While there is a danger in overstating the activity of evil in the world, the greater danger lies in underestimating it. Indeed, it is difficult to maintain credibility, and yet consider the possibility of the demonic — the possibility of “other world”. It is difficult to be respected as a rational thinker (in modern Western society), while embracing such a possibility. But I think it is irrational to rule out such possibilities. Moreover, if you accept the message of Christ as reflected in the gospels, you cannot deny that there is significant concern with evil and its personification in spirit form. I think that it is impossible to understand the Kingdom of light without reflecting upon the kingdom of darkness.
