1 Corinthians 2:12-13

Now we have received, not the spirit of the world, but the (Holy) Spirit who is from God, so that we may know and understand the things freely given to us by God.  We also speak of these things, not in words taught or supplied by human wisdom, but in those taught by the Spirit, combining and interpreting spiritual thoughts with spiritual words (for those being guided by the Holy Spirit).

The Holy Spirit is our guide and teaches and reveals things that we could not know without His help.  The Holy Spirit has a definite purpose of helping us fulfill our call on this earth.  We must stay sensitive to the inner voice and respond quickly to direction.  God is more able to move in our lives the more available we make ourselves to guidance.
