What is Truth? John 18:37-18:38 This sermon deals with the truth in the world, what truth is and what lies are. John 18:37-38 Pilate therefore said unto him, Art thou a king then? Jesus answered, Thou sayest that I am a king. To this end was I born, and for this cause came I into the world, that I should bear witness unto the truth. Every one that is of the truth heareth my voice. Pilate saith unto him, What is truth? In my opinion, this is one of the most important questions in scripture. Pila.
