Matthew 6:23

Otherwise; He now teaches the benefit of almsgiving. He who places his treasure on earth has nothing to look for in Heaven; for why should he look up to Heaven where he has nothing laid up for himself? Thus he doubly sins; first, because he gathers together things evil; secondly, because he has his heart in earth; and so on the contrary he does right in a twofold manner who lays up his treasure in Heaven. It seems that He is not here speaking of the bodily eye, or of the outward body that is seen, or He would have said, If thine eye be sound, or weak; but He says, single, and, evil. But if one have a benign yet diseased eye, is his body therefore in light? Or if an evil yet a sound, is his body therefore in darkness?

What He saith is like this: Bury not gold in the earth, nor do any other such thing, for thou dost but gather it for the moth, and the rust, and the thieves. And even if thou shouldest entirely escape these evils, yet the enslaving of thine heart, the nailing it to all that is below, thou wilt not escape: "For wheresoever thy treasure may be, there is thine heart also." As then, laying up stores in heaven, thou wilt reap not this fruit only, the attainment of the rewards for these things, but from this world thou already receivest thy recompence, in getting into harbor there, in setting thine affections on the things that are there, and caring for what is there (for where thou hast laid up thy treasures, it is most clear thou transferrest thy mind also); so if thou do this upon earth, thou wilt experience the contrary. But if the saying be obscure to thee, hear what comes next in order. "The light of the body is the eye; if therefore thine eye be single, thy whole body shall be full of light. But if thine eye be evil, thy whole body shall be full of darkness. But if the light that is in thee be darkness, how great is the darkness!" He leads His discourse to the things which are more within the reach of our senses. I mean, forasmuch as He had spoken of the mind as enslaved and brought into captivity, and there were not many who could easily discern this, He transfers the lesson to things outward, and lying before men's eyes, that by these the others also might reach their understanding. […]

And as they that are in darkness see nothing distinct, but if they look at a rope, they suppose it to be a serpent, if at mountains and ravines, they are dead with fear; so these also: what is not alarming to them that have sight, that they regard with suspicion. Thus among other things they tremble at poverty: or rather not at poverty only, but even at any trifling loss. Yea, and if they should lose some little matter, those who are in want of necessary food do not so grieve and bewail themselves as they. At least many of the rich have come even to the halter, not enduring such ill fortune: and to be insulted also, and to be despitefully used, seems to them so intolerable, that even because of this again many have actually torn themselves from this present life. For to everything wealth had made them soft, except to the waiting on it. Thus, when it commands them to do service unto itself, they venture on murders, and stripes, and revilings, and all shame. A thing which comes of the utmost wretchedness; to be of all men most effeminate, where one ought to practise self-command, but where more caution was required, in these cases again to become more shameless and obstinate. Since in fact the same kind of thing befalls them, as one would have to endure who had spent all his goods on unfit objects. For such an one, when the time of necessary expenditure comes on, having nothing to supply it, suffers incurable evils, forasmuch as all that he had hath been ill spent beforehand. And as they that are on the stage, skilled in those wicked arts, do in them go through many things strange and dangerous, but in other necessary and useful things none so ridiculous as they; even so is it with these men likewise. […]

Consequently, he adapts: If then the light that is in thee be darkness, namely, the light of reason, the darkness itself how great shall it be! Of this light, the Psalm says: "The light of your countenance is signed upon us" (Ps 4:6). He means …

(Mor. xxviii. 11.) Otherwise; if the light that is in thee, that is, if what we have begun to do well, we overcloud with evil purpose, when we do things which we know to be in themselves evil, how great is the darkness!

"The eye is the lamp of the body: if therefore thine eye be sound, thy whole body shall be full of light. But if thine eye be evil, thy whole body shall be full of darkness. If therefore the light that is in thee be …

But if thine eye be evil,....

There are three subjects brought before us in this part of our Lord’s sermon on the mount. These three are fasting, worldliness, and singleness of purpose in religion. Fasting, or occasional abstinence from food in order to bring the body into subjection to the spirit, is a practice frequently mentioned in the Bible, and generally in connection with prayer. David fasted when his child was sick; Daniel fasted when he sought special light from God; Paul and Barnabas fasted when they appointed elders; Esther fasted before going in to Ahasuerus.

But if thine eye be evil--distempered, or, as we should say, If we have got a bad eye. thy whole body shall be full of darkness--darkened. As a vitiated eye, or an eye that looks not straight and full at its object, sees nothing as it is, so a mind and heart divided between heaven and earth is all dark.

David fasted when his child was sick; Daniel fasted when he sought special light from God; Paul and Barnabas fasted when they appointed elders; Esther fasted before going in to Ahasuerus. It is a subject about which we find no direct command in the New Testament. It seems to be left to everyone’s discretion, whether he will fast or not. In this absence of direct command we may see great wisdom. Many a poor man never has enough to eat, and it would be an insult to tell him to fast: many sick people can hardly be kept well with the closest attention to diet, and could not fast without bringing on illness. It is a matter in which everyone must be persuaded in their own mind, and not rashly condemn others who do not agree with him. One thing only must never be forgotten: those who fast should do it quietly, secretly and without ostentation. Let them not “appear to men to fast.” Let them not fast to man, but to God. Worldliness is one of the greatest dangers that beset man’s soul. It is no wonder that we find our Lord speaking strongly about it: it is an insidious, specious, plausible enemy; it seems so innocent to pay close attention to our business! It seems so harmless to seek our happiness in this world, so long as we keep clear of open sins! Yet here is a rock on which many make shipwrecked to all eternity. They “lay up treasure on earth,” and forget to “lay up treasure in heaven.” May we all remember this! Where are our hearts? What do we love best?

THIS sentence has in it the nature of a Proverb. It is well worthy of frequent quotation, as it is applicable to such various circumstances. It is one of the most pithy, terse utterances of our Savior. So full of meaning is, it that it would be utterly impossible for us to draw out all its analogies. It is capable of adaptation to so many different things that the ablest commentators despair of being able to give you the whole of its fullness.

It is capable of adaptation to so many different things that the ablest commentators despair of being able to give you the whole of its fullness. But mark—very much of the meaning is to be discovered by the use—as the varieties of our personal experience furnish varieties of practical reflection. For example, we may interpret the passage of conscience as the eye of the soul—conscience must be clear and simple. If the conscience, which is the candle of the Lord, and which searches the secret parts of the belly, is not light but darkness, how great must be the darkness! If a man has not enough conscience to know darkness from light, and light from darkness, then he puts bitter for sweet, and sweet for bitter; if that only power, on which seems to tremble some rays of the ancient light of manhood, is darkened—if the lighthouse is quenched, if the windows are sealed up—how great, indeed, must be the darkness of man! We cannot wonder, when once a man has a depraved, and seared conscience, that he willingly runs into iniquity, commits sin with both hands, and goes from step to step till he obtains the highest seat in the scale of sin! The symbol of the eye here may also refer to the understanding, taken in a yet broader sense than as the conscience; for, I suppose, that conscience is, after all, but the understanding exercised about moral truth.

If ever a man on this earth lived to embody the tremendous text, "But if the \ light in your body be darkness, how great is the darkness," it was certainly he. \ Great men like Ariosto, Rabelais, and Shakspere fall in foul places, flounder …
