I call that 'inner voice' intuition- it's my voice that I hear... as though I am speaking to myself, in a way that I will understand myself... sometimes reading, listening to music or looking at a picture will get that inner voice going and I will have personal revelations about anything and everything- But that is just me, talking to me, learning for myself, as you said, the Holy Spirit is a PERSON not a feeling/emotion/intuition...
My 'intuition' tells me, that this 'inner voice' is not what Shelby was talking about when it comes to HEARING the WORD or the Holy Spirit SPEAKING to you.... to talk to some else would imply that their are TWO distinct VOICES taking part of the CONVERSATION... one yours and the other... well I'm sure you get my point now
