Matthew Henry
From his Commentary on the Whole Bible. Henry comments on passages, not single verses — this entry covers Luke 11:29–36. His three-level outline is real structure in the source text, so it is rendered as structure.
Christ's discourse in these verses shows two things: -
I.What is the sign we may expect from God for the confirmation of our faith.
The great and most convincing proof of Christ's being sent of God, and which they were yet to wait for, after the many signs that had been given them, was the resurrection of Christ from the dead. Here is,
1.A reproof to the people for demanding other signs than what had already been given them in great plenty: The people were gathered thickly together (Luk 11:29), a vast crowd of them, expecting not so much to have their consciences informed by the doctrine of Christ as to have their curiosity gratified by his miracles. Christ knew what brought such a multitude together; they came seeking a sign, they came to gaze, to have something to talk of when they went home; and it is an evil generation which nothing will awaken and convince, no, not the most sensible demonstrations of divine power and goodness.
2.A promise that yet there should be one sign more given them, different from any that had yet been given them, even the sign of Jonas the prophet, which in Matthew is explained as meaning the resurrection of Christ. As Jonas being cast into the sea, and lying there three days, and then coming up alive and preaching repentance to the Ninevites, was a sign to them, upon which they turned from their evil way, so shall the death and resurrection of Christ, and the preaching of his gospel immediately after to the Gentile world, be the last warning to the Jewish nation. If they be provoked to a holy jealousy by this, well and good; but, if this do not work upon them, let them look for nothing but utter ruin: The Son of Man shall be a sign to this generation (Luk 11:30), a sign speaking to them, though a sign spoken against by them.
3.A warning to them to improve this sign; for it was at their peril if they did not.
(1.)The queen of Sheba would rise up in judgment against them, and condemn their unbelief, Luk 11:31. She was a stranger to the commonwealth of Israel, and yet so readily gave credit to the report she heard of the glories of a king of Israel, that, notwithstanding the prejudices we are apt to conceive against foreigners, she came from the uttermost parts of the earth to hear his wisdom, not only to satisfy her curiosity, but to inform her mind, especially in the knowledge of the true God and his worship, which is upon record, to her honour; and, behold, a greater than Solomon in here, pleion Solomōntos - more than a Solomon is here; that is, says Dr. Hammond, more of wisdom and more heavenly divine doctrine than ever was in all Solomon's words or writings; and yet these wretched Jews will give no manner of regard to what Christ says to them, though he be in the midst of them.
(2.)The Ninevites would rise up in judgment against them, and condemn their impenitency (Luk 11:32): They repented at the preaching of Jonas; but here is preaching which far exceeds that of Jonas, is more powerful and awakening, and threatens a much sorer ruin than that of Nineveh, and yet none are startled by it, to turn from their evil way, as the Ninevites did.
II.What is the sign that God expects from us for the evidencing of our faith, and that is the serious practice of that religion which we profess to believe, and a readiness to entertain all divine truths, when brought to us in their proper evidence. Now observe,
1.They had the light with all the advantage they could desire. For God, having lighted the candle of the gospel, did not put it in a secret place, or under a bushel; Christ did not preach in corners. The apostles were ordered to preach the gospel to every creature; and both Christ and his ministers, Wisdom and her maidens, cry in the chief places of concourse, Luk 11:33. It is a great privilege that the light of the gospel is put on a candlestick, so that all that come in may see it, and may see by it where they are and whither they are going, and what is the true, and sure, and only way to happiness.
2.Having the light, their concern was to have the sight, or else to what purpose had they the light? Be the object ever so clear, if the organ be not right, we are never the better: The light of the body is the eye (Luk 11:34), which receives the light of the candle when it is brought into the room. So the light of the soul is the understanding and judgment, and its power of discerning between good and evil, truth and falsehood. Now, according as this is, so the light of divine revelation is to us, and our benefit by it; it is a savour of life unto life, or of death unto death.
(1.)If this eye of the soul be single, if it see clear, see things as they are, and judge impartially concerning them, if it aim at truth only, and seek it for its own sake, and have not any sinister by - looks and intentions, the whole body, that is, the whole soul, is full of light, it receives and entertains the gospel, which will bring along with it into the soul both knowledge and joy. This denotes the same thing with that of the good ground, receiving the word and understanding it. If our understanding admits the gospel in its full light, it fills the soul, and it has enough to fill it. And if the soul be thus filled with the light of the gospel, having no part dark, - if all its powers and faculties be subjected to the government and influence of the gospel, and none left unsanctified, - then the whole soul shall be full of light, full of holiness and comfort. It was darkness itself, but now light in the Lord, as when the bright shining of a candle doth give thee light, Luk 11:36. Note, The gospel will come into those souls whose doors and windows are thrown open to receive it; and where it comes it will bring light with it. But,
(2.)If the eye of the soul be evil, - if the judgment be bribed and biassed by the corrupt and vicious dispositions of the mind, by pride and envy, by the love of the world and sensual pleasures, - if the understanding be prejudiced against divine truths, and resolved not to admit them, though brought with ever so convincing an evidence, - it is no wonder that the whole body, the whole soul, should be full of darkness, Luk 11:34. How can they have instruction, information, direction, or comfort, from the gospel, that wilfully shut their eyes against it? and what hope is there of such? what remedy for them? The inference hence therefore is, Take heed that the light which is in thee be not darkness, Luk 11:35. Take heed that the eye of the mind be not blinded by partiality, and prejudice, and sinful aims. Be sincere in your enquiries after truth, and ready to receive it in the light, and love, and power of it; and not as the men of this generation to whom Christ preached, who never sincerely desired to know God's will, nor designed to do it, and therefore no wonder that they walked on in darkness, wandered endlessly, and perished eternally.

For He gives the name of the eye especially to our understanding, but the whole soul, although not corporeal, He metaphorically calls the body. For the whole soul is enlightened by the understanding.
For the understanding from its very beginning desires only singleness, containing no dissimulation, or guile, or division in itself.
(Epist. 41.) Or else; The light and eye of the Church is the Bishop. It is necessary then that as the body is rightly directed as long as the eye keeps itself pure, but goes wrong when it becomes corrupt, so also with respect to the Prelate, according to what his state may be, must the Church in like manner suffer shipwreck, or be saved.
Therefore, because in previous passages he preferred the Church to the Synagogue, he exhorts us to rather transfer our faith to the Church; for faith is a lamp, according to what is written: Your word, Lord, is a lamp to my feet; for our faith is the word of God, the word of God is light, and faith is a lamp. There was the true light, which enlightens every person coming into this world. However, a lamp cannot shine unless it receives light from elsewhere. This is the lamp that is lit, namely the power of our mind and senses, so that it can find what was lost. Therefore, let no one establish faith under the Law; for the Law is within a measure, but grace is beyond measure: the Law shadows, grace illuminates. And therefore let no one confine their faith within the measure of the Law, but let them bring it to the Church, in which the grace of the sevenfold Spirit shines forth, which that Prince of priests illumines with the radiance of heavenly divinity, lest the shadow of the Law extinguish it.
Finally, that lamp which the high priest used to light at the times of morning and evening, according to the ancient rite of the Jews, as if placed under a bushel, has disappeared: and that city, Jerusalem, which is on the earth, which killed the prophets, is hidden as if in a valley of tears: but that Jerusalem which is in heaven, in which our faith fights, placed on that highest of all mountains, that is, in Christ, the Church cannot be hidden by the darkness and ruins of this world: but shining with the brightness of the eternal sun, it illuminates us with the light of spiritual grace.
Either faith is the light, as it is written, Thy word, O Lord, is a lantern to my feet. (Ps. 119:105.) For the word of God is our faith. But a lantern cannot shine except it has received its quality from something else. Hence also the powers of our mind and senses are enlightened, that the piece of money which had been lost may be found. Let no one then place faith under the law, for the law is bound by certain limits, grace is unlimited; the law obscures, grace makes clear.
(Hom. 20. in Matt.) If then we have corrupted the understanding, which is able to let loose the passions, we have done violence to the whole soul, and suffer dreadful darkness, being blinded by the perversion of our understanding. Therefore adds he, Take heed, therefore, that the light which is in thee be not darkness. He speaks of a darkness which may be perceived, but which has its origin within itself, and which we every where carry about with us, the eye of the soul being put out. Concerning the power of this light He goes on to say, If thy whole body therefore be full of light, &c. &c.
(de Cons. Ev. lib. ii. c. 39.) Luke indeed relates this in the same place as Matthew, but in a somewhat different order. But who does not see that it is an idle question, in what order our Lord said those things, seeing that we ought to learn by the most precious authority of the Evangelist, that there is no falsehood. But not every man will repeat another's words in the same order in which they proceeded from his mouth, seeing that the order itself makes no difference with respect to the fact, whether it be so or not.
(28. Mor. c. 12.) Or else; By the name body each particular action is understood which follows its own intention, as it were the eye of the spectators. Therefore it is said, The light of the body is the eye, because by the ray of a good intention the deserving parts of an action receive light. If then thy eye be single, thy whole body will be full of light, for if we intend rightly in singleness of heart, we accomplish a good work, even though it seem not to be good. And if thy eye be evil, thy whole body will be full of darkness, because when with a crooked intention even a right thing is done, although it appears to glitter in men's sight, yet before the bar of the internal judge it is covered with darkness. Hence too it is rightly added, Take heed therefore that the light which is in thee be not darkness. For if what we think we do well we cloud by a bad intention, how many are the evils themselves which even when we do them we know to be evil?
If your eye is simple, your whole body will be full of light. But if it is evil, your body also will be full of darkness. He said, if you strive to do good with a pure and upright intention, the works that you do are indeed works of light, even if they seem to have some imperfection in the sight of men. Because for those who love God, all things work together for good, for those who are called according to His purpose. But if the preceding intention is perverse, every work that follows is of little value, even if it seems to be correct.
Our Lord here speaks of Himself, showing that although He had said above that no sign should be given to this wicked generation but the sign of Jonas, yet the brightness of His light should by no means be hid from the faithful. He Himself indeed lights the candle, who filled the vessel of our nature with the fire of His divinity; and this candle surely He wished neither to hide from believers, nor to place under a bushel, that is, enclose it in the measure of the law, or confine it within the limits of the single nation of the Jews. But He placed it upon a candlestick, that is, the Church, for He has imprinted on our foreheads the faith of His incarnation, that they who with a true faith wish to enter the Church, might be able to see clearly the light of the truth. Lastly, He bids them remember to cleanse and purify not only their works, but their thoughts, and the intentions of the heart. For it follows, The light of the body is the eye.
Now when He adds, If thy whole body therefore, &c. by the whole of our body He means all our works. If then thou hast done a good work with a good intention, having in thy conscience nothing approaching to a dark thought, though it chance that thy neighbour is injured by thy good actions, nevertheless for thy singleness of heart shalt thou be rewarded with grace here, and with glorious light hereafter; which he signifies, adding, And as the bright shining of a candle shall it give thee light. These words were especially directed against the hypocrisy of the Pharisees, who sought for signs that they might catch him.
The lamp of your body is your eye. By body, He means the works that appear openly to all; indeed, the eye itself performs the intention of the mind, and by its merit, these works are discerned as works of light or darkness, as He Himself subsequently explained, saying:
What else does he mean by “the eye” than simply the mind, which will never become simple unless it contemplates the simple light? The simple light is Christ. He who has his light shining in his mind is said to have the mind of Christ. When your light is this simple, then the whole immaterial body of your soul will be full of light. If the mind is evil, that is, darkened and extinguished, then this body of yours will be full of darkness.…We say, “See to it, brothers, that while we seem to be in God and think that we have communion with him we should not be found excluded and separated from him, since we do not now see his light.” If that light had kindled our lamps, that is, our souls, it would shine brightly in us. Our God and Lord Jesus Christ said, “If your whole body is full of life, having no dark part, it will be wholly bright, as when a lamp with its rays gives you light.” What other witness greater than this shall we adduce to make the matter clear to you? If you disbelieve the Master, how will you, tell me, believe your fellow servant?
Or else, because the Jews, seeing the miracles, accused them out of the malice of their heart, therefore our Lord tells them, that, receiving the light, that is, their understanding, from God, they were so darkened with envy, as not to recognise His miracles and mercies. But to this end received we our understanding from God, that we should place it upon a candlestick, that others also who are entering in may see the light. The wise man indeed has already entered, but the learner is still walking. As if He said to the Pharisees, You ought to use your understanding to know the miracles, and declare them to others, seeing that what you see are the works not of Beelzebub, but the Son of God. Therefore, keeping up the meaning, He adds, The light of the body is the eye.
But as if the eye of the body be light the body will be light, but if dark the body will be dark also, so is it with the understanding in relation to the soul. Hence it follows, If thine eye be single, thy whole body will be full of light; but if evil, thy whole body will be full of darkness.

Summary
Luke 11:34 presents Jesus' teaching on the profound connection between one's inner spiritual disposition and their outward life, using the metaphor of the eye as the body's lamp. Just as a healthy eye allows light to fill the body, a "single" or sincere spiritual focus leads to a life characterized by truth and clarity. Conversely, an "evil" or self-centered eye results in spiritual darkness, obscuring one's moral and spiritual path and leading to actions rooted in confusion and sin. This verse underscores the critical importance of cultivating an internal state of purity and right intention, as it dictates the spiritual illumination or obscurity of one's entire being.
Context
Literary Context
This verse is situated within a series of teachings by Jesus in Luke 11. Immediately preceding it, Jesus has just responded to accusations that He casts out demons by the power of Beelzebul (Luke 11:14-23), and He has delivered the "sign of Jonah" teaching, emphasizing that His presence and words are the ultimate sign, not miraculous displays (Luke 11:29-32). The verses following this one discuss the importance of not hiding one's light (Luke 11:33) and then launch into a series of woes against the Pharisees and lawyers for their hypocrisy and spiritual blindness (Luke 11:37-54). Thus, Luke 11:34 serves as a pivotal bridge, moving from the external demand for signs to the internal condition of spiritual perception and the moral implications of one's inner state. It highlights that true understanding and spiritual light come from within, not merely from outward observation.
Historical & Cultural Context
In the ancient world, the eye was commonly understood as the primary organ through which light entered the body, enabling perception and navigation. This physical reality provided a natural metaphor for spiritual understanding. The concept of the "evil eye" (Greek: ophthalmos poneros) was widespread in the ancient Near East and Mediterranean cultures, often associated with envy, covetousness, malice, or a grudging spirit that could bring harm or misfortune to others. Conversely, a "good eye" or "single eye" (Greek: ophthalmos haplous) was understood to signify generosity, sincerity, integrity, and a clear, unmixed intention. Jesus' audience, familiar with these cultural idioms, would have readily grasped the spiritual implications: one's inner disposition, particularly regarding wealth and generosity (as seen in the parallel passage in Matthew 6:22-23), profoundly affects their entire spiritual and moral outlook.
Key Themes
This verse contributes significantly to several key themes in Luke's Gospel and Jesus' broader teaching. It emphasizes spiritual discernment and the holistic nature of human existence, where inner intentions profoundly shape outward actions. The contrast between light and darkness is a pervasive biblical theme, representing truth, purity, and God's presence versus sin, ignorance, and spiritual blindness. Jesus consistently calls for a purity of heart and a singular devotion to God, warning against divided loyalties (e.g., Luke 16:13). This teaching also foreshadows the woes against the Pharisees, whose external righteousness masked an internal "evil eye" of hypocrisy and self-interest, leading to spiritual darkness despite their religious observance. Ultimately, Luke 11:34 underscores that true spiritual illumination stems from an uncorrupted inner disposition, aligned with God's will and generosity.
Exposition and Analysis
Key Word Analysis
From the base of λευκός (leukos), meaning "white" or "bright," lýchnos refers to a portable lamp or other illuminator. In this context, it functions metaphorically to describe the eye's role in allowing spiritual insight or understanding to enter and illuminate the entire person, much like a lamp lights a room.
Probably from a particle of union (A) and the base of πλέκω (plekō, "to plait" or "fold"), haploûs literally means "folded together" or "simple." Figuratively, it conveys the idea of being clear, sincere, undivided, generous, or healthy in one's intentions and focus. A "single eye" implies an unmixed, pure, and healthy spiritual outlook.
From a derivative of πόνος (ponos, "to toil" or "labor"), ponērós signifies something hurtful, evil, or malicious, particularly in its effect or influence. It contrasts with kakos (which refers to essential character) and sapros (degeneracy). In the context of the eye, ponērós refers to a diseased, jaundiced, covetous, or malevolent outlook, leading to harmful spiritual consequences.
Verse Breakdown
"The light of the body is the eye:"
This opening clause establishes the central metaphor. Just as the physical eye is the conduit through which light enters to enable the body to navigate and perceive the physical world, so too is the spiritual "eye"—representing our inner focus, intention, or spiritual perception—the conduit through which spiritual truth and light enter our being. It highlights the eye's critical function as the gateway to illumination.
"therefore when thine eye is single, thy whole body also is full of light;"
Following the initial premise, Jesus presents the positive consequence of a healthy spiritual "eye." If one's inner focus is "single" (haplous), meaning sincere, undivided, generous, or pure in intention, then the entire person ("thy whole body") will be "full of light." This signifies a life characterized by spiritual clarity, truth, righteousness, and moral integrity, where actions and thoughts are illuminated by divine wisdom.
"but when [thine eye] is evil, thy body also [is] full of darkness."
This clause presents the stark contrast and negative consequence. If one's inner focus or intention is "evil" (poneros), implying a covetous, malicious, selfish, or grudging disposition, then the entire person will be "full of darkness." This indicates a life dominated by spiritual blindness, moral confusion, sin, and a lack of divine insight, where actions are driven by corrupt motives and lead to spiritual decay.
Literary Devices
Luke 11:34 is rich in literary devices that enhance its impact and clarity. The primary device is Metaphor, where the physical eye is used to represent one's inner spiritual disposition, intention, or worldview. This metaphor extends to the "light" and "darkness" that fill the body, symbolizing spiritual understanding and righteousness versus spiritual ignorance and sin. The verse also employs striking Antithesis, presenting a clear contrast between the "single" eye and the "evil" eye, and their respective outcomes: being "full of light" versus being "full of darkness." This stark opposition emphasizes the critical choice and its profound consequences. Furthermore, Symbolism is evident in the use of "light" and "darkness" as traditional biblical symbols for good/evil, truth/falsehood, and divine presence/spiritual absence. The "eye" itself becomes a symbol for one's inner moral and spiritual compass, highlighting the internal source of external behavior.
Theological and Thematic Connections
This verse profoundly impacts our understanding of spiritual life, emphasizing that true spiritual health originates from an internal disposition rather than external circumstances or rituals. It underscores the holistic nature of humanity, where the inner "eye" or heart's condition directly dictates the spiritual state of the entire person. Theologically, it aligns with the biblical emphasis on the purity of heart as foundational to seeing God and living righteously. It challenges believers to cultivate an undivided focus on God, a generous spirit, and sincere intentions, recognizing that a corrupted inner life inevitably leads to spiritual darkness and moral decay. This teaching serves as a powerful call to self-examination and repentance, urging us to guard our hearts and minds, for they are the wellspring of life.
Reflection and Application
Luke 11:34 serves as a timeless and piercing reminder that our inner world profoundly shapes our outer reality. In an age saturated with information and distractions, where our "eye" is constantly bombarded by various inputs, Jesus' words challenge us to consider what we are allowing to inform our perspective. Is our inner "eye" fixed on truth, generosity, and the things of God, leading to a life "full of light"? Or is it consumed by selfishness, covetousness, envy, or the fleeting concerns of the world, plunging us into spiritual "darkness"? This verse calls for intentional spiritual discipline: to guard our hearts, to be discerning about what we consume (mentally, emotionally, spiritually), and to cultivate a pure and undivided devotion to Christ. It means actively choosing to see the world through God's lens, seeking His kingdom first, and allowing His light to illuminate every aspect of our lives, transforming our character and actions.
Questions for Reflection
FAQ
What does Jesus mean by the "single eye" (ἁπλοῦς - haplous)?
The "single eye" refers to a spiritual disposition that is pure, sincere, undivided, and generous. It implies a clear, unmixed intention, often contrasted with a double-mindedness or a focus on worldly gain. In the parallel passage in Matthew 6:22-23, this concept is directly linked to one's attitude towards money and serving God, suggesting that a "single eye" is one that is not covetous but rather focused on heavenly treasures and God's will. It signifies spiritual health and integrity, leading to a life filled with spiritual light and clarity.
What does the "evil eye" (πονηρός - ponērós) signify in this context?
The "evil eye" signifies a spiritual disposition that is corrupted, malicious, covetous, or grudging. It represents an inner state characterized by selfishness, envy, or a jaundiced view of others and the world. This is not merely about physical sight but about one's inner intentions and moral outlook. When the "eye" is "evil," it means one's spiritual perception is clouded by sin and self-interest, leading to a life "full of darkness"—marked by moral confusion, unrighteous actions, and spiritual blindness. It is the opposite of the generous and pure "single eye."
How does this teaching relate to physical vision or blindness?
While Jesus uses the physical eye as a metaphor, His teaching in Luke 11:34 is primarily about spiritual vision and the inner state of a person, not physical sight. Just as a healthy physical eye enables one to navigate the physical world, a healthy spiritual "eye" enables one to perceive and navigate the spiritual and moral realities of God's kingdom. The physical analogy helps to illustrate the profound impact of one's inner disposition on their entire being, whether leading to spiritual clarity ("full of light") or spiritual confusion and sin ("full of darkness"). The verse underscores that true spiritual understanding and righteousness flow from an uncorrupted heart and a singular focus on God.
Christ-Centered Fulfillment
Luke 11:34 finds its ultimate fulfillment in Jesus Christ, who is the very "light of the world" (John 8:12). Our "eye" being "single" means fixing our gaze upon Him, for in Him alone is perfect clarity, truth, and spiritual illumination. He is the one who reveals the Father (John 14:9) and brings us out of darkness into His marvelous light (1 Peter 2:9). The "evil eye" represents the fallen human condition, blinded by sin and self-interest, unable to perceive spiritual truth. But through Christ's atoning sacrifice, our spiritual eyes are opened, and our hearts are cleansed, enabling us to see God and His kingdom with a "single" and pure intention. As believers, we are called to reflect His light, becoming lamps ourselves (Matthew 5:14-16), shining forth the truth and love of Christ into a world still shrouded in darkness, all because our "eye" is fixed on Him, the source of all light.
