Miracles must have some special religious significance?

[tonychanyt]

Let's define a miracle as an extraordinary and highly improbable event or phenomenon that occurs against the odds or expectations of natural physical laws. This is a secular definition that does not mention any supernatural intervention.
Satan can perform miracles. Satan from the vertical realm can produce a disruptive and instantaneous effect within a spacetime situation in the horizontal realm. An atheist can observe the results of this spacetime interruption.
Dr Alvin Plantinga said:

Suppose, say on the moon, on the other side of the moon, … a rabbit suddenly appears, and then suddenly disappears, and then changes into something else, and the like. That would not be a miracle.

I wouldn't dismiss it so quickly. It is potentially a miracle according to the above definition.

A miracle has to have some kind of religious significance as well. So, the miracles Jesus did. One thinks the point of these miracles was to show that his message was really correct, really was from God. … So, the first thing about miracles is that it has to have some special religious significance.

John 2:11 called these kinds of miracles signs. I agree that nearly all miracles in the Bible carry significant religious meaning. The miracles recorded in the Bible were deeply embedded within a theological and religious framework, as they were typically presented as acts of God (or divine agents like angels or prophets) that revealed His power, authority, character, and purposes.
1 Kings 17:2–6 described a miraculous event with ravens feeding Elijah during a drought. From a historical perspective, it was a miracle to sustain Elijah. From a utilitarian standpoint, the religious significance was secondary. Outside of the Bible, I can accept a secular definition of miracle. For example, Satan can perform a miracle for whatever purpose he has in mind.
If Dr Plantinga wishes to engage his argument with atheists, he needs to accept a secular definition. Otherwise, his arguments would only appeal to Christians who may not need convincing.
