And that the name "flesh" doth primarily signify the sensitive appetite itself, is evident in the very notation of the name. Why else should the habits or vices of the rational powers be called "flesh" any more than "spirit," or anything else? If it were only in respect of their object, they should be called "the world" also, because that is their object. It is a certain rule, that That faculty is most predominant in man, whose object is made his chiefest end. Sensitive delights being made the felicity and end of the unsanctified, it followeth that the sensitive faculties are predominant; which being called "flesh," (by a nearer trope,) the mind from it receives the denomination. The Scriptures also show this plainly: I remember not any one place in the Old Testament where there is any probability that the word "flesh" should signify only the rational soul as unrenewed. Matt. xvi. 17, "Flesh and blood hath not revealed this unto thee;" that is, mortal man hath not revealed it. Matt. xxvi. 41, "The spirit is willing, but the flesh is weak;" that is, your bodies are weak, and resist the willingness of your souls: for sinful habits are not here called weak. John iii. 6, "That which is born of the flesh is flesh;" that is, man by natural generation can beget but natural man, called "flesh" from the visible part; and not the spiritual life, which nature is now destitute of. Rom. vii. 25, "With my flesh I serve the law of sin;" that is, with my sensitive powers, and my mind so far is captivated thereto. Rom. viii. 1, 5, flesh and spirit are oft opposed: "They that are of the flesh, mind the things of the flesh," &c.; that is, they in whom the sensitive interest and appetite are predominant: for it is called "the body" here, as well as "the flesh," ver. 10, 11, 13. The mind is here included; but it is as serving the flesh and its interest. Gal. v. 16, 17, 19, flesh and spirit are in the same manner opposed. And 2 Pet. ii. 18, the lusts of the flesh are in this sense mentioned. And Eph. ii. 3; Rom. vii. 18; xiii. 14; 1 Cor. v. 5; 1 Pet. ii. 11; in which there is mention of "fleshly lusts, which fight against the spirit," and "fleshly wisdom, making provision for the flesh," &c. And Col. ii. 18, there is indeed the name of a fleshly mind, which is but a mind deceived and subservient to the flesh; so that the flesh itself, or sensitive interest and appetite, are first signified in all or most places, and in some the mind, as subservient thereto.
It is of the greater consequence that this be rightly understood, lest you be tempted to imitate the libertines, who think the flesh or sensitive part is capable of no moral good or evil, and therefore, all its actions being indifferent, we may be indifferent about them, and look only to the superior powers: and others, that think that the Scripture by "flesh" meaneth only the rational soul as unrenewed, do thereupon cherish the flesh itself, and pamper it, and feed its unruly lusts, and never do any thing to tame the body; but pray daily that God would destroy the flesh within them, that is, their sinful habits of reason and will, while they cherish the cause, or neglect a chief part of the cure. And on the contrary, some papists that look only at the body as their enemy, are much in fastings, and bodily exercises, while they neglect the mortifying of their carnal minds.
What flesh-pleasing is a sin.
II. How far flesh-pleasing is a sin, I shall distinctly open to you in these propositions: 1. The pleasing or displeasing of the sensitive appetite in itself considered, is neither sin nor duty, good nor evil; but as commanded or forbidden by some law of God; which is not absolutely done.
2. To please the flesh by things forbidden is undoubtedly a sin, and so it is to displease it too. Therefore this is not all that is here meant, that the matter that pleaseth it must not be things forbidden.
3. To overvalue the pleasing of the flesh is a sin; and to prefer it before the pleasing of God, and the holy preparations for heaven, is the state of carnality and ungodliness, and the common cause of the damnation of souls. The delight of the flesh or senses is a natural good; and the natural desire of it in itself (as is said) is neither vice nor virtue: but when this little natural good is preferred before the greater spiritual, moral, or eternal good, this is the sin of carnal minds, which is threatened with death, Rom. viii. 1, 5-8, 13.
4. To buy the pleasing of the flesh at too dear a rate, as the loss of time, or with care and trouble, above its worth, and to be too much set on making provisions to please it, doth show that it is overvalued, and is the sin forbidden, Rom. xiii. 14.
5. When any desire of the flesh is inordinate, immoderate, or irregular for matter, or manner, quantity, quality, or season, it is a sin to please that inordinate desire.
6. When pleasing the flesh doth too much pamper it, and cherish filthy lusts, or any other sin, and is not necessary on some other account, as doing greater good, it is a sin. But if life require it, lust must be subdued by other means.[277]
7. When pleasing the flesh doth hurt it, by impairing health, and so making the body less fit for duty, it is a sin. And so almost all intemperance tendeth to breed diseases; and God commandeth temperance even for the body's good.
