I have an incredibly addictive nature. I've always been that way. If I find something that makes me feel good, something I enjoy, I take it to the extreme.
Even good things in excess can be sinful. So how much worse is being excessive in those things which are flat-out bad to begin with.
Well satan only needs the most tiny of footholds in your soul to completely devour and destroy you! You think he wastes time trying to convince you to murder and rape? Doubt it. He knows our weaknesses. He knows that all he needs to get us to do is take that one extra piece of cake when you're full, to have that one single beer or cigarette with a friend, to watch just one episode of that funny television show, to watch that one popular movie, to read that one worldly book.
It's not the type of the sin or the size of the sin...it's the fact that you made a conscious decision to forsake Christ and go your own way. And having made that decision, you kick the Spirit out of your heart and invite satan and his demons in.
In your own mind you think the battle has just begun, that you've opened the door to a battle of willpower against the devil. That you won't have any more after this one. The truth is that the moment you think the battle is starting, you've already lost. It's the little things that are so vital to the Christian walk.
God help me with the little things!
