1) Direct answer
Matthew 5:28–31 lifts the commandment to the heart level. Jesus says lust itself is adultery in the heart, and He tells us to deal ruthlessly with whatever causes us to stumble. He is not commanding literal mutilation, but a radical cutting off of the things and paths that feed sin. And in verse 31 He corrects the loose practice of divorce: marriage is holy; to put away a spouse without the one scriptural cause leads to adultery.

2) Scriptural explanation
- “Whosoever looketh on a woman to lust after her hath committed adultery with her already in his heart” (v.28). The Bible also says, “Out of the heart proceed… adulteries” (Matthew 15:19). So the root is inside.
- “If thy right eye offend thee, pluck it out… If thy right hand offend thee, cut it off” (vv.29–30). This is strong language showing the costliness of true repentance. Elsewhere the same warning is repeated (Mark 9:43–47).
- “It hath been said, Whosoever shall put away his wife, let him give her a writing of divorcement” (v.31). In the very next verse Jesus tightens this to God’s standard: “Whosoever shall put away his wife, saving for the cause of fornication, causeth her to commit adultery…” (v.32). He points back to God’s original intention—one flesh, not to be broken at will.

3) Simple clarifying logic
- Now notice: it isn’t the ball of the eye that sins; it’s the desire in the heart directing the eye. Pluck out one eye, can the other still lust? Cut off a hand, does that remove the thought that drives the hand? You see, the body is the instrument; the heart is the master. So Jesus calls us to “cut off” the causes and the channels—habits, places, screens, relationships, clothing, conversations, any path that feeds the fire. It’s better to lose a thing than to lose your soul.
- The true cure is an inside work: repent, believe the Gospel, and let God cleanse the heart. “Keep thy heart with all diligence; for out of it are the issues of life” (Proverbs 4:23). Make a covenant with your eyes like Job did (Job 31:1), and walk in the Spirit so the flesh doesn’t rule you.

4) Reinforcing statement
Jesus magnified the law to the inward man. Not three steps of self-mutilation, but one decisive surrender: cut off the stumbling blocks, and let God change the heart. Guard the marriage covenant as God does, and treat sin so seriously that nothing is too costly to lay aside to keep your soul.
