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.
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.
The believers in miracles accept them (rightly or wrongly) because they have evidence for them. The disbelievers in miracles deny them (rightly or wrongly) because they have a doctrine against them.
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.
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.
Rarely do we realize that we are in the midst of the extraordinary. Miracles occur all around us, signs from God show us the way, angels plead to be heard, but we pay little attention to them because we have been taught that we must follow certain formulas and rules if we want to find God. We do not realize that God is wherever we allow Him/Her to enter.
