Can't prove the supernatural God

[SteveII]

The difference between supernatural cause and a natural cause would be the properties of the efficient cause. Properties of a natural efficient cause include physical, governed by the laws of physics, repeatedly observed,  etc. Properties of a supernatural efficient cause would include non-physical, not bound by the laws of physics, powerful enough to act on the natural world. Added to that is the reasonable assumption that there is a purpose for the act. 

Can you give an example of something that has a material cause and not an efficient cause? Even better, an example that might otherwise be considered a miracle by someone at some time.

So, your position seems to be that what we call miracles have naturalistic explanations that we just don't understand yet?  

1) Isn't that an argument from ignorance? 
2) Under that reasoning, why don't we see more of these 'miracles' if it is just a matter of misunderstanding the cause? The rarity of a miracle actually supports the premise that miracles happen. 
3) If you zero in on a particular miracle example, there are often circumstances that make the 'heretofore unknown natural causes' just at the right moment and in the right context ridiculously unlikely. 
4) Whether a miracle happened or not is a probabilistic question. The more evidence and context clues the higher the probability.

1. No. He did not claim that miracles have naturalistic explanations we just don't understand yet, he pointed out that there's no way to rule a natural cause out.
2. So if they didn't happen at all, that would be proof positive that they're real, and if they happened all the time, that would show they're not real! Seriously, I don't think you thought that through at all.
3. People have very bad intuition when it comes to probability. Incredibly unlikely things do and MUST happen, frequently. The odds of a given Bridge hand are hundreds of billions to one, but you can deal Bridge hands all day long. As they say, the odds of an event that has already happened are 1:1. I don't think either of us are well equipped to determine what is so ridiculously unlikely that a supernatural intervention is a more plausible explanation than coincidence.
4) The more it stands up to serious scrutiny, the higher the probability. And claimed miracles have a terrible track record for standing up to scrutiny.

Unless you have one example of such?

1. I concede that point. Rob did not make an argument from ignorance.
2. If you reason that event x may look like a miracle but is really just natural causes we don't understand, isn't it reasonable to ask why we don't see event x happen more often. By your own argument in #3, improbable things happen with regularity. 
3. I don't disagree with you comments on probability. However, I still contend that context and timing have weight and, depending on the circumstances, they can make heretofore unknown naturalistic causes less and less likely until a potential naturalistic cause approaches 0%.  (see my example from Matthew 9)
4. I think you are right for a lot of events that happen today. I think that claims of miracles are way more numerous than the evidence supports. However, for a variety of reasons, I choose to believe the content of the NT, while perhaps not 100% historically accurate, it is largely accurate including the events surrounding Christ and his claims. I am sure you have reasons to believe otherwise. I don't think either of us is irrational.
