Tammy,
I know you are directing your post to believers. My problem is that when you think you need some "spirit" to tell you what to do or inform you there is really no way to objectively verify the accuracy of your information. That's the problem with intuition. Intuition can be right but it is often wrong and you don't know until you start dealing with a particular decision whether it was good or bad.
As a JW I was always presented with these experiences where people made a decision after praying and it proved to be the right course. OTOH you don't hear the horrible consequences when people pray and it turns out wrong. Usually, the person is blamed for not REALLY listening to the "spirit".
What works for me is to gather as much information as the problem merits and time permits. Then I make a decision. It is usually adequate but sometimes failure results. There is no evidence that prayer adds anything to the situation. However, it may be a useful heuristic that opens a person up to more possibilities. Watiing, when you have to make a decision can be very useful to get things in perspective. Sometimes time alone will make the decision for you. Prayer and listening for inner cues may help a person pass time until their more rational nature takes over.
I use a technique where I set up an x and a y axis to represent two possible variables each with two polar opposite outcomes. I then fill in each quadrant with the likely outcomes. It works as well for me as a dialogue with a fabricated person that I imagine to be God.
I didn't mean to steer the thread. I continue to look for unambiguous and extraordinay proof for the extraordinay claims of any religion.
The subtlety of the spirit's voice is about as persuasive as Christ's invisible presense in 1914.
