Commit everything to God

In Psalm 119:26 we see that God answers those who pray to Him, making known all their concerns, hopes, fears, and sorrows.  Why does the Lord desire that we unburden ourselves to Him, telling Him all that is happening to us?  He knows all things.  He knows us better than we know ourselves.  It is not for His benefit, but for ours.  It helps us to believe that God is concerned about our every desire and need.  It is an acknowledgment of His sovereignty, committing everything in our lives to the direction of His providence.  Acquainting the Lord with all our desires in prayer is an act of faith and dependence that pleases Him and blesses us.
