upon: greater love has no one than this, than to lay down one’s life for his friends. Within days, Jesus would do exactly that. Every other claim to love, measured against this one, is revealed for how small it actually is.
Love Restored — John 21:15–17
“So when they had eaten breakfast, Jesus said to Simon Peter, ‘Simon, son of Jonah, do you love Me more than these?’ He said to Him, ‘Yes, Lord; You know that I love You.’ He said to him, ‘Feed My lambs.’ He said to him again a second time, ‘Simon, son of Jonah, do you love Me?’ He said to Him, ‘Yes, Lord; You know that I love You.’ He said to him, ‘Tend My sheep.’ He said to him the third time, ‘Simon, son of Jonah, do you love Me?’ Peter was grieved because He said to him the third time, ‘Do you love Me?’ And he said to Him, ‘Lord, You know all things; You know that I love You.’ Jesus said to him, ‘Feed My sheep.’” (John 21:15–17)
In the original Greek, the first two times Jesus asks Peter this question He uses agapao — do you love Me with that self-giving, committed love? — and both times Peter answers with phileo, the love of a friend: You know that I am fond of You. On the third question, Jesus Himself shifts to phileo, meeting Peter where he is, and it is this — the third repetition, echoing Peter’s threefold denial in the courtyard — that grieves him. Many careful readers of John’s Gospel are honestly divided over how much theological weight the change in verbs will bear, since John elsewhere seems to vary his vocabulary for simple literary color — using two different words for “know,” two different words for “sheep,” two different words for “feed” and “tend” in this very passage without any evident change in meaning. So we should hold the fine distinction of agapao and phileo here with an open hand rather than build a whole doctrine upon it.
But we need not settle that scholarly question to see the pastoral heart of the scene, which no reader misses. A disciple who denied his Lord three times by a charcoal fire (John 18:18) is met again beside a charcoal fire (John 21:9) and is restored, three declarations of love answered by three commissions to serve: feed My lambs, tend My sheep, feed My sheep. Whatever we make of the Greek verbs, the passage itself teaches something essential about Johannine love: it is a love that pursues the failed and the ashamed, that does not demand a perfect love before it will use us, and that always turns love for Jesus into love expressed as care for His people.
Love Defined in 1 John
If the Gospel of John shows us love enacted in the life of Jesus, the First Letter of John gives us the theology behind it — the fullest, most concentrated treatment of love anywhere in Scripture, written by an old man near the end of his life to a church he clearly adored.
Called Children of Love — 1 John 3:1
“Behold what manner of love the Father has bestowed on us, that we should be called children of God!” (1 John 3:1)
John begins not with a command but with an exclamation. Before he tells his readers anything they must do about love, he stops to marvel at what has already been done for them. This order matters. Every command to love that follows in this letter is a command given to people who have already been loved first, adopted, and named children of God. Christian love, in John’s theology, is always response before it is duty.
Love in Deed and Truth — 1 John 3:11–18
“By this we know love, because He laid down His life for us. And we also ought to lay down our lives for the brethren. But whoever has this world’s goods, and sees his brother in need, and shuts up his heart from him, how does the love of God abide in him? My little children, let us not love in word or in tongue, but in deed and in truth.” (1 John 3:16–18)
John will not let love remain a sentiment or a slogan. He defines it by an event — the laying down of Christ’s life — and then insists that our love be tested the same way: not by what we say, but by what we do when a brother or sister is in actual need in front of us. It is a sobering diagnostic. John does not ask whether we feel love toward the people in our church, our family, our neighborhood. He asks whether that love has ever cost us anything tangible — our goods, our time, our comfort — and if not, he questions whether the love of God abides in us at all.
God Is Love — 1 John 4:7–21
This passage is the theological heart not only of the letter but of the entire Johannine understanding of love, and it deserves to be read slowly.
“Beloved, let us love one another, for love is of God; and everyone who loves is born of God and knows God. He who does not love does not know God, for God is love.” (1 John 4:7–8)
Here John makes a claim about God’s own essence that no other writer in Scripture states so plainly: God is love. Not merely that God loves, or that God is loving among His other attributes, but that love belongs to who God is at the very core of His being. And because that is true, John says, love becomes the test of whether a person actually knows God at all. This is not a suggestion that anyone who has warm feelings automatically knows God — John will define love with great precision in the verses that follow — but it is a serious claim: theology divorced from love is not real knowledge of the God who is love.
“In this the love of God was manifested toward us, that God has sent His only begotten Son into the world, that we might live through Him. In this is love, not that we loved God, but that He loved us and sent His Son to be the propitiation for our sins.” (1 John 4:9–10)
John defines love, once again, by an act — the sending of the Son, specifically as a propitiation, the sacrifice that satisfies God’s righteous judgment against sin and turns aside His wrath. This is important because it means the love of God, in John’s hands, is never sentimental or soft. It is a love that deals honestly and costly with sin rather than pretending sin does not matter. And John is careful to locate the initiative entirely with God: not that we loved Him, but that He loved us. Every human love described anywhere in this letter is downstream from this one.
“There is no fear in love; but perfect love casts out fear, because fear involves torment. But he who fears has not been made perfect in love… We love Him because He first loved us.” (1 John 4:18–19)
And here John shows us love’s effect on the human heart: it drives out fear — not the fear of danger, but the fear of judgment, the anxious uncertainty of whether we are truly accepted. A heart that has grasped how thoroughly it is loved by God no longer needs to perform, prove itself, or hide. This is the psychological and spiritual freedom that flows from believing 1 John 4:9–10 rather than merely reciting it.
“If someone says, ‘I love God,’ and hates his brother, he is a liar; for he who does not love his brother whom he has seen, how can he love God whom he has not seen? And this commandment we have from Him: that he who loves God must love his brother also.” (1 John 4:20–21)
John closes the chapter the way he opened it — refusing to let love toward God be separated from love toward people. Love of God that never becomes love of the people God has placed around us is not, in John’s estimation, love of God at all. It is a lie we tell ourselves.
Love That Obeys — 1 John 2:5 and 5:2–3
“But whoever keeps His word, truly the love of God is perfected in him.” (1 John 2:5)
“By this we know that we love the children of God, when we love God and keep His commandments. For this is the love of God, that we keep His commandments. And His commandments are not burdensome.” (1 John 5:2–3)
Just as in the Gospel, John will not permit love and obedience to be pried apart in his letter. But notice the final phrase of 1 John 5:3 — His commandments are not burdensome. This is not the grudging obedience of someone earning favor they are not sure they have. It is the glad obedience of someone who has already been assured, in chapter after chapter, that they are loved children of God. Obedience, for John, is not the price of love. It is love’s natural shape once it has taken root.
Love Without Rivals — 1 John 2:15
“Do not love the world or the things in the world. If anyone loves the world, the love of the Father is not in him.” (1 John 2:15)
John uses the same word, agapao, for a love that must be refused as for the love that must be embraced. This tells us something important: the human heart is always loving something. The question is never whether we will love, but what. A heart set on loving “the world” — here meaning the whole system of values organized around pride, appetite, and self-sufficiency apart from God — cannot, at the same time, be filled with love for the Father. Love, for John, is not infinitely elastic. It has a shape, and that shape excludes rival loves that would compete with it for the throne of the heart.
Love in Practice — 2 John and 3 John
John’s two shortest letters are easy to overlook, but each adds a necessary brushstroke to the picture.
Truth and Love Together — 2 John 1, 5–6
“The Elder, To the elect lady and her children, whom I love in truth… I plead with you, lady, not as though I wrote a new commandment to you, but that which we have had from the beginning: that we love one another. This is love, that we walk according to His commandments. This is the commandment, that as you have heard from the beginning, you should walk in it.” (2 John 1, 5–6)
John opens this brief letter loving in truth — a small phrase that guards against two opposite errors. Love without truth collapses into sentimentality that will affirm anything in the name of kindness; John spends the rest of this short letter warning against deceivers who deny that Jesus Christ has come in the flesh, and he does not soften that warning in the name of love. But truth without love hardens into a kind of doctrinal policing with no warmth in it at all — and that is not John’s spirit either. He holds both together: real love always walks according to what is actually true.
Love Made Visible — 3 John 1
“The Elder, To the beloved Gaius, whom I love in truth.” (3 John 1)
John’s shortest letter is essentially a thank-you note, written to commend Gaius for his hospitality toward traveling missionaries and to grieve over Diotrephes, a man in the same church “who loves to have the preeminence” and refuses to welcome the brethren at all (3 John 9–10). Placed side by side, these two men give us love’s simplest test in ordinary church life: does this person’s life make room for others, or only for themselves? John’s final word on love, fittingly, is not another definition but a small, concrete story — because that is where love, in the end, has to be proven.
The Shape of Johannine Love
Stepping back from the individual passages, a single, coherent picture of love emerges across everything John wrote. Love originates in the Father, who is love by nature and not merely by choice. That love was fully revealed in the sending and self-giving of the Son, most visibly at the cross, where love and cost are shown to be inseparable. This love, once received, cannot remain private; it is always meant to reproduce itself in the believer as love for God expressed in obedience and love for others expressed in tangible, costly action. And this love is, finally, the evidence — the one mark John returns to again and again — by which the world will recognize genuine disciples and by which believers may test whether they truly know the God who is love.
A Call to a Renewed Mind
It would be possible to finish a study like this one with a great deal of new information about love and no change at all in how we actually love. John would not be satisfied with that outcome, and neither should we be.
Consider, honestly, where your own working definition of love came from. For most of us, it was shaped far more by songs, films, and the ordinary assumptions of the culture around us than by careful attention to Scripture. That definition usually prizes feeling over will, ease over cost, and compatibility over commitment. It treats love as something that happens to us and, just as easily, as something that can stop happening to us — a love with an exit built in whenever the feeling fades.
John will not let that definition stand unchallenged. He has shown us a love that begins in a Father who gives before He is asked, a Son who kneels with a towel and dies on a cross for people who do not deserve it, and a community called to walk in that same pattern — not in word or in tongue, but in deed and in truth. To take John seriously is to let this vision correct ours at every point where they disagree: to stop asking whether love feels a certain way and start asking whether it looks like Jesus; to stop treating obedience as love’s enemy and start receiving it as love’s evidence; to stop measuring love by what it costs to receive and start measuring it by what it costs to give.
Ask yourself, in the quiet of your own reflection, where this study has exposed the gap between John’s definition of love and your own. Is there a relationship in which your love has never yet cost you anything? Is there an area of obedience you have quietly treated as optional, as though love for Jesus and submission to His word were two separate things? Is there a fear still gripping you that the perfect love of 1 John 4 was meant to cast out? John did not write these words so that we would admire them from a distance. He wrote so that, having beheld what manner of love the Father has given us, we would be slowly, steadily remade into people who love the same way.
