Discernment - Your ability to discern what you are fighting against is crucial to your victory. Most bad spirits are not easily identified for their survival actually depends on their ability to conceal their identity. If you don't know what you are fighting against, you will not know how to overcome the enemy. Those who understand the art of warfare know that violence is a very vital weapon in the spiritual realm. In real life, nobody expects you to fight physically but in the spiritual realm, you could be as ruthless as anything.
