It is fairly common to hear atheists say that miracles violate the laws of nature. It is more irksome when Christians actually repeat that claim as if it were the right and valid definition of a miracle rather than an opponent's slur.
Nature and the Miracles of Healing
Most miracles recorded in the New Testament are miracles of healing. Such a miracle is not remotely about "violating" the laws of nature. Instead of being anti-nature, the healing miracles are restorative, putting nature right again. The healing miracles and resurrections are also, without exception, a benefit to those who receive them. They are not random or capricious acts, but acts of blessing. The power at work here is not opposed to the natural order but a source of renewal for it, returning it to its originally right state or healthy pattern.
The most common type of a miracle recorded, then, is a restoration of nature. In a healing miracle, God acts to bless people by restoring their natural human bodies to full natural health. That is hardly the transgression of the law of nature proclaimed by Hume and company.
