For TRUTH IS! "If any man thinks that he knows anything, he knows nothing yet as he ought to know"! (I Corinthians 8:2) http://asimpleandspirituallife.blogspot.com/2015/09/knowledge-falsely-so-called-i-timothy.html
For it's not that which "i know", but that which i have Graciously been allowed to see(experience) and/or hear(receive) concerning The TRUTH that Truly matters!
If, and when, a soul finally begins to grow ^up-ward^, evermore "trusting in The LORD with all their heart"! It is then a soul begins to Truly REALize that the only thing i know IS, "I(ego,id,self,pride) don't know"! (Proverbs 3:5) http://asimpleandspirituallife.blogspot.com/2009/05/i-must-die.html
