Observed truth or truth we discover, is ultimately inadequate to affect absolute certainty within man. Having no deeper foundation other than our own fallible faculties, our beliefs must deliver a standing invitation to all competing ideas until all possibilities are exhausted. If, then, our beliefs stand, they can only hold certainty in the sense of having withstood all other ideas our current day and age can muster and for which we are able to understand. Thus, our beliefs can only hold a current temporary certainty while holding a respect for such a time in the future that mankind is able to obtain a greater understanding of those beliefs. Thus, absolute certainty can never be reached by mankind. It has the effect of silencing the free exchange of ideas and creating a tyranny upon other men who hold differing beliefs.
Truth, as a Being with person-hood, is entirely in the position to produce a greater degree of certainty within man than he could reach alone. For Truth, having personality, could relate with man, instruct, and cleanse man of error he could not have eliminated on his own. That is not to say that man would then have an infallible understanding of the truth. The best he could do is present to others a representation of this Truth-Being or a representation of some external truth the Being has communicated. The representation would still be subject to the fallible faculties of man and therefore must deliver the same standing invitation to other representations. Otherwise, tyranny will result. Furthermore, whatever refined beliefs man contains inside himself must be held in a progressive truth-seeking manner with a respect for some newer revelation communicated by this Truth-Being in the future. For it is absurd to believe that man has perfect understanding of truth the first time it is communicated to him.
Therefore, the only difference realized by man, either in truth discovered solely by man or truth received from this Truth-Being, is the deeper ground on which he stands when receiving communication from this Being. Those who criticize representations of this Being without standing in deeper ground themselves will compete with any self-authenticating witness this Being has produced inside the man standing on the deeper ground and will, thus, be only marginally effectual in an argument. Effectiveness can be obtained either by developing a greater understanding of the representations or moving onto deeper ground.
