Of righteousness, because I go to my Father,.... The "righteousness" here spoken of, does, in the first sense of the word, design the personal righteousness of Christ. The Jews had traduced him as a wicked man, said he was a sinner himself, and a friend of publicans and sinners; that he was guilty of blasphemy and sedition, maintained a familiarity with Satan, yea, that he had a devil: now the Spirit of God, by the mouth of Peter, on the day of "Pentecost", proved, to the conviction of the Jews, that all this was slander; that Christ was an innocent, holy, and righteous person, and a man approved of God among them, as they themselves must be conscious of, Ac 2:22; of all which, his going to the Father, and being received by him, were a full proof and demonstration.
The effusion of the Spirit in that extraordinary manner upon the disciples, showed that he was gone to the Father, and had received from him the promise of the Holy Ghost, which he then shed abroad; and his going to the Father, and being set down by him at his right hand, made it clear that he came from him, and was no impostor; that he had acted the faithful and upright part, and was free from all the charges the Jews had laid against, him.
Moreover, this may also be very well understood of the mediatorial righteousness of Christ, which he, as the surety and Saviour of his people, was to work out and bring in for them, in obedience to the law of God; which required holiness of nature, perfection of obedience, and bearing its penalty, death; all which were complied with by Christ, and so the whole righteousness of the law was fulfilled by him; and which is imputed by God as the justifying righteousness of all that believe in Jesus; and the proof of his having wrought out this, lies in his going to the Father; for as this was the work he came about, the will of his Father he came to do, had he not done it, it is reasonable to think he would never have met with such a welcome from him: besides, the donation of the Spirit, in consequence of its being wrought out, most clearly demonstrates it: likewise in the ordinary work of the Spirit of God upon the souls of his people, he always convinces them of the necessity of a righteousness to justify them before God, to render them acceptable in his sight, and to give them a right to the heavenly glory; for to admit them without a righteousness, or any unrighteous persons there, would be contrary to the justice of God, disagreeable to his pure and holy nature, and destructive of the comfort and happiness of the saints.
He, the Spirit of God, convinces men of the insufficiency of their own righteousness for such purposes; that they have no righteousness that deserves the name of one, and that what they have will not justify them before God, and entitle them to heaven: and this he does, by showing them the corruption of their nature, their daily sins and infirmities, in thought, word, and deed; the purity of the divine perfections, and the spirituality and extensiveness of the law of God; which when a man is thoroughly apprized of, he can never hope for and expect justification before God by his own righteousness: hence the Spirit of God proceeds to convince men of the glory, excellency, fulness, and suitableness of the righteousness of Christ; which he does, by revealing it to them in the Gospel, setting it before them, and working faith in them to lay hold upon it; when they desire to be found in Christ, not having on their own, but his righteousness; which convictions appear by the mean thoughts they have of their own righteousness, by hungering after Christ's, by disclaiming all but his, by their constant mention of it, dependence on it, and satisfaction in it; and thus to convince of it, is the peculiar work of the Spirit, since naturally men are fond of their own righteousness, are ignorant of Christ's, and set against it.
