The word “love” appears more than five hundred times across the pages of Scripture, and it sits at the centre of everything the Bible says about God, about human beings, and about how the two are meant to relate to each other. Jesus summarises the entire law in terms of love. John declares that God is love, not merely that He is loving. Paul places love above faith and hope as the greatest of the three enduring virtues. Whatever else Christianity is, it is inescapably a religion about love.
Yet love is also one of the most misunderstood words in our culture. In English, a single word carries the weight of an enormous range of experiences: the tenderness of a parent for a child, the passion of romantic devotion, the loyalty of deep friendship, the compassion that moves toward a stranger in need. In Greek, the language of the New Testament, different words exist for different kinds of love, and understanding these distinctions opens up the biblical teaching considerably.
But before we examine what love is, Scripture insists on something foundational: we do not generate love from within ourselves and then offer it to God or others. We receive it first. First John 4:19 states this plainly: “We love, because He first loved us.” Any serious engagement with biblical love has to begin there.
The Words for Love: What the Greek Reveals
The New Testament uses two primary Greek words for love: agape and phileo. A third word, eros, which refers to romantic or erotic love, does not actually appear in the New Testament at all, which is worth knowing before we discuss it. There is also a fourth word, storge, which describes natural familial affection. Together, these words show that love is not a single, undifferentiated thing but a whole family of related experiences and commitments.
Agape is the word the New Testament uses most frequently for the love of God and the love He commands His people to practise. It is not, in the first instance, an emotion. It is a chosen, willed disposition toward another person that seeks their genuine good regardless of what they deserve or how one feels in the moment. When Paul writes his famous description of love in 1 Corinthians 13, every word he uses describes a posture of the will, not a flutter of feeling:
Love is patient, love is kind and is not jealous; love does not brag and is
not arrogant, does not act unbecomingly; it does not seek its own, is not
provoked, does not take into account a wrong suffered, does not rejoice in
unrighteousness, but rejoices with the truth; bears all things, believes all
things, hopes all things, endures all things. (1 Corinthians 13:4-7, NASB)
Notice what is and is not in this list. There is nothing here about feeling warm toward someone, nothing about attraction, nothing about the pleasant sensation of being with someone you enjoy. Instead, Paul describes a series of choices: to be patient when patience is difficult, to refuse to rejoice in someone’s failure, to go on bearing and believing and hoping when circumstances argue against it. This is why agape-love is something that can be commanded. You cannot command a feeling. You can command a choice.
The Greek word phileo describes something closer to what we might call deep affection or friendship love. It is the warmth of genuine companionship, the pleasure of being with someone whose company you value. When John records that Jesus wept at Lazarus’s tomb and the bystanders said, “See how He loved him!” (John 11:35-36), the word used is a form of phileo. It is the same word-family from which Philadelphia gets its name, “the city of brotherly love.” Phileo is not a lesser love than agape; it is a different dimension of love, one that involves genuine emotional warmth and delight in another person.
Storge, though less prominent in the NT texts, describes the instinctive affection between family members. Paul uses it in Romans 12:10 when he urges believers to be “devoted to one another in brotherly love”; the word translated “brotherly love” there combines phileo and storge into a single compound. The household metaphor of the church family, with God as Father and believers as brothers and sisters to each other, draws heavily on this kind of love.
Eros, the word for romantic and passionate love, does not appear in the New Testament. This does not mean the Bible ignores romantic love; it means such love is expressed through other language and imagery. The Song of Solomon is the Bible’s most extended meditation on it, written in poetry of striking intimacy. Its famous declaration:
Put me like a seal over your heart,
Like a seal on your arm.
For love is as strong as death,
Jealousy is as severe as Sheol;
Its flashes are flashes of fire,
The very flame of the LORD. (Song of Solomon 8:6, NASB)
This is Scripture treating romantic love with complete seriousness. The comparison to death, the one force that no human can resist or overcome, is not an exaggeration but a theological statement about the God-given intensity of this kind of love. The phrase “the very flame of the LORD” in the Hebrew is literally “the flame of Yah,” connecting human romantic love to the divine fire itself. Eros-love, properly understood and expressed within the covenant of marriage, is not a secular concession but carries its own sacred weight.
The Source: God Is Love
None of the different forms of love we have been describing can be properly understood apart from their source. The New Testament makes a claim about God that is without parallel in any other religion: not that God is loving, or that He loves, but that He simply is love. First John 4:8:
The one who does not love does not know God, for God is love. (1 John 4:8, NASB)
The Greek here is theos agape estin: God love is. This is not a description of one of God’s attributes alongside others. It is a statement about His nature. Love is not something God does from time to time; it is what He is. This means that when we encounter genuine love anywhere, we encounter something that originates in God. It means that God’s love for us is not contingent on our lovableness; it flows from what He is rather than from what we deserve.
John goes immediately from this declaration to its concrete demonstration:
By this the love of God was manifested in us, that God has sent His only
begotten Son into the world so 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, NASB)
This is the sequence that matters. God’s love is not abstract; it became historical. The declaration “God is love” is not a mystical statement but one that can be pointed to on a map, pinned to a date. The love of God was “manifested,” made visible and concrete, in the sending of His Son. And the direction is crucial: “not that we loved God, but that He loved us.” Love, in Scripture, never begins with the human being and moves toward God. It begins in God and moves toward us.
This reversal of direction explains the verse we started with: “We love, because He first loved us” (1 John 4:19). Our capacity to love anyone, whether God, neighbour, or enemy, is not a moral achievement we summon from within ourselves. It is a response, and a response is only possible because something arrived first. The love we are called to practise is not manufactured from scratch; it is received and then passed on.
Love Poured Into Us: Romans 5:5
This matters enormously for how we understand the demand to love. Paul does not treat love simply as a moral obligation to be grimly discharged. He grounds it in a gift:
hope does not disappoint, because the love of God has been poured out within
our hearts through the Holy Spirit who was given to us. (Romans 5:5, NASB)
The image is of something being poured out generously, abundantly, into the interior of a person. This is not a trickle; the Greek verb is ekcheo, which can mean to pour out, to shed, to lavish. The love of God has been lavished into our hearts by the Holy Spirit. Before love is something we do, it is something that has been done in us.
This shapes the entire posture of biblical ethics around love. The Christian is not someone straining to love from an empty interior, generating agape through moral willpower. The Christian is someone in whom God’s love has been poured, and who is called to live from that reality. This does not make love effortless; Paul would not have needed to urge, command, and describe it if it were. But it changes the dynamic from mere duty to grateful overflow.
The New Commandment: Love as Jesus Loved
On the night before His crucifixion, Jesus gave His disciples something He described as new:
A new commandment I give to you, that you love one another, even as I have
loved you, that you also love one another. By this all men will know that
you are My disciples, if you have love for one another. (John 13:34-35, NASB)
The commandment to love was not new in itself; the Torah had commanded love of neighbour since Leviticus 19:18. What was new was the standard: “even as I have loved you.” Jesus sets His own love as the measure. This is a startlingly high bar. His love involved washing feet, welcoming the outcast, touching the leper, eating with the despised, and ultimately laying down His life. He is not asking His disciples to feel warmly about each other. He is asking them to structure their lives in service of each other after the pattern of His own.
Notice also what Jesus says will be the result: visibility. The way the community of disciples treats one another will be legible to the watching world as a marker of genuine discipleship. Love here is not primarily an interior state but a visible social reality, the kind of community that makes onlookers say, “See how they love one another.”
And love is directly tied to obedience in a way we cannot soften or ignore. Just a chapter later, Jesus says:
“If you love Me, you will keep My commandments. (John 14:15, NASB)
This is stated as a natural consequence, not a test. The future tense (“you will keep”) is not threatening but descriptive: the person who genuinely loves Jesus will naturally, as an expression of that love, keep His words. Love and obedience are not two separate things in tension with each other; obedience flows out of love as its natural fruit. This connection between loving Jesus and doing what He says runs through the whole of John’s Gospel (14:21, 23; 15:10) and prevents love from becoming a merely sentimental category.
The Hardest Part: Loving Enemies
Any serious treatment of love in the Bible has to engage the part of Jesus’s teaching that is most distinctive, most demanding, and most difficult to domesticate:
“You have heard that it was said, ‘YOU SHALL LOVE YOUR NEIGHBOR and hate
your enemy.’ But I say to you, love your enemies and pray for those who
persecute you, so that you may be sons of your Father who is in heaven; for
He causes His sun to rise on the evil and the good, and sends rain on the
righteous and the unrighteous. For if you love those who love you, what
reward do you have? Do not even the tax collectors do the same? (Matthew 5:43-46, NASB)
Jesus is not describing an emotion. He is not telling His disciples to feel affection for those who persecute them. He is describing a willed orientation that continues to seek the other person’s genuine good even when that person is hostile. The evidence of this kind of love is prayer: praying for the one who is causing harm is the concrete act that makes enemy-love something more than a pious sentiment.
The reason Jesus gives is theological: this is what God is like. God causes His sun to rise on the evil and the good alike. He does not restrict His kindness to those who deserve it, because kindness, at its source in God, does not operate on the principle of desert. The disciples are called to become “sons of your Father” by imaging the way God loves: indiscriminately, toward the hostile as well as the friendly.
The challenge of enemy-love is the point at which most comfortable versions of Christianity quietly stop. It is easier to love people who love us in return; even, as Jesus notes, the tax collectors do that. The distinguishing mark of the Christian community is supposed to be the extension of love beyond the boundaries of reciprocity, beyond the circle of those who deserve it or will return it. This is not natural. It requires exactly the kind of supernatural resource that Romans 5:5 describes: the love of God poured into human hearts by the Spirit.
Love and the Greatest Commandment
When a lawyer asked Jesus which commandment was the greatest in the Law, He gave the answer that remains the organising principle of Christian ethics:
And He said to him, ‘”YOU SHALL LOVE THE LORD YOUR GOD WITH ALL YOUR
HEART, AND WITH ALL YOUR SOUL, AND WITH ALL YOUR MIND.” This is the great
and foremost commandment. The second is like it, “YOU SHALL LOVE YOUR
NEIGHBOR AS YOURSELF.” On these two commandments depend the whole Law
and the Prophets.’ (Matthew 22:37-40, NASB)
Jesus does not simply select the greatest commandment from a ranked list. He shows that the entire Law, “the whole Law and the Prophets”, hangs on these two. Every other commandment is an expression or application of love toward God and love toward neighbour. Keep these, and you will keep all the rest. Fail in these, and keeping all the rest becomes legalism without soul.
The order is significant. Love of God comes first, and not incidentally: it is described as total. All the heart, all the soul, all the mind. There is no compartment of a person that is reserved from this love. This is why the connection between love and obedience matters: if God is to be loved with everything, then love will inevitably touch every area of life, including the areas we might prefer to keep private from Him.
The second commandment, “love your neighbour as yourself”, is grounded in the first. The practical question of how to treat another human being cannot be separated from the theological question of who God is and how He has already treated you. Love of neighbour that loses its grounding in love of God becomes a human project that eventually runs out of resources. Love of God that does not express itself in love of neighbour becomes a privately enjoyed religion that James, for one, is not prepared to take seriously.
Love That Acts: What James Demands
James raises the hardest practical question about love: what does it actually do? He is not prepared to accept a love that operates only in the realm of feeling or intention:
If a brother or sister is without clothing and in need of daily food, and
one of you says to them, “Go in peace, be warmed and be filled,” and yet
you do not give them what is necessary for their body, what use is that?
Even so faith, if it has no works, is dead, being by itself. (James 2:15-17, NASB)
The image is deliberately uncomfortable. Someone is cold and hungry. A Christian says the right words, warm words, pious words, words that wish them well, and then does nothing concrete to address the cold and the hunger. James says this is not love. It is the form of love without the substance.
The connection James makes is between faith and works, but it applies equally to love. A love that does not move the hands and the wallet, that remains a feeling or a sentiment but never becomes action, is not yet the love the New Testament is describing. John makes the same point in his first letter: “Little children, let us not love with word or with tongue, but in deed and truth” (1 John 3:18, NASB). The love that God is and that He pours into human hearts is, by its very nature, active and outward-moving. It does not stay inside.
Love and Peter: The Question That Will Not Let Us Go
One of the most searching passages about love in the entire Bible is the conversation between the risen Jesus and Peter on the beach in John 21. Peter has denied Jesus three times. Jesus has been crucified and risen. Now, at a charcoal fire on the shore of Galilee, Jesus asks Peter the same question three times:
So when they had finished breakfast, Jesus said to Simon Peter, “Simon, son
of John, do you love Me more than these?” He said to Him, “Yes, Lord; You
know that I love You.” He said to him, “Tend My lambs.” He said to him
again a second time, “Simon, son of John, do you love Me?” He said to Him,
“Yes, Lord; You know that I love You.” He said to him, “Shepherd My sheep.”
He said to him the third time, “Simon, son of John, 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, “Tend My sheep.” (John 21:15-17, NASB)
The repetition is deliberate. Three denials; three questions. Jesus is not tormenting Peter but healing him, giving him the chance to affirm love three times in the place where he had denied three times. The text in Greek preserves a distinction that English translations tend to flatten: in the first two questions Jesus uses agapas (the agape form), and Peter responds with phileis (the phileo form). When Jesus asks the third time, He shifts to phileis, meeting Peter where Peter is.
What this exchange shows is that Jesus takes both the question of love and the honest condition of the one answering it seriously. Peter cannot yet claim the full, unconditional agape-love. He has just betrayed Jesus. What he can honestly say is “You know that I am fond of You, that I am Your friend.” Jesus accepts this and commissions him anyway: “Tend My sheep.” Love, even incomplete love, honestly confessed, is the basis for service. The call is not deferred until Peter’s love reaches some higher standard. It is given now, in this moment, with what is true.
The question does not stay in the first century. Every generation of disciples is asked it: “Do you love Me?” And the honest answer will determine everything else.
The Foundation That Holds
Biblical love, in its fullness, is both simpler and harder than most of our culture’s versions of it. Simpler, because its foundation is not our own capacity to feel or achieve but the love of God already poured into us by His Spirit. Harder, because it extends to enemies, demands action, outlasts feeling, and asks to be expressed toward those who have no claim on us.
The logic of the whole thing hangs together. God is love. He sent His Son as the concrete historical expression of that love. His love has been lavished into our hearts through the Spirit. Out of that received love, we are called to love God with everything we are and neighbours with everything we have, including neighbours who are hostile, cold, and undeserving. This is not a programme for spiritual self-improvement. It is a description of what happens when the love that is God’s own nature begins to take root in a human life.
John 3:16 remains the simplest summary of the whole arc:
“For God so loved the world, that He gave His only begotten Son, that
whoever believes in Him shall not perish, but have eternal life. (John 3:16, NASB)
God loved. He gave. Whoever receives this will not perish. The movement is all outward, all generous, all initiating. And we, loved, given to, given life, are invited to become in the world what God has already been toward us.
This article has mapped the biblical framework and vocabulary of love. The companion article “Learning to Love Yourself and Others as God Loves You” addresses the personal and pastoral experience of actually doing it: the struggle with self-contempt and what Scripture says about proper self-regard, the practical shape of biblical self-love, how to love difficult people and enemies in concrete terms, and forgiveness as a specific act distinct from reconciliation. Where this article builds the theological foundation, that one works out what it looks like to live from it.
