Concupiscence is the technical theological name for what Paul calls "sinful passions" (Rom. 7:5), "evil desires" (Col. 3:5), and the law of sin "in my members" (Rom. 7:23). It is the experience every regenerate man knows: you know what is right; you desire to do what is right; and yet there is another desire — a pull in the opposite direction — that wars against the Spirit within you (Gal. 5:17). This is not mere temptation from without — it is the residual corruption of the old nature that remains even after regeneration, what the Reformers called indwelling sin or the flesh. The great battle of the Christian life is not fought on the internet or in bars or in bad company alone — it is fought in the inner man, against the desires that arise from within (Jas. 1:14–15).
James traces the anatomy of sin with precision: "each person is tempted when he is lured and enticed by his own desire [epithumia, concupiscence]. Then desire when it has conceived gives birth to sin, and sin when it is fully grown brings forth death" (Jas. 1:14–15). The man who understands concupiscence understands why holiness requires not merely behavioral restraint but the mortification — the killing — of the desires themselves (Col. 3:5; Rom. 8:13). Paul's command is not "manage your lust" but "put it to death." This is daily, violent, necessary war. The man who does not wage it will be conquered by his own desires.
CONCUPISCENCE, n. [L. concupiscentia.] Lust; unlawful or irregular desire of sexual pleasure; in a wider sense, the coveting of carnal things, or an irregular appetite for worldly good; sensual desire. In theology, the corruption of natural appetites, as existing in fallen humanity — the inward bent toward sin that remains in the regenerate and against which the Christian must continually strive. Rom. vii. 8; Col. iii. 5.
The modern therapeutic framework has effectively erased concupiscence as a theological category. What Scripture calls disordered desire — lust, covetousness, pride, self-will — is now relabeled as "authentic self-expression," "natural orientation," or "psychological need." The category of disordered desire is abolished by reclassifying all desire as inherently neutral or good. This is not a minor semantic adjustment — it is the destruction of the entire Christian doctrine of sin at the experiential level. If no desire is intrinsically disordered, then no desire requires mortification. And if nothing requires mortification, there is no battle, no victory, no holiness — only the endless accommodation of appetite. The Reformers, Augustine, and the NT itself are unambiguous: fallen man's desires are bent away from God and toward self. They are not to be expressed; they are to be killed. This is not cruelty; it is surgery.
Romans 7:7–8 — "I would not have known what it is to covet if the law had not said, 'You shall not covet.' But sin… produced in me all kinds of covetousness [concupiscence]."
Colossians 3:5 — "Put to death therefore what is earthly in you: sexual immorality, impurity, passion, evil desire [epithumian], and covetousness."
James 1:14–15 — "Each person is tempted when he is lured and enticed by his own desire. Then desire when it has conceived gives birth to sin."
Galatians 5:16–17 — "Walk by the Spirit, and you will not gratify the desires of the flesh. For the desires of the flesh are against the Spirit."
Romans 8:13 — "If by the Spirit you put to death the deeds of the body, you will live."

G4561 — σάρξ (sarx) — flesh; Paul's term for fallen human nature in its rebellion against God. The seat of concupiscence. "The works of the flesh" (Gal. 5:19) are concupiscence in action.

• "Concupiscence does not shout. It whispers. It does not command — it suggests. The man who does not mortify it daily will find that yesterday's whisper is today's habit."
• "Paul's experience in Romans 7 is not testimony to Christian defeat — it is testimony to the ongoing nature of the war. The man who no longer feels the pull of concupiscence has either achieved glorification or stopped fighting."
• "The father who does not understand concupiscence cannot train his sons. You cannot defeat an enemy you refuse to name."
