There are two primary errors when it comes to spiritual warfare—over-emphasis and under-emphasis. Some blame every sin, every conflict, and every problem on demons that need to be cast out. Others completely ignore the spiritual realm and the fact that the Bible tells us our battle is against spiritual powers. The key to successful spiritual warfare is finding the biblical balance. Jesus sometimes cast demons out of people; other times He healed people with no mention of the demonic. The apostle Paul instructs Christians to wage war against the sin in themselves (Romans 6) and warns us to oppose the schemes of the devil (Ephesians 6:10–18).
