I came across this revelation as I was furiously scribbling away at my own shortcomings one night in late February, and I'd like to explain my opinion on this.
First, you must under stand that I use the root word "sin" loosely. I do not mean in a religious sense, as it most often is used in connotation with. "Sin" in this sense simply means "morally wrong", or, even, wrong to one's self.
Now, most people refer to inner demons as a need or a want that a person battles with mentally, and sometimes, physically. Take, for example, excessively drinking liquor, or for some people, drinking at all. Or, better yet, take the teenage mind's idea of love. Almost every teenager claims to love whoever they may be dating, and, in a sense, they do. They feel a strong feeling of affection for someone and that feeling is returned. However, the teenage mind and body goes through multiple changes, and, the person becomes attracted to someone else as well. At that point, the choice of dating the other person, staying with the current date, or cheating on the current date with the other person, is a rather large conflict, testing your morals and perspective on life, and the resulting choice can be an inner demon.
The phrase "sinner demands" can be applied to either of those two examples, and any other that I've come across. Drinking in excess is a sinner demand. Using the definiton of sin from above, if you drink in excess and know you need to stop, then the liquor is a demand of yours, and you are a sinner. If you cheat on your date, and you know you shouldn't have, or feel any remorse over it, then the other person was your demand, and you are a sinner.
I llike your blog however "inner demons" is something only those who come into contact with will understand,what you describe is "addiction" and by this is an influence outside of the body as in temptation,a temptation to take drugs,drink,smoke and such,,but it is those "demons"that come from within that are the most distructuve and can very rarely be overcome by words,its a life thing,,however taking temptation results in the catching the demons attention.
To call someone a sinner is a view of those who feel they are above sin and this itself must be a sin as well..
I respect your personal views so no offence dude..we all have our own beliefs.
And, it's not necessarily an addiction, though all addictions fall under the category. It could be something you've never done before. Taking a drug isn't an addiction the first time, it's an addiction after you've done it repetitively to satisfy a need that grows each time you do it (Well, that's the best way I can put it). Also, I believe temptation is a fuel for an "inner demon", rather than the demon itself. I don't really think there's a word that sums up "inner demons". I think the best way to put it is "anything that forces a struggle between your morals and your wants".
And, no, man, it's totally cool. I post these to hear other people's opinions and beliefs, and to throw my own out there. I enjoy these types of discussions.
