There are different arenas in which we can choose to do spiritual warfare. There is civilian (agricultural), courtroom, and battlefield warfare. God truly wants prayer to be preventative in our lives. We can have things theologically that we don't yet have experientially. Intercession is meant to bring what we have theologically into reality. Jesus and His 12 never experienced sickness, tragedy, or loss. They were always on the offensive, solving other people's problems, healing the sick, and casting out demons. God desires for us to live in a place of security and safety so we can go out and fight other people's battles, rather than being stuck fighting our own.
