And this is life eternal, that they might know thee the {b} only true God, and Jesus Christ, whom thou hast sent.

(b) He calls the Father the only true God in order to set him against all false gods, and to include himself and the Holy Spirit, for he immediately joins the knowledge of the Father and the knowledge of himself together, and according to his accustomed manner sets forth the whole Godhead in the person of the Father. So is the Father alone said to be King, immortal, wise, dwelling in light which no man can attain unto, and invisible; Ro 16:27; 1Ti 1:17.

People's New Testament

17:3 This life is eternal, that they might know thee, etc. The knowledge of God as manifested in Jesus Christ is the first requisite to salvation and life eternal. They key to that knowledge is faith and love.

Wesley's Notes

17:3 To know - By loving, holy faith, thee the only true God - The only cause and end of all things; not excluding the Son and the Holy Ghost, no more than the Father is excluded from being Lord, 1Cor 8:6; but the false gods of the heathens; and Jesus Christ - As their prophet, priest, and king: this is life eternal - It is both the way to, and the essence of, everlasting happiness.

Here the terms are used in their strict signification-"Jesus," because He "saves His people from their sins"; "Christ," as anointed with the measureless fulness of the Holy Ghost for the exercise of His saving offices (see on [1874]Mt 1:16); "Whom Thou hast sent," in the plenitude of Divine Authority and Power, to save. "The very juxtaposition here of Jesus Christ with the Father is a proof, by implication, of our Lord's Godhead. The knowledge of God and a creature could not be eternal life, and such an association of the one with the other would be inconceivable" [Alford].

Matthew Henry's Concise Commentary

17:1-5 Our Lord prayed as a man, and as the Mediator of his people; yet he spoke with majesty and authority, as one with and equal to the Father. Eternal life could not be given to believers, unless Christ, their Surety, both glorified the Father, and was glorified of him. This is the sinner's way to eternal life, and when this knowledge shall be made perfect, holiness and happiness will be fully enjoyed. The holiness and happiness of the redeemed, are especially that glory of Christ, and of his Father, which was the joy set before him, for which he endured the cross and despised the shame; this glory was the end of the sorrow of his soul, and in obtaining it he was fully satisfied. Thus we are taught that our glorifying God is needed as an evidence of our interest in Christ, through whom eternal life is God's free gift.

Matthew Henry's Whole Bible Commentary

Chapter 17

This chapter is a prayer, it is the Lord's prayer, the Lord Christ's prayer. There was one Lord's prayer which he taught us to pray, and did not pray himself, for he needed not to pray for the forgiveness of sin; but this was properly and peculiarly his, and suited him only as a Mediator, and is a sample of his intercession, and yet is of use to us both for instruction and encouragement in prayer. Observe, I. The circumstances of the prayer (v. 1). II. The prayer itself. 1. He prays for himself (v. 1-5). 2. He prays for those that are his. And in this see, (1.) The general pleas with which he introduces his petitions for them (v. 6-10). (2.) The particular petitions he puts up for them [1.] That they might be kept (v. 11-16). [2.] That they might be sanctified (v. 17-19). [3.] That they might be united (v. 11 and 20-23). [4.] That they might be glorified (v. 24-26).

Verses 1-5

Here we have, I. The circumstances of this prayer, v. 1. Many a solemn prayer Christ made in the days of his flesh (sometimes he continued all night in prayer), but none of his prayers are recorded so fully as this. Observe,

1. The time when he prayed this prayer; when he had spoken these words, had given the foregoing farewell to his disciples, he prayed this prayer in their hearing; so that, (1.) It was a prayer after a sermon; when he had spoken from God to them, he turned to speak to God for them. Note, Those we preach to we must pray for. He that was to prophesy upon the dry bones was also to pray, Come, O breath, and breathe upon them. And the word preached should be prayed over, for God gives the increase. (2.) It was a prayer after sacrament; after Christ and his disciples had eaten the passover and the Lord's supper together, and he had given them a suitable exhortation, he closed the solemnity with this prayer, that God would preserve the good impressions of the ordinance upon them. (3.) It was a family-prayer. Christ's disciples were his family, and, to set a good example before the masters of families, he not only, as the son of Abraham, taught his household (Gen. 18:19), but, as a son of David, blessed his household (2 Sa. 6:20), prayed for them and with them. (4.) It was a parting prayer. When we and our friends are parting, it is good to part with prayer, Acts 20:36. Christ was parting by death, and that parting should be sanctified and sweetened by prayer. Dying Jacob blessed the twelve patriarchs, dying Moses the twelve tribes, and so, here, dying Jesus the twelve apostles. (5.) It was a prayer that was a preface to his sacrifice, which he was now about to offer on earth, specifying the favours and blessings designed to be purchased by the merit of his death for those that were his; like a deed leading the uses of a fine, and directing to what intents and purposes it shall be levied. Christ prayed then as a priest now offering sacrifice, in the virtue of which all prayers were to be made. (6.) It was a prayer that was a specimen of his intercession, which he ever lives to make for us within the veil. Not that in his exalted state he addresses himself to his Father by way of humble petition, as when he was on earth. No, his intercession in heaven is a presenting of his merit to his Father, with a suing out of the benefit of it for all his chosen ones.

2. The outward expression of fervent desire which he used in this prayer: He lifted up his eyes to heaven, as before (ch. 11:41); not that Christ needed thus to engage his own attention, but he was pleased thus to sanctify this gesture to those that use it, and justify it against those that ridicule it. It is significant of the lifting up of the soul to God in prayer, Ps. 25:1. Sursum corda was anciently used as a call to prayer, Up with your hearts, up to heaven; thither we must direct our desires in prayer, and thence we must expect to receive the good things we pray for.

II. The first part of the prayer itself, in which Christ prays for himself. Observe here,

1. He prays to God as a Father: He lifted up his eyes, and said, Father. Note, As prayer is to be made to God only, so it is our duty in prayer to eye him as a Father, and to call him our Father. All that have the Spirit of adoption are taught to cry Abba, Father, v. 25. For it will be of great use to us in prayer, both for direction and for encouragement, to call God as we hope to find him.

2. He prayed for himself first. Though Christ, as God, was prayed to, Christ, as man, prayed; thus it became him to fulfill all righteousness. It was said to him, as it is said to us, Ask, and I will give thee, Ps. 2:8. What he had purchased he must ask for; and shall we expect to have what we never merited, but have a thousand times forfeited, unless we pray for it? This puts an honour upon prayer, that it was the messenger Christ sent on his errands, the way in which even he corresponded with Heaven. It likewise gives great encouragement to praying people, and cause to hope that even the prayer of the destitute shall not be despised; time was when he that is advocate for us had a cause of his own to solicit, a great cause, on the success of which depended all his honour as Mediator; and this he was to solicit in the same method that is prescribed to us, by prayers and supplications (Heb. 5:7), so that he knows the heart of a petitioner (Ex. 23:9), he knows the way. Now observe, Christ began with prayer for himself, and afterwards prayed for his disciples; this charity must begin at home, though it must not end there. We must love and pray for our neighbor as ourselves, and therefore must in a right manner love and pray for ourselves first. Christ was much shorter in his prayer for himself than in his prayer for his disciples. Our prayers for the church must not be crowded into a corner of our prayers; in making supplication for all saints, we have room enough to enlarge, and should not straiten ourselves. Now here are two petitions which Christ puts up for himself, and these two are one-that he might be glorified. But this one petition, Glorify thou me, is twice put up, because it has a double reference. To the prosecution of his undertaking further: Glorify me, that I may glorify thee, in doing what is agreed upon to be yet done, v. 1-3. And to the performance of his undertaking hitherto: "Glorify me, for I have glorified thee. I have done my part, and now, Lord, do thine," v. 4, 5.

(1.) Christ here prays to be glorified, in order to his glorifying God (v. 1): Glorify thy Son according to thy promise, that thy Son may glorify thee according to his understanding. Here observe,

[1.] What he prays for-that he might be glorified in this world: "The hour is come when all the powers of darkness will combine to vilify thy Son; now, Father, glorify him." The Father glorified the Son upon earth, First, Even in his sufferings, by the signs and wonders which attended them. When they that came to take him were thunder-struck with a word,-when Judas confessed him innocent, and sealed that confession with his own guilty blood,-when the judge's wife asleep, and the judge himself awake, pronounced him righteous,-when the sun was darkened, and the veil of the temple rent, then the Father not only justified, but glorified the Son. Nay, Secondly, Even by his sufferings; when he was crucified, he was magnified, he was glorified, ch. 13:31. It was in his cross that he conquered Satan and death; his thorns were a crown, and Pilate in the inscription over his head wrote more than he thought. But, Thirdly, Much more after his sufferings. The Father glorified the Son when he raised him from the dead, showed him openly to chosen witnesses, and poured out the Spirit to support and plead his cause, and to set up his kingdom among men, then he glorified him. This he here prays for, and insists upon.

[2.] What he pleads to enforce this request.

First, He pleads relation: Glorify thy Son; thy Son as God, as Mediator. It is in consideration of this that the heathen are given him for his inheritance; for thou art my Son, Ps. 2:7, 8. The devil had tempted him to renounce his sonship with an offer of the kingdoms of this world; but he rejected the offer with disdain, and depended upon his Father for his preferment, and here applies himself to him for it. Note, Those that have received the adoption of sons may in faith pray for the inheritance of sons; if sanctified, then glorified: Father, glorify thy Son.

Secondly, He pleads the time: The hour is come; the season prefixed to an hour. The hour of Christ's passion was determined in the counsel of God. He had often said his hour was not yet come; but now it was come, and he knew it. Man knows not his time (Eccl. 9:12), but the Son of man did. He calls it this hour (ch. 12:27), and here, the hour; compare Mk. 14:35; ch. 16:21. For the hour of the Redeemer's death, which was also the hour of the Redeemer's birth, was the most signal and remarkable hour, and, without doubt, the most critical, that ever was since the clock of time was first set a going. Never was there such an hour as that, nor did ever any hour challenge such expectations of it before, nor such reflections upon it after. 1. "The hour is come in the midst of which I need to be owned." Now is the hour when this grand affair is come to a crisis; after many a skirmish the decisive battle between heaven and hell is now to be fought, and that great cause in which God's honour and man's happiness are together embarked must now be either won or lost for ever. The two champions David and Goliath, Michael and the dragon, are now entering the lists; the trumpet sounds for an engagement that will be irretrievably fatal either to the one or to the other: "Now glorify thy Son, now give him victory over principalities and powers, now let the bruising of his heel be the breaking of the serpent's head, now let thy Son be so upheld as not to fail nor be discouraged." When Joshua went forth conquering and to conquer, it is said, The Lord magnified Joshua; so he glorified his Son when he made the cross his triumphant chariot. 2. "The hour is come in the close of which I expect to be crowned; the hour is come when I am to be glorified, and, set at thy right hand." Betwixt him and that glory there intervened a bloody scene of suffering; but, being short, he speaks as if he made little of it: The hour is come that I must be glorified; and he did not expect it till then. Good Christians in a trying hour, particularly a dying hour, may thus plead: "Now the hour is come, stand by me, appear for me, now or never: now the earthly tabernacle is to be dissolved, the hour is come that I should be glorified." 2 Co. 5:1.

Thirdly, He pleads the Father's own interest and concern herein: That thy Son may also glorify thee; for he had consecrated his whole undertaking to his Father's honour. He desired to be carried triumphantly through his sufferings to his glory, that he might glorify the Father two ways:-1. By the death of the cross, which he was now to suffer. Father, glorify thy name, expressed the great intention of his sufferings, which was to retrieve his Father's injured honour among men, and, by his satisfaction, to come up to the glory of God, which man, by his sin, came short of: "Father, own me in my sufferings, that I may honour thee by them." 2. By the doctrine of the cross, which was now shortly to be published to the world, by which God's kingdom was to be re-established among men. He prays that his Father would so grace his sufferings, and crown them, as not only to take off the offence of the cross, but to make it, to those that are saved, the wisdom of God and the power of God. If God had not glorified Christ crucified, by raising him from the dead, his whole undertaking had been crushed; therefore glorify me, that I may glorify thee. Now thereby he hath taught us, (1.) What to eye and aim at in our prayers, in all our designs and desires-and that is, the honour of God. It being our chief end to glorify God, other things must be sought and attended to in subordination and subserviency to the Lord. "Do this and the other for thy servant, that thy servant may glorify thee. Give me health, that I may glorify thee with my body; success, that I may glorify thee with my estate," etc. Hallowed be thy name must be our first petition, which must fix our end in all our other petitions, 1 Peter 4:11. (2.) He hath taught us what to expect and hope for. If we sincerely set ourselves to glorify our Father, he will not be wanting to do that for us which is requisite to put us into a capacity of glorifying him, to give us the grace he knows sufficient, and the opportunity he sees convenient. But, if we secretly honour ourselves more than him, it is just with him to leave us in the hand of our own counsels, and then, instead of honouring ourselves, we shall shame ourselves.

Fourthly, He pleads his commission (v. 2, 3); he desires to glorify his Father, in conformity to, and in pursuance of, the commission given him: "Glorify thy Son, as thou hast given him power, glorify him in the execution of the powers thou hast given him," so it is connected with the petition; or, that thy Son may glorify thee according to the power given him, so it is connected with the plea. Now see here the power of the Mediator.

a. The origin of his power: Thou hast given him power; he has it from God, to whom all power belongs. Man, in his fallen state, must, in order to his recovery, be taken under a new model of government, which could not be erected but by a special commission under the broad seal of heaven, directed to the undertaker of that glorious work, and constituting him sole arbitrator of the grand difference that was, and sole guarantee of the grand alliance that was to be, between God and man; so as to this office, he received his power, which was to be executed in a way distinct from his power and government as Creator. Note, The church's king is no usurper, as the prince of this world is; Christ's right to rule is incontestable.

b. The extent of his power: He has power over all flesh. (a.) Over all mankind. He has power in and over the world of spirits, the powers of the upper and unseen world are subject to him (1 Peter 3:22); but, being now mediating between God and man, he here pleads his power over all flesh. They were men whom he was to subdue and save; out of that race he had a remnant given him, and therefore all that rank of beings was put under his feet. (b.) Over mankind considered as corrupt and fallen, for so he is called flesh, Gen. 6:3. If he had not in this sense been flesh, he had not needed a Redeemer. Over this sinful race the Lord Jesus has all power; and all judgment, concerning them, is committed to him; power to bind or loose, acquit or condemn; power on earth to forgive sins or not. Christ, as Mediator, has the government of the whole world put into his hand; he is king of nations, has power even over those that know him not, nor obey his gospel; whom he does not rule, he over-rules, Ps. 22:28; 72:8; Mt. 28:18; ch. 3:35.

c. The grand intention and design of this power: That he should give eternal life to as many as thou hast given him. Here is the mystery of our salvation laid open.

(a.) Here is the Father making over the elect to the Redeemer, and giving them to him as his charge and trust; as the crown and recompence of his undertaking. He has a sovereign power over all the fallen race, but a peculiar interest in the chosen remnant; all things were put under his feet, but they were delivered into his hand.

(b.) Here is the Son undertaking to secure the happiness of those that were given him, that he would give eternal life to them. See how great the authority of the Redeemer is. He has lives and crowns to give, eternal lives that never die, immortal crowns that never fade. Now consider how great the Lord Jesus is, who has such preferments in his gift; and how gracious he is in giving eternal life to those whom he undertakes to save. [a.] He sanctifies them in this world, gives them the spiritual life which is eternal life in the bud and embryo, ch. 4:14. Grace in the soul is heaven in that soul. [b.] He will glorify them in the other world; their happiness shall be completed in the vision and fruition of God. This only is mentioned, because it supposes all the other parts of his undertaking, teaching them, satisfying for them, sanctifying them, and preparing them for that eternal life; and indeed all the other were in order to this; we are called to his kingdom and glory, and begotten to the inheritance. What is last in execution was first in intention, and that is eternal life.

(c.) Here is the subserviency of the Redeemer's universal dominion to this: He has power over all flesh, on purpose that he might give eternal life to the select number. Note, Christ's dominion over the children of men is in order to the salvation of the children of God. All things are for their sakes, 2 Co. 4:15. All Christ's laws, ordinances, and promises, which are given to all, are designed effectually to convey spiritual life, and secure eternal life, to all that were given to Christ; he is head over all things to the church. The administration of the kingdoms of providence and grace are put into the same hand, that all things may be made to concur for good to the called.

d. Here is a further explication of this grand design (v. 3): "This is life eternal, which I am empowered and have undertaken to give, this is the nature of it, and this the way leading to it, to know thee the only true God, and all the discoveries and principles of natural religion, and Jesus Christ whom, thou has sent, as Mediator, and the doctrines and laws of that holy religion which he instituted for the recovery of man out of his lapsed state." Here is,

(a.) The great end which the Christian religion sets before us, and that is, eternal life, the happiness of an immortal soul in the vision and fruition of an eternal God. This he was to reveal to all, and secure to all that were given him. By the gospel life and immortality are brought to light, are brought to hand, a life which transcends this as much in excellency as it does in duration.

(b.) The sure way of attaining this blessed end, which is, by the right knowledge of God and Jesus Christ: "This is life eternal, to know thee," which may be taken two ways-[a.] Life eternal lies in the knowledge of God and Jesus Christ; the present principle of this life is the believing knowledge of God and Christ; the future perfection of that life will be the intuitive knowledge of God and Christ. Those that are brought into union with Christ, and live a life of communion with God in Christ, know, in some measure, by experience, what eternal life is, and will say, "If this be heaven, heaven is sweet." See Ps. 17:15. [b.] The knowledge of God and Christ leads to life eternal; this is the way in which Christ gives eternal life, by the knowledge of him that has called us (2 Peter 1:3), and this is the way in which we come to receive it. The Christian religion shows us the way to heaven, First, By directing us to God, as the author and felicity of our being; for Christ died to bring us to God. To know him as our Creator, and to love him, obey him, submit to him, and trust in him, as our owner ruler, and benefactor,-to devote ourselves to him as our sovereign Lord, depend upon him as our chief good, and direct all to his praise as our highest end,-this is life eternal. God is here called the only true God, to distinguish him from the false gods of the heathen, which were counterfeits and pretenders, not from the person of the Son, of whom it is expressly said that he is the true God and eternal life (1 Jn. 5:20), and who in this text is proposed as the object of the same religious regard with the Father. It is certain there is but one only living and true God and the God we adore is he. He is the true God, and not a mere name or notion; the only true God, and all that ever set up as rivals with him are vanity and a lie; the service of him is the only true religion. Secondly, By directing us to Jesus Christ, as the Mediator between God and man: Jesus Christ, whom thou hast sent. If man had continued innocent, the knowledge of the only true God would have been life eternal to him; but now that he is fallen there must be something more; now that we are under guilt, to know God is to know him as a righteous Judge, whose curse we are under; and nothing is more killing than to know this. We are therefore concerned to know Christ as our Redeemer, by whom alone we can now have access to God; it is life eternal to believe in Christ; and this he has undertaken to give to as many as were given him. See ch. 6:39 40. Those that are acquainted with God and Christ are already in the suburbs of life eternal.
