If you answered my three simple questions your statements would be more convincing…
- Do you agree that miracles occur frequently
Extremely frequently. The Holy Eucharist is a most astonishing miracle that is renewed every day in many places around the world.
and that very often they cure diseases and deformities?
No, while they do occur, physical miracles are rare. The Catholic Church is quite explicit about that. Even in the long history of Lourdes, for example, there are only some 60+ confirmed miracle healings, even though the claims run into the thousands or even ten thousands (regardless of what you think of Lourdes and miracles in general, the point is that miracles, certainly confirmable ones, are considered rare).
As for God helping us with physical needs, I don’t see why this cannot occur along natural channels rather than by supernatural means (even though that does happen, though very rarely). For example, upon prayer God can direct us to a doctor who can help us effectively with sickness, instead of healing us directly.
- Do miracles ever occur to prevent accidents
Perhaps, but (upon prayer or not) God can move souls of people involved in a chain of events in order to prevent accidents without a physical miracle. I had discussed that earlier in the thread.
There is no evidence for that, no. Science can quite well predict the general frequency of earthquakes in certain spots around the globe (e.g. in the Ring of Fire forming the border of the Pacific tectonic plate), and there is no reason to think God interferes – nor for the better nor for the worse.
The Haiti earthquake was predicted (not the precise day, of course, but it was considered overdue before it happened), including the approximate magnitude (around 7 on the Richter scale).
In the natural order, God appears to intervene rarely, at least in a measurable way. This is even logically necessary, otherwise we would not know what to expect from our physical world. Imagine stepping into an airplane without predictable laws of nature …
God made the world as it is. He foresaw all the consequences of the laws of nature, and if bad things happen, good can come from that (this is classical Catholic theology, by the way). Obviously, for reasons that God knows, God did not create a world in which suffering is impossible or even prevented.
- Are miracles restricted to believers and those who pray for a miracle?
It appears not. There are some amazing conversion stories based on miracles that were not asked for.
