Not that which goes into the mouth defiles a man; but that which comes out of the mouth, this defiles a man. Mat 15:11 What comes out of our mouths is evidence of what is in our hearts.

A good man out of the good treasure of his heart brings forth that which is good; and an evil man out of the evil treasure of his heart brings forth that which is evil: for of the abundance of the heart his mouth speaks. Luk 6:45 The Lord is good and anyone who aspires to be good must be filled with the Lord the Holy Spirit.     He it is that manifests good in us.     Phi 2:13 Our hearts must be transformed by the power of the Word and the Holy Spirit.
