Strong, disordered desire — the craving of what God has not given or what God has forbidden — that enslaves the heart and leads to death. In its broadest biblical sense, lust is not confined to sexual desire; it includes coveting, greed, pride, and any longing that displaces God as the soul's supreme satisfaction. Israel "lusted intensely in the wilderness" — not for sexual immorality but for the food of Egypt (Numbers 11:4; Psalm 106:14). James traces the entire pathway: "Each person is tempted when he is lured and enticed by his own desire. Then desire when it has conceived gives birth to sin, and sin when it is fully grown brings forth death" (James 1:14–15). Jesus names the critical point: lust fully entertained in the heart is already adultery (Matthew 5:28).
LUST, n. Longing desire; eagerness to possess or enjoy. In an ill sense, unlawful desire of carnal pleasure; libidinous craving. In Scripture, lust is extended to all sinful desires: "Thou shalt not covet" covers every form of disordered longing for that which belongs to another or which God has not appointed. The lusts of the flesh, of the eyes, and the pride of life constitute the world-system that opposes the Father.
Modern culture has fully rehabilitated lust, rebaptizing it as "desire," "passion," "authenticity," or "following your heart." The notion that strong desire should be resisted rather than followed is treated as repression, trauma, or religious abuse. The sexual revolution specifically targeted sexual lust and declared its gratification a human right. The result is not freedom but accelerating addiction, relational destruction, and spiritual death on an industrial scale. Scripture is not anti-desire — God created desire and declared it good. What Scripture names as lust is desire untethered from covenant, from the other person's dignity, from God's design. The antidote is not suppression but satisfaction in Christ — the one who alone can fill what lust promises and cannot deliver.
