wrong, how do you suppose light fills the body?and Jesus spoke of the light that is IN you. That is all we need for the clarity. This light in men is a spiritual aspect of God who is Light shining in their hearts. The true Light lighteth every man that cometh into the world. If men love the light and come to the light their deeds will be known if they are wrought in God or not. God works in all believers and God is light. His light is how we walk through darkness. His Light shines in our spirit. He lights our candle.
1 John 1:5
"This then is the message which we have heard of him, and declare unto you, that God is light, and in him is no darkness at all."
God dwells in all believers,
1 Corinthians 3:16
"Know ye not that ye are the temple of God, and that the Spirit of God dwelleth in you"
John 3:21
"But he that doeth truth cometh to the light, that his deeds may be made manifest, that they are wrought in God."
The very verse you quote proves you wrong.
1 John 1:5
"This then is the message which we have heard of him, and declare unto you, that God is light, and in him is no darkness at all."
Therefore the light spoken of in Matt 6:23 cannot be the light of Christ or of God -
"If therefore the light that is in thee be darkness, how great is that darkness!"
I have already shown you the meaning of Matt 6:22-23, so I will now leave it to the theologians to explain this verse to you in more detail. Needless to say I couldn't find a single commentator who agrees with your view that the light in the passage is the light of Christ in you.
John Abbott
Verse 22
The light of the body; that is, the instrument or organ on which the body depends for light.--Single; in a healthy and perfect state.--Full of light; fully supplied with light.
Verse 23
Evil; defective or diseased.--If therefore, the light, &c. The meaning of the whole passage is this: As the whole body is in darkness if the light of the eye be extinguished, so, if the perception of divine truth is lost, the whole soul is involved in the deepest spiritual ignorance and danger.
John Calvin
Verse 23
23.If the light which is in thee be darkness Light signifies that small portion of reason, which continues to exist in men since the fall of Adam: and darkness signifies gross and brutal affections. The meaning is, we ought not to wonder, if men wallow so disgracefully, like beasts, in the filth of vices, for they have no reason which might restrain the blind and dark lusts of the flesh. The light is said to be turned into darkness, not only when men permit the wicked lusts of the flesh to overwhelm the judgment of their reason, but also when they give up their minds to wicked thoughts, and thus degenerate into beasts. For we see how wickedly men change into craft any measure of wisdom which had been given them, how they “dig deep (as the prophet says) to hide their counsel from the Lords” (Isaiah 29:15,) how they trust to their own resources, and openly dishonor God; in a word, how desirous they are to show their ingenuity, in innumerable ways, for their own destruction. Christ has good grounds for declaring, that thick and appalling darkness must of necessity reign in the life of men, when they choose to be blind.
This is also the meaning of the words which are found in the Gospel of Luke, with this difference, that Christ there connects the present statement with one which was formerly explained, that men do not light a candle, and put it under a bushel, (Matthew 5:15) and again, instead of this clause, if the light which is in thee be darkness, gives the exhortation, see that the light which is in thee be not darkness The meaning is, “See that thy mind, which ought to have shone, like a candle, to guide all thy actions, do not darken and mislead thy whole life.” He afterwards adds, that, when the body is enlightened by the eye, the greatest regularity is found in all its members, as the light of a candle spreads and penetrates into every part of the room.
Verse 24
24.No man can serve two masters Christ returns to the former doctrine, the object of which was to withdraw his disciples from covetousness. He had formerly said, that the heart of man is bound and fixed upon its treasure; and he now gives warning, that the hearts of those who are devoted to riches are alienated from the Lord. For the greater part of men are wont to flatter themselves with a deceitful pretense, when they imagine, that it is possible for them to be divided between God and their own lusts. Christ affirms that it is impossible for any man to obey God, and, at the same time, to obey his own flesh. This was, no doubt, a proverb in common use: No man can serve two masters He takes for granted a truth which had been universally admitted, and applies it to his present subject: where riches hold the dominion of the heart, God has lost his authority. True, it is not impossible that those who are rich shall serve God; but whoever gives himself up as a slave to riches must abandon the service of God: for covetousness makes us the slaves of the devil.
I have inserted here what is related on a different occasion by Luke: for, as the Evangelists frequently introduce, as opportunity offers, passages of our Lord’s discourses out of their proper order, we ought to entertain no scruple as to the arrangement of them. What is here said with a special reference to riches, may be properly extended to every other description of vice. As God pronounces everywhere such commendations of sincerity, and hates a double heart, (1 Chronicles 12:23,) all are deceived, who imagine that he will be satisfied with the half of their heart. All, indeed, confess in words, that, where the affection is not entire, there is no true worship of God: but they deny it in fact, when they attempt to reconcile contradictions. “I shall not cease,” says an ambitious man, “to serve God, though I devote a great part of my mind to hunting after honors.” The covetous, the voluptuaries, the gluttons, the unchaste, the cruel, all in their turn offer the same apology for themselves: as if it were possible for those to be partly employed in serving God, who are openly carrying on war against him. It is, no doubt, true, that believers themselves are never so perfectly devoted to obedience to God, as not to be withdrawn from it by the sinful desires of the flesh. But as they groan under this wretched bondage, and are dissatisfied with themselves, and give nothing more than an unwilling and reluctant service to the flesh, they are not said to serve two masters: for their desires and exertions are approved by the Lord, as if they rendered to him a perfect obedience. But this passage reproves the hypocrisy of those who flatter themselves in their vices, as if they could reconcile light and darkness.
Charles Ellicott
Verse 22
(22) The light of the body.-Literally, the lamp of the body. So in Proverbs 20:27, “The spirit of man is the candle (or ‘lamp’) of the Lord”—that which, under the name of “conscience,” the “moral sense,” the “inner man” discerns spiritual realities, distinguishes right from wrong, gives the light by which we see our way. If this is “single,” if it discerns clearly, all is well. The “whole body,” the life of the man in all its complex variety, will be illumined by that light. The connection with what precedes lies on the surface. Singleness of intention will preserve us from the snare of having a double treasure, and therefore a divided heart.
Verse 23
(23) If thine eye be evil.—If the spiritual faculty, whose proper work it is to give light, be itself diseased—if it discerns not singly but doubly, and therefore dimly—then the whole life also is shrouded in gloom. If that is the case with the higher life, what will be the state of the lower! If the light is darkened, what will be the state of the region of life which is in itself naturally dark—the region of appetites and passions, which needs the presence of the light to keep them at all in check! “If the light that is in thee be darkness, the darkness how great will it be!”
Leon Morris (1992).
22. We find the little section on the eye difficult; we no longer speak of the “single” or the “evil”70 eye; therefore the meaning is not at all obvious to us. But the eye is a useful illustration of spiritual possibilities. When the eye is functioning normally, the light it perceives means illumination of benefit to the whole body. All sorts of bodily functions may then be performed satisfactorily. There is a spiritual parallel. Jesus speaks of the eye as the light of the body. The meaning appears to be that the eye is the organ that means light to the body; whether we are sighted or blind depends entirely on the eye. The eye is the source of light to the whole body. Apart from the eye the body would receive no light; thus the eye functions much as a lamp does. It is therefore important that the eye be healthy,72 singly concentrating on its proper function. In that case the proper functioning of one small member means illumination for the whole body.
23. The contrary supposition is that the eye is evil, which presumably means that it is diseased or impaired in some way. An eye that is not functioning properly does not bring to the body the benefit of light and, lacking a healthy eye, the whole body is envisaged as in darkness. Nothing can compensate for the lack of light at the one point of entrance. If therefore74 brings out the consequence of all this. Granted that the entrance of light is so important, then, there is disaster if the light within anyone is in fact darkness. Such a person may well think he has light, but to walk in darkness is to lack vision, to demonstrate that one has no light. Filson comments, “If man divides his interest and tries to focus on both God and possessions, he has no clear vision, and will live without clear orientation or direction. Life not focused on God’s claim and command is lost in spiritual darkness.”
The climax of this saying is concerned with the spiritual rather than the physical meaning of vision; the light that is in you is surely not the light that strikes the eye. We might call it the brightness of goodness within. Perhaps we should think of something like “the eye of the soul”; just as a healthy physical eye means illumination for the bodily functions, so a healthy eye of the soul means enlightened living. Jesus is talking about the enlightenment that comes to the person who lives close to God. When that light is darkness there is disaster! Jesus is supposing that where there should be light in a person there is in fact darkness, a perversion at the very heart and center of the person’s life, a complete lack of vision. When that happens, “the darkness—how great!”
John Gill
Verse 22
The light of the body is the eye,.... Or, the "candle of the body is the eye"; for the eye is that in the body, as a candle is in the house; by the light of it, the several members of the body perform their office; and what is said of the eye of the body, is transferred to the eye of the mind:
if therefore thine eye be single: that is, if thy mind be liberal, generous, and bountiful: for Christ is still upon the same subject of liberality, and against covetousness; and here speaks entirely in the language of the Jews, who could easily understand him; in whose writings we read of three sorts of eyes; a good eye, a middling one, and an evil one; so in the offerings of the first fruitsF19,
עין יפה, "a good eye" gave the fortieth, the house Shammai say, the thirtieth part; a middling one, the fiftieth; and an evil one, the sixtieth part.'
Upon which the commentators sayF20, a "good eye" means one that is liberal, and an "evil eye" the contrary: hence you often readF21 of "trading, dedicating", and "giving with a good" or "an evil eye"; that is, either generously, liberally, or in a niggardly and grudging manner; which may help us to the sense of our Lord in these words; whose meaning is, that if a man is not covetous, but his mind is disposed to generosity and liberality; if this be the case, as if he should say,
thy whole body shall be full of light: all thy actions will be influenced by this noble principle; thy whole life will be illuminated, guided and governed by it; thy mind will be cheerful and pleasant, and thy estate and condition will be prosperous and successful.
Verse 23
But if thine eye be evil,.... If thou art of a sordid disposition, of an avaricious temper, if the sin of covetousness prevails over thee,
thy whole body will be full of darkness: thy judgment will be so influenced by that sordid principle, that thou wilt not be able to discern what is agreeable to the law of God, or human reason; what is fitting to be done for thyself, for God, or for thy fellow creatures; all the powers and faculties of thy soul will be enslaved by it, and all be intent upon, and employed in the gratification of it: thy mind will be always sad and sorrowful, harassed and distressed; and thy estate, and condition, will be most miserable and uncomfortable:
if therefore the light that is in thee be darkness, how great is that darkness! as it is in the body, so it is with the mind; as when the eye, the light of the body, is put out by any means, all the members of the body are in entire darkness; so when the light of reason in the mind is so far extinguished by any prevailing iniquity, particularly the sin of covetousness, so that it is wholly influenced and governed by it, what irregular actions is it led into! What deeds of darkness does it perform! and what will be the consequence of it, but utter and eternal darkness, if grace prevent not!
Henry Alford (1863)
Verse 22-23
22, 23. ὁ λύχνος] as lighting and guiding the body and its members: not as containing light in itself. Similarly the inner light, the conscience, lights the spirit and its faculties, but by light supernal to itself.
ἁπλοῦς, clear, untroubled in vision, as the eye which presents a well-defined and single image to the brain. πονηρός, perverse, as the eye which dims and distorts the visual images. φωτεινὸς … σκοτεινός: in full light, as an object in the bright sunshine; in darkness, as an object in the deep shade. The comparison is found in Aristotle. Topic, i. 14 (Wets(81).), ὡς ὄψις ἐν ὀφθαλμῷ, νοῦς ἐν ψυχῇ: in Galen, and Philo de Mund. Opif.
εἰ οὖν κ. τ. λ.] If then the LIGHT which is in thee is darkness, how dark must the DARKNESS be! i.e. ‘if the conscience, the eye and light of the soul, be darkened, in how much grosser darkness will all the passions and faculties be, which are of themselves naturally dark!’ The opposition is between τὸ φῶς and τὸ σκότος. This interpretation is borne out by the Vulgate: ‘Ipsæ tenebræ quantæ erunt!’ by Jerome: ‘Si sensus, qui lumen est, animæ vitio caligatur, ipsa putas caligo quantis tenebris obvolvetur!’ and by Chrysostom: ὅταν γὰρ ὁ κυβερνήτης ὑποβρόχιος γένηται, καὶ ὁ λύχνος σβεσθῇ καὶ ὁ ἡγεμὼν αἰχμάλωτος γένηται, ποία λοιπὸν ἔσται τοῖς ὑπηκόοις ἐλπίς: Hom. xx. 3, p. 264, and Euthymius: εἰ οὖν τὸ φῶς τὸ ἐν σοί, ὅ ἐστιν ὁ νοῦς, ὁ δωρηθεὶς εἰς τὸ φωτίζειν καὶ ὁδηγεῖν τὴν ψυχήν, σκότος ἐστί, τουτέστιν ἐσκότισται, λοιπὸν τὸ σκότος, τὸ ἀπὸ τῶν παθῶν, πόσον ἔσται, εἰς τὸ σκοτίζειν τὴν ψυχήν, σκοτισθέντος τοῦ ἀνατέλλοντος αὐτῇ φωτός. Augustine (de Serm. Dom. ii. c. 13 (46), vol. iii.) renders it similarly, but understands σκότος to refer to a different thing: ‘Si ipsa cordis intentio, qua facis quod facis, quæ tibi nota est, sordidatur appetitu rerum terrenarum … atque cæcatur: quanto magis ipsum factum, cujus incertus est exitus, sordidum et tenebrosum est!’ So too the Sy(82). æt(83). versions; and Erasm.: “Si ratio excæcata id judicat imprimis esse expetendum, quod vel contemnendum, vel neglectui habendum, in quas tenebras totum hominem rapiet ambitio reliquæque animi perturbationes, quæ suapte natura caliginem habent!”—Bucer, Luther. Stier expands this well, Reden Jesu, i. 208, edn. 2, “As the body, of itself a dark mass, has its light from the eye, so we have here compared to it the sensuous, bestial life ( ψυχικόν) of men, their appetites, desires, and aversions, which belong to the lower creature. This dark region—human nature under the gross dominion of the flesh—shall become spiritualized, enlightened, sanctified, by the spiritual light: but if this light be darkness, how great must then the darkness of the sensuous life be!” The usual modern interpretation makes τὸ σκότος πόσον a mere expression of the greatness of the darkness thereby occasioned, and thus loses the force of the sentence.
