Read Job 16
Focus on verse 2
A saying that we used to chant at each other on the playground when I was a child when we were called a derogatory name was “sticks and stones may break my bones but words will never hurt me”. While the intention behind this little diddy was to strengthen the resolve of those on the receiving end of hurtful words, it unfortunately is not entirely true. Words can have a significant effect on us and can leave deep and lasting wounds that scar us psychologically particularly if we believe that the words are true. The best defense against hurtful words that are spoken against us is to know and believe the words that God speaks toward us in regard to His love and grace towards us.
Job apparently did not find the words of his friends very comforting. In fact, it would seem he found his friends more comforting before they started talking, when they were simply sitting in silence with him. What sustains Job in the midst of the verbal assault that they release upon him is his knowledge of God and the relationship he has with Him.
The intention of Jobs friends was clearly to help him, they do not realize until they hear the Lord speak that their efforts are misguided. The wise writer of Ecclesiastes says, “There is a time to speak a time to be silent”. I’m going to guess that a good time to be silent is when we are uncertain that what we are about to say is consistent with what God would say.
