Matthew 6:23 Commentary: The Darkened Eye of a Divided Heart
Greek · 9 what the commentators say
Meaning in one sentence
Discover what Jesus means by 'the light that is in you is darkness' and how a covetous heart blinds us to God's kingdom.
Research Summary
- Meaning: A covetous or divided heart blinds a person to spiritual truth, turning the very faculty of discernment into a source of deeper darkness.
- Key words: πονηρός (ponēros, evil/bad), describes the moral corruption of the eye; σκότος (skotos, darkness), not just absence of light but active darkness of ignorance and self-deception.
- Main debate: Whether the 'evil eye' refers primarily to greed (Barnes, Gill, Matthew Henry) or to any twisted use of reason that leads to moral blindness (Calvin). Both agree it involves a heart that claims to see but is lost.
- Theological theme: Human depravity cannot be self-corrected; the very instruments we rely on (mind, conscience) can become corrupted. Salvation requires an external light, Christ.
- Best use: A searching call to examine hidden motives, especially in relation to money and possessions, given the immediate context of serving God and mammon.

Mas si tu ojo fuere malo, todo tu cuerpo será tenebroso. Así que, si la lumbre que en ti hay son tinieblas, ¿ cuántas serán las mismas tinieblas?
Porém se o teu olho for maligno, todo o teu corpo será cheio de trevas. Assim, se a luz que há em ti são trevas, como são grandes essas trevas!
mais si ton œil est en mauvais état, tout ton corps sera dans les ténèbres. Si donc la lumière qui est en toi est ténèbres, combien seront grandes ces ténèbres!
ist aber dein Auge ein Schalk, so wird dein ganzer Leib finster sein. Wenn nun das Licht, das in dir ist, Finsternis ist, wie groß wird dann die Finsternis sein!
Maar indien uw oog boos is, zo zal geheel uw lichaam duister zijn. Indien dan het licht, dat in u is, duisternis is, hoe groot zal de duisternis zelve zijn!
ma se l’occhio tuo è viziato, tutto il tuo corpo sarà nelle tenebre. Se dunque la luce che è in te è tenebre, esse tenebre quanto grandi saranno!
Jeźliby zaś oko twoje złe było, wszystko ciało twoje ciemne będzie; jeźli tedy światłość, która jest w tobie, ciemnością jest, sama ciemność jakaż będzie?
если же око твое будет худо, то все тело твое будет темно. Итак, если свет, который в тебе, тьма, то какова же тьма?
你的 眼睛 若 昏花， 全 身 就 黑暗。 你 裡頭 的光 若 黑暗了，那黑暗 是何等大呢！」
But if your eye is evil, all your body will be dark. If then the light which is in you is dark, how dark it will be!

Scholars' Consensus
Commentators agree that this verse warns about a spiritual condition masked as seeing. The 'evil eye' (ὀφθαλμὸς πονηρός) in Jewish idiom refers to a stingy, covetous disposition, the opposite of the 'healthy' or 'single' eye. Barnes notes that when the eye is diseased, the whole body walks in darkness; so when the soul's gaze is fixed on earthly treasure instead of heaven, every action is confused and misdirected. Gill specifies that covetousness enslaves the mind, darkening judgment and leading to irrational choices. Calvin broadens the 'light within' to include whatever dim reason remains after the fall, which people twist into self-serving cunning, so the very faculty meant to guide becomes a source of deeper darkness. The shared thrust: a person can think they are spiritually discerning while actually being ruled by greed or pride. That self-deception is the most dangerous darkness of all.
How settled is the interpretation?
Interpretive difficulty: Medium
Main views:
- Covetousness (Barnes, Gill, Matthew Henry): The immediate context (vv.19–21, 24) about treasure and serving money, plus the Jewish idiom 'evil eye' for stinginess.
- Moral perversity (Calvin): The 'light' as fallen reason twisted into cunning self-destruction; cross-reference to Isaiah 5:20 and 44:20.
- Self-deceived wisdom (Proverbs 26:12 connection): The verse's structure parallels warnings against those wise in their own eyes; the 'light' becomes darkness through pride.
What is clear: The verse warns that a person's inner faculty for discernment can become corrupted, leaving them in a state of active self-deception from which they cannot escape on their own.
What Scholars Agree and Debate
| Topic | Agreed | Debated |
|---|---|---|
| Meaning of the 'evil eye' | All commentators see it as a metaphor for a corrupt inner disposition, not a physical condition. | Some (Barnes, Gill) stress covetousness specifically; Calvin includes any perversion of reason into cunning selfishness. |
| The identity of 'the light that is in you' | It refers to the human capacity for understanding, conscience, or spiritual insight, the faculty that should guide behavior. | Calvin limits it to 'that small portion of reason which continues after the fall'; others see it as the entire moral and spiritual awareness. |
| Connection to serving two masters (v.24) | The passage is a single unit: the eye metaphor explains why a divided heart (God and money) is impossible. | Some (Lange) note debate over whether vv.22, 23 were originally connected to vv.19, 21, but none question the editorial connection in Matthew. |
| The severity of the warning | This is one of the most sobering statements in the Sermon on the Mount, a warning about final and total darkness. | Whether the result is temporal confusion leading to repentance, or eternal judgment (Gill takes the latter view; others are less specific). |
Historical & Cultural Context
Jesus draws on a common ancient metaphor. The eye was considered the body's lamp, it admits light and directs motion. In first-century Jewish culture, the phrase 'evil eye' (ayin hara' in Hebrew) specifically denoted envy or stinginess, while a 'good eye' meant generosity. This appears in Proverbs 23:6 ('do not eat the bread of a stingy man') and is elaborated in rabbinic literature. So when the hearers of the Sermon on the Mount heard 'eye is evil,' they would have immediately thought of covetousness.
The passage sits between the command to store treasure in heaven (vv.19, 21) and the declaration that no one can serve both God and money (v.24). Verses 22, 23 act as a hinge: they explain how the divided heart works. A person who claims to be devoted to God while secretly clinging to wealth has something wrong with their inner vision. They may still perform religious duties (as the earlier warnings about hypocrisy in chapter 6 show), but their fundamental orientation is corrupted. Jesus presses the point to an uncomfortable conclusion: such a person does not simply lack light; their supposed light has turned into darkness. That is not a state of ignorance but of active self-deception, the kind the prophets denounced (Isaiah 5:20, 44:18, 20). The warning is stark: if your guiding faculty is itself blinded, you have no way to correct your course.
Textual Notes
The consulted sources note no significant textual variants for this verse. The Greek text is stable across major manuscript families, and the translation is uniform across modern versions (WEB, KJV, ASV, BSB, YLT).
Reception History
Early church writers like Chrysostom read the ‘evil eye’ as envy and greed, using the verse to confront the love of money in wealthy congregations. In the medieval period, the verse was cited in discussions of the capital sin of avarice and linked with the eye of the soul that should be fixed on God. Reformers (Calvin, Luther) emphasized the total corruption of human reason: even what seems like light in fallen humanity can be darkness. Puritan commentators like Matthew Henry expanded the application to hypocrisy in religious practice, warning that a person can appear devoted while their heart is set on earthly gain. In modern evangelical preaching, this verse is often used in series on money and stewardship, paired with the call to store up treasure in heaven.
Preaching This Verse
Three-point outline
- The eye determines what you see. Just as a healthy eye lets the body walk in light, the soul’s focus, treasure in heaven or on earth, determines whether your life reflects God or greed.
- The evil eye is a condition, not a mistake. Covetousness is not a simple error; it is a moral corruption that darkens the very capacity to discern right from wrong. As Barnes said, avarice ‘darkens the mind, obscures the view’ until nothing is seen clearly.
- A darkened ‘light’ is the worst darkness. When the faculty you trust to guide you (reason, conscience, religious experience) itself becomes twisted, you have no reference point left. The self-deceived person cannot even diagnose their own blindness.
Five-point outline
- The metaphor: eye as lamp of the body (v.22a).
- The healthy eye: whole body full of light (v.22b).
- The evil eye: whole body full of darkness (v.23a).
- The shock: the light within you becomes darkness (v.23b).
- The application: you cannot serve both God and money (v.24).
Illustration hooks
- A GPS that guides you into a lake. If your navigation system is faulty, you trust it right up to the moment of disaster. When our internal ‘light’ (conscience, ambition, sense of purpose) is corrupted by greed, it leads us confidently into ruin.
- The person who insists their tinted glasses let them see perfectly. They argue that everything looks fine, but they cannot see the colour of the sky or the faces of passers-by. A heart devoted to wealth can justify any choice and still believe it follows God.
- Crossing a river on a log. Barnes used the example of looking only at the opposite bank, fixing your eyes on the goal. If you look down at the swirling water, you get dizzy and fall. An divided eye makes the whole life unsteady.
Questions your congregation is asking
- “I go to church and give offerings, am I really serving money too?”
- “How do I know if my heart is divided? What are the signs of an ‘evil eye’ in everyday life?”
- “If I am unsure whether my ‘light’ is darkness, how do I find out, and what do I do?”
Leading a Discussion
This verse forces us to examine what we truly treasure. Jesus does not leave room for a comfortable middle ground: either your eye is single, fixed on God’s kingdom, or it is evil, and your whole life is walking in darkness. The hardest part is that we can feel like we are seeing clearly while actually being deceived. Use these questions to help your group look honestly at their own hearts.
Discussion questions
- What does the image of the eye as a ‘lamp’ suggest about how our inner focus affects our whole life?
- In Jewish culture an ‘evil eye’ meant stinginess or envy. How does that meaning fit with the surrounding passage about treasure and serving two masters?
- Read verse 23 again: ‘If therefore the light that is in you is darkness, how great is the darkness!’ What do you think ‘the light that is in you’ refers to, your conscience, your reason, your spiritual understanding?
- Calvin said that even our natural reason can be twisted into ‘craft’ for selfish ends. Can you think of a time when a seemingly good intention (providing for family, being responsible) actually masked a covetous heart?
- How does self-deception differ from simple ignorance? Why is it more dangerous?
- Share a situation where you had to choose between a ‘heavenly’ and an ‘earthly’ treasure. How did you know which one you were actually pursuing?
- What practical step could you take this week to ‘fix your eye’ more steadily on Christ rather than on what you own or want?

What the Commentators Say
9 public-domain commentaries, condensed into plain language.
Barnes' Notes on the Bible Protestant 1832
Barnes illustrates the principle of spiritual focus with everyday examples: rope-dancers who steady themselves by looking at a fixed point, or someone crossing a stream on a log. He argues that the soul is like an eye, and when it is fixed single-mindedly on heaven, the whole conduct becomes steady and clear. If that inner light is darkened by earthly attachments, the resulting confusion is worse than physical blindness.
Calvin's Commentaries Reformed 1564
Calvin identifies the light as the small measure of reason left after the fall, and darkness as the brutal passions that overwhelm it. His point is that when people choose willful blindness, they corrupt even this remaining wisdom, turning it into craftiness and self-destruction rather than restraint.
Cambridge Bible for Schools and Colleges Anglican 1880
The commentator stresses that the Greek word translated "light" is accurate, but the real issue is not the light itself—it is the diseased medium through which that light enters. When the body's spiritual perception is corrupted, even genuine light becomes overwhelming darkness.
Geneva Bible Notes Reformed 1599
The Geneva note stresses the devastating progression that follows a corrupt spiritual eye: it does not just dim the body but plunges it into total darkness. The worst condition, the note says, is when the light within a person becomes darkness itself, for that darkness is far greater than ordinary ignorance.
Gill's Exposition of the Bible Baptist 1748
Gill identifies the evil eye with covetousness, a dominant sin that clouds all judgment. This greedy disposition enslaves the mind's faculties, making a person unable to discern what is right before God or others. The resulting darkness is total and leads to misery unless grace intervenes.
Jamieson-Fausset-Brown Commentary Protestant 1871
JFB argues that an evil eye means a heart divided between heaven and earth, making the whole inner life dark. Since the conscience and a person's single-minded aim determine character, a distorted, double purpose darkens every other faculty and principle, leaving the entire person in darkness.
Lange's Commentary Reformed 1857
Lange argues that the Pharisees' false spirituality is actually a sophisticated form of worldliness. Their attempt to serve both God and mammon produces a "moral double sight"—an evil eye that turns the light of revelation into darkness. This hidden worldliness, he contends
Matthew Henry's Commentary Reformed/Presbyterian 1710
Matthew Henry sees worldly-mindedness as a dangerously subtle form of hypocrisy, one that lets Satan grip the soul even while a person maintains a respectable religious profession. He frames the passage as three connected choices every person makes: what treasure to store, what end to pursue, and which master to serve.
Vincent's Word Studies Evangelical 1887
Vincent draws on Seneca's story of a blind slave who blamed the darkness, then on Ruskin's sharper insight: false seeing is worse than blindness. A person unaware of his own spiritual delusion wanders without a guide, mistaking the ditch for the road and the road for the ditch.
