For to be carnally minded is death
The phrase the apostle here uses, includes the best part of corrupt man; the mind, the understanding, the judgment, the will, the affections, the thoughts, the reason, and reasonings of man; and may be rendered, "the wisdom", or "prudence of the flesh"; so called, to distinguish it from that wisdom which is from above; from that natural and civil wisdom, which is laudable; and it shows that the wisest part of man is but carnal: all sorts of persons destitute of the grace of God are concerned herein; or this is applicable to them all, as the sensualist, the worldling, the proud Pharisee, and the wise disputer of this world. This wisdom of the flesh, or carnal mindedness, "is death"; not that it is conversant about death; or that such persons are thoughtful of it, endeavour to make it familiar to them; or are desirous of it, and esteem it as a privilege; this only spiritually minded men do: but the sense is, that this issues in death; death is not the object, but the end of carnal mindedness; carnal mindedness, so far as it prevails in the saints, brings a death upon them. It is true, indeed, they cannot die a spiritual, or an eternal death; yet sometimes they are very dead and lifeless in their frames, in the exercise of grace and discharge of duty; which is frequently owing to their carnality: and the effect of this must needs be death in carnal men; since it alienates from God; it renders them transgressors of the law, and obnoxious to its curse; it sets the soul against, and diverts it from Christ the way of life; and if grace prevent not, must be the cause of, and issue in eternal death; because it is sin and sinful, it is enmity to God, it disqualifies for life, and makes persons fit companions for the heirs of wrath:
but to be spiritually minded, is life and peace;
spiritually minded men are the only living persons in a spiritual sense, for all that are in and after the flesh are dead; and so far as carnal mindedness prevails in professors, there is a deadness in them as to all spiritual exercises; and oftentimes as to outward appearance, there is no difference between them and dead men: but spiritually minded men are evidently living persons; they have a spiritual discerning of spiritual things; they breathe after them, savour and relish them; they talk of spiritual things, and walk in a spiritual manner; they are not only alive, but lively in the exercise of grace and discharge of duty; and are the means of enlivening others; and their end will be everlasting life; which is certain from the declared will and promise of God, and from the grace of life and Spirit of life which are in them. "Peace" also is another effect of spiritual mindedness; such enjoy peace of conscience: this is a fruit of the Spirit; a part of the kingdom of grace the are possessed of; and the things their minds are conversant with are productive of it; which is the gift of God, passes all understanding, and is of more worth than all the world: such men are also of peaceable dispositions in commonwealths, in neighbourhoods, in families, and churches; induced thereunto by the noblest arguments; and their end will be peace, which will be perfect and eternal.
