All in Knowing God’s Voice

When we hear the Lord speaking to us what does that sound like? What is it about His voice that convinces us that we are actually speaking with Him, and later, when He speaks again how is it that we recognize His voice as being the same? We read in scripture of God speaking, we imagine Him speaking before He talks to us the first time, and we know somehow that we will knowHim when he does, but how is that? Do I hear Him as you hear Him, as someone else hears Him? If He whispers, shouts, or speaks in a normal tone how do we recognize that it is the same person; is it just like how we know our earthly father’s voice? The voice of God… so mysterious… so indescribable, and yet so distinct and certain. How does our Father sound to us?
