Help me watch my mouth

In Psalm 141:3, David prays that God will help put a watchman over his mouth.  David was concerned that he would not say the wrong thing.  His prayer was that he would say the right thing at the right time for the right reason.  Our speech can be such a blessing or curse it just depends on who is in control of it.  We have all met people who talk before they think things through.  Mark Lowry calls them a talk thinker.  They are people that talk before they think or while they are talking they are formulating their opinion.  The problem with this way of thinking is that while they are talking they are convincing themselves of other things.  David looked at his mouth a portal of blessing or cursing.  Out of our mouth can come great pearls of wisdom of foolish destruction.  James calls the tongue an instrument that needs to be controlled.  He also calls it a torch of destruction.  What is amazing about this part of our body is that on one hand we can praise God and in the next moment we can curse man who is made in the image of God.  One moment we are happy about life and the next we are complaining about our lot in life.  The reality is that our mouth only talks about what is in our heart.  So today let the Lord fill you too capacity with His love and grace and that is what will come out of your mouth.  Be like David and ask the Lord to put a guard at the door of your mouth and when you talk make a conscience decision to be a person who blesses and encourages.
