2 Corinthians 10:5

We are destroying sophisticated arguments and every exalted and proud thing that sets itself up against the knowledge of God, and we are taking every thought and purpose captive to the obedience of Christ. 

As we develop in the faith, we build our stand on the word and our ability to stop destructive thoughts. We can recognize the wrong path and beliefs going in the wrong direction. We no longer are bystanders to the flesh and accept everything that comes to our mind but destroy those arguments.
