Do everything without grumbling or arguing, so that you may become blameless and pure, “children of God without fault in a warped and crooked generation.” Then you will shine among them like stars in the sky as you hold firmly to the word of life. . . . – Philippians 2:14-16 (NIV)
Now Jesus stood before the governor, and the governor asked him, “Are you the King of the Jews?” Jesus said, “You have said so.” But when he was accused by the chief priests and elders, he gave no answer. Then Pilate said to him, “Do you not hear how many things they testify against you?” But he gave him no answer, not even to a single charge, so that the governor was greatly amazed. – Matthew 27:11-14
Silence can say a lot. Sometimes words are not enough for the most important of messages. Sometimes the most effective answer is to say nothing.
