(8) He was not that Light, but was sent.--It is necessary to repeat the statement of John's position and work in an emphatic form. Now first for 400 years a great teacher had appeared in Israel. The events of his birth and life had excited the attention of the masses; his bold message, like the cry of another Elias, found its way in burning words to the slumbering hearts of men; and even from the least likely classes, from Pharisee and Sadducee, from publican and soldier, there came the heart's question, "What shall we do?" The extent of the religious revival does not impress us, because it passed into the greater which followed, but the statement of a publican living at the time is that "Jerusalem, and all Judaea, and all the region round about Jordan, went out to Him, and were baptized of Him in Jordan, confessing their sins" (Matthew 3:5-6). But what was this power in their midst? Who could be the person uttering these more than human words? A comparison of John 1:19-20 in this chapter with Luke 3:15 shows a widespread opinion that he was at least possibly the Messiah. He himself with true greatness recognised the greater, but as in many a like case in after days, the followers had not all the leader's nobility of soul. We shall meet signs of this in John 3:26; John 4:1. We find traces of it in Matthew 9:14, &c. (see Note at this place), and even in Ephesus, as late as St. Paul's third missionary journey, we find "certain disciples" knowing nothing more than "John's baptism" (Acts 19:1-6). It was at Ephesus that this Gospel was written and the existence of a body of such "disciples" may have led to the full statement in this verse made by one who had himself been among the Baptist's earliest followers.

It was otherwise with the disciple who wrote these words. He is content to claim for his master as for himself the noblest human work, "to bear witness of that Light." No one may add to it; all may, in word and life, bear witness to it. Every discovery in science and advance in truth is a removal of some cloud which hides it from men; every noble character is bearing it about; every conquest of sin is extending it. It has been stored in mines of deepest thought in all ages. The heedless pass over the surface unconscious of it. The world's benefactors are they who bring it forth to men as the light and warmth of the rays of the Sun of Righteousness. (Comp. John 5:35, and Note there.)

Verse 8. - A solemn warning is given, which forever discriminates the ministry of man from the eternal ministry of the Logos. He (John, and with him all the prophetic, Levitical, ascetic teachers in all ages) was not the Light, but [he was or came] that he might bear witness of the Light. The ἵνα depends upon some unexpressed verbal thought; for even in the passages where it stands alone (John 9:3; John 13:18; John 14:31; John 15:25) the reference is not obscure to some pre-existing or involved verb. The distinction here drawn between John and the Light is thought by some expositors to point to the condition of the Ephesian Church, in the neighbourhood of which there still lingered some who placed John in even a higher position than that accorded to Jesus (Acts 19:3, 4); but the teaching of the evangelist is far more comprehensive than this. The Light of men has higher source and wider range of operation than that of any prophetic man. All that he, that any seer whatsoever can do, is to bear witness to it. The prophets, from Moses to John, derived all their power, their sanction, and the corroboration of their message, from the Logos light shining through conscience and blazing through providential events and burning up the stubble of human action with unquenchable fire. The prophets are not the light of God; they are sent to bear witness to it.

1:6-14 John the Baptist came to bear witness concerning Jesus. Nothing more fully shows the darkness of men's minds, than that when the Light had appeared, there needed a witness to call attention to it. Christ was the true Light; that great Light which deserves to be called so. By his Spirit and grace he enlightens all that are enlightened to salvation; and those that are not enlightened by him, perish in darkness. Christ was in the world when he took our nature upon him, and dwelt among us. The Son of the Highest was here in this lower world. He was in the world, but not of it. He came to save a lost world, because it was a world of his own making. Yet the world knew him not. When he comes as a Judge, the world shall know him. Many say that they are Christ's own, yet do not receive him, because they will not part with their sins, nor have him to reign over them. All the children of God are born again. This new birth is through the word of God as the means, 1Pe 1:23, and by the Spirit of God as the Author. By his Divine presence Christ always was in the world. But now that the fulness of time was come, he was, after another manner, God manifested in the flesh. But observe the beams of his Divine glory, which darted through this veil of flesh. Men discover their weaknesses to those most familiar with them, but it was not so with Christ; those most intimate with him saw most of his glory. Although he was in the form of a servant, as to outward circumstances, yet, in respect of graces, his form was like the Son of God His Divine glory appeared in the holiness of his doctrine, and in his miracles. He was full of grace, fully acceptable to his Father, therefore qualified to plead for us; and full of truth, fully aware of the things he was to reveal.He was not that light,.... He was a light; he was the forerunner of the sun of righteousness, the "phosphorus" of the Gospel day; he had great light in him; he knew that the Messiah was ready to come, and declared it; and upon his baptism he knew him personally, and signified him to others: he had great light into the person and work of Christ; and into the way of salvation by him, and remission of sins through him; into the doctrines of faith in Christ, and of evangelical repentance towards God; and into the abolition of the legal Mosaic and Jewish dispensation; and was an instrument of giving light to others; yea, he was a burning and shining light, in whose light the Jews rejoiced, at least for a season: but then he was not that light, the word and wisdom of God; that uncreated light that dwelt with him from all eternity; nor that which was the light of men, from the creation; nor that light, which was of old promised to the saints and patriarchs of the Old Testament, and shone in the ordinances and predictions of that state; nor that fountain and giver of light, of every sort, to men; not that light in which is no darkness, and always shines; not that true light, or sun of righteousness, the Messiah, or that lightens every man that comes into the world:

but was sent to bear witness of that light; which is repeated, to distinguish him from that light; to show what he was sent for, and that he acted according to his mission; and to express the honourableness to his work.
