Love Is Love? Why God Alone Defines True Love

Editor’s note – This piece walks through 1 John’s argument that God’s own character, not our preferences or culture, defines what love is and does. That distinction shapes how we counsel friends, raise children, and speak into a culture that treats affirmation as the highest form of love.

What “Love Is Love” Leaves Out

“Love is love.”

It sounds almost impossible to challenge. We love our spouses, our children, our friends — enough to sacrifice for them, forgive them, and stand beside them when life falls apart.

But anyone who has truly loved another person knows something else: love does not always say yes. A parent may refuse the car keys when the destination is dangerous; a friend may say something hard to hear. Real love isn’t just giving people whatever they ask for.

So the question isn’t whether love is good — of course it is. The harder question is whether loving someone means affirming whatever they desire, or whether love itself answers to something higher than our desires.

That’s where the slogan “love is love” runs into a wall. Before a slogan can guide our lives, someone has to define what love actually requires — and the dispute isn’t over whether love matters, but over who gets to write its definition.

God Is Love — Not the Reverse

The phrase “God is love” gets invoked constantly today, as if it settles every moral argument. But John doesn’t leave us free to fill in the blank however we like — in 1 John 4:7-11, his argument moves step-by-step:

Its source: Love comes “from God” (v. 7).
Its ground: God’s own character defines it — “God is love” (v. 8).
Its revelation: That love was “manifested toward us” when He sent His Son (v. 9).
Its redemptive content: The Son was sent to be “the propitiation for our sins” (v. 10).
Its ethical consequence: “Beloved, if God so loved us, we also ought to love one another” (v. 11).

Notice what John doesn’t say: not “love is God” — a formula that would make our feelings or cultural trends the ultimate rule — but God is love. His unchangeable character defines what love is; our shifting experiences don’t define who He is.

That is the whole argument in one sentence: God does not answer to our definition of love. Our definition of love must answer to Him.

Editor’s note – Notice the precision here: John never writes ‘love is God,’ which would hand the definition to us. He writes ‘God is love’ – the definition stays fixed even when our feelings shift.

Love, Defined at the Cross

John doesn’t leave love as a vague idea we can bend to fit our preferences. He points us to a historical event: “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” (1 John 4:9), sent “to be the propitiation [or atonement] for our sins” (1 John 4:10).

This is the safeguard the slogan lacks. We often assume real love simply affirms us as we are. But John shows us something deeper: God loved us while we were still sinners, yet His love did not pretend our sin was insignificant or leave us under its guilt.

There’s a word in verse 10 easy to skip past: propitiation — Christ’s sacrificial work by which God’s righteous judgment against our sin is satisfied. Biblical love cannot be reduced to mere approval. The cross demonstrates that God truly loves sinners and that sin is serious enough to require the sacrificial death of His Son.

Love That Isn’t Afraid of Obedience

Once we receive that love, John draws the natural result: “if God so loved us, we also ought to love one another” (1 John 4:11). But required love isn’t left free-floating.

Here popular culture and the Bible part ways. The unspoken rule today says that if an action comes from sincere love, questioning it is itself unloving.

John won’t allow that. A few verses later, he writes:

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. [1 John 5:2-3]

John ties love for others, love for God, and obedience together — you cannot pull them apart. Biblical love doesn’t override the God whose character gives it meaning; obedience isn’t a substitute for love; it is a necessary expression of love toward God.

Paul makes the same point: love “does not rejoice in iniquity, but rejoices in the truth” (1 Corinthians 13:6). Love isn’t measured by how strongly we feel it — genuine love has moral content, and there are things it cannot celebrate because they are contrary to what is true and right before God.

Editor’s note – This section tends to make people uncomfortable because it ties love to obedience rather than sentiment. Paul’s warning that love ‘rejoices in the truth’ rather than iniquity is a check most of us would rather skip.

The Slogan Isn’t Enough

The deepest flaw in “love is love” is something we already understand in everyday life.

If a friend told you, “I love her so much, so whatever I do because of that feeling has to be right,” you’d see the danger immediately. Sincere feeling explains why someone acts; it doesn’t prove the action is wise or good. An experience cannot establish its own moral authority simply by naming itself — affection can slip into obsession, self-destruction, or codependency.

Because of that, everyone — believer or not — brings in other moral standards to judge which expressions of love are healthy and which are harmful.

So when someone says “love is love,” the real question is: which expressions of love are good, and which aren’t?

The moment we ask that, we’ve admitted the slogan isn’t enough — a higher standard has entered the room. Where did it come from? We’re no longer talking about feelings; we’re back to the question every worldview eventually answers: whose authority decides what is good, right, and true?

The Christian argument isn’t that love doesn’t matter. The Christian argument is that love matters too much to leave it undefined.

Turning the Question on Ourselves

This question can’t stop at the culture, though. Scripture confronts the church just as sharply — if God defines love, Christians don’t get a pass to redefine it either.

Believers often make the opposite mistake — insisting love doesn’t mean affirming sin, then acting as though truth gives us permission to be harsh or cruel.

We cannot call contempt love, or mean-spiritedness truth-telling. We have no right to treat someone made in God’s image as an enemy simply because we disagree with their moral conclusions. “I’m just speaking the truth” is never an excuse to abandon kindness.

Paul gives us no permission to pick one over the other: believers are called to be “speaking the truth in love” (Ephesians 4:15). Truth isn’t more faithful for being loud, and love isn’t more caring for ignoring danger. Submitting to God’s authority means letting His definition of love correct us before we use it to correct anyone else.

Editor’s note – Christians can fail the test of love as easily as culture does, just from the other direction – weaponizing truth instead of feeling. Ephesians 4:15 holds truth and love together for a reason; neither one is optional.

What Love Requires

The Christian response to “love is love” is never “love doesn’t matter” — it’s the opposite. Love is too precious to be reduced to a slogan.

John shows us where the definition begins — God is love — and what it looks like in action: God sent His Son as a sacrifice to save us. We can’t reshape love around our own desires, or turn it into a weapon against people we disagree with.

So the ultimate question isn’t whether we believe in love. Almost everyone claims to. The real question is: are we willing to let the God who is love tell us what love actually is?

A Word from the Editor
Every generation redefines love to fit what it already wants. Scripture won’t let us stop at feelings, however sincere – it points us to a Father who loved us enough to send His Son as a propitiation for sin. Real love shows itself there: not in affirming whatever we desire, but in dealing honestly with what separates us from God and providing the way back. “We love because He first loved us” (1 John 4:19) – and that love, not our preferences, is the standard we’re called to imitate.

Editor Comment: As you said, John grounds love in God's unchanging character rather than our shifting feelings, and that distinction protects believers from reshaping love into whatever culture demands.
