John testifieth. He now relates what was the preaching of John. By using the verb testifieth (marturei) in the present tense, [1] he denotes a continued act, and certainly this doctrine must be continually in force, as if the voice of John were continually resounding in the ears of men. In the same manner he afterwards uses the word cry, to intimate that the doctrine of John was in no degree obscure or ambiguous, and that he did not mutter among a few men, [2] but openly, and with a loud voice, preached Christ. The first sentence is intended to convey the statement, that he was sent for the sake of Christ, and therefore that it would have been unreasonable that he should be exalted, while Christ was lying low. This is he of whom I spoke. By these words he means that his intention was, from the beginning, to make Christ known, and that this was the design of his public discourses; as, indeed, there was no other way in which he could discharge his office as ambassador than by calling his disciples to Christ. Who, coming after me. Though John the Baptist was older than Christ by a few months, yet he does not now speak of age; but as he had discharged the office of prophet for a short period before Christ appeared in public, so he makes himself the predecessor with respect to time. With respect, therefore, to public manifestation, Christ came after John the Baptist. The words which follow might be literally rendered, he was made before me, for he was before me; but the meaning is, that Christ was justly preferred to John, because he was more excellent. He therefore surrenders his office to Christ and -- as the proverb runs -- "delivers to him the torch," or gives way to him as his successor. But as he arose later in the order of time, John reminds his hearers that this is no reason why he should not be preferred to himself, as his rank deserved. Thus, all who are superior to others, either in the gifts of God or in any degree of honor, must remain in their own rank, so as to be placed below Christ.

Footnotes

1 - "En usant du verbe du temps present, a scavoir, Rend tesmoignage, et on pas, Rendoit;" -- "by using the verb in the present tense, giveth testimony, and not gave testimony."

2 - "Qu'il n'a point parle entre ses dents, et communique la chose comme en secret a peu de gens;" -- "that he did not speak between his teeth, and communicate the matter, as it were secretly, to a few persons."

John bare witness of him - The evangelist now returns to the testimony of John the Baptist. He had stated that the Word became incarnate, and he now appeals to the testimony of John to show that, thus incarnate, he was the Messiah.
He that cometh after me - He of whom I am the forerunner, or whose way I am come to prepare. See the notes at Matthew 3:3.
Is preferred before me - Is superior to me. Most critics have supposed that the words translated "is preferred" relate to "time," and not to "dignity;" meaning that though he came after him publicly, being six months younger than John, as well as entering on his work after John, yet that he had existed long before him. Most, however, have understood it more correctly, as our translators seem to have done, as meaning, He was worthy of more honor than I am.
He was before me - This can refer to nothing but his pre-existence, and can be explained only on the supposition that he existed before John, or, as the evangelist had before shown, from the beginning. He came "after" John in his public ministry and in his human nature, but in his divine nature he had existed long before John had a being - from eternity. We may learn here that it is one mark of the true spirit of a minister of Christ to desire and feel that Christ is always to be preferred to ourselves. We should keep ourselves out of view. The great object is to hold up the Saviour; and however much ministers may be honored or blessed, yet they should lay all at the feet of Jesus, and direct all men to him as the undivided object of affection and honor. It is the business of every Christian, as well as of every Christian minister, to be a witness for Christ, and to endeavor to convince the world that he is worthy of confidence and love.

Of him - The glorious personage before mentioned: John the Baptist, whose history was well known to the persons to whom this Gospel came in the beginning, bare witness; and he cried, - being deeply convinced of the importance and truth of the subject, he delivered his testimony with the utmost zeal and earnestness, - saying, This is he of whom I spake, He that cometh after me - for I am no other than the voice of the crier in the wilderness, Isaiah 40:3, the forerunner of the Messiah.
Was before me - Speaking by the prophets, and warning your fathers to repent and return to God, as I now warn you; for he was before me - he was from eternity, and from him I have derived both my being and my ministry.

(8) John bare witness of him, and cried, saying, This was he of whom I spake, He that cometh (b) after me is preferred (c) before me: for he was before me.
(8) John is a faithful witness of the excellency of Christ.
(b) That is, "He before whom I am sent to prepare him the way": so that these words refer to the time of his calling, and not of his age, for John was six months older than Christ.
(c) This sentence has in it a turning of the reason as we call it, as one would say, a setting of that first which should be last, and that last which should be first: for in plain speech it is this, "He that comes after me, is better than I am, for he was before me." We find a similar turning of the reason in (Luke 7:47): "Many sins are forgiven her, because she loved much", which is this much to say, "She loved much, because many sins are forgiven her."

John bare witness of him,.... Which was his office and business, for which purpose he was sent, John 1:6.
and cried; this agrees with his work and office, according to the prophecy of him in Isaiah 40:3 and with the time of his ministry, the year of jubilee; and with the nature of his ministry, which was clear, open, and public; and performed with vigour, and in a powerful manner, with much assurance and certainty, with boldness and intrepidity, and with great zeal and fervency, and in an evangelical way; for it was such a cry as debased the creature, and exalted Christ:
this was he, of whom I spake; when he first entered upon his ministry and baptism, before he saw Christ, or baptized him; see Matthew 3:11.
he that cometh after me; for Christ came into the world after John; he was born six months after him; he came after him to be baptized by him, and attended on his ministry; and came later into the public ministry than he did,
is preferred before me; by God, the Father, in setting him up as Mediator; constituting him the head of the church; causing a fulness of grace to dwell in him; appointing him the Saviour of his people; and ordaining him judge of quick and dead. And by the prophets, who spake much of him, and sparingly of John; and of him as the Messiah and Saviour, and of John only as his harbinger: and by John himself, who represents him as coming from above, and as above all; and himself as of the earth, earthly: and by all Gospel ministers, and every true believer; and good reason there is for it:
for he was before me; which cannot be meant of honour and dignity; for this is expressed before; and it would be proving one thing by the same: nor of his birth, as man; for John in that sense was before him, being born before him; besides, being born before another, is no proof of superior worth; others were born before John, whom he yet excelled: but of his eternal existence, as the word, and Son of God, who was before John, or any of the prophets; before Abraham, and Noah, and Adam, or any creature whatever: the Arabic and Persic versions read, "for he was more ancient than me"; being from everlasting, from the beginning, or ever the earth was.

As to the order of time and entrance on his work, Christ came after John, but in every other way he was before him. The expression clearly shows that Jesus had existence before he appeared on earth as man. All fulness dwells in him, from which alone fallen sinners have, and shall receive, by faith, all that renders them wise, strong, holy, useful, and happy. Our receivings by Christ are all summed up in this one word, grace; we have received "even grace," a gift so great, so rich, so invaluable; the good will of God towards us, and the good work of God in us. The law of God is holy, just, and good; and we should make the proper use of it. But we cannot derive from it pardon, righteousness, or strength. It teaches us to adorn the doctrine of God our Saviour, but it cannot supply the place of that doctrine. As no mercy comes from God to sinners but through Jesus Christ, no man can come to the Father but by him; no man can know God, except as he is made known in the only begotten and beloved Son.

A SAYING OF THE BAPTIST CONFIRMATORY OF THIS. (John 1:15)
after me--in official manifestation.
before me--in rank and dignity.
for he was before me--in existence; "His goings forth being from of old, from everlasting" (Micah 5:2). (Anything lower than this His words cannot mean); that is, "My Successor is my Superior, for He was my Predecessor." This enigmatic play upon the different senses of the words "before" and "after" was doubtless employed by the Baptist to arrest attention, and rivet the thought; and the Evangelist introduces it just to clinch his own statements.

John bare witness. At the time of Christ's baptism when the Spirit descended. See John 1:33.

John cried - With joy and confidence; This is he of whom I said - John had said this before our Lord's baptism, although he then knew him not in person: he knew him first at his baptism, and afterward cried, This is he of whom I said. &c. He is preferred before me - in his office: for he was before me - in his nature.
