What does Jude 1:19 mean by "natural instincts"? Full Text “These are the ones who cause divisions, who are worldly [lit. ‘natural’] and devoid of the Spirit.” — Jude 1:19 Context in Jude Jude writes a short, urgent letter warning believers about infiltrating teachers who pervert grace (v. 4). Verses 17–23 form a single unit: the apostles predicted mockers (cf. 2 Peter 3:3); Jude points out their marks, then exhorts the church to stand firm. Verse 19 is the center of that unit, identifying the intruders by three traits: (1) they splinter fellowship, (2) they operate on “natural instincts,” and (3) they lack the Holy Spirit. All three clauses are present participles in Greek, marking ongoing habit rather than a lapse. Contrast: Psychikos vs. Pneumatikos Paul sets the standard contrast (1 Corinthians 2:14–3:1). The psychikos man, governed by unregenerate reason, finds the gospel foolish; the pneumatikos discerns because he is indwelt by the Spirit (Romans 8:9,14). Jude leverages the same dichotomy: the intruders lack the Spirit, hence can act only from psychikos drives. “Natural Instincts” Explained A. Not Mere Biology Alone God created appetite, emotion, and intellect as “very good” (Genesis 1:31). Sin corrupted these faculties (Jeremiah 17:9; Ephesians 4:17-19). Operating solely by psychē means functioning at the level of fallen human impulses—self-preservation, status, lust, tribalism—without the correcting governance of the indwelling Spirit. B. Morally Descriptive “Natural” here is not neutral; Jude parallels psychikoi with divisions and Spirit-lessness. James 3:15 adds the moral triad “earthly, natural, demonic.” The teachers’ instincts align with the world system that “lies in the power of the evil one” (1 John 5:19). C. Behavioral-Scientific Corollary Modern cognitive science confirms that unregulated limbic impulses (fight-or-flight, mating, power acquisition) dominate when prefrontal moral reasoning is disengaged. Scripture anticipated this: “their god is the belly” (Philippians 3:19). Regeneration introduces new motivational structures (Galatians 5:16-25) that secular neurobiology alone cannot account for—an empirical pointer to the necessity of the Spirit. Old Testament Foreshadowings • Esau (Genesis 25:34) despised his birthright for immediate appetite—prototype of psychikos living. • The sons of Eli (1 Samuel 2:12-17) “did not know the LORD,” yet ministered in the sanctuary—Jude’s intruders reenacted that pattern. Cross-References Natural-Impulse Living: Romans 8:5-8; 1 Corinthians 3:3; Galatians 5:19-21. Spirit-Empowered Living: Ezekiel 36:26-27; John 3:6; Romans 8:9-14; Galatians 5:22-25. Practical Application • Guard Unity: Do not let psychikos counselors divide Christ’s body (Ephesians 4:3). • Cultivate Spiritual Disciplines: Word saturation, prayer, fellowship, and communion seek Spirit directive over natural impulse (Acts 2:42). • Evangelize the Psychikos: Reason with them (Acts 17:2-4) yet recognize that conversion hinges on the Spirit’s illumination (2 Corinthians 4:6). Conclusion “Natural instincts” in Jude 1:19 translates ψυχικοί—people limited to fallen human life, lacking the Holy Spirit. Their modus operandi produces division and sensuality, exposing their unregenerate state. The remedy is the gospel’s regenerating power, moving men and women from psychikos existence to Spirit-filled life that glorifies God. |
