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.

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.

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.

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.

A word about the title--"Nature's Miracles." Some may claim that it is unscientific to speak of the operations of nature as "miracles." But the point of the title lies in the paradox of finding so many wonderful things--as wonderful as any miracle that was ever recorded--subservient to the rule of law. "But," you say, "a miracle does not come under any rule of law." Ah! are you sure of that? It is true that we may not understand the law that the so-called miracle comes under, but the Author of all natural law does.

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.

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.

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, contrary to popular belief, do not just happen. A miracle is the achievement of the impossible, and it is only when we put aside out greed, anger, pride and prejudice so that our minds are open and ready to accept it, that a miracle can occur.

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.

A miracle is when the whole is greater than the sum of its parts. A miracle is when one plus one equals a thousand.

A miracle is a beginning and an ending. 2It thus abolishes time. 3It is always an affirmation of rebirth, which seems to go back but really goes forward. 4It undoes the past in the present, and thus releases the future.

A Course in Miracles defines “miracle” as a divine healing of human perception; a change of mind that shifts perception from fear and guilt to love and forgiveness. This higher level of perception heals the mind from pain and suffering and places it in the service of spirit.
