like killing babies or betraying Jesus who was chosen on the same non date (time didn't exist before creation) to die
in a fairly nasty fashion and thereby appease the righteous wrath of himself and his fellow Trinitarians by paying a penalty as a substitute for all future sins (of believers?)
what is necessary and a very important change for us today and the future is our conscience, and this requires global consciousness necessary for our long term needs and survival, we need a faith that will compel us to unite to address the problems of survival,

planets or, develope a
system that will protect us, the natural calamities
like floods, typhoons, sub zero temperatures, will become our big problem
in the future, so we need a religion that will guide our conscience from simplistic self survival towards a more holistic view of reality.Our oneness with ourselves and Him is the primary tenets or doctrines of this religion.
