Read Psalms 139:23&24  King David is asking a hard thing of God in these 2 verses.  And we should ask the same thing of God.  King David is asking God to check him out.  King David is asking God to tell him about any problems that God sees in David’s life.  We can’t see our own hair – except in a mirror.  When we are getting ready for church, sometimes our mother says, “Come here and let me see how you look.”  We can’t see our own hair, but our mother can see it.  She may say, “Here, let me fix your hair.”  And then she begins to comb our hair and to make it lay down.  If our hair is sticking up in the back and we go to church that way, some of the kids will laugh at us.  But if someone who loves us sees our hair sticking up, they will stop us and tell us that our hair is sticking up and help us to fix it so that we won’t be embarrassed and look silly.  God is someone who loves us and doesn’t want us to look silly.  We should ask God to show us problems in our life that we ourselves do not see.  We should ask God to point out anything that is wicked in our lives so that we can clean it out.  I want to be clean in front of God, don’t you?  When God speaks to your heart and shows you something that is wrong inside of you, be brave and ask for forgiveness and ask God to clean your life out.  Listen to God’s Word and obey it – you will be happy if you do.
