No problem HB. I've been thinking on this some as well.
This verse came to mind:
But those things which proceed out of the mouth come forth from the heart; and they defile the man. For out of the heart proceed evil thoughts, murders, adulteries, fornications, thefts, false witness, blasphemies: These are the things which defile a man: but to eat with unwashen hands defileth not a man.
(Mat 15:18-20 KJV)
You could say that the heart of every unsaved person is like an abyss.
Jesus didn't mince any words when he described the fall of man.
In a historical context it would be reasonable to say that the tower of Babel and Babylon came from the abyss because they came from the hearts of fallen men. The source of Paganism. Nothing of paganism has come from the Lord.
