Christians: What do you think about this scripture?

That's one of our favorite pages. It sure does apply to us. If we're not spiritually protected, we are powerless against satan and the demons. We need God's power and protection to do and be what He has for us to do and be. Our weapons are spiritual as detailed in the page above. Prayer, having scripture be part of us through study, and, above all, faith, which is a gift from God the Holy Spirit.
