John Gill Commentary 1 John 5

Whosoever believeth that Jesus is the Christ
Or the Messiah that was prophesied of old, was long promised to the Jews, and whom they expected; there was a person spoken of in the writings of the Old Testament under this character, (Psalms 2:2) (Daniel 9:25Daniel 9:26) ; and the Jews looked for him; and Jesus of Nazareth is he, as appears by all the characteristics of the Messiah in prophecy being found upon him: this the Jews deny, but is the grand article of faith embraced by the apostles and followers of Jesus, and is of very great importance; he that denies it is a liar, and he that does not believe it shall die in his sins:

The word signifies "anointed", and includes all the offices of the Son of God, to which he was anointed, as prophet, priest, and King; so that to believe him to be the Christ, is to believe him to be that prophet Moses said should come, and who has declared the whole mind and will of his Father; and that he is that priest that should arise after the order of Melchizedek, and make atonement for sin, and intercession for transgressors; and that he is that King whom God has set over his holy hill of Zion, whose laws are to be obeyed, and his commands observed:

but to believe that Jesus is the Christ, or the Messiah, is not barely to give an assent to this truth, or to acknowledge it; so the devils themselves have done, (Luke 4:41) ; and whole nations of men, multitudes of which were never born of God; it is not a mere profession of it before men, or an idle, inoperative faith, which is destitute of love to Christ, and obedience to him;

but whereas his work and business, as the Christ of God, was to bring in an everlasting righteousness, to procure the remission of sin, and to make peace and reconciliation for it, and to obtain eternal salvation; true faith in him as the Messiah is a believing with the heart unto righteousness, or a looking to, and trusting in the righteousness of Christ for justification; and a dealing with his blood for pardon and cleansing, under a sense of guilt and filth; and a laying hold on his atoning sacrifice for the expiation of sin, and peace with God; and a reception of him as the only Saviour and Redeemer, or a dependence on him for life and salvation; and which faith shows itself in love to him, and in a professed subjection to his Gospel, and cheerful submission to his ordinances: and every such person

is born of God ;
is a partaker of the divine nature; has Christ formed, and every grace of the Spirit implanted in him, among which faith in Christ is a considerable one; and such an one in consequence is openly a child and heir of God, wherefore, to be born of God is an instance of great grace, and an high honour and privilege, and of the greatest moment and importance. Regeneration is not owing to the power and will of man, but to the abundant mercy and good will of God, and is an instance of his rich mercy, great love, and free favour, and commands love again:

and everyone that loveth him that begat ;
that is, God the Father, who has begotten them again to a lively hope, according to his abundant mercy and sovereign will; and as he is their Father that has begotten them, they cannot but love him: and such an one

loveth him also that is begotten of him ;
not only Jesus Christ, who by nature is the only begotten of the Father; for those who know God to be their Father by adoption and regeneration, will love Christ, who is the Son of God by nature; see (John 8:42) ; but also every regenerate person, all that are born of God; since they are the children of the same Father with them, belong to the same household and family, and bear the image and likeness of their heavenly Father on them.

By this we know that we are the children God
The Ethiopic version reads, "by this know that we love God"; which, in connection with what follows, makes a tautology, and is a proving "idem per idem": whereas the apostle's view is to show when love to the saints is right; and that is,

love to the brethren may arise from such a cause, as may show that it is not brotherly love, or of a spiritual kind; it may arise from natural relation, or civil friendship, or from a benefit or favour received from them, and from some natural external excellency seen in them; and a man may do acts of love and kindness to the brethren, from what may be called good nature in himself, or with sinister views;

when we love God, and keep his commandments : but true love to the brethren springs from love to God: such who love the saints aright, and by which they may know they do so, they love them because they themselves love God, and in obedience to his command; they love them because they belong to God, and are the objects of his love; because his grace is wrought in them, and his image stamped upon them.

For this is the love of God, that we keep his commandments ,
&c.] Keeping of the commandments of God is an evidence of love to God; this shows that love is not in word and tongue, in profession only, but in deed and in truth; and that such persons have a sense of the love of God upon their souls, under the influence of which they act; and such shall have, and may expect to have, greater manifestations of the love of God unto them:

and his commandments are not grievous ;
heavy, burdensome, and disagreeable; by which are meant, not so much the precepts of the moral law, which through the weakness of the flesh are hard to be kept, and cannot be perfectly fulfilled; though believers indeed, being freed from the rigorous exaction, curse, and condemnation of the law, delight in it after the inward man, and serve it cheerfully with their spirit; and still less the commands of the ceremonial law, which were now abolished, and were grievous to be borne; but rather those of faith in Christ, and love to the saints, (1 John 3:23) ; or it may be the ordinances of the Gospel, baptism, and the Lord's supper, with others, which though disagreeable to unregenerate persons, who do not care to be under the yoke of Christ, however easy and light it is, yet are not heavy and burdensome to regenerate ones; and especially when they have the love of God shed abroad in them, the presence of God with them, communion with Jesus Christ, and a supply of grace and strength from him; then are these ways ways of pleasantness, and paths of peace, and the tabernacles of the Lord are amiable and lovely.

For whatsoever is born of God
Which may be understood either of persons born; of God; or of the new creature, or principle of grace wrought in them, particularly faith hereafter mentioned, which is an heaven born grace, the gift of God, and the operation of his Spirit: this

overcometh the world ;
the god of the world, Satan; the lusts which are in the world; false prophets gone forth into the world; and the wicked men of the world, who by temptations, snares, evil doctrines, threatenings, promises, and ill examples, would avert regenerate ones from observing the commands of God; but such are more than conquerors over all these, through Christ that has loved them:

and this is the victory that overcometh the world, [even] our faith .
The Arabic and Ethiopic versions read, "your faith"; great things, heroic actions, and wonderful victories, are ascribed to faith; see (Hebrews 11:33Hebrews 11:34) ; which must not be understood of the grace itself, as separately considered, but of Christ the object of it, as supported, strengthened, assisted, and animated by him: and then it does wonders, when it is enabled to hold Christ, its shield, in its hand, against every enemy that opposes.

Who is he that overcometh the world
This question carries in it a strong affirmation, that no other person is the conqueror of the world:

but he that believeth that Jesus is the Son of God ?
and this points out what that faith is which obtains the victory over the world; and shows that it is not that trust and confidence which has a man's self, or any mere creature, thing, or person, for its object, but only Jesus Christ, and that as he is the Son of God; and which is not a mere assent to such a proposition, to which devils and unregenerate persons may assent, and do; but it is a seeing of the Son in the glory, fulness, and suitableness of his person, office, and grace; a going to him, being drawn by the Father; and a living upon him as the Son of God, and trusting in him for life, righteousness, and salvation:

and this shows, that the victory over the world is not owing to faith itself, but to its object Christ, who has overcome it, and makes true believers in him more than conquerors over it.
