Sometimes things happen that no one can explain.

There is so much tragedy in this story that I don't even know where to begin.
My parents have very good friends, Ron and Diane Toews whom they have known since Bible School days. Our families got together occasionally growing up and I remember their kids as being talented, good looking and kind hearted. Yesterday my dad called me with the news that their son Nathan had been killed on Friday. He was 23. He, his wife, his brother and his 8 month pregnant sister-in-law were travelling to Calgary so Nate could lead worship in a friend's wedding on Saturday. As Nate was driving, an oncoming semi lost control and the trailer hit the Toews' car. Nate died instantly, his sister-in-law who was in the passenger seat is in critical condition (they delivered the baby and the baby boy is fine...named after his uncle who never got to meet him) and the two in the back seat were fine. Well, physically fine.
Nate and Rosanna were newly-weds, married less than 2 years I think. Now she's a widow.
Nate had just started a new job as the worship pastor at the church where my brother serves as the youth pastor. They're good buddies and my brother was so excited to be able to work with Nate. A church is without a pastor now.
Ron and Diane were on their way back from Africa when the accident happened. There was no way to reach them. They arrived at the airport last night to the news that their son was dead, their daughter-in-law might not make it and their world was entirely different.
I don't know what breaks my heart the most.
Situations like these make me wonder where the good is. How is God working in this? I know he is, but it sure is hard to see through all the tragedy. I spent a lot of time last night asking God why this had happened. A young woman's dreams for a life with a husband, raising a family, are shattered. Brothers who have lost a best friend. A newborn baby who will never know his namesake. A younger sister who has lost a role model. Parents whose hearts are broken. How do you explain this?
If you're the praying type, now would be a good time.
