Of his own will begat he us,.... The apostle instances in one of those good and perfect gifts, regeneration; and he pitches upon a very proper and pertinent one, since this is the first gift of grace God bestows upon his people openly, and in their own persons; and is what involves other gifts, and prepares and makes meet for the gift of eternal life; and therefore may well be reckoned a "good" one, and it is also a "perfect one"; it is done at once; there are no degrees in it, as in sanctification; a man is born again, at once, and is born a perfect new man in all his parts; no one is more regenerated than another, or the same person more regenerated at one time than at another: and this comes from above; it is called a being born from above, in Joh 3:3 as the words there may be rendered; and it comes from God the Father, even the Father of our Lord Jesus, as well as of all lights, 1Pe 1:3 and who in it produces light, in darkness, and whose gifts of grace bestowed along with it are without repentance.
And since this comes from him, he cannot be the author of evil, or tempt unto it. This is a settled and certain point, that all the good that is in men, and is done by them, comes from God; and all the evil that is in them, and done by them, is of themselves.
This act of begetting here ascribed to God, is what is elsewhere called a begetting again, that is, regeneration; it is an implantation of new principles of light and life, grace and holiness, in men; a quickening of them, when dead in trespasses and sins; a forming of Christ in their souls; and a making them partakers of the divine nature; and this is God's act, and not man's.
Earthly parents cannot beget in this sense; nor ministers of the word, not causally, but only instrumentally, as they are instruments and means, which God makes use of; neither the ministry of the word, nor the ordinance of baptism, can of themselves regenerate any; nor can a man beget himself, as not in nature, so not in grace: the nature of the thing shows it, and the impotent case of men proves it: this is God's act, and his only; see Joh 1:13 and the impulsive or moving cause of it is his own will.
God does not regenerate, or beget men by necessity of nature, but of his own free choice; Christ, the Son of God, is begotten of him by necessity of nature, and not as the effect of his will; he is the brightness of his glory necessarily, as the beams and rays of light are necessarily emitted by the sun; but so it is not in regeneration: nor does God regenerate men through any consideration of their will, works, and merits: nor have these any influence at all upon it; but he begets of his own free grace and favour, and of his rich and abundant mercy, and of his sovereign will and pleasure, according to his counsels and purposes of old.
And the means he makes use of, or with which he does it, iswith the word of truth; not Christ, who is the Word, and truth itself; though regeneration is sometimes ascribed to him; and this act of begetting is done by the Father, through the resurrection of Christ from the dead; but the Gospel, which is the word of truth, and truth itself, and contains nothing but truth; and by this souls are begotten and born again; see Eph 1:13 and hence ministers of it are accounted spiritual fathers.
