CaveA miracle occurs when the supernatural order directly intervenes in the natural order. Through a modern abuse of language, the latter term has come to connote rationality, and the former irrationality.  However, there is nothing irrational in the nature of a miracle.  It is logical that the possibility of direct contact between the natural and supernatural orders must be realized, given that they are only separate in appearance. If the natural order was truly divorced from the supernatural, and therefore there was no possibility of a miracle, then it would have no existence whatsoever, because it would have no principle or root. If the inverse is true, then miracles are a necessity by the very fact that they are possible. The bolt of lightning, with its suddenness and blinding whiteness reflects the principle of the miracle in the natural order proper.
