that they know you... and Jesus Christ. Life consists in fellow- ship with God “who created us for Himself, so that our soul is restless unless it finds its rest in Him,’ as Augustine expressed it. Knowledge, here as So often in Scripture, means more than mere intellectual grasp; it involves affection and commitment as well. By placing Himself and the Father together as the source of eternal life, Christ affirms His own deity. See “True Knowledge of God" at Jer. 9:24.
Calvin (1560)
John 17:1-5 1. These words spake Jesus, and lifted up his eyes to heaven, and said, Father, the hour is come; glorify thy Son, that thy Son also may glorify thee: 2. As thou hast given him power over all flesh, that he may give eternal life to all whom thou hast given to him. 3. And this is eternal life, that they may know thee, the only true God, and him whom thou hast sent, Jesus Christ. 4. I have glorified thee on the earth; I have finished the work which thou gavest me to do. 5. And now, O Father, glorify thou me with thyself, with the glory which I had with thee before the world was. 1. These words spake Jesus. After having preached to the disciples about bearing the cross, the Lord exhibited to them those consolations, by relying on which they would be enabled to persevere. Having promised the coming of the Spirit, he raised them to a better hope, and discoursed to them about the splendor and glory of his reign. Now he most properly betakes himself to prayer; for doctrine has no power, if efficacy be not imparted to it from above. He, therefore, holds out an example to teachers, not to employ themselves only in sowing the word, but, by mingling their prayers with it, to implore the assistance of God, that his blessing may render their labor fruitful. In short, this passage of the Lord Jesus [107] Christ might be said to be the seal of the preceding doctrine, both that it might be ratified in itself, and that it might obtain full credit with the disciples. And lifted up his eyes to heaven. This circumstance related by John, that Christ prayed, lifting up his eyes to heaven, was an indication of uncommon ardor and vehemence; for by this attitude Christ testified that, in the affections of his mind, he was rather in heaven than in earth, so that, leaving men behind him, he converted familiarly with God. He looked towards heaven, not as if God's presence were confined to heaven, for He filleth also the earth, ( Jeremiah 23:24 ,) but because it is there chiefly that his majesty is displayed. Another reason was, that, by looking towards heaven, we are reminded that the majesty of God is far exalted above all creatures. It is with the same view that the hands are lifted up in prayer; for men, being by nature indolent and slow, and drawn downwards by their earthly disposition, need such excitements, or I should rather say, chariots, to raise them to heaven Yet if we desire actually to imitate Christ, we must take care that outward gestures do not express more than is in our mind, but that the inward feeling shall direct the eyes, the hands, the tongue, and every thing about us. We are told, indeed, that the publican, with downcast eyes, prayed aright to God, ( Luke 18:13 ,) but that is not inconsistent with what has now been stated; for, though he was confused and humbled on account of his sins, still this self-abasement did not prevent him from seeking pardon with full confidence. But it was proper that Christ should pray in a different manner, for he had nothing about him of which he ought to be ashamed; and it is certain that David himself prayed sometimes in one attitude, and sometimes in another, according to the circumstances in which he was placed. Father, the hour is come. Christ asks that his kingdom may be glorified, in order that he also may advance the glory of the Father. He says that the hour is come, because though, by miracles and by every kind of supernatural events, he had been manifested to be the Son of God, yet his spiritual kingdom was still in obscurity, but soon afterwards shone with full brightness. If it be objected, that never was there any thing less glorious than the death of Christ, which was then at hand, I reply, that in that death we behold a magnificent triumph which is concealed from wicked men; for there we perceive that, atonement having been made for sins, the world has been reconciled to God, the curse has been blotted out, and Satan has been vanquished. It is also the object of Christ's prayer, that his death may produce, through the power of the Heavenly Spirit, such fruit as had been decreed by the eternal purpose of God; for he says that the hour is come, not an hour which is determined by the fancy of men, but an hour which God had appointed. And yet the prayer is not superfluous, because, while Christ depends on the good pleasure of God, he knows that he ought to desire what God promised would certainly take place. True, God will do whatever he has decreed, not only though the whole world were asleep, but though it were opposed to him; but it is our duty to ask from him whatever he has promised, because the end and use [108] of promises is to excite us to prayer. That thy Son also may glorify thee. He means that there is a mutual connection between the advancement of his glory and of the glory of his Father; for why is Christ manifested, but that he may lead us to the Father? Hence it follows, that all the honor which is bestowed on Christ is so far from diminishing the honor of the Father, that it confirms it the more. We ought always to remember under what character Christ speaks in this passage; for we must not look only at his eternal Divinity, because he speaks as God manifested in the flesh, and according to the office of Mediator. 2. As thou hast given him. He again confirms the statement, that he asks nothing but what is agreeable to the will of the Father; as it is a constant rule o prayer not to ask more than God would freely bestow; for nothing is more contrary to reason, than to bring forward in the presence of God whatever we choose. Power over all flesh means the authority which was given to Christ, when the Father appointed him to be King and Head; but we must observe the end, which is, to give eternal life to all his people. Christ receives authority, not so much for himself as for the sake of our salvation; and, therefore, we ought to submit to Christ, not only that we may obey God, but because nothing is more lovely than that subjection, since it brings to us eternal life. To all whom thou hast given me. Christ does not say that he has been made Governor over the whole world, in order to bestow life on all without any distinction; but he limits this grace to those who have been given to him But how were they given to him? For the Father has subjected to him the reprobate. I reply, it is only the elect who belong to his peculiar flock, which he has undertaken to guard as a Shepherd. So then, the kingdom of Christ extends, no doubt, to all men; but it brings salvation to none but the elect, who with voluntary obedience follow the voice of the Shepherd; for the others are compelled by violence to obey him, till at length he utterly bruise them with his iron scepter. 3. And this is eternal life He now describes the manner of bestowing life, namely, when he enlightens the elect in the true knowledge of God; for he does not now speak of the enjoyment of life which we hope for, but only of the manner in which men obtain life And that this verse may be fully understood, we ought first to know that we are all in death, till we are enlightened by God, who alone is life Where he has shone, we possess him by faith, and, therefore, we also enter into the possession of life; and this is the reason why the knowledge of him is truly and justly called saving, or bringing salvation. [109] Almost every one of the words has its weight; for it is not every kind of knowledge that is here described, but that knowledge which forms us anew into the image of God from faith to faith, or rather, which is the same with faith, by which, having been engrafted into the body of Christ, we are made partakers of the Divine adoption, and heirs of heaven. [110] To know thee, and Jesus Christ whom thou hast sent. The reason why he says this is, that there is no other way in which God is known but in the face of Jesus Christ, who is the bright and lively image of Him. As to his placing the Father first, this does not refer to the order of faith, as if our minds, after having known God, afterwards descend to Christ; but the meaning is, that it is by the intervention of a Mediator that God is known. The only true God. Two epithets are added, true and only; because, in the first place, faith must distinguish God from the vain inventions of men, and embracing him with firm conviction, must never change or hesitate; and, secondly, believing that there is nothing defective or imperfect in God, faith must be satisfied with him alone. Some explain it, That they may know thee, who alone art God; but this is a poor interpretation. The meaning therefore is, That they may know thee alone to be the true God But it may be thought that Christ disclaims for himself the right and title of Divinity. Were it replied, that the name of God is quite as applicable to Christ as to the Father, the same question might be raised about the Holy Spirit; for if only the Father and the Son are God, the Holy Spirit is excluded from that rank, which is as absurd as the former. The answer is easy, if we attend to that manner of speaking which Christ uniformly employs throughout the Gospel of John, of which I have already reminded my readers so frequently, that they must have become quite accustomed to it. Christ, appearing in the form of a man, describes, under the person of the Father, the power, essence, and majesty of God. So then the Father of Christ is the only true God; that is, he is the one God, who formerly promised a Redeemer to the world; but in Christ the oneness and truth of Godhead will be found, because Christ was humbled, in order that he might raise us on high. When we have arrived at this point, then his Divine majesty displays itself; then we perceive that he is wholly in the Father, and that the Father is wholly in him. In short, he who separates Christ from the Divinity of the Father, does not yet acknowledge Him who is the only true God, but rather invents for himself a strange god. This is the reason why we are enjoined to know God, and Jesus Christ whom he hath sent, by whom, as it were, with outstretched hand, he invites us to himself. As to the opinion entertained by some, that it would be unjust, if men were to perish solely on account of their ignorance of God, it arises from their not considering that there is no fountain of life but in God alone, and that all who are alienated from him are deprived of life. Now, if there be no approach to God but by faith, we are forced to conclude, that unbelief keeps us in a state of death. If it be objected, that persons otherwise righteous and innocent are unjustly treated, if they are condemned, the answer is obvious, that nothing right or sincere is found in men, so long as they remain in their natural state. Now, Paul informs us that we are renewed in the image of God by the knowledge of him, ( Colossians 3:10 .) It will be of importance for us now to bring into one view those three articles of faith; first, that the kingdom of Christ brings life, and salvation; secondly, that all do not receive life from him, and it is not the office of Christ to give life to all, but only to the elect whom the Father has committed to his protection; and, thirdly, that this life consists in faith, and Christ bestow, it on those whom he enlightens in the faith of the Gospel. Hence we infer that the gift of illumination and heavenly wisdom is not common to all, but peculiar to the elect. It is unquestionably true that the Gospel is offered to all, but Christ speaks here of that secret and efficacious manner of teaching by which the children of God only are drawn to faith. 4. I have glorified thee. His reason for saying this is, that God had been made known to the world both by the doctrine of Christ, and by his miracles; and the glory of God is, when we know what he is. When he adds, I have finished the work which thou gavest me to do, he means that he has completed the whole course of his calling; for the full time was come when he ought to be received into the heavenly glory Nor does he speak only of the office of teaching, but includes also the other parts of his ministry; for, though the chief part of it still remained to be accomplished, namely, the sacrifice of death, by which he was to take away the iniquities of us all, yet, as the hour of his death was already at hand, he speaks as if he had already endured it. The amount of his request, therefore, is that the Father would put him in possession of the kingdom; since, having completed his course, nothing more remained for him to do, than to display, by the power of the Spirit, the fruit and efficacy of all that he had done on earth by the command of his Father, according to the saying of Paul, He humbled and annihilated himself, [111] by taking the form of a servant. Therefore God hath highly exalted him, and given him a name which is above every name, ( Philippians 2:7 , 10.) 5. The glory which I had with thee. He desires to be glorified with the Father, not that the Father may glorify him secretly, without any witnesses, but that, having been received into heaven, he may give a magnificent display of his greatness and power, that every knee may bow to him, ( Philippians 2:10 .) Consequently, that phrase in the former clause, with the Father, is contrasted with earthly and fading glory, as Paul describes the blessed immortality of Christ, by saying that he died to sin once, but now he liveth to God, ( Romans 6:10 .) The glory which I had with thee before the world was. He now declares that he desires nothing that does not strictly belong to him, but only that he may appear in the flesh, such as he was before the creation of the world; or, to speak more plainly, that the Divine majesty, which he had always possessed, may now be illustriously displayed in the person of the Mediator, and in the human flesh with which he was clothed. This is a remarkable passage, which teaches us that Christ is not a God who has been newly contrived, or who has existed only for a time; for if his glory was eternal, himself also has always been. Besides, a manifest distinction between the person of Christ and the person of the rather is here expressed; from which we infer, that he is not only the eternal God, but also that he is the eternal Word of God, begotten by the rather before all ages.

Geneva Bible Notes (1599)
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.
John Trapp (1647)
And this is life eternal, that they might know thee the only true God, and Jesus Christ, whom thou hast sent. That they may know thee — To know God in the face of Christ is heaven beforehand; Qui non habet Christum in horoscopo, non habet Deum in medio caeli. (Bucholcer.) "By his knowledge shall my righteous servant justify many," saith God concerning Christ, Isaiah 53:11 , that is, by faith; which enfolds assent of the judgment, consent of the will, and affiance or assurance of the heart. Papists place faith in the will only, and exclude knowledge. Nay, Bellarmine affirmeth that faith may be better defined by ignorance (that mother of devotion) than by knowledge. They dig out men’s eyes (as they dealt by Samson) and then make sport with them; they confine faith to the will, that they may do what they will with the understanding and the heart; as the friars send men on pilgrimage, that they may lie with their wives the while.
Matthew Poole (1685)
Those who deny the Divine nature of Christ, think they have a mighty argument from, this text, where Christ, (as they say), speaking to his Father, calleth him the only true God. But divines answer, that the term only, or alone, is not to be applied to thee, but to the term God; and the sense this: To know thee to be that God which is the only true God: and this appeareth from 1Jo 5:20 , where Christ is said to be the true God, which he could not be if the Father were the only true God, considered as another from the Son. The term only, or alone, is not exclusive of the other two Persons in the Trinity, but only of idols, the gods of the heathen, which are no gods; so 1 Timothy 6:15 ,16 , and many other Scriptures: so Matthew 11:27 , where it is said, that none knoweth the Son, but the Father; neither knoweth any the Father, save the Son; where the negative doth not exclude the Holy Spirit. Besides, the term alone is in Scripture observed not always to exclude all others, as Mark 6:47 . Our Saviour saith, it is life eternal to know him who is the only true God, that is, it is the way to eternal life, which is an ordinary figure used in holy writ. He adds, and Jesus Christ, whom thou hast sent; by which he lets us know, that the Father cannot be savingly known, but in and by the Son. Knowing, in this verse, signifies not the mere comprehending of God and of Christ in men’s notions; but the receiving Christ, believing in him, loving and obeying him, &c.
John Gill (1748)
And this is life eternal,.... That is, the beginning and pledge of it, the way unto it, and means of it, and what will certainly issue in it: that they might know thee, the only true God, and Jesus Christ, whom thou hast sent. The knowledge of God here spoken of, is not the knowledge of him by the light of nature, and works of creation; for a man may know God in this sense, and not know him in Christ, nor anything of Christ; yea, may know God and profess him in words, and in works deny him, as the Heathens did; nor is eternal life known hereby, nor connected with it: nor is it such a knowledge of God as is to be obtained by the law of Moses, in which God is represented as a righteous and incensed Being; nor is there in it any discovery of God, as a God of love, grace, and mercy in Christ; nor any revelation of a Mediator, Saviour and Redeemer; nor can it either show, or give to persons eternal life; and yet what is here said of the knowledge of God and Christ, the Jews say of the law (d), "one man said to his friend, let us dash them against that wall and kill them, because they have left , "eternal life"; (the gloss upon it is, "the law";) and employ themselves in a temporary life, the gloss says of this world, which is merchandise.'' More truly does Philo the Jew say (e), that "fleeing to the Divine Being, "is eternal life"; and running front him is death.'' But this is to be understood of an evangelic knowledge of God, as the God and Father of Christ, as the God of all grace, pardoning iniquity, transgression and sin, and of Christ Mediator; not a general, notional, and speculative knowledge; but a practical and experimental one; a knowledge of approbation and appropriation; a fiducial one, whereby a soul believes in Christ, and trusts in his blood, righteousness, and sacrifice for salvation; and which, though imperfect, is progressive. The Arians and Unitarians urge this text, against the true and proper deity of our Lord Jesus, and his equality with the Father, but without success; since the Father is called the only true God, in opposition to the many false gods of the Heathens, but not to the exclusion of the Son or Spirit; for Christ is also styled the one Lord, and only Lord God, but not to the exclusion of the Father; yea the true God and eternal life; was he not, he would never, as here, join himself with the only true God; and besides, eternal life is made to depend as much upon the knowledge of him, as of the Father. The reason of this different mode of expression, is owing to the character of Christ as Mediator, who is said to be sent by the only true God, about the business of man's salvation. Nor is it of any moment what the Jew (f) objects, that Jesus here confesses, that the true God is only one God; nor does he call himself God, only the Messiah sent by God; and that the Apostle Paul also asserts the unity of God, 1 Timothy 1:17 ; and therefore Jesus cannot be God: for Christ and his Father, the only true God, are one; and that he is the one true God with his Father, he tacitly suggests here by joining himself with him; and what the Apostle Paul says of the one and only wise God, may as well be understood of Christ, the Son of God, as of the Father; since all the characters in the text agree with him, and of him he had been speaking in the context. (d) T. Bab. Taanith, fol. 21. 1.((e) De profugis, p. 461. (f) R. Isaac Chizzuk Emuna, par. 2. c. 55. p. 445.
Matthew Henry (1714)
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.
Jamieson-Fausset-Brown
3. this is—that. life eternal, that they might—may. know, &c.—This life eternal, then, is not mere conscious and unending existence, but a life of acquaintance with God in Christ (Job 22:21). thee, the only true God—the sole personal living God; in glorious contrast equally with heathen polytheism, philosophic naturalism, and mystic pantheism. and Jesus Christ whom thou hast sent—This is the only place where our Lord gives Himself this compound name, afterwards so current in apostolic preaching and writing. 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].
Barnes (1832)
This is life eternal - This is the source of eternal life; or it is in this manner that it is to be obtained. The knowledge of God and of his Son Jesus Christ is itself a source of unspeakable and eternal joy. Compare John 11:25 ; John 6:63 ; John 12:50 . Might know thee - The word "know" here, as in other places, expresses more than a mere speculative acquaintance with the character and perfections of God. "It includes all the impressions on the mind and life which a just view of God and of the Saviour is fitted to produce." It includes, of course, love, reverence, obedience, honor, gratitude, supreme affection. "To know God as he is" is to know and regard him as a lawgiver, a sovereign, a parent, a friend. It is to yield the whole soul to him, and strive to obey his law. The only true God - The only God, in opposition to all false gods. What is said here is in opposition to idols, not to Jesus himself, who, in 1 John 5:20 , is called "the true God and eternal life." And Jesus Christ - To know Jesus Christ is to have a practical impression of him as he is - that is, to suffer his character and work to make their due impression on the heart and life. Simply to have heard that there is a Saviour is not to know it. To have been taught in childhood and trained up in the belief of it is not to know it. To know him is to have a just, practical view of him in all his perfections as God and man; as a mediator; as a prophet, a priest, and a king. It is to feel our need of such a Saviour, to see that we are sinners, and to yield the whole soul to him, knowing that he is a Saviour suited to our needs, and that in his hands our souls are safe. Compare Ephesians 3:19 ; Titus 1:16 ; Philippians 3:10 ; 1 John 5:20 . In this verse is contained the sum and essence of the Christian religion, as it is distinguished from all the schemes of idolatry and philosophy, and all the false plans on which men have sought to obtain eternal life. The Gentiles worshipped many gods; the Christian worships one - the living and the true God; the Jew, the Deist, the Muslim, the Socinian, profess to acknowledge one God, without any atoning sacrifice and Mediator; the true Christian approaches him through the great Mediator, equal with the Father, who for us became incarnate, and died that he might reconcile us to God.
