“We may also fitly remember that Satan has his miracles, which, though they are deceitful tricks rather than true powers, are such a sort as to mislead the simple-minded and untutored [Thes, 2:9-10] … Idolatry has been nourished by wonderful miracles, yet these are not sufficient to sanction the superstition either of magicians or of idolators.”

That writers do not always mean the same thing when treating of miracles is perfectly clear; because what may appear a miracle to the unlearned is to the better instructed only an effect produced by some unknown law hitherto unobserved. So that the idea of miracle is in some respect dependent upon the opinion of man. Much of this confusion has arisen from the definition of Miracle given in Hume's celebrated Essay, namely, that it is the "violation of a law of nature." Now a miracle is not necessarily a violation of any law of nature, and it involves no physical absurdity. As Brown well observes, "the laws of nature surely are not violated when a new antecedent is followed by a new consequent ; they are violated only when the antecedent, being exactly the same, a different consequent is the result;" so that a miracle has nothing in its nature inconsistent with our belief of the uniformity of nature. All that we see in a miracle is an effect which is new to our observation, and whose cause is concealed. The cause may be beyond the sphere of our observation, and would be thus beyond the familiar sphere of nature; but this does not make the event a violation of any law of nature. The limits of man's observation lie within very narrow boundaries, and it would be arrogance to suppose that the reach of man's power is to form the limits of the natural world. The universe offers daily proof of the existence of power of which we know nothing, but whose mighty agency nevertheless manifestly appears in the most familiar works of creation. And shall we deny the existence of this mighty energy simply because it manifests itself in delegated and feeble subordination to God's omnipotence?

Context: Art is born and takes hold wherever there is a timeless and insatiable longing for the spiritual, for the ideal: that longing which draws people to art. Modern art has taken the wrong turn in abandoning the search for the meaning of existence in order to affirm the value of the individual for his own sake. What purports to be art begins to looks like an eccentric occupation for suspect characters who maintain that any personalised action is of intrinsic value simply as a display of self-will. But in an artistic creation the personality does not assert itself it serves another, higher and communal idea. The artist is always the servant, and is perpetually trying to pay for the gift that has been given to him as if by a miracle. Modern man, however, does not want to make any sacrifice, even though true affirmation of the self can only be expressed in sacrifice. We are gradually forgetting about this, and at the same time, inevitably, losing all sense of human calling.
