Often times, we think that God will speak to us in a loud, audible voice in our head. That of course, is not altogether true. God speaks to us through Pastors, friends, family, etc. The misconception is that we are alone in hearing God's voice, that the only time God can speak to us is "in our minds".
Please visit this site to read what Tim Burns has to say about this topic. He talks about how we need to prepare ourselves (spiritual disciplines) before we even have the ability to hear the voice of God.
