The Word of Truth = The Gospel

So says Paul in Col. 1.5. If Pilate had only understood this. When he asks Christ, "What is truth?" (John 18.38), Christ doesn't bother explaining to Pilate because Pilate obviously was not open to what exactly truth was. He commands/allows the murder of Christ (heeding the predetermined plan of God by making his own choices—a mystery). A guy who is going to let an innocent man be murdered in the most heinous manner is not a person who is open to hearing the truth; however, it does explain why he allows Christ to die. If one does not believe in absolute truth, then whatever is expedient is fine.
