magicmiles, how's it going? I hope you are doing well since our last chat. I saw that you didn't have anything further on this topic at this time, but I would like to throw my two cents in, and possibly give you something to muse on.
I did have a few experiences as a believer that, at the time, I took as being an experience of God.
I remember during one particular time of struggle, I asked for a sign that God was listening. It immediately started raining, as in simultaneously with the end of the request. It seemed quite impressive at the time, and I suppose that you could say that I had a gut instinct about God at this time.
However, as I became more and more confident in my skepticism, it occurred to me that perhaps such things are merely the result of coincidence. After all, coincidental events are often considered to have a causal relationship, even if there is not necessarily any reason to believe so.
Additionally, I could not help but notice that members of different faiths all claimed to have similar types of experiences. It seemed to me odd that such an experience could be considered a validation of my faith, but not equally validating of others faith. It seemed that the standard for faith ought to be consistent all around, and that either all of those people of different religion have valid belief in their God, or none of them do, or just one of them does. The last option seems the least likely to me, and the second option most likely.
Gut instincts can certainly be wrong in other ways. In my case, it's usually in regards to my love life. I certainly had a “gut instinct” about my now ex wife. Turns out, I misread it. I took it to mean “Hey, you might like this one!”” when what it really said was “Hey, you might want to run”. Our intuition can be useful at times, but not as a tool to override our reason.
Therefore, I have since come to believe that while people certainly do experience "gut instinct" type feelings regarding God, that such feelings, in my view, do not automatically demonstrate any actual relationship with or evidence of the divine. To me, there are merely indicative of a sense of transcendence, a state of overwhelming awe, that is, to me anyways, wrongly attributed to any number of deities, spirits, angels, demons, or Hobbits (even if it's one of the awesome ones, like Sam, I still can't buy it). I would merely consider it a state of awe and admiration for something even as we humbly admit that we don't understand it.
