Possession - in every sense of the word

I just had this thought pattern that filled me with such joy I had to get it down into words. I hope it comes out right. I was in the shower and thinking about possession. I know....but stay with me. I have seen a lot of commercials lately for scary movies about possessions and I was thinking how powerful and scary these events are and I thought to myself about he word "possession " and my mind was wondering why aren't there "good" possessions by angels or good spirits flying around possessing people to do something awesome and as soon as I ask the question the answer was there in my mind. God does not have to send spirits or use tricks to get inside us, we are extensions of him! He is already present inside of all of us. He is omnipotent because we are all parts of him. You don't say you posses your finger, because its your finger. Now, if someones cuts your finger off and puts it in their pocket THEN they posses it. Like your finger, if you choose to wiggle it you simply wiggle it and you automatically know its happened but if someone ELSE wants to you to wiggle your finger then they must either convince you to do so or force you to do so. This is exciting to me because it means God is already in us the devil is not! He is not omnipotent and he does not have possession of us, we are first and foremost Christ's. If God chooses to do good through you he simply awakens the parts of him that are already inside your fiber, and your heart. He wiggles his finger so to speak. Why is this so exciting to me? Why am I going on and on about it? Because it means the devil must work hard for evil to abound he must stay up walking to an fro he must exhaust himself day and night and send spirits into people to control and change them. Oh but here is what makes me excited, for The Lord my God to do good all he must do is stretch out his finger!
