(8) And when he is come, he will reprove the world.--Better, as in margin, convince the world. (Comp. John 3:20; John 8:46.) The only other passages where it occurs in the Gospels are in Matthew 18:15, and Luke 3:19. It is not in the better reading of John 8:9; but it occurs not unfrequently in the Epistles. (See especially Note on 1Corinthians 14:24.) This conviction of the world is by witness concerning Christ (John 15:26). It is the revelation to the hearts of men of the character and work of Christ, and, therefore, a refutation of the evil in their hearts. The result of this conviction is two-fold, according as men embrace it, accept its chastening discipline, and are saved by it; or reject it, and in the rejection harden their hearts, and are thus condemned by it. (Comp. 2Corinthians 2:15-16.) The effect of St. Peter's sermon on the Day of Pentecost is the first great historical comment on this verse; but the comment is continued in the whole history of the Church's work. The remainder of the verse enumerates the three steps in this conviction, which are more fully defined in the three following verses.

Verse 8. - And he, when he is come (ἐλθών). A right royal assurance. The Holy Spirit will come, as my grace and the result of my sending. He will convict the world. Little doubt is now entertained that this ἔλεγχος implies the refutation of error, the discovery of wrong-doing, the bringing it home to the person convinced, and thus convicted (John 3:20; John 8:9, 46; 1 Corinthians 14:24; Titus 1:9; James 2:9); making such a one see that he is open to the condemnation of conscience, or of men, or of the Law of God. This conviction may in some cases lead to conversion and deliverance, but is distinct from it, and sometimes also may issue after such a manifestation in hardness and impenitence. The patristic interpretation (Authorized Version and Hengstenberg), "He will reprove," might pass as a fair translation of the word, in its reference to sin, but would have small meaning as applied to righteousness or judgment. Meyer, Godet, Luthardt, Lange, Westcott, Stier, and Moulton agree that ἔλεγξει means more than "reprove," less than "convince." The world is spoken of, not Jews merely, or their leaders. Humanity itself, with its false standards of judgment, and its self-complacency, is to be convicted of being in the wrong; all kings, princes, potentates, priests, and publicans, who are out of harmony with God, wilt be convicted by the Paraclete. The conviction of the world is threefold - in respect of sin, in respect of righteousness, and in respect of judgment. The three great categories of thought, custom, and conduct; the three themes where the world is in infinite need of being compelled to see that it is altogether in the wrong. The disciples are to overcome the whole world by the intensity with which they will be instrumentally the occasion of this conviction. The world under the depressing and distracting influence of its own principles, as well as its passions, has misconceived the whole nature of "sin," the entire mystery of "righteousness," the certainty of retribution, and the things and principles on which condign "judgment" must fall. The Advocate, the Divine, indwelling Spirit of the truth, whom Christ will send into his disciples as compensation for his own absence, will through them do this strange and tremendous work. Our Lord does not here promise the conversion of mankind, but such a conviction that the blessed consequence may follow. The first great step will be taken.

16:7-15 Christ's departure was necessary to the Comforter's coming. Sending the Spirit was to be the fruit of Christ's death, which was his going away. His bodily presence could be only in one place at one time, but his Spirit is every where, in all places, at all times, wherever two or three are gathered together in his name. See here the office of the Spirit, first to reprove, or to convince. Convincing work is the Spirit's work; he can do it effectually, and none but he. It is the method the Holy Spirit takes, first to convince, and then to comfort. The Spirit shall convince the world, of sin; not merely tell them of it. The Spirit convinces of the fact of sin; of the fault of sin; of the folly of sin; of the filth of sin, that by it we are become hateful to God; of the fountain of sin, the corrupt nature; and lastly, of the fruit of sin, that the end thereof is death. The Holy Spirit proves that all the world is guilty before God. He convinces the world of righteousness; that Jesus of Nazareth was Christ the righteous. Also, of Christ's righteousness, imparted to us for justification and salvation. He will show them where it is to be had, and how they may be accepted as righteous in God's sight. Christ's ascension proves the ransom was accepted, and the righteousness finished, through which believers were to be justified. Of judgment, because the prince of this world is judged. All will be well, when his power is broken, who made all the mischief. As Satan is subdued by Christ, this gives us confidence, for no other power can stand before him. And of the day of judgment. The coming of the Spirit would be of unspeakable advantage to the disciples. The Holy Spirit is our Guide, not only to show us the way, but to go with us by continued aids and influences. To be led into a truth is more than barely to know it; it is not only to have the notion of it in our heads, but the relish, and savour, and power of it in our hearts. He shall teach all truth, and keep back nothing profitable, for he will show things to come. All the gifts and graces of the Spirit, all the preaching, and all the writing of the apostles, under the influence of the Spirit, all the tongues, and miracles, were to glorify Christ. It behoves every one to ask, whether the Holy Spirit has begun a good work in his heart? Without clear discovery of our guilt and danger, we never shall understand the value of Christ's salvation; but when brought to know ourselves aright, we begin to see the value of the Redeemer. We should have fuller views of the Redeemer, and more lively affections to him, if we more prayed for, and depended on the Holy Spirit.And when he is come,.... The coming of the Spirit here, chiefly designs his descent upon the apostles, at the day of "Pentecost": as the things ascribed to him, and which were then done by him, clearly show; though it may also include his coming along with, and by the ministration of the Gospel, into the hearts of his people at conversion, in all after ages of time:

he will reprove the world of sin, of righteousness, and of judgment: by "the world" is principally meant, the Jews; the world among whom Christ personally was, who knew him not, disbelieved him, rejected him as the Messiah, hated and persecuted him, even unto death; though not to the exclusion of the Gentiles, the whole world that lies in wickedness; since both joined, and were concerned in these things, and reproved of them; which "reproving", as it may respect different persons, may intend both such reproofs and convictions, as are not attended with conversion, and issue in salvation; and such as are powerful, spiritual, and to saving purposes: the several things the Spirit of God is said to reprove of, being repeated in the following verses, with reasons or specifications annexed to them, will be there considered.
