To keep you from the evil woman, from the flattering tongue of a seductress. Do not lust after her beauty in your heart, nor let her allure you with her eyelids. For by means of a harlot a man is reduced to a crust of bread; and an adulteress will prey upon his precious life.
In the Proverbs, Solomon repeatedly warns his son, and young people in general, about the dangers of sexual sin. Temptations have been present in every age, but none more blatantly than in our sexually liberated Western world. Flattery and professions of love added to alluring looks can cloud our minds to the dangers of premarital and extramarital sex. Sexual sin threatens poverty in this life and carries the penalty of eternal death if not repented of.
Harboring thoughts of lust is itself a sin, Jesus Christ tells us (Matthew 5:28). We must mentally and physically “flee sexual immorality” (1 Corinthians 6:18).
