Screwtape and Wormwood: Who are they?

Hi all,
I was planning my next entry to be about the URL I chose for this blog and open up discussion on "love." However, my heart changed a bit as I was studying for a class I'm taking through WHC--a spiritual warfare class. I came across an excerpt from my reading, which is an excerpt from The Screwtape Letters by C.S. Lewis. For those of us who don't know, Screwtape is a powerful, well experienced devil training his nephew Wormwood into the ways of becoming a powerful devil.
"My dear Wormwood...Even if a particular train of thought can be twisted so as to end in our favor, you will find that you have been strengthening in your patient the fatal habit of attending to universal issues and withdrawing his attention from the stream of immediate sense experiences. Your business is to fix his attention on the stream. Teach him to call it "real life" and don't let him ask what he means by "real"...Never having been a human, you don't realize how enslaved they are to the pressure of the ordinary."
I've taken up interest in spiritual warfare for a number of reasons--one, being that as a Christian, it's my duty to fight these principalities in my life and in others. Another of the reasons is that I believe my life was recently, and greatly, affected by "real life" causing a large change in my mindset on myself and life. I wouldn't say I've become unfixed on God--but I even went to a point of just giving up. I'm thankful I didn't--but I'm still left in ruins trying to understand it all. God has been teaching me much, and healing me a ton; but I'm still left with the why's and how's and can I do anything more? While it's too late to correct what had happened, I can pray and keep the reins of control in God's hands. It's just so disturbing to me that those also affected by this recent, prolonged attack aren't on guard and in effect--giving satan the victory by not rebuking it.
I know it's not an easy fight--I'm plagued with it daily; but I am learning. Keeping my focus on what is real and not the perceived real is a challenge; and the thoughts that go along with it are even more troublesome to sort out--is that real or is that "real"? I know the absolute answer is God--trust in Him, remain in Him, etc. etc., but as a seeker of knowledge and understanding, what do I do with my head? It would be nice to exchange it for a "clean" one--but my soul would inevitably corrupt that one as well. I know what I seek and I strive for it daily--but then, what do I do about something I seek and cannot control the outcome even when I know God is heavily involved? Nevermind the whirlwind of thoughts that go with it, and the analyzing of those thoughts just adds more thoughts--whoosh, a hurricane is born.
All I do now is push the thoughts aside, negating any of them any amount of truth/deceit--releasing me from the hurricane--but I know that isn't the answer either. I give it to God constantly--but yet, I'm still deceived and take it back under the lie that those thoughts are "real" and I need them. It's a mystery--one that I may never solve--and even that bugs me too. Errg. I'm sure this isn't the end of this topic, but it ends this entry.
