And what he hath seen and heard. John proceeds in the discharge of his office; for, in order to procure disciples for Christ, he commends Christ's doctrine as certain, because he utters nothing but what he has received from the Father. Seeing and hearing are contrasted with doubtful opinions, unfounded rumors, and every kind of falsehoods; for he means that Christ teaches nothing but what has been fully ascertained. But some one will say that little credit is due to him who has nothing but what he has heard. I reply, this word denotes that Christ has been taught by the Father, so that he brings forward nothing but what is divine, or, in other words, what has been revealed to him by God. Now this belongs to the whole person of Christ, so far as the Father sent him into the world as His ambassador and interpreter. He afterwards charges the world with ingratitude, in basely and wickedly rejecting such an undoubted and faithful interpreter of God. In this way he meets the offense which might cause many to turn aside from the faith, and might hinder or retard the progress of many; for, as we are accustomed to depend too much on the judgment of the world, a considerable number of persons judge of the Gospel by the contempt of the world, or at least, where they see it everywhere rejected, they are prejudiced by that event, and are rendered more unwilling and more slow to believe. And, therefore, whenever we see such obstinacy in the world, let this admonition hold us in constant obedience to the Gospel, that it is truth which came from God. When he says that NO-MAN, receiveth his testimony, he means that there are very few and almost no believers, when compared with the vast crowd of unbelievers.

And what he hath seen - See John 3:11.
No man receiveth his testimony - The words "no man" are here to be understood in the sense of "few." Though his doctrine is pure, plain, sublime, yet "few," comparatively, received it in faith. Though multitudes came to him, drawn by various motives John 6:26, yet "few" became his "real" disciples, Matthew 26:56; Matthew 7:22.
His testimony - His doctrine. The truth to which he bears "witness" as having "seen" and "known" it, John 3:11. Often many persons "appear" for a time to become the followers of Christ, who in the end are seen to have known nothing of religion, Matthew 13:6; Luke 8:13.

And no man receiveth his testimony - Or, And this his testimony no man taketh up. That is, the testimony which John had borne to the Jews, that Jesus was the promised Messiah. No man taketh up. - No person is found to tread in my steps, and to publish to the Jews that this is the Christ, the Savior of the world. See this sense of the original fully proved and vindicated by Kypke in loc.

And what he hath (z) seen and heard, that he testifieth; and (a) no man receiveth his testimony.
(z) What he knows fully and perfectly.
(a) That is, very few.

And what he hath seen and heard,.... Of the Father, of his mind and will, of his purposes and promises, of his love, grace, and mercy, in the council and covenant of peace, lying in his bosom, and being privy to all his secrets. The phrases express the clear and perfect knowledge Christ has of all truths and doctrines; he having all the treasures of wisdom and knowledge in him.
That he testifieth; fully, freely, and faithfully; withholds nothing, but declares the whole counsel of God; and is deservedly called the faithful witness, Revelation 1:5.
And no man receiveth his testimony; though it was the testimony of God, which is greater than that of man; yet few, and which were next to none at all, gave any heed or credit to it; few or none among the Jews, or among the disciples of John, or even among those that followed Christ. John, and his disciples, widely differed; they thought that all men came to Christ, and believed in him; and John thought few or none, in comparison of the numbers he could have wished, did: and indeed, no one person can receive the testimony of Christ, and believe in him, unless it be given him from above, by the grace of God: for the natural man receives not divine and spiritual things; see John 3:11.

what he hath seen and heard--(See on John 3:11 and John 1:18).
and no man receiveth, &c.--John's disciples had said, "All come to Him" (John 3:26). The Baptist here virtually says, Would it were so, but alas! they are next to "none" [BENGEL]. They were far readier to receive himself, and obliged him to say, I am not the Christ, and he seems pained at this.

No man receiveth his testimony. So few at that time that those who received were as nothing in contrast with the others.

No man - None comparatively, exceeding few; receiveth his testimony - With true faith.
