How we think affects how we feel and how we live. One of the few things that we can control is our thoughts, if we choose to think in line with God's word. It is not only that we should read and think about the Scriptures, but that we also keep our thoughts in a healthy place by focusing on the right things in life.

Paul encouraged us to think on healthy "things" that are true, honorable, right, pure, lovely, admirable and things that are excellent and worthy of praise. 

Add to this, being doers of the Word, and the result is "The peace of God will be with you!"
