When we set out to hear God's voice, we do not listen as though it will come from somewhere above us or in the room around us. It comes to us from within, from the heart, the dwelling place of God. Now, most of us haven't been trained in this, and it's going to take a little practice "tuning in" to all that's going on in there. And there's a lot going on in there, by the way. Many things are trying to play upon the beautiful instrument of the heart. Advertisers are constantly trying to pull on your heartstrings. So is your boss. The devil is a master at manipulating the heart. So are many people—though they would never admit that is what they are doing. How will you know what is compelling you? "Who can map out the various forces at play in one soul?" asked Augustine, a man who was the first to write out the story of listening to his heart. "Man is a great depth, O Lord ... but the hairs of his head are easier by far to count than ... the movements of his heart."
This can be distressing at times. All sorts of awful things can seem to issue from your heart—anger, lust, fear, petty jealousies. If you think it's you, a reflection of what's really going on in your heart, it will disable you. It could stop your journey dead in its tracks. What you've encountered is either the voice of your flesh or an attempt of the Enemy to distress you by throwing all sorts of thoughts your way and blaming you for it. You must proceed on this assumption: your heart is good.
