A Failure to Give Thanks is Far More than Impolite:

A failure to be thankful is not an indication that you are not polite.  It is clear evidence that you are not right.

 

Psalm 100 is one of those scripture passages that gives clear reason why we should be thankful.  Gratitude should abound because of who God is, what he has done, in light of how his faithfulness is constant, and considering that his lovingkindness toward his people is without limit.  

If you don't know these things about God, that is a problem.  Knowledge of the Most High is the highest form of cognition.  The Apostle Paul said his desire was to know Him, and he looked forward to the day when his knowledge of God would be much greater (Philippians 3:7-13, 1 Corinthians 13:12, also Psalm 83:18, & note inDaniel 4 the goal of bringing a proud King to a knowledge of the Most High.)  If one does not have a knowledge of God, especially in an environment like the one where most of us live, where His  witness is strong, that is a problem.  If one knows God, and yet refuses to be thankful, the problem is even worse.  (See here in Romans 1.)  

 

Thankfulness to God is the altimeter.  Ignore it too longand the ground will meet you in a very violent manner.

 

Not being thankful is not simply impolite.  It is wrong--wrong in a deadly sort of way.
