John 3:7
Marvel not that I said unto thee, Ye must be born again.
Marvel not that I said unto thee,...., For Nicodemus was quite astonished, at this doctrine of the new birth; it was altogether new to him, and unheard of by him; nor could he understand, nor conceive in what manner it could be:
Ye must be born again; in "four" of Beza's copies, it is read "we"; but as Christ was not begotten in a carnal way, or descended not from Adam in the ordinary way of generation, he was not carnal and corrupt, nor in the least tainted with sin; and so stood in no need of regeneration; wherefore such a reading must be rejected. There is a necessity of the regeneration of those, who are the chosen of God, and the redeemed of the Lamb; and of them only can the words be understood; for as for others, they neither can, nor will, nor must be born again: but the people of God "must"; partly because it is the will of God; it is his purpose and resolution, that they shall be regenerated; he has chosen them, through sanctification of the Spirit, unto salvation by Christ: this is the way and method of saving sinners he has fixed upon, namely, not to save them by works of righteousness, but by grace, and according to abundant mercy, through the washing of regeneration, and the renewing of the Holy Ghost: and partly, because of the case and condition of men, which requires it; for whereas the chosen people of God, are predestinated to the adoption of children, and are taken into the family of God, and are heirs to an inheritance, it is necessary they should have a nature, temper, and disposition of mind, suitable to the inheritance they are to enjoy; which they have not in their natural estate, and which is conveyed to them in regeneration: besides, their carnal minds are enmity to God, and it is necessary that they should be friendly to him, which cannot be without regeneration; nor can they, till they are born again, please God, or do those things which are pleasing to him: to which may be added, which Christ has before suggested, and which shows the necessity of it, that without it, no man can either see, or enter into the kingdom of God. To take off the surprise of Nicodemus, our Lord instances in a common natural case, and to which this affair of regeneration may be compared, and by it illustrated.
