John 8:12

Again therefore spake Jesus unto them, saying, I am the Light of the world. As we said that Jesus had made His Discourse in accordance with what was written of the feast, when at its last day He was standing crying, If any man thirst, let him come unto Me and drink, because the oracle of Moses had made mention of the brook: so now too does He make His explanation most seasonable, and due to the nature of things. For since He saw that the teachers were partners in folly with the multitudes and that the laughers were sick of the like with them they laughed at, drenched (so to speak) all of them in one night of unlearning and seeking to get hold of His Mystery yet finding nought at all, He brings forward the reason of tho want of understanding that is in them, crying, I am the Light of the world. Ye (He says) going through the whole holy Scripture and thinking to test the things spoken of Me through the Prophets, are far astray of the way of Life. And no marvel: for He is not in you Who revealeth mysteries and illumineth the whole world, and like a sun shineth into the hearts of them that receive Him. And needs must he who has not within him the Divine and spiritual Light surely walk in darkness and stumble on many absurdities therefrom. But that the Only-Begotten is by Nature Light, as beaming forth from God the Father Who is by Nature Light, we have shown at great length in the first book, on the words, He was the Very Light. But we must note again that He says that He is the Light not specially or solely of them of Israel, but of all the world. […]

He that followeth Me shall not walk in darkness, but shall have the light of life. He is again persuading them on all sides to aim at hunting after what is profitable, and to desire rather to be led by His appointments, than to choose to follow their own unlearning and bereave themselves of everlasting life. He shows how great shall be the profit to those who are obedient to Him, seeing He is by Nature Good and willeth all men to be saved and to come unto the knowledge of the truth. But since He knew as God that they would gainsay, He fashions His speech after an elder image of things and from what had befallen their ancestors He declares plainly that the desire to follow Him will be to their great profit. It was written then of them of Israel, that in the daytime also He led them with a cloud and all the night with a light of fire. For when they were crossing the wide desert, hasting unto the Land of promise, a cloud was suspended over them like a roof in the day driving off the sun's flame, by Divine Counsel that is: by night a pillar of fire contending with the darkness and marking out to the travellers their un-erring road did lead them. For just as they who at that time followed the guiding and conducting fire, escaped straying, and were borne straight forward along their right and holy ground, recking nought of night or darkness: so he that followeth Me, i. e., who goeth in the track of My teachings, shall in no wise be in the dark, but shall gain the light of life, that is, the revelation of My mysteries able to lead him by the hand unto everlasting life. […]

To neglect these things any further, and to persevere in the former error, what is it else than to fall under the Lord's rebuke, who in the l psalm reproveth, and says, "What hast thou to do to declare my statutes, or that thou shouldest take my covenant into thy mouth, seeing thou hatest instruction and castest my words behind thee? When thou sawest a thief, thou consentedst with him, and hast been partaker with adulterers." For to declare the righteousness and the covenant of the Lord, and not to do the same that the Lord did, what else is it than to cast away His words and to despise the Lord's instruction, to commit not earthly, but spiritual thefts and adulteries? While any one is stealing from evangelical truth the words and doings of our Lord, he is corrupting and adulterating the divine precepts, as it is written in Jeremiah. He says, "What is the chaff to the wheat? Therefore, behold, I am against the prophets, saith the Lord, who steal my words every one from his neighbour, and cause my people to err by their lies and by their lightness." Also in the same prophet, in another place, He says, "She committed adultery with stocks and stones, and yet for all this she turned not unto me." That this theft and adultery may not fall unto us also, we ought to be anxiously careful, and fearfully and religiously to watch. For if we are priests of God and of Christ, I do not know any one whom we ought rather to follow than God and Christ, since He Himself emphatically says in the Gospel, "I am the light of the world; he that followeth me shall not walk in darkness, but shall have the light of life." Lest therefore we should walk in darkness, we ought to follow Christ, and to observe his precepts, because He Himself told His apostles in another place, as He sent them forth, "All power is given unto me in heaven and earth. […]

Why do you rush into the darkness of jealousy? why do you enfold yourself in the cloud of malice? why do you quench all the light of peace and charity in the blindness of envy? why do you return to the devil, whom you had renounced? why do you stand like Cain? For that he who is jealous of his brother, and has him in hatred, is bound by the guilt of homicide, the Apostle John declares in his epistle, saying, "Whosoever hateth his brother is a murderer; and ye know that no murderer hath life abiding in him." And again: "He that saith he is in the light, and hateth his brother, is in darkness even until now, and walketh in darkness, and knoweth not whither he goeth, because that darkness hath blinded his eyes." Whosoever hates, says he, his brother, walketh in darkness, and knoweth not whither he goeth. For he goeth unconsciously to Gehenna, in ignorance and blindness; he is hurrying into punishment, departing, that is, from the light of Christ, who warns and says, "I am the light of the world. He that followeth me shall not walk in darkness, but shall have the light of life." But he follows Christ who stands in His precepts, who walks in the way of His teaching, who follows His footsteps and His ways, who imitates that which Christ both did and taught; in accordance with what Peter also exhorts and warns, saying, "Christ suffered for us, leaving you an example that ye should follow His steps."

That Christ our God should come, the En-lightener and Saviour of the human race. In Isaiah: "Be comforted, ye weakened hands; and ye weak knees, be strengthened. Ye who are of a timorous heart, fear not. Our God will recompense judgment, He Himself will come, and will save us. Then shall be opened the eves of the blind, and the ears of the deaf shall hear. Then the lame man shall leap as a stag, and the tongue of the dumb shall be intelligible; because in the wilderness the water is broken forth, and the stream in the thirsty land." Also in that place: "Not an elder nor an angel, but the Lord Himself shall deliver them; because He shall love them, and shall spare them, and He Himself shall redeem them. Also in the same place: "I the Lord God have called Thee in righteousness, that I may hold Thine hand, and I will comfort Thee; and I have given Thee for a covenant of my people, for a light of the nations; to open the eyes of the blind, to bring forth them that are bound from chains, and those who sit in darkness from the prison-house. I am the Lord God, that is my name. I will not: give any glory to another, nor my powers to given images." Also in the twenty-fourth Psalm: "Show me Thy ways, Lord, and teach me Thy paths, and lead me unto Thy truth, and teach me; for Thou art the God of my salvation." Whence, in the Gospel according to John, the Lord says: "I am the light of the world. He that will follow me shall not walk in darkness, but shall have the light of life." Moreover, in that according to Matthew, the angel Gabriel says to Joseph: "Joseph, thou son of David, fear not to take unto thee Mary thy wife. For that which shall be born to her is of the Holy Ghost. […]

What then did Christ? Since they were continually dwelling upon Galilee and "The Prophet," to free all men from this erroneous suspicion, and to show that He was not one of the prophets, but the Master of the world, He said, "I am the light of the world." Not "of Galilee," not of Palestine, nor of Judaea.

A great thing to say, great of a truth, but it did not greatly amaze them, because He did not now make Himself equal to the Father, nor assert that He was His Son, nor that He was God, but for a while calleth Himself "a light." They indeed desired to disprove this also, and yet this was a much greater thing than to say, "He that followeth Me, shall not walk in darkness." Using the words "light" and "darkness" in a spiritual sense, and meaning thereby "abideth not in error."

In this place He draweth on Nicodemus, and bringeth him in as having spoken very boldly, and praiseth the servants who had also done so. For to "cry aloud," is the act of one desirous to cause that they also should hear. At the same time He hinteth at these who were secretly contriving treacheries, being both in darkness and error, but that they should not prevail over the light. And He remindeth Nicodemus of the words which He had uttered before, "Every one that doeth evil hateth the light, neither cometh to the light, lest his deeds should be reproved." (c. iii. 20.) For since they had asserted that none of the rulers had believed on Him, therefore He saith, that "he that doeth evil cometh not to the light," to show that their not having come proceedeth not from the weakness of the light, but from their own perverse will.

For no one was able, either in heaven or in earth, or under the earth, to open the book of the Father, or to behold Him, with the exception of the Lamb who was slain, and who redeemed us with His own blood, receiving power over all things from the same God who made all things by the Word, and adorned them by [His] Wisdom, when "the Word was made flesh;" that even as the Word of God had the sovereignty in the heavens, so also might He have the sovereignty in earth, inasmuch as [He was] a righteous man, "who did no sin, neither was there found guile in His mouth;" and that He might have the pre-eminence over those things which are under the earth, He Himself being made "the first-begotten of the dead;" and that all things, as I have already said, might behold their King; and that the paternal light might meet with and rest upon the flesh of our Lord, and come to us from His resplendent flesh, and that thus man might attain to immortality, having been invested with the paternal light.

[Christ] is the brightness of souls, the one who drives away the darkness of ignorance, and the one who reveals mysteries that can be perceived only by the pure.

You may bring these words against Nestorius: for our Lord does not say, In Me is the light of the world, but, I am the Light of the world: He who appeared man, was both the Son of God, and the Light of the world; not, as Nestorius fondly holds, the Son of God dwelling in a mere man.

Since they constantly reproached Christ with Galilee and took Him to be one of the prophets, He shows them that He is not one of the prophets. "I," He says, "am the Light of the world, light in the proper sense, not a prophetic light, …

"Again therefore Jesus spoke to them: I am the light of the world." Having confuted the perversity of the Jews, in this second part the Lord manifests the dignity and nobility of his doctrine. Now the nobility of his doctrine consists in this, that it …

Having absolved the woman from her sin, lest some should doubt, seeing that He was really man, His power to forgive sins, He deigns to give further disclosure of His divine nature; Then spake Jesus again unto them, saying, I am the Light of the world.

Where it is to be observed, He does not say, I am the light of Angels, or of heaven, but the Light of the world, i. e. of mankind who live in darkness, as we read, To give light to them that sit in darkness, and in the shadow of death. (Luke 1:79)

The Evangelist has presented Christ as teaching; now he shows, first, the power which this teaching has to give light, and secondly, what Christ himself said about it (v 13). With respect to the first he does three things: first, he states Christ's prerogative concerning …

The visible light of the world is the sun, and Christ is the Sun of righteousness. One sun enlightens the whole world, so does one Christ, and there needs no more. Christ in calling himself the light expresses, (1.) What he is in himself--most excellent and glorious.

He that followeth me shall in nowise walk in darkness - In ignorance, wickedness, misery: but shall have the light of life -He that closely, humbly, steadily follows me, shall have the Divine light continually shining upon him, diffusing over his soul knowledge, holiness, joy, till he is guided by it to life everlasting.

Then spake Jesus again unto them,....

OUR Lord did not speak in this way at the beginning of His ministry. He did not thus bear witness to Himself, saying, "I am the light of the world." But it was befitting on this occasion, when the people before Him had already received sufficient evidence from other quarters. John the Baptist, whom all men counted for a Prophet, had testified that Christ was the true Light of God which lights every man that comes into the world.

In "the treasury" where it was spoken (see on Joh 8:20) stood two colossal golden lamp-stands, on which hung a multitude of lamps, lighted after the evening sacrifice (probably every evening during the feast of tabernacles), diffusing their brilliancy, it is said, over all the city.

The conversation between our Lord and the Jews, which begins with these verses, is full of difficulties. The connection between one part and another, and the precise meaning of some of the expressions which fell from our Lord's lips, are "things hard to be understood." In passages like this it is true wisdom to acknowledge the great imperfection of our spiritual vision, and to be thankful if we can glean a few handfuls of truth. Let us notice, for one thing, in these verses, what the Lord Jesus says of Himself. He proclaims, "I am the light of the world."

Let us notice, for one thing, in these verses, what the Lord Jesus says of Himself. He proclaims, "I am the light of the world." These words imply that the world needs light, and is naturally in a dark condition. It is so in a moral and spiritual point of view—and it has been so for nearly 6,000 years. In ancient Egypt, Greece, and Rome, in modern England, France, and Germany, the same report is true. The vast majority of men neither see nor understand the value of their souls, the true nature of God, nor the reality of a world to come! Notwithstanding all the discoveries of art and science, "darkness still covers the earth, and gross darkness the people." (Isaiah. 60:2.) For this state of things, the Lord Jesus Christ declares Himself to be the only remedy. He has risen, like the sun, to diffuse light, and life, and peace, and salvation, in the midst of a dark world. He invites all who want spiritual help and guidance to turn to Him, and take Him for their leader. What the sun is to the whole solar system—the center of light, and heat, and life, and fertility—that He has come into the world to be to sinners. Let this saying sink down into our hearts. It is weighty and full of meaning. False lights on every side invite man's attention in the present day. Reason, philosophy, earnestness, liberalism, conscience, and the voice of the Church, are all, in their various ways, crying loudly that they have got "the light" to show us.

OUR Lord did not speak in this way at the beginning of His ministry. He did not thus bear witness to Himself, saying, "I am the light of the world." But it was befitting on this occasion, when the people before Him had already received sufficient evidence from other quarters. John the Baptist, whom all men counted for a Prophet, had testified that Christ was the true Light of God which lights every man that comes into the world. The witness of John they rejected— startling, if not conclusive, as it must have been—considering the esteem in which his oracular voice was held. Moreover, Jesus, Himself, had worked conviction in their hearts by His teaching. Had they not listened to His famous Sermon on the Mount? Could they not feel the authority with which He spoke? Did they not confess to the impressions He produced on them? The weight and the wisdom of His discourse manifested a power that could melt their thoughts into the very mold of His ministry. Nor was it merely His teaching, transparent though that was, but the signs He showed and the miracles He worked with the majesty of His voice and the virtue of His touch proclaimed that He was the Light of the world! Thus the infirmities of the creature called forth His Divine compassion. With radiant eyes of pity He looked on the wretched and gave them quick relief—He shone on their sadness like the Sun of Righteousness, with healing in His beams. They hailed His visit in every town and village as the Healer of all who were diseased. Might not the quick sense of every unprejudiced spectator detect in Him the Messiah and welcome His advent to the worlds? At length, as though aggrieved by their unbelief, He speaks loudly and proclaims plainly, "I am the light of the world." Such high ground does He take before His adversaries. Well might He say it to their teeth.

I am the light of the world - See the notes at Joh 1:4, Joh 1:9.
