A miracle is an event which creates faith. That is the purpose and nature of miracles. Frauds deceive. An event which creates faith does not deceive: therefore it is not a fraud, but a miracle.
The genuine realist, if he is an unbeliever, will always find strength and ability to disbelieve in the miraculous, and if he is confronted with a miracle as an irrefutable fact he would rather disbelieve his own senses than admit the miraculous also.
Life and the world, or whatever we call that which we are and feel, is an astonishing thing. The mist of familiarity obscures from us the wonder of our being. We are struck with admiration at some of its transient modifications, but it is itself the great miracle.
There is nothing that God hath established in a constant course of nature, and which therefore is done every day, but would seem a Miracle, and exercise our admiration, if it were done but once.
I can believe a miracle because I can raise my own arm. I can believe a miracle because I can remember. I can believe it because I can speak and be understood by you.
We buy books, we go to gyms, we expend a lot of brain power on trying to hold back time, when we should be celebrating the miracle of being here in this world.
