Psalm 28

To You I will cry, O Lord my Rock:
Do not be silent to me,
Lest, if You are silent to me,
I become like those who go down to the pit...
Blessed be the Lord,
Because He has heard the voice of my supplications!
7 The Lord is my strength and my shield;
My heart trusted in Him, and I am helped;
Therefore my heart greatly rejoices,
And with my song I will praise Him. vv. 1,6-7

This is another Psalm of David while facing a time of trouble.  He starts his prayer saying to God he'll cry.  A cry is a natural utterance for sorrow and David goes to God to cry.  How often when people are in trouble or distress or just need a good cry do they turn first to friends, family, the governments, a sappy movie, religious organizations, food and lastly (and maybe) to God.  That's not to say that it's wrong to torn to others for help, but to turn to God first and foremost presenting your requests, angers, feelings, etc.  Even in verse seven, the sequence of events is that David first trusted and then was helped.  This psalm starts off with David's prayer of calling out to the Lord and ends with how God heard and answered him.  
Who do you usually go to first when in times of trouble?  David also cries to the Lord to not be silent, wanting His answer.  That can be hard for us too, waiting on God's answer and cause us to turn elsewhere.  What is something you're facing right now that you haven't "cried" to the Lord about yet?  Or not trusted Him in patience for His answer?
