Can Anything Change What You Are Confident In?

I currently reside in the foothills of Appalachia. Pick-up trucks are numerous here. Many who own and operate them become emotionally attached to one particular brand. Some go so far as to place stickers on their vehicles coarsely jesting about a competing brand: whether those other brands are able to do what they think their brand of pick-up truck will. This approach is almost certainly without merit. 

In recent years, some automakers which previously had not manufactured pick-up trucks began to. Although they made reliable cars, they have had some difficulty breaking into the pick-up market: meaning they did not sell many. The thing those new to that market must do is this: continue in their attempt to increase the performance of their manufacturing. Then, they will eventually begin to influence those who are MOTIVATED BY EXCELLENT PERFORMANCE, even if they had been motivated easily by emotion.

"For though we walk in the flesh, we do not war according to the flesh. For the weapons of our warfare are not carnal but mighty in God for pulling down strongholds (emotional approaches that may cause us to reject HIS MOST EXCELLENT WAY), 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, and being ready to punish all disobedience WHEN YOUR OBEDIENCE IS FULFILLED."  

When our Lord's obedience is being fulfilled in us, all confusion and unfruitful emotion is overcome!
