Lust is adultery committed in the heart, making a man’s thought life just as morally accountable before God as his outward behavior. Escaping it demands ruthless, permanent sacrifice of whatever fuels it, because no earthly comfort or convenience is worth losing your soul in hell.

  1. There is an ancient, established moral law prohibiting adultery.
  2. Jesus positions His own authority alongside and above that ancient law (“But I say to you”).
  3. Jesus does not abolish the law against adultery — He intensifies it. </l

    You have heard that it was said to those of old, ‘You shall not commit adultery.’ But I say to you that whoever looks at a woman to lust for her has already committed adultery with her in his heart. If your right eye causes you to sin, pluck it out and cast it from you; for it is more profitable for you that one of your members perish, than for your whole body to be cast into hell. And if your right hand causes you to sin, cut it off and cast it from you; for it is more profitable for you that one of your members perish, than for your whole body to be cast into hell. Matthew 5:27–30

When Christian men struggle with pornography or sexual sin, the language they use to describe this battle matters more than they realize. Recently, some Christian ministries have adopted the term “unwanted sexual behavior” (USB) to describe what the Bible clearly calls sexual immorality, adultery, or fornication. While this softer terminology may seem compassionate or clinically precise, it fundamentally undermines biblical repentance and genuine freedom from sin.

Sin Reduced to Mere Activity

The phrase “unwanted sexual behavior” strips sin of its moral dimension and reduces it to a neutral activity that simply happens to be undesirable. It’s language borrowed from psychology, not theology. When we call pornography us
