Experiencing grace involves the expansion of consciousness of self to all of one's surroundings as an unbroken whole, a consciousness of awe from which negative mindstates are absent, from which healing and groundedness result. For these reasons grace has long been deemed "amazing."
The function of faith is not to reduce mystery to rational clarity, but to integrate the unknown and the known together in a living whole, in which we are more and more able to transcend the limitations of our external self.
