Many times when we (Christians) expect to hear from God, we think that He will speak in an audible voice and he will say "Mary! stay away from him, or don't do that!" But most times, God speaks to us in that small still voice. God is spirit, so He speaks to our spirit and our spirit speaks to us. We can hear from God either through a word of knowledge, where we just know something, and it doesn't make sense that we know it. Other times He can speak through our spirit and we hear it in a first person voice, that we often think that we are speaking to ourselves, not knowing that it is God speaking to us.
