4What are demons? How do they gain entry into people's lives? Do Christians ever need deliverance from demons? In this practical, biblically based handbook, Derek Prince answers these and many other vital questions. If you are struggling with problems that never seem to go away, has it ever occurred to you that demons may be at work? 'Some Christians claim they are automatically protected from demonic attack by the blood of Jesus. God does indeed offer us total protection through the blood. But . . . this provision depends on our meeting His conditions.' Derek Prince points out that 'Jesus never sent anyone out to preach the Gospel without specifically instructing and equipping them to take action against demons in the same way that He Himself did.' If this is not true today, Derek Prince asks, 'Who has changed? Jesus? The demons? The Church?'
