Because Grace is the connected/integrated state of the cosmos as quantum mechanics tells us,  and as the temporal universe is an extrapolation of the primary quantum reality simply with time and space much more apparent…but actually still connected and integrated….that reality hence is aligned with the primary reality of the entire cosmos….and every advancement and every paradigm change is a further awakening to that most basic reality. Finally, man’s actual species designation is homo sapiens, wise and discerning man. Grace being the pinnacle concept and experience pointed at and described by all of the world’s major wisdom traditions, so Man is in the process of awakening to himself as the planet’s highest manifestation of wisdom and discerning self awareness. When you see the logical progression of this is when you can begin to truly understand it.
