2 Corinthians 10:5

Casting down arguments and every high thing that exalts itself against the knowledge of God, bringing every thought into captivity to the obedience of Christ.

Arguments come from the Devil.  They are those little seeds of doubt that float through our minds that we don’t cast out. If a thought doesn’t line up with the Word of God, we are to get rid of it and cast it down.  A thought proceeds every action we do, whether good or bad, and we can control them.  The knowledge of our abilities and power to control what we think is given to us by God.
