4. Learn from this, the nature and necessity of regeneration. First, This discovers the nature of regeneration in these two things, (1.) It is not a partial, but a total change, tho' imperfect in this life. Thy whole nature is corrupted, and therefore the cure must go through' every part. Regeneration makes not only a new head for knowledge, but a new heart, and new affections for holiness. All things become new, 2 Cor. v. 17. If one who has received many wounds, should be cured of them all, save one only, he might bleed to death, by that one, as well as a thousand. So if the change go not through the whole man, it is naught. (2.) It is not a change made by human industry, but by the mighty power of the Spirit of God. A man must be born of the Spirit, John iii. 5 Accidental diseases may be cured by men, but these which are natural, not without a miracle, John ix. 22. The change wrought upon men, by good education, or forced upon them, by a natural conscience, tho' it may pass among men for a sav•ing ⟨p. 85⟩change, it is not so; for our nature is corrupt, and none but the God of nature can change it. Tho' a gardiner, ingrafting a pear branch into an apple tree, may make the apple-tree bear pears; yet the art of man cannot change the nature of the apple-tree: so one may pin a new life to his old heart, but he can never change the heart. Secondly, This also shows the necessity of regeneration. It is absolutely necessary in order to salvation, John iii. 3 Except a man be born again, he cannot see the kingdom of God. No unclean thing can enter the new Jerusalem: but thou art wholly unclean, while in thy natural state. If every member of thy body were disjointed, each joint behoved to be loosed, ere the members could be set aright again. This is the case of thy soul, as thou hast heard: and therefore thou must be born again; else thou shalt never see heaven, unless it be far off, as the rich man in hell did. Deceive not thyself: no Mercy of GOD, no Blood of CHRIST will bring thee to heaven, in thy unregenerate state: for God will never open a fountain of mercy, to wash away his own holiness and truth: nor did Christ shed his precious blood, to blot out the truths of God, or to overturn God's measures about the salvation of sinners. Heaven! What would you do there, that are not born again? Ye that are no ways fitting for Christ the head.
