I used to read a website this one person wrote.* And nowadays, a lot of things on that person's website bug me. But one statement has always bugged me more than any other. The person claimed that once you get into the occult, you "can't" get back out. That is false. Yes, you can get back out.
Tell the demons to leave you. In Jesus' name! And pray for protection.
That is all.
* If you're the person with whom I emailed in mid-late 2014 into early 2015, who talked to me about my CD collection, etc, I want to clarify that I'm not talking about you. This is someone else.
