What does it take to make an exorcist? Compassion. The sufferer is not your target, he/she is the person Jesus wants set free. Doing violence to the individual is not needed or acceptable. Blaming or being judgmental of the person seeking aid is not what Jesus came to earth to do. He came to destroy the works of the devil, not the people he came to save. You must listen. You may hear heartbreaking, nauseating confession. You must be able to do this. Then gently prod the sufferer to bring their sinful thoughts, inclinations, identity, and deeds to Jesus in repentance. If you cannot do this, then rest assured, you are not ready.
