1 John 5:1
Whosoever believeth that Jesus is the Christ is born of God: and every one that loveth him that begat loveth him also that is begotten of him.
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; 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.
