Liars mock and spit at the truth.
It used to bother me that when Pontius Pilate asked "What is truth?" Jesus didn't answer. I remember preparing for Confirmation, and the priest who came to check on us asked us "What is truth?" No one answered. I made Fr. K spit out his Schweppes ginger ale when I raised my hand and said even Jesus couldn't answer that. Fr. K then told us to read John, and find out. He'd go over it with us the next week. I kept looking at the trial scene rather than at chapter 14 to find out, and I was lost. Unfortunately I was sick for the next class and missed that session. Even though I later read John 14:6, I was very much bothered that Jesus didn't defend Himself.
But now I read it and I see that He must've understood that no one was interested in the truth. Lies were told to convict Him. Pontius knew that, and still He cared nothing for the truth, and appeased the crowd. Jesus said in Matthew 7:6 “Do not give dogs what is sacred; do not throw your pearls to pigs. If you do, they may trample them under their feet, and turn and tear you to pieces. " They had made up their minds to trample the truth. What more was there to say?
