While theoretically a person may block God out, logically there will be a breakdown because ultimately all enunciation implies a moral doctrine of some kind. And if that moral doctrine is not absolute then the definer himself becomes undefined. That's what we are living with - an undefined definer giving us definitions for our course, and we are being trapped in the quicksand of the absence of objective truth.
Trust that your soul has a plan, and even if you can't see it completely, know that everything will unfold as it is meant to.
