The human mind constantly works to form thoughts in orderly and coherent ways.  It is not always an easy path.  Sometimes we do not think clearly.  The Word of God is the way that our thoughts can become untangled.  We really do need the teaching of holy scripture.  We need the Word of God to correct our thinking and to reprove our behavior.  Untangling our thoughts is the first step in getting our lives untangled.  

“All Scripture is inspired by God and profitable for teaching, for reproof, for correction, for training in righteousness; so that the man of God may be adequate, equipped for every good work” (2 Timothy 3:16-17, NASB).
