Asking 'Why' in the Wake of Parents' Divorce

Tullian Tchividjian tells the following story about trying to deal with the pain of his parent's unexpected divorce:
I remember going to see [the Christian counselor] Larry Crabb, who was [a colleague of] my father. "How's your mum and dad doing?" Larry asked.
"Larry, I don't know what to do. Seriously. I feel like my whole world has been turned upside down. I don't get this. It's excruciating."
Larry said something remarkable. He could see that I was trapped in the prison of Why, banging my head against the bars. He said,
Tullian, listen to me: The "why" is none of your concern. This is not your burden to fix or figure out. You are not responsible for your parents' relationship or their reputation, or even your own reputation. Those are in God's hands, and his ways are his, not ours. When it comes to God's will, the sooner you can get out of the conjecture business, the better. If you don't go to your grave confused, you don't go to your grave trusting. Painful as it is, this situation gives you an opportunity to show them grace, to love them in their brokenness in a new way. Which is precisely what Jesus has done for you and continues to do for you.
Larry preached the Gospel to me that day, and it made all the difference.
