In Mark 4:11-12 (KJV) Jesus says all these things are done in parables, so some although ever seeing never perceive, and although ever hearing never understand, or else the would turn and be forgiven.
Genesis tells you the the "FIRMAMENT" separates the "waters above" from the "waters below".
Revelation 17:15 tells you the waters, where the PROSTITUTE sits, stands for people, multitudes, nations and languages.
So who separates the people (waters) "above" from the people (waters) "below"?
What is the Living Water Jesus promised?
