CLAIM: The psalmist prophesies about the fullness of sin that will be expressed by those who will be given over to abominable sin. This will occur in a time of a great falling away and oppression of God’s people.
This interpretation comes it seems from that AW Pink book in the study of the anti christ (see a further discussion here) where he lists many supposed names of the coming “anti christ”, one of them being “The Fool” (Psalm 14:1). This is tantamount to attempting to take every horrible attribute in the entire scrope of the Book and rolling this into one huge super villian in the end times. It may work good in stories, but there is no exegetical reason to do so.
The need to take every title, especially such as this, and apply it to one end time evil is something, despite the Bible never introduces, as it is seen. It isn’t that there haven’t been and wont be demonically possessed and inspired men who attempt to destroy the world through the powers of the devil, but the great conflict that is seen as coming by most futurists is seen as accomplished in the analysis of Daniel (see here).
As with other titles from the book of Psalms, it is merely the work of fantasy of a man who was known to have been involved in a gnostic cult, and should not be considered authoritative.
These various titles for this proposed horrible evil are all descriptors of the great wickedness man is without God. Let none of them ever describe us, who are the children of light. That is the message, and it is for our day as well as any day to come.
