On the one hand, there a Christian sub-culture obsessed with demon possession and “deliverance” ministries. According to this worldview, there are generational demons, poverty demons, sickness demons and even demons that make one infertile.
The key to a powerful Christian ministry is to identify the particular demon involved and cast it out in Jesus’ name. T.B. Joshua is perhaps the most infamous adherent to this model of ministry.
On the other hand, there is a Christian sub-culture that dismisses the supernatural and the spirit-world.
According to this worldview, there is a rational, cause-and-effect, scientific explanation for everything that happens. Demon-possession was simply the uniformed explanation for illnesses in Bible times that were not understood. We know better now.
