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.

This is life eternal - The salvation purchased by Christ, and given to them who believe, is called life:

1. Because the life of man was forfeited to Divine justice; and the sacrifice of Christ redeemed him from that death to which he was exposed.

2. Because the souls of men were dead in trespasses and sins; and Christ quickens them by his word and Spirit.

3. Because men who are not saved by the grace of Christ do not live, they only exist, no good purpose of life being answered by them. But when they receive this salvation they live - answer all the Divine purposes, are happy in themselves, useful to each other, and bring glory to God.

4. It is called eternal life to show that it reaches beyond the limits of time, and that it necessarily implies -

1. The immortality of the soul;

2. the resurrection of the body; and

3. that it is never to end, hence called αιωνιος ζωη, a life ever living; from αει, always, and ων, being or existence. And indeed no words can more forcibly convey the idea of eternity than these. It is called ἡ αιωνιος ζωη, That eternal life, by way of eminence. There may be an eternal existence without blessedness; but this is that eternal life with which infinite happiness is inseparably connected.

The only true God - The way to attain this eternal life is to acknowledge, worship, and obey, the one only true God, and to accept as teacher, sacrifice, and Savior, the Lord Jesus, the one and only true Messiah. Bishop Pearce's remark here is well worthy the reader's attention: -

"What is said here of the only true God seems said in opposition to the gods whom the heathens worshipped; not in opposition to Jesus Christ himself, who is called the true God by John, in 1 John 5:20."

The words in this verse have been variously translated:

1. That they might acknowledge thee, and Jesus Christ whom thou hast sent, to be the only true God.

2. That they might acknowledge thee, the only true God, and Jesus, whom thou hast sent, to be the Christ or Messiah.

3. That they might acknowledge thee to be the only true God, and Jesus Christ to be him whom thou hast sent. And all these translations the original will bear.

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.

Life eternal

With the article: the life eternal. Defining the words in the previous verse. The life eternal (of which I spoke) is this.

That (ἵνα)

Expressing the aim.

Might know (γινώσκωσι)

Might recognize or perceive. This is striking, that eternal life consists in knowledge, or rather the pursuit of knowledge, since the present tense marks a continuance, a progressive perception of God in Christ. That they might learn to know. Compare John 17:23; John 10:38; 1 John 5:20; 1 John 4:7, 1 John 4:8.

"I say, the acknowledgment of God in Christ

Accepted by thy reason, solves for thee

All questions in the earth and out of it,

And has so far advanced thee to be wise.

Wouldst thou improve this to reprove the proved?

In life's mere minute, with power to use that proof,

Leave knowledge and revert to how it sprung?

Thou hast it; use it, and forthwith, or die.

continued...

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.

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.

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.

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].

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.
