It has always occurred to my mind that many difficulties touching Miracles might be reconciled, if men would only take the trouble to agree upon the nature of the phenomenon which they call Miracle. 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?

Miracles are very often thought of, both by those who believe in them and by those who do not, as events, or purported events, that contradict the laws of nature and that therefore cannot be explained by science or reason. But this is not at all what the Bible means by a miracle, as any Biblical scholar will tell you. “The laws of nature” is a modern scientific concept. The Bible knows nothing about nature, let alone the laws of nature.

A miracle is a violation of the laws of nature; and as a firm and unalterable experience has established these laws, the proof against a miracle, from the very nature of the fact, is as entire as any argument from experience as can be imagined.

A miracle is a violation of the laws of nature; and because firm and unalterable experience has established these laws, the case against a miracle is — just because it is a miracle — as complete as any argument from experience can possibly be imagined to be. Why is it more than merely probable that all men must die, that lead cannot when not supported remain suspended in the air, that fire consumes wood and is extinguished by water, unless it is that these events are found agreeable to the laws of nature, and for things to go differently there would have to be a violation of those laws, or in other words a miracle? Nothing is counted as a
miracle if it ever happens in the common course of nature. When a man who seems to be in good health suddenly dies, this isn't a miracle; because such a kind of death, though more unusual than any other, has yet often been observed
to happen. But a dead man’s coming to life would be a miracle, because that has never been observed in any age or country. So there must be a uniform experience against every miraculous event, because otherwise the event wouldn't count as a ‘miracle’. And as a uniform experience amounts to a proof, we have here a direct and full proof against the existence of any miracle, just because it’s a miracle; and
such a proof can’t be destroyed or the miracle made credible except by an opposite proof that is even stronger.

This clearly leads us to a general maxim that deserves of
our attention:

No testimony is sufficient to establish a miracle unless it is of such a kind that its falsehood would be more miraculous than the fact that it tries to establish. And even in that case there is a mutual destruction of
arguments, and the stronger one only gives us an assurance suitable to the force that remains to it after the force needed to cancel the other has been
subtracted.

Miracles may be, for anything we know to the contrary, phenomena of a higher order of God's laws, superior to, and, under certain conditions, controlling the inferior order known to us as the ordinary laws of nature.

Miracles are not the intercession of an external, divine agency in violoation of the laws of nature. A miracles is something impossible from an old understanding of reality, and possible from a new one.

That miracles are things in themselves possible, must be allowed so long as it is evident that there is in nature a power equal to the working of them. And certainly the power, principle, or being, by whatever name it be denominated, which produced the universe, and established the laws of it, is fully equal to any occasional departures from them. The object and use of those miracles on which the christian religion is founded, is also maintained to be consonant to the object and use of the general system of nature, viz. the production of happiness. We have nothing, therefore to do, but to examine, by the known rules of estimating the value of testimony whether there be reason to think that such miracles have been wrought, or whether the evidence of Christianity, or of the christian history, does not stand upon as good ground as that of any other history whatever.

Miracles occur naturally as expressions of love. 2The real miracle is the love that inspires them. 3In this sense, everything that comes from love is a miracle.

Miracles, by our very definition of the term, are virtually impossible events. [...] We would call a miracle an event that violates the way nature always, or almost always, works so as to make the event virtually, if not actually, impossible. The chances of a miracle occurring are infinitesimal. If that were not the case it would not be a miracle, just something weird that happened. And weird things happen all the time.

If we are to suppose a miracle to be something so entirely out of the course of what is called nature, that she must go out of that course to accomplish it, and we see an account given of such a miracle by the person who said he saw it, it raises a question in the mind very easily decided, which is,-Is it more probably that nature should go out of her course, or that man should tell a lie? We have never seen, in our time, nature go out of her course; but we have good reason to believe that millions of lies have been told in the same time; it is, therefore, at least millions to one, that the reporter of a miracle tells a lie.

Miracle is simply the religious name for event. Every event, even the most natural and usual, becomes a miracle, as soon as the religious view of it can be the dominant. To me all is miracle.

(I know, it's a poem but oh well).
Why! who makes much of a miracle?
As to me, I know of nothing else but miracles,
Whether I walk the streets of Manhattan,
Or dart my sight over the roofs of houses toward the sky,
Or wade with naked feet along the beach, just in the edge of the
water,
Or stand under trees in the woods,
Or talk by day with any one I love — or sleep in the bed at night with
any one I love,
Or sit at table at dinner with my mother,
Or look at strangers opposite me riding in the car,
Or watch honey-bees busy around the hive, of a summer forenoon,
Or animals feeding in the fields,
Or birds — or the wonderfulness of insects in the air,
Or the wonderfulness of the sun-down — or of stars shining so quiet
and bright,
Or the exquisite, delicate, thin curve of the new moon in spring;
Or whether I go among those I like best, and that like me best — mechanics, boatmen, farmers,
Or among the savans — or to the soiree — or to the opera,
Or stand a long while looking at the movements of machinery,
Or behold children at their sports,
Or the admirable sight of the perfect old man, or the perfect old
woman,
Or the sick in hospitals, or the dead carried to burial,
Or my own eyes and figure in the glass;
These, with the rest, one and all, are to me miracles,
The whole referring — yet each distinct, and in its place.

To me, every hour of the light and dark is a miracle,
Every cubic inch of space is a miracle,
Every square yard of the surface of the earth is spread with the
same,
Every foot of the interior swarms with the same;
Every spear of grass — the frames, limbs, organs, of men and women,
and all that concerns them,
All these to me are unspeakably perfect miracles.

To me the sea is a continual miracle;
The fishes that swim — the rocks — the motion of the waves — the ships,
with men in them,
What stranger miracles are there?

Even doctors, I found, often used the word "miracle" in describing what happened when a patient suddenly got well after taking a natural remedy. The word "miracle" is defined in dictionaries as "a wonder, a marvel," as well as an act or happening that departs from the laws of nature. Thus, when a person recovers after taking a natural substance, the event is so incongruous with conventional medical expectations that the first words of surprise and overwhelming gratitude are typically: "It’s a miracle cure." We often say the same thing about conventional treatments that amaze us.

If we define a miracle as an effect of which the cause is unknown to us, then we make our ignorance the source of miracles! and the universe itself would be a standing miracle. A miracle might be perhaps defined more exactly as an effect which is not the consequence or effect of any known laws of nature.
