Degrees of Natural Faith

Natural faith, which is always the same in its nature or essence, exists in different degrees. And this is so truly and distinctly the case, that we frequently employ different names as expressive of the different degrees of credence, which we yield. Differences in the degree of belief depend chiefly upon differences in the evidence, which is presented before the mind. And as the evidence in its different kinds is greater or less, we are in the habit of designating the resulting belief by names appropriate to its strength, such as presumption, slight or strong presumption, probability, low or high probability, and certainty. The same inward consciousness, which teaches us the nature of faith, indicates also the degree of it. And in accordance with this general view, which is scripturally as well as philosophically correct, we very frequently and very properly speak of a person’s faith in reference to its degree; describing one person as a man of strong faith and another as a man of weak or small faith, or by some other epithets intermediate in signification.
