Being born again Here is another reason for an exhortation, -- that since they were new men and born again of God, it behoved them to form a life worthy of God and of their spiritual regeneration. And this seems to be connected with a verse in the next chapter respecting the milk of the word, which they were to seek, that their way of living might correspond with their birth. It may, however, be extended wider, so as to be connected also with what has gone before; for Peter collected together those things which may lead us to an upright and a holy life. The object, then, of Peter was to teach us that we cannot be Christians without regeneration; for the Gospel is not preached, that it may be only heard by us, but that it may, as a seed of immortal life, altogether reform our hearts. [1] Moreover, the corruptible seed is set in opposition to God's word, in order that the faithful might know that they ought to renounce their former nature, and that it might be more evident how much is the difference between the children of Adam who are born only into the world, and the children of God who are renewed into a heavenly life. But as the construction of the Greek text is doubtful, we may read, "the living word of God," as well as, "the word of the living God." As, however, the latter reading is less forced, I prefer it; though it must be observed, that the term is applied to God owing to the character of the passage. For, as in Hebrews 4:12, because God sees all things, and nothing is hid from him, the apostle argues that the word of God penetrates into the inmost marrow, so as to discern thoughts and feelings; so, when Peter in this place calls him the living God, who abides for ever, he refers to the word, in which the perpetuity of God shines forth as in a living mirror.

Footnotes

1 - Most commentators, like Calvin, represent the seed as the word; but the construction does not admit this; the words are, "Having been begotten from a seed, not corruptible, but incorruptible, through the living word of God, and for-ever abiding." The "seed" denotes evidently the vital principle of grace, the new nature, the restored image of God; it is the same with what John means when he says, "His seed (that is, of God) remaineth in him." (1 John 3:9.) Then "the word" is set forth as the means or instrument by which this seed is implanted. The "living" here does not mean life-giving, as some interpret it, but stands opposed to what ceases to be valid: and "for-ever abiding" more fully expresses its meaning. The metaphor in the parable of the sower is quite different: the word there is compared to a seed sown on bad or good ground; but here the turning of a bad into a good ground is the subject; and in this process the word is employed as an instrument. -- Ed.

Being born again - See the notes at John 3:3.
Not of corruptible seed - "Not by virtue of any descent from human parents" - Doddridge. The result of such a birth, or of being begotten in this way - for so the word rendered "born again" more properly signifies - is only corruption and decay. We are begotten only to die. There is no permanent, enduring life produced by that. It is in this sense that this is spoken of as, "corruptible seed," because it results in decay and death. The word here rendered "seed" - σπορά spora - occurs nowhere else in the New Testament.
But of incorruptible - By truth, communicating a living principle to the soul which can never decay. Compare 1-John 3:9; "His seed remaineth in him; and he cannot sin, because he is born of God."
By the word of God - See the note at James 1:18; "Of his own will begat he us with the word of truth, that we should be a kind of first-fruits of his creatures." Compare the notes at John 1:13. It is the uniform doctrine of the Scriptures that divine truth is made the instrument of quickening the soul into spiritual life.
Which liveth and abideth forever - This expression may either refer to God, as living forever, or to the word of God, as being forever true. Critics are about equally divided in the interpretation. The Greek will bear either construction. Most of the recent critics incline to the latter opinion - that it refers to the word of God, or to his doctrine. So Rosenmuller, Doddridge, Bloomfield, Wolf, Macknight, Clarke. It seems to me, however, that the more natural construction of the Greek is to refer it to God, as ever-living or enduring; and this interpretation agrees well with the connection. The idea then is, that as God is ever-living, that which is produced directly by him in the human soul, by the instrumentality of truth, may be expected also to endure forever. It will not be like the offspring of human parents, themselves mortal, liable to early and certain decay, but may be expected to be as enduring as its ever-living Creator.

Being born again - For being born of Abraham's seed will not avail to the entering of the kingdom of heaven.
Not of corruptible seed - By no human generation, or earthly means; but of incorruptible - a Divine and heavenly principle which is not liable to decay, nor to be affected by the changes and chances to which all sublunary things are exposed.
By the word of God - Δια λογου ζωντος Θεου· By the doctrine of the living God, which remaineth for ever; which doctrine shall never change, any more than the source shall whence it proceeds.

Being born again,.... As they were of God, according to his abundant mercy, by the resurrection of Christ, to a lively hope of a glorious inheritance; as in 1-Peter 1:3 and therefore seeing they were brethren in a spiritual relation, they ought to love as brethren; being children of the same Father, belonging to the same family and household, having the same spirit, and the same nature and disposition, and being members one of another, and heirs of the same grace and glory; and not only so, but were taught of God their Father, in regeneration, to love one another: it became them highly, therefore, to exercise that grace, and particularly since they were born,
not of corruptible seed, but of incorruptible; referring not to seed cast into the earth, which first corrupts and dies, and then is quickened, and rises, and brings forth fruit; but to human seed, and which the Jews call , "the filthy drop" (k); which is in itself corrupt, and is corrupted, and whereby the corruption of human nature is propagated; for whatsoever is born of the flesh is carnal and corrupt; and so the apostle has reference to the first birth, or natural generation of men, in which they are polluted and depraved, and confirms what the evangelist says, John 1:13 that regenerate persons are not "born of blood"; or become new creatures, and holy men, by their natural descent, or first birth, be it from whom it will; for all men are of one blood originally, and that is tainted with sin; nor by the will of fallen creatures, of corruptible men, themselves or others; but of water, and of the Spirit, of the grace of the Spirit of God, which is seed pure and incorruptible, having no mixture or taint of sin, nor any degree of pollution in it, and which remains so; nor can it be corrupted by all the wickedness there is in man's heart; nor by all the pollutions of the world, or temptations of Satan; and this seed is conveyed into the heart by the Spirit of God, in regeneration, and it contains all grace in it,
by the Word of God, which liveth and abideth for ever; for the incorruptible seed, and the ever living and abiding word, are two distinct things; though interpreters generally confound them: and by "the word of God" is either meant the essential Word, the Lord Jesus Christ; who is concerned in regeneration as well as the Father and the Spirit; by whose resurrection, and in consequence of it, the elect of God are begotten again; and who, as the Word, is able to build up all the sanctified ones, and give them the inheritance they are born heirs unto: or the Gospel, the word of truth, which is made use of as a means of begetting souls again; and the rather, since it seems to be so interpreted, 1-Peter 1:25 the phrases, "which liveth and abideth forever", may be either read in connection only with "God", and as descriptive of him, who is the living God, is from everlasting to everlasting, in distinction from idols; and here added, to show that he can give power and efficacy to his word, to regenerate and quicken, and will continue to preserve and make it useful to all his saving purposes; so Jarchi explains the passage in Isaiah 40:8 after referred to, "the word of our God shall stand for ever",
"because he lives and abides, and it is in his power to confirm it therefore it follows, "O Zion, that bringeth good tidings, get thee up into the high mountain"; for because he lives forever, this promise is published.
Or else with the word of God, and is true both of Christ, and of the Gospel. Christ is the Word which lives; in him, as such, is life; he has life in himself as God, as man, and as Mediator; and is the author of life, natural, spiritual, and, eternal; and abides for ever in his person, without any change; and in his offices and grace, and righteousness; he abides a priest continually, has an unchangeable priesthood, and ever lives to make intercession, and of his kingdom there is no end: the same is said of the "Memra", or Word of God, in the Chaldee paraphrase on Hosea 11:9 "I am God", "my word abideth for ever": compare John 12:34. The Gospel also may be said to live, in opposition to the law, which is the killing letter; and because it points out the way of life and salvation to sinners; and is a means of quickening dead sinners, and of ingenerating that faith by which men live on Christ; and of revealing to them that righteousness which is unto justification of life; and of supporting and maintaining spiritual life in them; and of reviving drooping saints; the Syriac version renders it, "the living Word of God": and it remains, and will abide; all its promises, blessings, doctrines, and ordinances, are lasting; it will continue in the world until all the elect of God are gathered in, until the second coming of Christ, and to the end of the world; notwithstanding all the persecutions of men, and cunning, craft of false teachers, and all the ridicule and contempt it is treated with by mockers and scoffers: and will abide in the effects of it, in the hearts of the saints, to all eternity,

Christian brotherhood flows from our new birth of an imperishable seed, the abiding word of God. This is the consideration urged here to lead us to exercise brotherly love. As natural relationship gives rise to natural affection, so spiritual relationship gives rise to spiritual, and therefore abiding love, even as the seed from which it springs is abiding, not transitory as earthly things.
of . . . of . . . by--"The word of God" is not the material of the spiritual new birth, but its mean or medium. By means of the word the man receives the incorruptible seed of the Holy Spirit, and so becomes one "born again": John 3:3-5, "born of water and the Spirit": as there is but one Greek article to the two nouns, the close connection of the sign and the grace, or new birth signified is implied. The word is the remote and anterior instrument; baptism, the proximate and sacramental instrument. The word is the instrument in relation to the individual; baptism, in relation to the Church as a society (James 1:18). We are born again of the Spirit, yet not without the use of means, but by the word of God. The word is not the beggeting principle itself, but only that by which it works: the vehicle of the mysterious germinating power [ALFORD].
which liveth and abideth for ever--It is because the Spirit of God accompanies it that the word carries in it the germ of life. They who are so born again live and abide for ever, in contrast to those who sow to the flesh. "The Gospel bears incorruptible fruits, not dead works, because it is itself incorruptible" [BENGEL]. The word is an eternal divine power. For though the voice or speech vanishes, there still remains the kernel, the truth comprehended in the voice. This sinks into the heart and is living; yea, it is God Himself. So God to Moses, Exodus 4:12, "I will be with thy mouth" [LUTHER]. The life is in God, yet it is communicated to us through the word. "The Gospel shall never cease, though its ministry shall" [CALOVIUS]. The abiding resurrection glory is always connected with our regeneration by the Spirit. Regeneration beginning with renewing man's soul at the resurrection, passes on to the body, then to the whole world of nature.

Which liveth - Is full of divine virtue. And abideth the same for ever.
