20 We know that the Son of God has come, and has given us an understanding, that we know him who is true, and we are in him who is true, in his Son Jesus Christ. This is the true God, and eternal life.

And we know that the Son of God is come As the children of God are assailed on every side, he, as we have said, encourages and exhorts them to persevere in resisting their enemies, and for this reason, because they fight under the banner of God, and certainly know that they are ruled by his Spirit; but he now reminds them where this knowledge is especially to be found. He then says that God has been so made known to us, that now there is no reason for doubting. The Apostle does not without reason dwell on this point; for except our faith is really founded on God, we shall never stand firm in the contest. For this purpose the Apostle shews that we have obtained through Christ a sure knowledge of the true God, so that we may not fluctuate in uncertainty. By true God he does not mean one who tells the truth, but him who is really God; and he so calls him to distinguishing him from all idols. Thus true is in opposition to what is fictitious; for it is alethinos, and not alethes A similar passage is in John "This is eternal life, to know thee, the only true God, and him whom thou hast sent, Jesus Christ." (John 17:3) And he justly ascribes to Christ this office of illuminating our minds as to the knowledge of God. For, as he is the only true image of the invisible God, as he is the only interpreter of the Father, as he is the only guide of life, yea, as he is the life and light of the world and the truth, as soon as we depart from him, we necessarily become vain in our own devices. And Christ is said to have given us an understanding, not only because he shews us in the gospel what sort of being is the true God, and also illuminates us by his Spirit; but because in Christ himself we have God manifested in the flesh, as Paul says, since in him dwells all the fullness of the Deity, and are hid all the treasures of knowledge and wisdom. (Colossians 2:9.) Thus it is that the face of God in a manner appears to us in Christ; not that there was no knowledge, or a doubtful knowledge of God, before the coming of Christ,, but that now he manifests himself more fully and more clearly. And this is what Paul says in 2-Corinthians 4:6, that God, who formerly commanded light to shine out of darkness at the creation of the world, hath now shone in our hearts through the brightness of the knowledge of his glory in the face of Christ. And it must be observed, that this gift is peculiar to the elect. Christ, indeed, kindles for all indiscriminately the torch of his gospel; but all have not the eyes of their minds opened to see it, but on the contrary Satan spreads the veil of blindness over many. Then the Apostle means the light which Christ kindles within in the hearts of his people, and which when once kindled, is never extinguished, though in some it may for a time be smothered. We are in him that is true By these words he reminds us how efficacious is that knowledge which he mentions, even because by it we are united to Christ; and become one with God; for it has a living root, fixed in the heart, by which it comes that God lives in us and we in him. As he says, without a copulative, that: we are in him that is true, in his Son, he seems to express the manner of our union with God, as though he had said, that we are in God through Christ. [1] This is the true God Though the Arians have attempted to elude this passage, and some agree with them at this day, yet we have here a remarkable testimony to the divinity of Christ. The Arians apply this passage to the Father, as though the Apostle should again repeat that he is the true God. But nothing could be more frigid than such a repetition. It has already twice testified that the true God is he who has been made known to us in Christ, why should he again add, This is the true God? It applies, indeed, most suitably to Christ; for after having taught us that Christ is the guide by whose hand we are led to God, he now, by way of amplifying, affirms that Christ is that God, lest we should think that we are to seek further; and he confirms this view by what is added, and eternal life. It is doubtless the same that is spoken of, as being the true God and eternal life. I pass by this, that the relative houtos usually refers to the last person. I say, then, that Christ is properly called eternal life; and that this mode of speaking perpetually occurs in John, no one can deny. The meaning is, that when we have Christ, we enjoy the true and eternal God, for nowhere else is he to be sought; and, secondly, that we become thus partakers of eternal life, because it is offered to us in Christ though hid in the Father. The origin of life is, indeed, the Father; but the fountain from which we are to draw it, is Christ.
1 - It is rendered by some, "through his Son Jesus Christ." Our version, "even in his Son Jesus Christ," seems not to be right, as it makes "him that is true," to be the Son, while the reference is to God, as in the previous clause. The true meaning would be thus conveyed, "And we are in the true God, being in his Son Jesus Christ;" for to be in Christ, is to be in God. Three MSS., the Vulgate, and several of the Fathers, read thus, "and we are in his true Son Jesus Christ". -- Ed.
And we know that the Son of God is come - We know this by the evidence that John had referred to in this Epistle, 1-John 1:1-4; 1-John 5:6-8.
And hath given us an understanding - Not an "understanding" considered as a faculty of the mind, for religion gives us no new faculties; but he has so instructed us that we do understand the great truths referred to. Compare the notes at Luke 24:45. All the correct knowledge which we have of God and his government, is to be traced directly or indirectly to the great Prophet whom God has sent into the world, John 1:4, John 1:18; John 8:12; John 9:5; Hebrews 1:1-3; Matthew 11:27.
That we may know him that is true - That is, the true God. See the notes at John 17:3.
And we are in him that is true - That is, we are united to him; we belong to him; we are his friends. This idea is often expressed in the Scriptures by being "in him." It denotes a most intimate union, as if we were one with him - or were a part of him - as the branch is in the vine, John 15:4, John 15:6. The Greek construction is the same as that applied to "the wicked one," 1-John 5:19, (ἐν τῷ ἀληθινᾧ en tō alēthinō.)
This is the true God - o There has been much difference of opinion in regard to this important passage; whether it refers to the Lord Jesus Christ, the immediate antecedent, or to a more remote antecedent - referring to God, as such. The question is of importance in its bearing on the doctrine of the divinity of the Saviour; for if it refers to him, it furnishes an unequivocal declaration that he is divine. The question is, whether John "meant" that it should be referred to him? Without going into an extended examination of the passage, the following considerations seem to me to make it morally certain that by the phrase "this is the true God," etc., he did refer to the Lord Jesus Christ.
(1) the grammatical construction favors it. Christ is the immediate antecedent of the pronoun "this" - οὗτος houtos. This would be regarded as the obvious and certain construction so far as the grammar is concerned, unless there were something in the thing affirmed which led us to seek some more remote and less obvious antecedent. No doubt would have been ever entertained on this point, if it had not been for the reluctance to admit that the Lord Jesus is the true God. If the assertion had been that "this is the true Messiah;" or that "this is the Son of God;" or that "this is he who was born of the Virgin Mary," there would have been no difficulty in the construction. I admit that his argument is not absolutely decisive; for cases do occur where a pronoun refers, not to the immediate antecedent, but to one more remote; but cases of that kind depend on the ground of necessity, and can be applied only when it would be a clear violation of the sense of the author to refer it to the immediate antecedent.
(2) this construction seems to be demanded by the adjunct which John has assigned to the phrase "the true God" - "eternal life." This is an expression which John would be likely to apply to the Lord Jesus, considered as "life," and the "source of life," and not to God as such. "How familiar is this language with John, as applied to Christ! "In him (i. e. Christ) was life, and the life was the light of people - giving life to the world - the bread of life - my words are spirit and life - I am the way, and the truth, and the life. This life (Christ) was manifested, and we have "seen it," and do testify to you, and declare the eternal life which was with the Father, and was manifested to us," 1-John 1:2." - Prof. Stuart's Letters to Dr. Channing, p. 83. There is no instance in the writings of John, in which the appellation life, and "eternal" life is bestowed upon the Father, to designate him as the author of spiritual and eternal life; and as this occurs so frequently in John's writings as applied to Christ, the laws of exegesis require that both the phrase "the true God," and "eternal life," should be applied to him.
(3) if it refers to God as such, or to the word "true" - τὸν ἀληθινόν (Θεὸν) ton alēthinon (Theon) it would be mere tautology, or a mere truism. The rendering would then be, "That we may know the true God, and we are in the true God: this is the true God, and eternal life." Can we believe that an inspired man would affirm gravely, and with so much solemnity, and as if it were a truth of so much magnitude, that the true God is the true God?
(4) this interpretation accords with what we are sure John would affirm respecting the Lord Jesus Christ. Can there be any doubt that he who said, "In the beginning was the Word, and the Word was with God, and the Word was God;" that he who said, "all things were made by him, and without him was not anything made that was made;" that he who recorded the declaration of the Saviour, "I and my Father are one," and the declaration of Thomas, "my Lord and my God," would apply to him the appellation "the true God!"
(5) if John did not mean to affirm this, he has made use of an expression which was liable to be misunderstood, and which, as facts have shown, would be misconstrued by the great portion of those who might read what he had written; and, moreover, an expression that would lead to the very sin against which he endeavors to guard in the next verse - the sin of substituting a creature in the place of God, and rendering to another the honor due to him. The language which he uses is just such as, according to its natural interpretation, would lead people to worship one as the true God who is not the true God, unless the Lord Jesus be divine. For these reasons, it seems to me that the fair interpretation of this passage demands that it should be understood as referring to the Lord Jesus Christ. If so, it is a direct assertion of his divinity, for there could be no higher proof of it than to affirm that he is the true God.
And eternal life - Having "life in himself," John 5:26, and the source and fountain of life to the soul. No more frequent appellation, perhaps, is given to the Saviour by John, than that he is life, and the source of life. Compare John 1:4; John 5:26, John 5:40; John 10:10; John 6:33, John 6:35, John 6:48, John 6:51, John 6:53, John 6:63; John 11:25; John 14:6; John 20:31; 1-John 1:1-2; 1-John 5:12.
We know that the Son of God is come - In the flesh, and has made his soul an offering for sin; and hath given us an understanding - a more eminent degree of light than we ever enjoyed before; for as he lay in the bosom of the Father, he hath declared him unto us; and he hath besides given us a spiritual understanding, that we may know him who is true, even the True God, and get eternal life from him through his Son, In whom we are by faith, as the branches in the vine, deriving all our knowledge, light, life, love, and fruitfulness from him. And it is through this revelation of Jesus that we know the ever blessed and glorious Trinity; and the Trinity, Father, Word, and Holy Ghost, in the eternal, undivided unity of the ineffable Godhead.
And we know that the Son of God is come, and hath given us an understanding, that we may know him that is true, and we are in him that is true, [even] in his Son Jesus Christ. This is the true (m) God, and eternal life.
(m) The divinity of Christ is most clearly proved by this passage.
And we know that the Son of God is come,.... That the second Person in the Godhead, who is equal to the Father, and of the same nature with him, is come from the Father, from heaven into this world, not by local motion, but by assumption of nature; that he is come in the flesh, or is become incarnate, in order to work out salvation for his people, by his obedience, sufferings, and death; and this John and others knew, for they had personal knowledge of him, and converse with him; they saw him with their eyes, heard him, and handled him: he dwelt among them, preached to them, wrought miracles before them, which proved him to be what he was; and it may be known that the Messiah must become, since Daniel's weeks, which fixes the time of his coming, are long ago up; the sceptre is departed from Judah, and the second temple is destroyed, neither of which were to be till the Messiah came; and that Jesus of Nazareth is he who is come may be known by the characters of him, and the works done by him:
and hath given us an understanding; not a new faculty of the understanding but new light into it; a knowledge of spiritual things of himself, and of God in him, and of the truths of the Gospel, and of all divine and heavenly things; for he, the Son of God, is come a light into the world, and gives spiritual light to men:
that we may know him that is true; or "the true God", as the Alexandrian copy and some others, and the Vulgate Latin, Arabic, and Ethiopic versions read; that is, God the Father, who is the true God, in opposition to the false gods of the Heathens, though not to the exclusion of the Son and Spirit; and the spiritual knowledge of him as the Father of Christ, and as a covenant God and Father in him, is only given to men by Christ, and this is life eternal; see Matthew 11:27;
and we are in him that is true, even in his Son Jesus Christ; the words "Jesus Christ" are left out in the Alexandrian copy, and in the Vulgate Latin version; however, certain it is, that Jesus Christ is meant by his Son, who is the Son of the true and living God, and is himself "true"; not only true God, as hereafter asserted, but true man, having a true body and a reasonable soul, and was true and faithful in the discharge of his offices, as prophet, priest, and King; he faithfully declared the whole will of God, and taught the way of God in truth; he was faithful to him that appointed him, by securing his glory when he made reconciliation for the sins of the people; and all the administrations of his kingly office are just and true; yea, he is truth itself, the substance of all the types, in whom all the promises are yea and amen, and who has all the truths of the Gospel and treasures of wisdom in him; now his people are in him; they were secretly in him before the world was, being loved by him, chosen in him, put into his hands, preserved in him, and represented by him; and openly, at conversion, when they are anew created in him, brought to believe in him, and live upon him, and he lives in them, and they are in him as branches in the vine; and this is known by his Spirit being given them, by the communication of his grace unto them, and by the communion they have with him.
This is the true God and eternal life; that is, the Son of God, who is the immediate antecedent to the relative "this"; he is the true God, with his Father and the Spirit, in distinction from all false, fictitious, or nominal deities; and such as are only by office, or in an improper and figurative sense: Christ is truly and really God, as appears from all the perfections of deity, the fulness of the Godhead being in him; from the divine works of creation and providence being ascribed to him; and from the divine worship that is given him; as well as from the names and titles he goes by, and particularly that of Jehovah, which is incommunicable to a creature; and he is called "eternal life", because it is in him; and he is the giver of it to his people; and that itself will chiefly consist in the enjoyment and vision of him, and in conformity to him.
Summary of our Christian privileges.
is come--is present, having come. "HE IS HERE--all is full of Him--His incarnation, work, and abiding presence, is to us a living fact" [ALFORD].
given us an understanding--Christ's, office is to give the inner spiritual understanding to discern the things of God.
that we may know--Some oldest manuscripts read, "(so) that we know."
him that is true--God, as opposed to every kind of idol or false god (1-John 5:21). Jesus, by virtue of His oneness with God, is also "He that is true" (Revelation 3:7).
even--"we are in the true" God, by virtue of being "in His Son Jesus Christ."
This is the true God--"This Jesus Christ (the last-named Person) is the true God" (identifying Him thus with the Father in His attribute, "the only true God," John 17:3, primarily attributed to the Father).
and eternal life--predicated of the Son of God; ALFORD wrongly says, He was the life, but not eternal life. The Father is indeed eternal life as its source, but the Son also is that eternal life manifested, as the very passage (1-John 1:2) which ALFORD quotes, proves against him. Compare also 1-John 5:11, 1-John 5:13. Plainly it is as the Mediator of ETERNAL LIFE to us that Christ is here contemplated. The Greek is, "The true God and eternal life is this" Jesus Christ, that is, In believing in Him we believe in the true God, and have eternal life. The Son is called "He that is TRUE," Revelation 3:7, as here. This naturally prepares the way for warning against false gods (1-John 5:21). Jesus Christ is the only "express image of God's person" which is sanctioned, the only true visible manifestation of God. All other representations of God are forbidden as idols. Thus the Epistle closes as it began (1-John 1:1-2).
And we know - By all these infallible proofs. That the Son of God is come - Into the world. And he hath given us a spiritual understanding, that we may know him, the true one - "The faithful and true witness." And we are in the true one - As branches in the vine, even in Jesus Christ, the eternal Son of God. This Jesus is the only living and true God, together with the father and the Spirit, and the original fountain of eternal life. So the beginning and the end of the epistle agree.
