I don't know if you're familiar with the concepts of a fasttrachk and a slow track neurologically speaking. The slow track is primarily processed in the left part of the brain and the content of this track is what we understand as conscious thought, our will, our capacity to make decisions. The fast track is primarily located in the right part of the brain and consists of our perception of others, atmospheres, emotions, and also to a large part our immediate response to anything unforseen.
The difference between the two tracks is responsible for the fact that to change our personality, esp. those parts of it that is 'dysfunctional', information isn't sufficient. And most often, I can try and engage my will as much as I like, it will most of the times easily be overtaken by fast track processes...
It seems to me that a part of your distinction between the slow thinking in words, and a much faster just pouring out to God whatever is within you, hoping that words will follow, has got something to do with this difference...?
