"Job never knew why God allowed him to suffer. He never knew. 
But he came to the point where he believed that God knew, 
and he was prepared to leave the answer with God. 
That is the secret. 
I have never met anyone yet who ‘conquered’ suffering 
properly and hadn’t come to that same point: 
I don’t know why, but I believe God does and I am going to trust Him.”
