I have seen by personal experience that miracles are real and can't be explained by our natural world.
What I can't get my brain around is ? do miracles happen because of prayer ? do we have account with God in his bag of miracles ? are we given a certain amount a miracles in our life time ? can you invoke miracles ? ...
Yes, I have seen myself miracles, but, in the last 10 years they have been non existent.
I expect that in this context, "miracle" means an act of God that is meant to be an obvious stand out to the casual observer. His normal course with me, however, has been to guide and provide in such a way that it might appear "ordinary" under the casual glance. It's only after you look at the particular circumstances that you get the idea there is something in this not explainable by chance; in fact, you see a pattern that becomes obvious in hindsight.
Big, flashy miracles are not the norm. In the first place, since God designed the normal order of things, it seems natural that He would prefer to work according to that pattern. Departures from the natural order, which apparently only occurred a few times in history, tend to generate a lot of attention and excitement around the folks who are associated with them. When those folks have been given a particular message which demands such attention, this is appropriate; but in any other situation, it would make them a target of envy; and, it would encourage superstition. Think "cargo cult".
Just watch for the providence of God, which sometimes is flashy and obvious, but most of the time is quiet and easier to overlook. But it always is effective.
