And I will pray to the Father. This was given as a remedy for soothing the grief which they might feel on account of Christ's absence; but at the same time, Christ promises that he will give them strength to keep his commandments; For otherwise the exhortation would have had little effect. He therefore loses no time in informing them that, though he be absent from them in body, yet he will never allow them to remain destitute of assistance; for he will be present with them by his Spirit. Here he calls the Spirit the gift of the Father, but a gift which he will obtain by his prayers; in another passage he promises that he will give the Spirit. If I depart, says he, I will send, Him to you, (John 16:7.) Both statements are true and correct; for in so far as Christ is our Mediator and Intercessor, he obtains from the Father the grace of the Spirit, but in so far as he is God, he bestows that grace from himself. The meaning of this passage therefore is: "I was given to you by the Father to be a Comforter, but only for a time; now, having discharged my office, I will pray to him to give another Comforter, who will not be for a short time, but will remain always with you." And he will, give you another Comforter. The word Comforter is here applied both to Christ and to the Spirit, and justly; for it is an office which belongs equally to both of them, to comfort and exhort us, and to guard us by their protection. Christ was the Protector of his disciples, so long as he dwelt in the world: and afterwards he committed them to the protection and guardianship of the Spirit. It may be asked, are we not still under the protection of Christ? The answer is easy. Christ is a continual Protector, but not in a visible way. So long as he dwelt in the world, he openly manifested himself as their Protector; but now he guards us by his Spirit. He calls the Spirit another Comforter, on account of the difference between the blessings which we obtain from both. The peculiar office of Christ was, to appease the wrath of God by atoning for the sins of the world, to redeem men from death, to procure righteousness and life; and the peculiar office of the Spirit is, to make us partakers not only of Christ himself, but of all his blessings. And yet there would be no impropriety in inferring from this passage a distinction of Persons; for there must be some peculiarity in which the Spirit differs from the Son so as to be another than the Son.

I will pray the Father - This refers to his intercession after his death and ascension to heaven, for this prayer was to be connected with their keeping his commandments. In what way he makes intercession in heaven for his people we do not know. The fact, however, is clearly made known, Romans 8:34; Hebrews 4:14-15; Hebrews 7:25. It is as the result of his intercession in heaven that we obtain all our blessings, and it is through him that our prayers are to be presented and made efficacious before God.
Another Comforter - Jesus had been to them a counsellor, a guide, a friend, while he was with them. He had instructed them, had borne with their prejudices and ignorance, and had administered consolation to them in the times of despondency. But he was about to leave them now to go alone into an unfriendly world. The other Comforter was to be given as a compensation for his absence, or to perform the offices toward them which he would have done if he had remained personally with them. And from this we may learn, in part, what is the office of the Spirit. It is to furnish to all Christians the instruction and consolation which would be given by the personal presence of Jesus, John 16:14. To the apostles it was particularly to inspire them with the knowledge of all truth, John 14:26; John 15:26. Besides this, he came to convince men of sin. See the notes at John 16:8-11. It was proper that such an agent should be sent into the world:
1. Because it was a part of the plan that Jesus should ascend to heaven after his death.
2. Unless some heavenly agent should be sent to carry forward the work of salvation, man would reject it and perish.
3. Jesus could not be personally and bodily present in all places with the vast multitudes who should believe on him. The Holy Spirit is omnipresent, and can reach them all. See the notes at John 16:7.
4. It was manifestly a part of the plan of redemption that each of the persons of the Trinity should perform his appropriate work the Father in sending his Son, the Son in making atonement and interceding, and the Spirit in applying the work to the hearts of men.
The word translated "Comforter" is used in the New Testament five times. In four instances it is applied to the Holy Spirit - John 14:16, John 14:26; John 15:26; John 16:7. In the other instance it is applied to the Lord Jesus - 1-John 2:1; "We have an advocate (Paraclete - Comforter) with the Father, Jesus Christ the righteous." It is used, therefore, only by John. The verb from which it is taken has many significations. Its proper meaning is to call one to us Acts 27:20; then to call one to aid us, as an advocate in a court; then to exhort or entreat, to pray or implore, as an advocate does, and to comfort or console, by suggesting reasons or arguments for consolation. The word "comforter" is frequently used by Greek writers to denote an advocate in a court; one who intercedes; a monitor, a teacher, an assistant, a helper. It is somewhat difficult, therefore, to fix the precise meaning of the word. It may be translated either advocate, monitor, teacher, or helper. What the office of the Holy Spirit in this respect is, is to be learned from what we are elsewhere told he does. We learn particularly from the accounts that our Saviour gives of his work that that office was:
1. to comfort the disciples; to be with them in his absence and to supply his place; and this is properly expressed by the word Comforter.
2. to teach them, or remind them of truth; and this might be expressed by the word monitor or teacher, John 14:26; John 15:26-27.
3. to aid them in their work; to advocate their cause, or to assist them in advocating the cause of religion in the world, and in bringing sinners to repentance; and this may be expressed by the word advocate, John 16:7-13. It was also by the Spirit that they were enabled to stand before kings and magistrates, and boldly to speak in the name of Jesus, Matthew 10:20. These seem to comprise all the meanings of the word in the New Testament, but no single word in our language expresses fully the sense of the original.
That he may abide with you for ever - Not that he should remain with you for a few years, as I have done, and then leave you, but be with you in all places to the close of your life. He shall be your constant guide and attendant.

I will pray the Father - After having made an atonement for the sin of the world, I will become the Mediator between God and man; and through my mediation and intercession shall all the blessings of grace and glory be acquired.
Another Comforter - The word παρακλητος signifies not only a comforter, but also an advocate, a defender of a cause, a counsellor, patron, mediator. Christ is thus termed, 1-John 2:1, where the common translation renders the word advocate. Christ is thus called, because he is represented as transacting the concerns of our souls with God; and for this cause, he tells us, he goes unto the Father, John 14:12. The Holy Spirit is thus called, because he transacts the cause of God and Christ with us, explains to us the nature and importance of the great atonement, shows the necessity of it, counsels us to receive it, instructs us how to lay hold on it, vindicates our claim to it, and makes intercessions in us with unutterable groanings. As Christ acted with his disciples while he sojourned with them, so the Holy Ghost acts with those who believe in his name.
For ever - As the death and atonement of Christ will be necessary to man till the conclusion of the world, so the office of the Holy Spirit must be continued among men till the end of time: therefore says Christ, he shall continue with you for ever, teaching, comforting, advising, defending, and interceding for you and for all my followers to the end of time.

And I will pray the Father,...., Here Christ speaks as Mediator, and promises his disciples, that he would intercede for them with the Father; which is designed as an encouragement to them to ask for what they want, in his name, and to comfort their hearts, which were troubled at the news of his departure from them;
and he shall give you another Comforter. This is no inconsiderable proof of a trinity of persons in the Godhead; here is the Father prayed unto, the Son in human nature praying, and the Holy Ghost the Comforter prayed for; who is the gift of the Father, through the prevalent mediation of the Son, and is another "Comforter"; distinct from the Messiah, to whom reference is here had! One of the names of the Messiah, with the Jews, is (u), "a Comforter"; such an one Jesus had been to his disciples; and now he was about to leave them, and for their support under their sorrows, he promises to use his interest with his Father, that he would give them another Comforter, meaning the Spirit, who performs this his work and office, by taking of the things of Christ, and showing them to his people; by shedding abroad the love of the Father, and of the Son, into their hearts; by opening and applying the precious promises of the Gospel to them; by being a spirit of adoption in them; and by abiding with them as the seal, earnest, and pledge of their future glory; and with this view Christ promises to pray for him,
that he may abide with you for ever: not a few years only, as I have done, but as long as you live; and with all those that shall succeed you in the work of the ministry, and with the church, and all true believers unto the end of the world: this is a proof of the saints' final perseverance. When we consider these words, in connection with the preceding exhortation, to keep the commands of Christ, and as an encouragement so to do, it brings to mind a saying of R. Eliezer ben Jacob (w);
"he that does one commandment gets for himself , , the very word here used, "one advocate", or "comforter"; and he that transgresses one command, gets for himself one accuser.''
But though the word signifies both an advocate and a comforter, the latter seems to be the meaning of it here, as being more suited to the disconsolate condition of the disciples.
(u) T. Hieros. Beracot, fol. 5. 1. T. Bab. Sanhedrin, fol. 98. 2. Echa Rabbati, fol. 50. 2. (w) Pirke Abot, c. 4. sect. 11.

I will pray the Father. Rather, "request." The Greek word is not the one used when we are bidden to pray. The creature prays; the Son requests.
He shall give you another Comforter. The Holy Spirit; the Helper. The latter word more nearly expresses the idea of the Greek term than the word "Comforter."
Abide with you for ever. The Lord had been with them over three years, but is about to depart. Henceforth he will abide with them, not in person, but by the Holy Spirit that he shall send. Through this agency he will be with his people "always."

And I will ask the Father - John 14:21, shows the connection between this and the preceding verses. And he will give you another Comforter - The Greek word signifies also an advocate, instructer, or encourager. Another - For Christ himself was one. To remain with you for ever - With you, and your followers in faith, to the end of the world.
