The question of deliverance from demons has always been attested to in the Bible and throughout the ages What the gentleman is inferring to the lady is that she and Christians need deliverance from demons too. As far as I have studied Christians can be oppressed by demons but never possessed by demons. Me do think upon John 1: 5 ( And the light shineth in darkness and the darkness comprehended it not ) some put special emphasis on the passage of scripture. Meaning that darkness fled for its life once exposed to the light.
