One of the biggest deceptions to man is what goes on in his heart.  Hidden motives of the heart exist in each one of us, and until we take time to dig down deep, we may not even realize what's going on inside.  Jealousy, anger, bitterness, greed… these all come from the heart.  I think that's why I love the prayer of David who asks for God to create in him a clean heart.  We all need to take time to clean out our hearts so they can be refreshed and renewed.  How clean is your heart?  Is there anything you need to be cleansed of?  Is there anyone you're mad at?  Is there anyone you're jealous of?  What about someone who hurt your feelings?  Do you need to forgive anyone?  Sometimes we just need to take some time to allow the Lord to clean out our hearts.
