A further thought: When one becomes spiritually deluded (known as 'prelest' in Russian or 'plani' in Greek), I have read that they can become demonic. I believe this is what has happened to Benny Hinn in his rantings, ravings and self annointed holiness, and let us remember that the demons can fool with miracles as well.
That is why I am very sad for his soul.
Briefly, the difference between "general prelest" and prelest in the particular sense of the word can, on the basis of the above. be expressed thus. General prelest is forgetting and not noticing one's sinfulness. That which we call prelest proper is attributing to oneself righteousness when it does not actually exist. If a man thinks he is righteous, then his righteousness is not divine, but diabolical, foreign to the grace of God and to humility. One should recall the famous saying of Abba Poemen the Great: "I prefer a man who sins and repents to one who does not sin and does not repent. The first has good thoughts, for he admits that he is sinful. But the second has false, soul-destroying thoughts, for he imagines himself to be righteous" (Bp. Ignatius, Patericon, 75).
