John 18:37 - How would you answer Pilate?

Joh 18:37 Pilate said to him, "So you are a king?" Jesus answered, "You say that I am a king. I was born for this, and I came into the world for this: to testify to the truth. Everyone who belongs to the truth listens to my voice."
Joh 18:38 Pilate said to him, "What is 'truth'?" After he said this, he went out to the Jews again and told them, "I find no basis for a charge against him.

You are standing in front of Pilate or another that has asked the question, "What is 'Truth'?". How do you answer him?

(The answer must be in context to John 18:37, Christ's reply, "....to testify to The Truth. Everyone who belongs to The Truth listens to my voice".)
