The secular faithful believe that multiple wills shape our reality, but this time it’s not the wills of various gods. It’s the wills of various individuals, based on what they want, what they think is morally desirable, or whatever seems compassionate at the moment in a specific case. They make universal law based on idiosyncratic circumstance. Throughout history we find lots of great minds who throughout their life did everything to get people way from God trying to let them believe that god did not exist, but they themselves got a funeral in one of the main churches from Christendom, as to say to the world "you may now not believe any more in god, but I shall try to get an other life by letting myself buried the Christian way."
Though many things may be very difficult to proof that does not mean that they would not exist. Also feelings and experiences are difficult to proof, though the results of a God-Being in our life is something what many feel. One thing is for sure: "If God does not exist, then everything is permitted". In the transcendent reality we can not see nor fully understand God but somehow looking around us and listening to our inner feeling each person should be able to come to recognise the Supreme Power and to understand that reality is shaped by a Power beyond us.
