According to Les, how should a Christian deal with someone who is demon possessed?
A Christian has no Grace Age instructions for casting out demons, because Paul never gives the Grace Age believer any. The only approach this teaching is content with is that the person probably needs salvation: present the Gospel, and if genuinely born again, that should take care of the demon possession.
Les explains that he is uncomfortable with exorcism and casting out demons because the Apostle Paul never once gives the Grace Age believer instructions for dealing with demon possession. The only way he is content about dealing with it is that the person probably needs salvation; if we can present them with the Gospel and see them genuinely born again, then that will take care of their demon possession. He says he does not set those things in concrete and others may disagree. In the Samaritan account, unclean spirits cried out and came out of many who were possessed, and there was great joy in the city; yet when things go well, the devil brings a flip side.
