We could just get on with our human logic if we decided that God did not exist and by virtue of that logic, we would be obligated to build the cleanest and most hallowed world possible for the salvation of our human logic. Where's your cell phone honey or baboo? Now, most of us our too logical to even think of emoting like that. It is just a cell phone.  This means we could consider our collective behavior accordingly without consideration of a prophecy that the world must end.  The tremendous technology in our hand bags of vast discovery make it obvious that the end cannot be man-made; that is if we have the time to even think or contemplate whether God exists. If the end  to the world is the result of human hands, human endeavor or the lack thereof, then God must exist and the word of God concerning human nature is true. The whales and other animals must know the Prince of peace.  Faith is a choice. Read Deuteronomy 8 and 11. An end to human existence as we know it is as much as man can achieve. It is a very particular endeavor of agreed conflict instead of cooperation. Your dog is able to understand you when you say "Kissy Kissy". Human beings have very sophisticated powers of communication. What have we decided today for the general quality of human life tomorrow?   The end could not be of human hands since we have too much brain power and time in our gifts of logic to think about  whether God exists. We buy soccer shoes when there is a 2 for 1 deal as opposed to buying one pair for the same price.  The end, if we are soo smart to argue about God, has to be the result of some natural disaster since our logic would predicate that we follow logically and collectively the simple wisdom of the word of God or Maslow's Hierarchy of needs. What does mankind need? They need water and air. This also demonstrates the shortsightedness  of man's wisdom to utilize technology to sustain man's existence and the various animals that remain dependent on his rationale to preserve the only habitat as we have it  for life. Jesus came that we might have life and life more abundantly.
