The following link is to a series that has greatly encouraged and exhorted me. I share it with anyone who stumbles upon this site and challenge you to delve deep into discovering that there really is a spiritual battle going on all around us and in our lives. It doesn't have to look like The Exorcist or Paranormal Activity for it to become readily apparent when you start asking the Lord to help you take up your mantle as a warrior. I'm not saying it can't look like those things...I believe at times it can but none-the-less it is just as intense though it may be invisible. Enjoy and be blessed!
