Mateus 6:22-23

DISCOURSE: 1322
THE SINGLE EYE

Mateus 6:22. 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. If therefore the light that is in thee be darkness, how great is that darkness!

REASON is certainly the richest endowment of the human mind. When regulated by the word and Spirit of God, it will direct our paths, and enable us to guard against every dangerous or important error; but it is capable of being so warped by specious reasonings, and selfish considerations, as to become an engine of Satan, and an instrument of our more aggravated ruin: there is nothing, however unreasonable, which a perverse spirit will not do; nor any thing, however criminal, which it will not justify. Hence our blessed Lord, in the passage before us, inculcated on his followers the necessity of having “a single eye,” and of acting on all occasions with a well-informed and upright intention.
Let us consider,

I. The instruction here given us—

There is “a light within us,” which is to the soul what the natural eye is to the body; and, if preserved in healthful exercise, will serve, in most instances, to direct our steps: but if it be vitiated and obscured by the film of vile affections, it will itself become as darkness.
But it may be asked, Can reason or conscience ever be so perverted as to become darkness? I answer, Yes: and this is actually the case,

1. When, though it does shine, we will not follow its direction—

[The eye, supposing it to be free from any defects, is capable of directing all the motions of the body. So reason or conscience, if freed from all undue bias, will serve in a great measure to regulate the active powers of the soul [Note: Provérbios 20:27.]. But as a person who should keep his eyes shut in order that he might not behold the light, would be in the same predicament with one who was really blind; so the person, who either will not bring his reason and conscience to the light of God’s word, or obstinately determines to persist in the paths of error, is, in effect at least, as much in darkness, as if he did not possess any such faculties—]

2. When it is obscured by any defect in the organs of vision—

[As vicious humours will destroy the sight of our bodily eyes, so will sinful affections impair the powers of the mind. Prejudice, passion, or interest, will often blind us to such a degree, that we cannot discern the things that are most obvious to others. We all are sensible of this weakness in others; and it would be well if we were more on our guard respecting it in ourselves. Not to mention the innumerable instances which manifest themselves in our conduct towards each other, how universally are men blinded in their conduct towards God! While Christianity in general, is allowed to be both good and necessary, there is scarcely any regard paid to its particular, and most distinguishing tenets. Its fundamental doctrines, such as original sin, justification by faith, regeneration by the Holy Spirit, are discarded as erroneous; and its most essential precepts of holiness and self-denial are ridiculed as preciseness and enthusiasm. Where the jaundiced eye receives such an impression respecting the most important truths, its light must be considered as no better than darkness—]

3. When under a professed regard to it, we do what is in itself evil—

[It is no uncommon thing to put “evil for good, and darkness for light,” and to engage earnestly in some evil conduct under the idea that we are doing what is right [Note: Isaías 5:20.]. Our Lord has taught us to expect that men would persecute and even “kill his faithful followers, and imagine all the time that they were doing God service.” And Paul, in the midst of all his boasted morality, persecuted the Christians even unto death, and persuaded himself that “he ought to do” so [Note: João 16:2.Atos 26:9.]. A similar conduct yet obtains in the world. There are thousands who yet think it their duty to oppose the progress of the Gospel, and to repress by every means in their power its influence over their friends and relatives. The light of such persons surely is, not only dark, but darkness itself—]

It appears then, that our Lord cautions us not to neglect or violate the dictates of our conscience. And to impress this lesson more deeply on our minds, I will mark,

II.

The vast importance of it to every child of man—

The Jews had manifested a most astonishing per- verseness in resisting all the evidences of our Lord’s mission; and he well knew how fatal it would prove to them, if they should persist in it any longer. Hence he gave them this solemn caution, which may, for similar reasons, be given also unto us,

1. The evil against which we are guarded, is a common evil—

[Though there is much ignorance in the world, yet there are few, if any, whose practice does not fall very far short of what they know to be their duty. There certainly are different degrees of light in the minds of unconverted men; but all in some measure “resist the truth,” and “imprison it in unrighteousness [Note: Romanos 1:18. κατεχόντων. A heathen felt this: “Video meliora, proboque; deteriora sequor.”].” When therefore this evil is so general, should we not be on our guard against it? When all of us see how much it prevails in others, should we not suspect its influence over ourselves? Let every one tremble for his own house, when he sees it standing in the midst of a general conflagration—]

2. It is an evil to which we are prone—

[The heart is justly said to be “deceitful above all things, and desperately wicked.” It is ready and ingenious in colouring over its own devices, and in justifying whatever tends to its own satisfaction. The world also presents to us ten thousand pleas that serve to confirm our delusions. And Satan, who beguiled our first parents in Paradise, doubtless lends his aid to lead us astray, and to keep us ignorant of our real state. Who is there amongst us that has not experienced this proneness to self-deception? The very Apostles on some occasions “knew not what spirit they were of.” And who has not repeatedly found, that the things, which seemed right in his eyes at one time, have, in an hour of sober reflection, appeared to have been the extremest folly? Surely then we never can be too watchful against the treachery of our own hearts—]

3. It is an evil that greatly aggravates our guilt—

[God has given us a conscience capable of “accusing or excusing” us according to the true tenour of our actions [Note: Romanos 2:15.]. Now if we either warp it by vile affections, or silence it by continued opposition to its dictates, our sin is aggravated a hundred-fold. This is repeatedly declared both by Christ and his Apostles [Note: Tiago 4:17; João 15:22; João 9:41; João 3:19.]. And can we suppose that our punishment also will not be proportionably enhanced? Will not “the servant who knew his Lord’s will and did it not, be beaten with more stripes than he who transgressed through ignorance?” Will not those, who improved a less degree of light, “rise up in judgment against” those who enjoyed more ample means of instruction, and yet neglected to improve them? No doubt, it were “better never to have known the will of God at all, than, having known it,” to live in an allowed opposition to it—]

4. It is an evil that involves us in the greatest danger—

[If we will not receive the truth in the love of it, we have reason to fear that God will give us up to our own delusions, that we may believe a lie, and receive the condemnation due to our perverseness [Note: 2 Tessalonicenses 2:11.]. He sometimes suffers the light itself to have no other effect than to blind our eyes [Note: Isaías 6:9.]. And what a tremendous judgment would that be! We should only wander further and further from God, till we had “filled up the measure of our iniquities,” and be thus “treasuring up for ourselves wrath against the day of wrath.” Should we ever be left to this state, “better were it for us that we had never been born.”]

Having thus explained the reasons of this caution, we shall conclude with a few words of advice—
1.

Get your conscience truly enlightened—

[It needs the illumination of God’s word and Spirit. Without that it will be but a blind guide at best. God however has promised, for the comfort of those who seek him, that “The meek he will guide in judgment, the meek he will teach his way.”]

2. Regard the dictates of conscience in little things;—

[Conscience must maintain an uncontrolled, unlimited sway. You must “exercise yourself daily to keep it void of offence towards God and man.” If you violate its dictates in small things, you will soon cease to reverence it in greater matters. But listen to its voice on all occasions, and it will never suffer you to err materially. There shall always be a voice behind you, saying, “This is the way, walk ye in it [Note: Isaías 30:21.].”]

3. Guard against worldly and carnal lusts—

[It is astonishing to what a degree even the most sensible men, as David and Solomon, may be blinded by “foolish and hurtful lusts.” The love of money, of pleasure, or of honour, alas! how will they warp the judgment, how will they divert us from the path of duty! Love not the world if you have any wish to possess the love of God. The two attachments are inconsistent and incompatible with each other [Note: 1 João 2:15.]

4. Set the Lord Jesus ever before you—

[He is the light of the world; and if you will follow him, you shall never walk in darkness [Note: João 8:12.]. If you can find what Christ would have done in your situation, do that resolutely and universally.]
