Our Scripture reading today is Colossians 3:16, "Let the word of Christ dwell in you richly in all wisdom; teaching and admonishing one another in psalms and hymns and spiritual songs, singing with grace in your hearts to the Lord."
 
As we allow the Word of God to dwell in us, we will be rich in what is important and poor in the things that do not matter for eternity.  It is very important that we guard what we allow our minds to meditate on.  What kind of music we listen to can really make a difference in whether or not we are pleasing God or not.  Is someone really thinking about the grace of God while listening to fleshly music?  I would say this is highly unlikely.  What are we reading by way of books or the internet?   
 
Keep putting God's Word into your mind.  It will flush out everything that is causing you mental anguish.  Ephesians 5:26, "That he might sanctify and cleanse it with the washing of water by the word,"
