And the light shineth in darkness. It might be objected, that the passages of Scripture in which men are called blind are so numerous and that the blindness for which they are condemned is but too well known. For in all their reasoning faculties they miserably fail. How comes it that there are so many labyrinths of errors in the world, but because men, by their own guidance, are led only to vanity and lies? But if no light appears in men, that testimony of the divinity of Christ, which the Evangelist lately mentioned, is destroyed; for that is the third step, as I have said, that in the life of men there is something more excellent than motion and breathing. The Evangelist anticipates this question, and first of all lays down this caution, that the light which was originally bestowed on men must not be estimated by their present condition; because in this corrupted and degenerate nature light has been turned into darkness. And yet he affirms that the light of understanding is not wholly extinguished; for, amidst the thick darkness of the human mind, some remaining sparks of the brightness still shine. My readers now understand that this sentence contains two clauses; for he says that men are now widely distant from that perfectly holy nature with which they were originally endued; because their understanding, which ought to have shed light in every direction, has been plunged in darkness, and is wretchedly blinded; and that thus the glory of Christ may be said to be darkened amidst this corruption of nature. But, on the other hand, the Evangelist maintains that, in the midst of the darkness:, there are still some remains of light, which show in some degree the divine power of Christ. The Evangelist admits, therefore, that the mind of man is blinded; so that it may justly be pronounced to be covered with darkness. For he might have used a milder term, and might have said that the light is dark or cloudy; but he chose to state more distinctly how wretched our condition has become since the fall of the first man. The statement that the light shineth in darkness is not at all intended for the commendation of depraved nature, but rather for taking away every excuse for ignorance. And the darkness did not comprehend it. Although by that small measure of light which still remains in us, the Son of God has always invited men to himself, yet the Evangelist says that this was attended by no advantage, because seeing, they did not see, (Matthew 13:13.) For since man lost the favor of God, his mind is so completely overwhelmed by the thralldom of ignorance, that any portion of light which remains in it is quenched and useless. This is daily proved by experience; for all who are not regenerated by the Spirit of God possess some reason, and this is an undeniable proof that man was made not only to breathe, but to have understanding. But by that guidance of their reason they do not come to God, and do not even approach to him; so that all their understanding is nothing else than mere vanity. Hence it follows that there is no hope of the salvation of men, unless God grant new aid; for though the Son of God sheds his light upon them, they are so dull that they do not comprehend whence that light proceeds, but are carried away by foolish and wicked imaginations to absolute madness. The light which still dwells in corrupt nature consists chiefly of two parts; for, first, all men naturally possess some seed of religion; and, secondly, the distinction between good and evil is engraven on their consciences. But what are the fruits that ultimately spring from it, except that religion degenerates into a thousand monsters of superstition, and conscience perverts every decision, so as to confound vice with virtue? In short, natural reason never will direct men to Christ; and as to their being endued with prudence for regulating their lives, or born to cultivate the liberal arts and sciences, all this passes away without yielding any advantage. It ought to be understood that the Evangelist speaks of natural gifts only, and does not as yet say any thing about the grace of regeneration. For there are two distinct powers which belong to the Son of God: the first, which is manifested in the structure of the world and the order of nature; and the second, by which he renews and restores fallen nature. As he is the eternal Speech of God, by him the world was made; by his power all things continue to possess the life which they once received; man especially was endued with an extraordinary gift of understanding; and though by his revolt he lost the light of understanding, yet he still sees and understands, so that what he naturally possesses from the grace of the Son of God is not entirely destroyed. But since by his stupidity and perverseness he darkens the light which still dwells in him, it remains that a new office be undertaken by the Son of God, the office of Mediator, to renew, by the Spirit of regeneration, man who had been ruined. Those persons, therefore, reason absurdly and inconclusively, who refer this light, which the Evangelist mentions, to the gospel and the doctrine of salvation.

The light shineth in darkness - Darkness, in the Bible, commonly denotes ignorance, guilt, or misery. See Isaiah 9:1-2; Matthew 4:16; Acts 26:18; Ephesians 5:8, Ephesians 5:11; Romans 13:12. It refers here to a wicked and ignorant people. When it is said that "the light shineth in darkness," it is meant that the Lord Jesus came to teach an ignorant, benighted, and wicked world. This has always been the case. It was so when he sent his prophets; so during his own ministry; and so in every age since. His efforts to enlighten and save men have been like light struggling to penetrate a thick, dense cloud; and though a few rays may pierce the gloom, yet the great mass is still an impenetrable shade.
Comprehended it not - This word means "admitted" it not, or "received" it not. The word "comprehend," with us, means to "understand." This is not the meaning of the original. The darkness did not "receive" or "admit" the rays of light; the shades were so thick that the light could not penetrate them; or, to drop the figure, men were so ignorant, so guilty, so debased, that they did not appreciate the value of his instructions; they despised and rejected him. And so it is still. The great mass of men, sunk in sin, will not receive his teachings, and be enlightened and saved by him. Sin always blinds the mind to the beauty and excellency of the character of the Lord Jesus. It indisposes the mind to receive his instructions, just as "darkness" has no affinity for "light;" and if the one exists, the other must be displaced.

And the light shineth in darkness - By darkness here may be understood:
1. The heathen world, Ephesians 5:8.
2. The Jewish people.
3. The fallen spirit of man.
Comprehended it not - Αυτο ου κατελαβεν, Prevented it not - hindered it not, says Mr. Wakefield, who adds the following judicious note: - "Even in the midst of that darkness of ignorance and idolatry which overspread the world, this light of Divine wisdom was not totally eclipsed: the Jewish nation was a lamp perpetually shining to the surrounding nations; and many bright luminaries, among the heathen, were never wanting in just and worthy notions of the attributes and providence of God's wisdom; which enabled them to shine in some degree, though but as lights in a dark place, 2-Peter 1:19. Compare Acts 14:17; Acts 17:28, Acts 17:29."

(3) And the light shineth in darkness; and the darkness (m) comprehended it not.
(3) The light of men is turned into darkness, but yet there is enough clearness so that they are without excuse.
(m) They could not perceive nor reach it to receive any light from it, no, they did not so much as acknowledge him.

And the light shineth in darkness,.... Which, through sin, came upon the minds of men; who are naturally in the dark about the nature and perfections of God; about sin, and the consequences of it; about Christ, and salvation by him; about the Spirit of God, and his work upon the soul; and about the Scriptures of truth, and the doctrines of the Gospel. Man was created a knowing creature, but, not content with his knowledge, sins, and is banished from the presence of God, the fountain of light; which brought a darkness on him, and his posterity, and which is increased in them by personal iniquity, and in which Satan, the god of this world, has an hand; and sometimes they are left to judicial blindness, and which issues in worse darkness, if grace prevents not: now amidst this darkness there were some remains of the light of nature: with respect to the being of God, which shines in the works of creation and providence and to the worship of God, though very dimly; and to the knowledge of moral good and evil:
and the darkness comprehended it not; or "perceived it not"; as the Syriac version renders it. By the light of nature, and the remains of it, men could not come to any clear and distinct knowledge of the above things; and much less to any knowledge of the true way of salvation: unless, rather by the light should be meant, the light of the Messiah, or of the Gospel shining in the figures, types, and shadows of the law, and in the prophecies and promises of the Old Testament: and yet, such was the darkness upon the minds of men, that they could not very distinctly apprehend it, and much less fully comprehend it, so that there was need of a fresh and fuller revelation; an account of which follows;

shineth in darkness, &c.--in this dark, fallen world, or in mankind "sitting in darkness and the shadow of death," with no ability to find the way either of truth or of holiness. In this thick darkness, and consequent intellectual and moral obliquity, "the light of the Word" shineth--by all the rays whether of natural or revealed teaching which men (apart from the Incarnation of the Word) are favored with.
the darkness comprehended it not--did not take it in, a brief summary of the effect of all the strivings of this unincarnate Word throughout this wide world from the beginning, and a hint of the necessity of His putting on flesh, if any recovery of men was to be effected (1-Corinthians 1:21).

And the light shineth in darkness - Shines even on fallen man; but the darkness - Dark, sinful man, perceiveth it not.
