What does Matthew 18:8 mean?

If your hand or your foot is causing you to mess up, cut it off and throw it away. It’s better to live with one hand or foot than to be thrown into the fire with both. Matthew 18:8 - Modern Text Bible

(He’s using strong language to say that it’s better to lose something important than to let it destroy your whole life. The point is about removing whatever leads you to do wrong.)
