Quick Answer
The Greek word for goodness in the fruit of the Spirit is agathosyne (ἀγαθωσύνη), pronounced ah-gah-thoh-SOO-nay, Strong’s G19. It means goodness as an active, upright quality: a goodness that does good, and that is strong enough to correct and confront when love requires it. It appears only four times in the New Testament, all in Paul’s letters, and it is the word behind “goodness” in Galatians 5:22.
Word Study: Where It Comes From
Agathosyne is built on agathos (ἀγαθός, G18), the ordinary Greek adjective for “good,” plus the suffix -syne, which turns a quality into an abstract noun (the same way dikaios, “righteous,” becomes dikaiosyne, “righteousness”). So the word is literally “good-ness”: the quality of being agathos.
Here is the part most readers never hear. Agathos is everywhere in classical Greek, but agathosyne is not. You will not find it in Plato or Aristotle. It first shows up in the Greek translation of the Old Testament, the Septuagint, made by Jewish scholars a couple of centuries before Jesus. When they translated Nehemiah 9:25, where Israel “delighted themselves in thy great goodness,” they reached for this word. Greek had plenty of ways to call something good. What it lacked was a single noun for goodness as a living force that comes out of a person and acts on the world. The Bible’s translators supplied one, and Paul picked it up.
That origin matters. Agathosyne is not a borrowed philosophical term for being a decent person. It is a word born inside Scripture to describe the kind of goodness God has and gives. When Paul lists it as fruit of the Spirit, he is saying that this same goodness can grow in a human life.
And it is a goodness with a spine. Agathos in the New Testament often carries the sense of being good for something, useful and beneficial in a moral way. Its noun leans active, not passive. Agathosyne is not the absence of wrongdoing. It is goodness that gets up and does something, even when the thing that needs doing is hard.

Where This Word Appears in the Bible
Agathosyne appears exactly four times in the New Testament. Here is every one of them:
| Reference | KJV Text | What Agathosyne Adds |
|---|---|---|
| Romans 15:14 | “And I myself also am persuaded of you, my brethren, that ye also are full of goodness, filled with all knowledge, able also to admonish one another.” | Goodness as the thing that qualifies you to correct someone |
| Galatians 5:22 | “But the fruit of the Spirit is love, joy, peace, longsuffering, gentleness, goodness, faith,” | Goodness as something the Spirit grows, not something you manufacture |
| Ephesians 5:9 | “(For the fruit of the Spirit is in all goodness and righteousness and truth;)” | Goodness listed beside righteousness and truth as the fruit of a life lived in the light |
| 2 Thessalonians 1:11 | “Wherefore also we pray always for you, that our God would count you worthy of this calling, and fulfil all the good pleasure of his goodness, and the work of faith with power:” | Goodness as a desire that needs God’s power to be carried through |
Two small notes for careful readers. In Ephesians 5:9, the oldest Greek manuscripts read “the fruit of the light” rather than “of the Spirit,” which fits Paul’s point in the verse before: “walk as children of light.” And in 2 Thessalonians 1:11, the Greek has no word for “his.” Paul literally prays that God would fulfil “every good pleasure of goodness,” and many modern translations read it as the believers’ own resolve to do good, which God brings to completion.
Verse Deep Dive: Romans 15:14
Paul has just spent fourteen chapters writing the most demanding letter in the New Testament, and near the end he pauses to reassure the church in Rome:
“And I myself also am persuaded of you, my brethren, that ye also are full of goodness, filled with all knowledge, able also to admonish one another.” (Romans 15:14)
Look at the order. Full of goodness. Filled with knowledge. Therefore able to admonish one another. The word for “admonish” is noutheteo, literally “to put in mind,” the word for a warning or a correction spoken face to face. Paul names two things a person needs before they are fit to correct someone else, and goodness comes first.
Think about what happens when one of the two is missing. Knowledge without goodness produces correction that is accurate and cruel. The facts are right, and the person walks away wounded and unchanged. Goodness without knowledge produces a well-meaning friend who never says the hard thing, or says the wrong one. Paul wants a church where people are both, so that when a warning has to be given, it comes from someone whose goodness is not in doubt.
This is why the verse is the key to agathosyne. In English, “goodness” sounds soft, the opposite of confrontation. Paul treats it as the very thing that makes honest confrontation possible. A good person in the Greek sense is not someone who avoids hard conversations. It is someone you can trust when the hard conversation comes, because you already know they are for you.
Not All “Goodness” Is the Same
English uses “good” and “goodness” for several different Greek words. Knowing which one is underneath changes what a verse is saying:
- Agathosyne (ἀγαθωσύνη, G19): the noun this page is about. Active, upright goodness that does good and can be firm when needed.
- Chrestotes (χρηστότης, G5544): the word listed just before it in Galatians 5:22, translated “gentleness” in the KJV and “kindness” in most modern Bibles. It is goodness fitted to the person receiving it, mellow and generous. Our study of chrestotes goes deeper. The 19th-century scholar R.C. Trench, drawing on Jerome, drew the line this way: chrestotes is the kindness that welcomes, while agathosyne is the goodness that may also rebuke and correct. His example was Jesus driving the money-changers out of the temple (Matthew 21:12-13). That was goodness. It was not gentleness.
- Kalos (καλός, G2570): “good” in the sense of fine, beautiful, and admirable to look at. It is the word in “I am the good shepherd” (John 10:11) and in “good works” that others can “see” (Matthew 5:16). Kalos is goodness as it appears; agathos is goodness as it acts.
Romans 5:7 shows the difference between being merely right and being good: “For scarcely for a righteous man will one die: yet peradventure for a good man some would even dare to die.” The “good man” there is agathos. Many commentators read Paul as drawing a line between someone who is correct, who does what is owed, and someone who is good, whose goodness goes beyond what is owed and draws people’s love. For the Old Testament side of this word, see the Hebrew word for goodness, tuv, which pictures goodness as something you can hold and hand to someone.
Why the Original Word Changes the Meaning
In modern English, “good” has been shrunk down to “harmless.” A good kid stays out of trouble. A good neighbour keeps quiet. Goodness is measured by what you avoid.
Agathosyne runs the other direction. It is measured by what it does. That is why Paul can set it right beside chrestotes in Galatians 5:22 without repeating himself. The Spirit grows two kinds of goodness in a person: the kindness that meets people where they are, and the upright goodness that will not leave them there. A life with only the first becomes soft and easily walked over. A life with only the second becomes harsh. The fruit of the Spirit is both, growing on the same branch.
It also means goodness is not a personality type. Some people are naturally agreeable and some are naturally blunt, and neither is agathosyne by default. Paul calls it fruit, which means it grows from somewhere outside you. The goodness God has is the goodness the Spirit grows.
Living It Out
Think of one situation right now where staying quiet would be easier than saying what is true. Before you say anything, run Romans 15:14 in order. First: am I full of goodness toward this person, genuinely for them and not just annoyed with them? Second: do I actually know what I think I know? If both are true, agathosyne may be asking you to speak, gently and clearly. If the first one isn’t true yet, the work starts with prayer, not with the conversation.
Journal Prompts
- Romans 15:14 puts “full of goodness” before “able to admonish.” Think of someone whose correction you actually received well. What did they show you about their goodness before they ever said the hard thing?
- Galatians 5:22 lists chrestotes (kindness) right next to agathosyne (goodness). Which one comes more naturally to you, and where has a lack of the other one cost you or someone you love?
- In 2 Thessalonians 1:11, Paul prays that every “good pleasure of goodness” would be fulfilled “with power.” What good thing have you wanted to do for a long time but never carried through? What would it look like to ask God for the power to finish it?
Prayer
Lord, I confess I have often settled for being harmless and called it good. Grow agathosyne in me, a goodness that acts and does not just avoid. Make me full of goodness before I ever try to correct anyone, so that the people around me know I am for them. Where I am too soft, give me courage. Where I am too sharp, give me kindness. And the good things I have wanted to do and never finished, fulfil them by Your power, as Paul prayed. Let the fruit be Yours, growing in me. Amen.

FAQ
What is the Greek word for goodness in Galatians 5:22?
It is agathosyne (ἀγαθωσύνη), Strong’s G19, pronounced ah-gah-thoh-SOO-nay. It comes from agathos, “good,” and means active, upright goodness. It appears only four times in the New Testament: Romans 15:14, Galatians 5:22, Ephesians 5:9, and 2 Thessalonians 1:11.
What is the difference between goodness and kindness in the fruit of the Spirit?
Kindness (chrestotes) is goodness fitted to the person receiving it, gentle and generous. Goodness (agathosyne) is upright goodness that does what is right for someone, which can include correcting them. Paul lists both side by side because each one needs the other.
Does biblical goodness mean being nice to everyone?
Not exactly. Agathosyne is always for the other person’s good, but that is not the same as always being agreeable. In Romans 15:14, Paul says goodness is what makes believers able to admonish one another. Biblical goodness is warm, but it is also honest.
What is the difference between agathos and kalos?
Both mean “good.” Kalos leans toward what is fine, beautiful, and admirable to see, as in “the good shepherd” (John 10:11). Agathos, the root of agathosyne, leans toward goodness that is beneficial and morally active. Put simply, kalos is goodness as it looks, and agathos is goodness as it acts.
