I read this book by Elie Wiesel. Not only did it make me tear, it made me ask, why allow such horror?
An excerpt, though not the most emotive one:
There was no longer any joy in his eyes. He no longer sang. He no longer talked to me of God or the cabbala, but only of what he had seen. People refused not only to believe his stories, but even to listen to him.
I sincerely believe that God is good all the time, and I recognize that there are forces of good and evil constantly at work.
In the end, I choose faith - in Him who's ever faithful.
