23 This is his commandment, that we should believe in the name of his Son, Jesus Christ, and love one another, even as he commanded.

And this is his commandment He again accommodates a general truth to his own purpose. The meaning is, that such is the discord between us and God, that we are kept off from an access to him, except we are united by love to one another. At the same time he does not here commend love alone, as before, but joins it as the companion and attendant of faith. The Sophists by their glosses distort these words, as though liberty to pray were obtained by us, partly by faith and partly by works. As John requires us to keep God's commandments that we may pray aright, and afterwards teaches us that this keeping refers to faith and love, they conclude, that from these two things ought we to derive confidence in prayer. But I have already several times reminded you, that the subject here is not how or by what means men may prepare themselves so that they may have confidence to pray to God, for he speaks not here of the cause of ills or of any worthiness. John only shews, that God favors none with the honor and privilege of intercourse with himself but his own children, even those who have been regenerated by his Spirit. The import, then, of what is said is, Where the fear and love of God do not prevail, it cannot be that God will hear prayer. But if it be our purpose to obey his commandments, let us see what he commands. He does not, however, separate faith from love; but he requires both together from us. And this is the reason why he uses the word commandment in the singular number. But this is a remarkable passage; for he defines briefly as well as lucidly in what the whole perfection of a holy life consists. There is then no reason that we should allege any difficulty, since God does by no means lead us about through long labyrinths, but simply and shortly sets before us what is right and what he approves. Besides, in this brevity there is no obscurity, for he shews to us clearly the beginning and the end of a life rightly formed. But that a mention is here only made of brotherly love, while the love of God is omitted, the reason is, as we have elsewhere said, that as brotherly love flows from the love of God, so it is a sure and real evidence of it. On the name of his Son The name refers to preaching; and this connection deserves to be noticed, for few understand what it is to believe on Christ; but from this mode of speaking, we may easily conclude that the only right faith is that which embraces Christ as he is set forth in the Gospel. Hence also it is, that there is no faith without teaching, as Paul also shews to us in Romans 10:14. We must at the same time observe, that the Apostle includes faith in the knowledge of Christ; for he is the living image of the Father, and in him are laid up all the treasures of wisdom and knowledge. As soon, then, as we turn aside from him, we cannot do anything else but wander in error.
And this is his commandment - His commandment, by way of eminence; the leading, principal thing which he enjoins on us; the commandment which lies at the foundation of all true obedience.
That we should believe on the name of his Son Jesus Christ - See the notes at Mark 16:16. Compare John 16:1; Acts 16:31.
And love one another - This follows from the other, and hence they are mentioned as together constituting his commandment. Notes, John 13:35.
That we should believe on the name of his Son - We are commanded to believe on Christ, that for the sake of his passion and death we may be justified from all things from which we could not be justified by the law of Moses; and being through him redeemed from the guilt of sin, restored to the Divine favor, and made partakers of the Holy Ghost, we are enabled to love one another as he gave us commandment; for without a renewal of the heart, love to God and man is impossible, and this renewal comes by Christ Jesus.
And this is his commandment,.... Having mentioned the keeping of the commandments of God, the apostle proceeds to show what they are; that they are faith in Christ, and love to one another; which two are reduced to one, because they are inseparable; where the one is, the other is; faith works by love.
That we should believe on the name of his Son Jesus Christ; Christ is the object of faith, and he is no, as he is Jesus, a Saviour; faith deals with him as such, and will have no other Saviour but he: and now to believe in him, is not merely to believe that he is the Son of God, the true Messiah, the Saviour of the world, that he is come in the flesh, has suffered, and died, and rose again from the dead, is ascended into heaven, and is set down at the right hand of God, makes intercession for his people, and will come again to judge the quick and dead; but it is to go forth in special and spiritual acts upon him, such as looking at him, coming to him, venturing on him, trusting in him for life and salvation, committing all into his hands, and expecting all from him. And this is called a "commandment", and comes under the notion of one; not that it is properly a law, or belongs to the law; for faith in Christ Jesus is a fruit of electing grace, and a blessing of the covenant of grace; it is the free gift of God, and the operation of his Spirit, and is peculiar to the elect of God, and sheep of Christ; and so cannot belong to the law of works; but, as the Hebrew words, and both signify any doctrine, and instruction in general; see Psalm 19:7; so the word here used designs an evangelical doctrine, a divine instruction of our Lord Jesus Christ, in the Gospel, which declares that he that believes in Christ shall be saved; and so the word is used for a doctrine in this epistle, 1-John 2:7; and that of the next command or doctrine, which follows,
and love one another as he gave us commandment; that is, as Christ taught and instructed his disciples, John 13:34.
Summing up of God's commandments under the Gospel dispensation in one commandment.
this is his commandment--singular: for faith and love are not separate commandments, but are indissolubly united. We cannot truly love one another without faith in Christ, nor can we truly believe in Him without love.
believe--once for all; Greek aorist.
on the name of his Son--on all that is revealed in the Gospel concerning Him, and on Himself in respect to His person, offices, and atoning work.
as he--as Jesus gave us commandment.
And this is his commandment. The commandments may be summed up in one, with two parts, viz.: Faith in Jesus Christ, and love of the brethren.
He that keepeth his commandments. By keeping them we dwell in him and he in us. See John 14:23.
We know that he abideth in us, by the Spirit. The Spirit that dwells in us is manifest by its fruits. If we bear the fruits of the Spirit in our lives it is proof that Christ dwells in us. If we are led by the Spirit we are the sons of God (Romans 8:14).
And this is his commandment - All his commandments in one word. That we should believe and love - in the manner and degree which he hath taught. This is the greatest and most important command that ever issued from the throne of glory. If this be neglected, no other can be kept: if this be observed, all others are easy.
