4. It has been abundantly proved above, that godly sorrow and true faith thoroughly change a man; that they crucify the flesh, effect an entire transformation in the soul, and beget, through the Holy Ghost, a new life. Lest, however, this should be a mere theoretical knowledge, devoid of life and practice, God has been pleased to set before us his own Son, not only as a ransom and a Mediator, but also as a mirror of perfect godliness, and as a most finished pattern of the new man, who is regenerated after the image of God. In him, the fleshly Adam, the corrupt nature, never reigned; but the blessed God alone. Him it hath pleased God to set forth before our [pg 030] eyes, that, contemplating him and his righteous life, we might be daily more and more renewed after his image. Let us explain this point more fully.
5. Sad experience teaches us continually, that our whole nature, body and soul, is polluted with every kind of sin, vice, and corruption. These are the works of the devil appearing in the carnal man; and it is principally in the depraved and perverted will, that these diabolical operations are most visibly discerned. For the depraved will is the root of all sin: if that were removed, there would be sin no more. With regard to the power and natural bias of this will, it consists chiefly in turning man away from God and from His will. Now, whatever departs from that Being who is the sovereign and supreme Good, cannot but be in itself evil; for it partakes of the nature of the supreme evil, and is a violation of the original constitution of our nature, as derived from God himself. It was this turning away from God that produced the fall both of Satan and of man; whence sin entered into the world, and has, by fleshly generation, passed upon all men.
6. The nature of man is then inoculated with the nature of the devil himself, and his will tainted with satanical wickedness, as with deadly poison. Hence Christ called the Pharisees “children of the devil” (John 8:44); and even to one of his own disciples gave the name of Satan (John 6:70); intimating as though the covetousness, lying, pride, and evil concupiscence, by which the nature of all men is defiled, were Satan himself.
7. Hence it may, with all propriety, be affirmed, that they who lead a life void of repentance, a life of pride, avarice, lust, and envy, live in the devil, and partake of his nature. Such persons may assume the garb of honesty; they may veil their real characters under a fair show of morality and correct deportment; yet, inwardly, according to the saying of Christ to the Jews, they are, nevertheless, devils. John 8:44. Such a declaration is dreadful to be made; but the truth of it is confirmed, both by the Word of God and by continual experience.
8. Our nature, as fallen creatures, being thus miserably depraved, thus desperately perverted, and vitiated in all its springs; there is an absolute necessity that it should be purified and renewed. There must be a total renovation of the soul, in all its powers and all its faculties. But how shall this be effected? We answer: As the chief evil has made a breach upon our nature, and has infused poison into its very springs; so must the chief Good revisit and renew our nature, that it may be assimilated to itself. That which the supreme evil has so radically corrupted, can be corrected only by a thorough and vital penetration of the supreme Good, even of God himself; and, therefore, it was necessary that the Word should be made flesh.
9. The Son of God truly became man, not for his own sake, but for our sakes; that, by reconciling us to God by himself, he might make us partakers of the sovereign good, having cleansed and sanctified us, to that end; for whatever is to be sanctified, must be sanctified by God and with God. And as God is in Christ, so ought we to be united to him by faith, that we may live in God, and God in us; we in Christ, and Christ in us (2 Cor. 5:19, 21); that the will of God be in us, and we in the will of God, being made the righteousness of God in Christ. 2 Cor. 5:21. This is the only way in which Christ administers [pg 031] medicine to our corrupt nature; and the more powerfully he influences man, the more thoroughly will human nature be purified.
10. Oh! how blessed is the man in whom Christ does all and is all; whose will, thoughts, mind, and words, are the will, thoughts, mind, and words of Christ! It was thus the apostle said, “We have the mind of Christ.” 1 Cor. 2:16. And so indeed it must be with the believer; because the life of Christ is the new life, yea, the new man in him; and whoever lives in Christ after the Spirit, hath really put on the new man, and all the graces with which he is adorned. His meekness and obedience are the meekness and obedience of Christ; his patience and humility are the patience and humility of Christ; and his life itself is the life of Christ, by whom and in whom he lives. This is the “new creature” which is created after God (2 Cor. 5:17); and that life of Christ in us, of which St. Paul experimentally says, “I live, yet not I, but Christ liveth in me.” Gal. 2:20. This is to follow Christ truly. This is to walk in the light of his life, and to bring forth “fruits meet for repentance;” for, by this means, the “old man” is destroyed, the carnal life gradually declines, and the new and divine life is established in the soul. He who has this life is not a nominal, but a real Christian; a Christian not in word and in appearance only, but in deed and in truth. He is a true child of God, begotten of Him, and quickened and renewed by faith after the image of Jesus Christ.
11. Although we cannot attain to a state of perfection, while encompassed with so many infirmities that obstruct our progress in the divine life, we ought not, therefore, to be discouraged, but rather to be inspired with more fervor in seeking after a consummation so much to be desired. We ought ardently to wish and pray, to endeavor and study, that the kingdom of Christ be established within us, and the kingdom of Satan destroyed. 1 John 3:9; Eph. 2:5. The object of our cares and efforts, of our groans and prayers, should be—how we may more and more mortify the old man by daily repentance. For, the more a man dies to himself, the more Christ lives in him; the more corruptions are removed by the good Spirit of God, the more divine grace possesses the heart. In proportion as the flesh is crucified, the spirit is quickened; as the works of darkness are put off, the armor of light from above is put on; and in the same degree as the outward man perisheth, the inward man is strengthened and renewed. 2 Cor. 4:16; Col. 3:5. The decrease of the carnal life, is the increase of that which is spiritual and divine. As the affections of the former, self-love, ambition, wrath, covetousness, and voluptuousness, are weakened and subdued, so are opposite affections of the spiritual life invigorated and raised. The farther a man departs from the world, from “the lust of the flesh, the lust of the eyes, and the pride of life” (1 John 2:16); the more do God, Christ, and the Holy Spirit enter into the heart and dwell there. And, on the other hand, the more nature, flesh, darkness, and the world, reign in man; the less of grace, light, the Holy Spirit, God, and Christ, is there to be found in him.
12. This spiritual life is enmity to the flesh, because the latter is hereby restrained, subdued, and brought under the yoke, and crucified with its “affections and lusts.” In this, however, consist the power, efficacy, and fruit [pg 032] of true repentance. The nature of flesh and blood is to lead a lawless, dissolute, and voluptuous life, unshackled by restraint, and entirely agreeable to its own will and humor. It is this which it finds sweet, and in which it rejoices. To the flesh and the “old man,” the life of Christ is a most severe cross, and an intolerable burden; but to the new and spiritual man, “this yoke is easy and this burden light” (Matt. 11:30), and attended with divine serenity and peace of mind. For the true rest of the soul will be sought for in vain, unless in faith in Christ; in his meekness and humility, patience and love. Here he hath himself promised, “Ye shall find rest unto your souls.” Yea, he that really loves the Lord Jesus, will not deem it hard to suffer even death for his sake, but account it a joy and a happiness. Such is the yoke of the Saviour, which we are invited to take upon us, that we may find “rest unto our souls.”
13. It is necessary, therefore, that every one who is resolved to take upon himself the yoke of Christ, and to imitate His holy example, should, in the first place, shake off the yoke of Satan, and repress the carnal, selfish, and unruly propensities of his fallen nature, in order that the flesh may vex the spirit no more. All must be subjugated to the obedience of Christ, to the wise and righteous discipline of his law; that is, the will, understanding, reason, and appetites, together with the sensual desires of the old Adam, that before reigned in the mortal body, must henceforth yield a free obedience to the government of the Lord. Rom. 6:12.
