Let us remember that every worldview-not just Christianity's-must give an explanation or an answer for evil and suffering...this is not just a problem distinctive to Christianity. It will not do for the challenger just to raise the question. This problem of evil is one to which we all must offer an answer, regardless of the belief system to which we subscribe.
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.
