Lasciviousness – What is it?

WHAT DOES THE BIBLE SAY?

The word “lasciviousness” is an older English term found only in the King James Version (six times). It is a translation of the Greek phrase aselgeia, which refers to shameless, unrestrained behavior, especially in sexual and moral matters. Most modern translations render it as “sensuality,” “debauchery,” or “depravity.” Jesus listed lasciviousness among sins that flow from the human heart, evidencing one’s inner corruption (Mark 7:21–22). Paul used it to warn the Corinthians away from unrepentant, immoral living (2 Corinthians 12:21). He also listed it among the “works of the flesh,” identifying it as a mark of a life ruled by sinful desire rather than the Spirit (Galatians 5:19). He noted that lasciviousness is the result of a hard heart that gives itself over to impurity (Ephesians 4:19). Similarly, Peter used the term to describe the sinful lifestyle believers were to have left behind (1 Peter 4:3). Jude warned that false teachers are known for lascivious living by twisting God’s grace to allow their debauchery (Jude 1:4).

FROM THE OLD TESTAMENT

• Lasciviousness is excessive, uncontrolled sexual desire or behavior that violates God’s commands and moral boundaries. Several passages in the Old Testament warn against lust, sexual immorality, and indulgence in sensual pleasures. For example, Genesis 6:5–6 shows that humanity’s wickedness, including lustful and corrupt behavior, grieved God, leading to judgment.
• The Ten Commandments forbid adultery and coveting, reflecting God’s call to sexual purity and restraint (Exodus 20:14; 20:17).
• Leviticus 18:6–30 emphasizes holiness and separation from lustful or immoral practices.
• The Israelites’ indulgence in sexual immorality with Moabite women brought God’s wrath, demonstrating the destructive consequences of lasciviousness (Numbers 25:1–3).Proverbs 6:25 and 7:21–23 warn against lustful thoughts and the seductive pull of immoral sexual behavior, which leads to ruin.

FROM THE NEW TESTAMENT

• Jesus included lasciviousness in a list of sins that proceed from the human heart: “For from within, out of the heart of men, proceed evil thoughts, adulteries, fornications, murders, thefts, covetousness, wickedness, deceit, lasciviousness, an evil eye, blasphemy, pride, foolishness” (Mark 7:21–22, KJV). Such behavior flows from one’s inner, sinful desires.
• Paul warned the Corinthians that unrepentant sin grieved him deeply, saying he feared he would come to the church only to find those who had not repented of “the uncleanness and fornication and lasciviousness which they have committed” (2 Corinthians 12:21, KJV).
• He listed lasciviousness among the “works of the flesh,” placing it alongside adultery and fornication. He said, “Now the works of the flesh are manifest, which are these; adultery, fornication, uncleanness, lasciviousness, idolatry, witchcraft, hatred, variance, emulations, wrath, strife, seditions, heresies, envyings, murders, drunkenness, revellings, and such …” (Galatians 5:19–21, KJV).
• Paul further described lasciviousness as the result of hardened hearts, writing of those “Who being past feeling have given themselves over unto lasciviousness, to work all uncleanness with greediness” (Ephesians 4:19, KJV).
• Peter used lasciviousness to describe the sinful lifestyle believers once lived before coming to Christ, listing it among practices that belonged to their former way of life (1 Peter 4:3, KJV). It represents behavior that Christians are called to leave behind.
• Finally, Jude warned that false teachers are known for turning God’s grace into license for sin. “For there are certain men crept in unawares, who were before of old ordained to this condemnation, ungodly men, turning the grace of our God into lasciviousness, and denying the only Lord God, and our Lord Jesus Christ” (Jude 1:4, KJV).

IMPLICATIONS FOR TODAY

Comedy scripts often rely on scenes where something doesn’t fit—the opera-loving sophisticate at a football game, the geek among jocks, the billionaire who stumbles through middle-class life for a day. It can be funny when things don’t fit. But shameless, unrestrained sin in the lives of believers doesn’t fit, and when we see it, it’s no laughing matter. God’s people are not to give themselves over to sensuality or debauchery, but to walk in self-control and purity. Lasciviousness describes a life driven by desire and a refusal to restrain sin, while the Christian life is defined by repentance and a growing desire to please the Lord rather than gratify the flesh.

The biblical warnings against this kind of living are addressed primarily to those who claim to belong to Christ. This is because only believers have been freed from the rule of the flesh and have been given the Holy Spirit, who empowers real change. Without Christ, people remain enslaved to sinful desires and lack the power to overcome them.

Believers who slip back into sensual or debauched living, should confess their sins to Christ (1 John 1:9) and seek help from their church leadership. Though the battle against the flesh doesn’t end when we become believers, God has given us all the tools we need to overcome it.

UNDERSTAND

• Lasciviousness is shameless, unrestrained sin, especially sexual or moral.
• Lasciviousness is a sign of inner corruption and rebellion against God.
• Believers are called to leave lasciviousness behind, pursuing purity and self-control through the Holy Spirit.

REFLECT

• Where in your life might unrestrained desires be influencing your thoughts or actions, and how can you surrender them to God?
• How do you seek to examine your heart and motives for sin?
• In what ways are you actively pursuing purity and self-control through the power and illumination of the Holy Spirit?

ENGAGE

• How does the Bible’s warning against lasciviousness connect to broader teachings on the “works of the flesh” and our call to holiness?
• How can we help each other resist a lifestyle of unrestrained sin?
• How does understanding the Old Testament examples of consequences for lustful or immoral behavior deepen our awareness of God’s call to purity today?
