Ephesians 1:17 

(I always pray) that the God of our Lord Jesus Christ, the Father of glory, may grant you a spirit of wisdom and of revelation (that gives you a deep and personal and intimate insight) into the true knowledge of Him (for we know the Father through the Son).

The more insight and knowledge that we have into God, the greater our trust will be.  The greater the confidence, the more often we will turn to Him for guidance in our lives.  God will then prove Himself a potent force for good in our lives.  The flesh and all the worldly wisdom do not match one word from God.
