Elihu

It's been said time and time again: Do not let anyone look down on you because you are young. It has been said so often, in fact, it could almost be considered a cliche; a distant, overused combination of words that has been said so many times, it looses its meaning.
Of course, when you first hear a phrase, it actually registers in your mind; you process it. Many of us don't even process some of life's greatest lessons anymore, just because we've been exposed to them time and time again, and the desire to listen to it again-what is sure to be another boring lecture-doesn't exist.
"Do not let anyone look down on you because you are young". In the book of Job, many of the church elders are trying to give Job "helpful" advice. Each one's view on why God allows the righteous to suffer, however, was inaccurate.
I don't know about everyone else, but when I am getting advice, it usually takes awhile for the advice-givers to get to their point. I imagine that these lectures took sometime to get through.
Elihu, unlike the 3 men who were trying to give Job guidance, was young. He was new to this. He kept quiet all throughout the long, inaccurate lectures, because he was afraid it would be disrespectful to speak up.
But sometimes are voice is all we have.
Luckily, he wised up. In AIV (Autumn's International Version), he basically tells them "Hey, I didn't want to say anything because I'm too young, but I have to say that I must disagree with all of you. Job, suffering can be a door into spiritual growth and development." Of course it was a lot more complex than that, but Job finally understood why all this was happening. Because Elihu had guts. Because he put fear behind him. And because a young kid spoke up and used his voice.
