It is the verse on the placard behind the goalposts. Most people who could not name a single other line of Scripture can produce this one. This is the kosmos meaning in the Bible.
For God so loved the world, that he gave his only Son, that whoever believes in him should not perish but have eternal life.
I want to look at one word in it, because English flattens something that the Greek keeps open, and the flattening quietly changes what the verse is doing.
The word
The Greek is kosmos. It appears something like a hundred and eighty times in the New Testament, and John uses it more than anyone.
Its root sense is an ordered arrangement — a system, a whole with a structure to it. Thayer’s begins with orderly arrangement and even adornment, which is why an English word for jewelry comes from the same root.
From there it spreads out. Lexicons give the range: the universe as an ordered whole; the earth; the inhabitants of the earth; the human race; and then a further sense that is unmistakably negative — the mass of humanity alienated from God, and the whole system of earthly values and appetites organized in opposition to him.
So the same word can mean creation, and humanity, and the thing you are told not to love.

Which is exactly the problem
Because John uses it in all those senses, sometimes within a few lines of each other.
In the same gospel: the world was made through him, and the world did not know him. First sense, then second.
And in the same author’s first letter: do not love the world or the things in the world.
Put those next to John 3:16 and you have a genuine difficulty. God loves the world. Do not love the world. Both from John.
The resolution is not clever. It is just that the word is doing different jobs. When John says God loved the kosmos, he means the people — the whole race of them, without limit of nation or qualification. When he says do not love the kosmos, he means the system: the arrangement of appetites and status and self-rule that people build and are ruled by.
Same word. Different referent. Any decent lexicon will tell you this, and every tradition’s commentators have said it for centuries.
The very next verse uses it three more times in a single sentence: God did not send his Son into the world to condemn the world, but in order that the world might be saved through him. Sent into it, not sent to condemn it, sent so that it might be saved. Whatever else John is doing with this word, he is not being careless with it. He leans on it.
Why it matters that it means people
Here is where the flattening costs us something.
Read “world” as an abstraction — the planet, the general run of things — and John 3:16 becomes a statement about God’s benevolent disposition toward creation in general. Warm, and slightly weightless.
Read it as the lexicons do, as the human race in its actual condition, and it lands very differently. The word John reaches for is not a neutral one in his vocabulary. Two chapters later he will describe this same world as not knowing him, not receiving him. In his letter he will describe it as lying in the power of the evil one.
That is the object of the loving.
Not humanity considered abstractly at its best. Humanity as John elsewhere describes it — the ones who did not recognize him when he came.
The scope
The other thing the word carries is size, and this is where the verse has done its real work for two thousand years.
He does not say God so loved Israel, which is what the first hearers might have expected in a conversation with a Pharisee at night. He does not say God so loved the righteous, or those who were going to believe, or the ones who deserved it.
Kosmos is the widest word available. It is the whole ordered mass of them.
Christians have argued for a very long time about how the extent of that love relates to the extent of its effect, and I am not going to settle that here — it runs directly into questions about election that the traditions genuinely divide on, and pretending otherwise would be dishonest.
What every tradition holds is what the verse plainly says: the object of God’s love is not a subset small enough to be comfortable.
What the sentence is attached to
The verse is almost never read with the two verses standing in front of it, and those are the ones that set it up.
And as Moses lifted up the serpent in the wilderness, so must the Son of Man be lifted up, that whoever believes in him may have eternal life.
That is Numbers 21. Israel complains on the road, snakes come into the camp, people are bitten and die. Moses is told to make a bronze serpent and set it on a pole, and anyone who has been bitten looks at it and lives.
It is a strange thing to reach for. There is nothing dignified about it. The remedy is a model of the thing that is killing you, mounted where everyone can see it, and your entire part in the transaction is to look.
John 3:16 comes one breath after that. So God loved the world. The sentence is not floating free on a placard. It is fastened to an image of something raised up in public where people can see it, and to a verb — lifted up — that John uses again later, and then stops to explain: he said this to show by what kind of death he was going to die.

And the second half of the sentence
While we are here, the verse has a structure that the placard version obscures.
God so loved the world, that he gave.
The “so” is not primarily about intensity, the way we usually hear it — God loved the world so much. In the Greek it is closer to manner: this is how God loved the world, namely, by giving.
The popular reading is not baseless, and it would be cheap to pretend otherwise. The word can carry degree, and some scholars argue that here it carries both at once, the manner of the love and its extent together. What was given does show a love of enormous size. But the sentence points first at the how.
Which is a harder and better sentence. The love is not a feeling reported about God. It is defined by an action taken and a cost paid. You do not have to guess at the sincerity of it, or work up warm feelings toward the idea of it. You are pointed at something that happened.
That is a genuine mercy on weeks when you feel nothing. The verse is not asking you to detect divine affection in your interior weather. It is telling you what was done.
One honest footnote
You will see this in the margin of your own Bible, so it is worth saying out loud.
Ancient Greek was written without quotation marks. Nothing in the text tells you where Jesus stops speaking to Nicodemus and John starts commenting on him, and the translations disagree. Some close the quotation at verse fifteen, which makes verse sixteen the evangelist’s own words. Others run it to verse twenty-one. Careful scholars sit on both sides of that.
It changes who is speaking. It does not change a syllable of what is said, and nothing in the verse depends on the answer. But the red letters in your Bible are an editor’s judgment rather than a feature of the manuscript, and it is better to know that than to be startled by it later.
What to do with it
Try reading it slowly, with the word unpacked, as though you had never seen it:
This is how God loved the ordered mass of human beings who did not recognize him: he gave his only Son, so that anyone at all who trusts him would not be destroyed but have the life of the age to come.
That is closer to what is on the page than the version on the placard.
And it is worth noticing where the sentence sits. Not in a sermon, not in front of a crowd. It comes in the middle of a private, slightly awkward night conversation with a religious professional who had come with questions and did not want to be seen coming.
Which is its own encouragement, if you have ever had questions you did not want to raise in daylight.
John does not drop him, either. Nicodemus turns up twice more. In chapter seven, with the authorities trying to have Jesus arrested, he asks a careful procedural question — does our law judge a man without first giving him a hearing? — and gets a sneer for it. Then at the very end, after the crucifixion, when almost everyone else has scattered, he arrives with Joseph of Arimathea carrying about seventy-five pounds of myrrh and aloes for the burial.
And John cannot introduce him even there without the old detail attached. Nicodemus, who earlier had come to Jesus by night.
The night visit stayed on his name. It did not stop him coming back.
