Psalm 139:23-24
Search me, O God, and know my heart;
Try me, and know my anxieties;
24 And see if there is any wicked way in me,
And lead me in the way everlasting.
 
This Psalm is my prayer today; that God would help me to have a pure heart before him and that He would lead me.
Often times, we try to cover our sin or forget about our sin.  If we read through the full chapter of Psalm 139, we understand that God sees all and knows all.  Trying to hide ourselves or cover our sin doesn't work.  Instead of running from God, we need to run to him for help, forgiveness, and Salvation.
