Spiders never just go away. You have to kill them otherwise they keep building more and more webs. You can clean the web out and next thing you know the spider is building a new one---over and over and over again---until you finally kill that spider. Many have a "secret place" in their life that Satan is repeatedly building webs and not until you name it and kill it will you ever be truly free and that only is possible through Jesus Christ and His power!
