Why not tap into someone that knows everything?

Our Heavenly Father literally knows everything.  God created the heavens and the earth.  Our God knew us before the foundation of the world.  It says in Ephesians 1:3-4 (NIV) “3 Praise be to the God and Father of our Lord Jesus Christ, who has blessed us in the heavenly realms with every spiritual blessing in Christ. 4 For he chose us in him before the creation of the world to be holy and blameless in his sight.”  Our God already has everything figured out.  Why don't we tap into his wisdom through prayer and faith, and get supernatural wisdom about the direction for our lives.  Why not try to fit into God's plan for our life?  When we do we will find that we become more happy, joyful, fulfilled and have more peace in our life.
