Daily word - backup?

In the movies a lone hero will go in to face his arch enemy alone in the final scene. In real world police and military organizations an officer will call for backup in any situation where it is helpful for victory or to achieve an objective. Overwhelming force reduces risk. How do you view your spiritual encounters with enemies? Are you confident in facing them alone? You should view your own situation more as real life than a staged encounter for dramatic effect, and the Bible uses plenty of martial imagery to describe spiritual warfare. There is no honor in facing your enemy alone. Who do you call for backup?
