John 1:7

That all men might believe through him; i.e. by John the Baptist’s preaching, who was God’s instrument to induce them to believe in Jesus the Christ, or the Messias, their only Redeemer. (Witham)

2. We are here told what his office and business were (v. 7): The same came for a witness, an eye-witness, a leading witness. He came eis martyrian—for a testimony. The legal institutions had been long a testimony for God in the Jewish church. By them revealed religion was kept up; hence we read of the tabernacle of the testimony, the ark of the testimony, the law and the testimony: but now divine revelation is to be turned into another channel; now the testimony of Christ is the testimony of God, 1 Cor 1 6; 2 1. Among the Gentiles, God indeed had not left himself without witness (Acts 14 17), but the Redeemer had no testimonies borne him among them. There was a profound silence concerning him, till John Baptist came for a witness to him. Now observe, (1.) The matter of his testimony: He came to bear witness to the light. Light is a thing which witnesses for itself, and carries its own evidence along with it; but to those who shut their eyes against the light it is necessary there should be those that bear witness to it. Christ's light needs not man's testimony, but the world's darkness does. John was like the night watchman that goes round the town, proclaiming the approach of the morning light to those that have closed their eyes, and are not willing themselves to observe it; or like that watchman that was set to tell those who asked him what of the night that the morning comes, and, if you will enquire, enquire ye, Isa 21 11, 12. He was sent of God to tell the world that the long-looked-for Messiah was now come, who should be a light to enlighten the Gentiles and the glory of his people Israel; and to proclaim that dispensation at hand which would bring life and immortality to light. (2.) The design of his testimony: That all men through him might believe; not in him, but in Christ, whose way he was sent to prepare. He taught men to look through him, and pass through him, to Christ; through the doctrine of repentance for sin to that of faith in Christ. He prepared men for the reception and entertainment of Christ and his gospel, by awakening them to a sight and sense of sin; and that, their eyes being thereby opened, they might be ready to admit those beams of divine light which, in the person and doctrine of the Messiah, were now ready to shine in their faces. If they would but receive this witness of man, they would soon find that the witness of God was greater, 1 John 5 9. See ch. 10 41. Observe, it was designed that all men through him might believe, excluding none from the kind and beneficial influences of his ministry that did not exclude themselves, as multitudes did, who rejected the counsel of God against themselves, and so received the grace of God in vain.

We have here the turning over of two disciples from John to Jesus, and one of them fetching in a third, and these are the first-fruits of Christ's disciples; see how small the church was in its beginnings, and what the dawning of the day of its great things was.

not the Christ, not an angel, but a man; yet one, than whom (as our Saviour saith) there had not risen a greater amongst those that were born of women. He did not come of his own head, but was sent; for it was he of whom it was written, Mal 3:1, Behold, I will send my messenger before thy face, & c., Luk 7:27, he was not sent of men, but from God, foretold by the angel, as to his existence, name, work, and success, Luk 1:13-17. his name was John, named by the angel, Luk 1:13, before he was born; by his father and mother, Luk 1:60,63, when he was born. John signifieth grace; and doubtless the Baptist obtained that name, because he was to be the first and a famous preacher of the grace of the gospel which came to the world through Jesus Christ.

Verses 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 ( 1 Peter. 1:23 ) 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.
