Ok here's the problem there is a demon in my basement. I have always been sensitive to this kind of thing and I know its true. I have blocked it in one room but all my attempts to exorcise it have failed to the point where the demon is mocking me. I went down there to try again today and mark 3 was written on the wall. I looked it up and there is a verse there saying all shall be forgiving but those who mock god. What do I do.
